Architecture / Empire / USA

ColonialSpanish (1492-1898)

Colonial architecture : Architecture transplanted from the motherlands to overseas colonies, such as Portuguese Colonial architecture in Brazil, Dutch Colonial architecture in New York, and above all English Georgian architecture of the 18th century in North American colonies.

Colonial: The architecture of, particularly, America when it was a colony.

Mission Style: A style of architecture associated with that of early Spanish colonial missions in Mexico and the southwestern U.S., mainly in the 18th century.

Southern Colonial: An architectural style characterized by: one story or a story and a half, two end chimneys, brick (sometimes timber) construction, linear floor plan (i.e. one room deep), steeply pitched gable roof, and (sometimes) decorative treatment through the use of a variety of brick bonds and classical features (e.g., modillioned cornices, molded stringcourses, etc.).

Spanish Colonial style: An architectural style best known by the simple adobe to imposing Baroque inspired missions of the Southwest. Domestic architecture characterized by: single story structures with flat or low pitched roofs, stucco covered stone or adobe brick walls, multiple doors, and sometimes verandas as well as courtyards (patios) with corridors (interior verandas).

ColonialFrench (1524-1803)

Creole house: Originally a person of European ancestry born in the West Indies or Louisiana during the French Colonial period. Soon expanded to include the descendants of French soldiers and African-West Indian women. Finally, it came to distinguish one likely to be of mixed racial and cultural background who, unlike strangers and foreigners, spoke the Creole language and was well acclimated to the complex culture and difficult environment of the New Orleans area.

Creole architecture: That of peoples of European descent in tropical and subtropical America – French, Spanish, English, etc., in the West Indies; French and Spanish in New Orleans, and the like. The term Creole differs in its special application, but means always, born in the new country of pure European stock; and this applies to cattle, poultry, etc., as well as to mankind.

Colonial – British (1607-1783)

Georgian Colonial architecture: The architecture of the British colonies in North America from 1714 to 1776.

Georgian: The architecture of the British colonies in North America from 1714 to 1776.

Georgian Colonial: The architecture of the British colonies in North America from 1714 to 1776.

Georgian motif: The architecture of the British colonies in North America from 1714 to 1776.

Early Classical Revival: The Early Classical Revival style (1770-1830) can be considered a transitional style between the Federal and Greek Revival styles. In common with Georgian and Federal houses, an Early Classical Revival house usually has its long axis parallel with the street and a symmetrical facade; but the front facade usually features a portico or entrance porch supported by columns of Greek or Roman design, and the rooms are often arranged less symmetrically than in Georgian and Federal houses.

eyebrow window heads: A small window, which can be opened, built into the frieze of some Greek Revival houses.

eyebrow window: A small window, which can be opened, built into the frieze of some Greek Revival houses.

Greek Revival style: The final years of the 18th century brought an increasing interest in classical buildings to both the United States and Europe. This was first based on Roman models (Federal style), but archaeological investigation in the early 19th century emphasized Greece as the Mother of Rome which, in turn, shifted interest to Grecian models. The style is an adaptation of the classic Greek temple front employing details of Doric, Ionic or Corinthian order.

Greek Revival: An architectural style characterized by: low-pitched gable (or sometimes hipped) roof, a frieze, a pedimented gable, a porch (or portico) with usually non-fluted columns, insignificant chimneys, elongated six-over-six double hung windows, a four panel door flanked by side lights with a transom window above, and bevel siding.

corner-entry: The corner-entry house, a common substyle of Greek Revival, has an asymmetrical facade in which the main entry door is located at one end, adjacent to a front corner of the building.

Romanticism: Late-18th to early-19th c. artistic movement, its many variations and strands defying any neat definition. The one characteristic found throughout its sundry manifestations was the insistence on individual experience, intuition, instinct, and emotion. Commonly perceived as a reaction against the rationalism of the Enlightenment, Classicism, and Neo-Classicism, it nevertheless shared with Classicism reverence for the ideal, transcending reality, hence the term Romantic Classicism applied to works displaying a Romantic response to the Antique…

Romantic Classicism: See Romanticism.

Cape Cod cottage: Originated with English settlers in the mid-1600s; although it is associated with the early Colonial period, the type actually prevailed well into the 1800s. The basic form consisted of a one- or two-room house with a loft above, and, often, a lean-to at the rear. Sometimes a third room was added at the end. A pitched, bowed, or gambrel roof sloped down just to the window tops. Built low and broad to withstand prevailing winds, the shingled or clapboard Cape Cod cottage often sat directly on timber sills without a foundation. If the sandy soil underneath eroded or blew away, the house could be dragged or floated to a new location.

good morning stairs: In a full Cape house, the front stairs leading from the front hall to the attic rooms; at the chimney block the stairs turn both right and left, serving both sides of the house.

New England houses: Like the Cape Cod cottage, this structure derived in the early 19th century from the central chimney hall and parlor cottage of New England. Two front rooms sit at either side of an entrance lobby from which a stairway ascends to two rooms in a half—story. Several smaller rooms are arranged across the first floor rear. Commonly, “lie-on-your-stomach” or “ankle” windows located below the eave of the gable roof (often in an entablature) light the upstairs rooms.

Cross House: A house with a cross-shaped plan where a building element intersects with the rectangular main structure, usually at the center entrance, and extends through the house to the rear, particularly in the 17th century Chesapeake Bay region.

temple form: A late-18th-century Virginia three-part house, consisting of a two-story central block with a lower form on either side, smaller than the grand plantation houses of the period.

center-passage plan: A two-room floor plan with an entry and central corridor dividing the house. A refinement of the hall-and-parlor house, particularly in Virginia and Maryland from the later 18th century on.

pattern book designs: Imported beginning in the 18th century, a book of drawings intended as a guide for American housewrights and carpenters to the popular English styles of the time. In the 19th century, pattern and plan books were published in the United States by American designers and were very influential in promoting specific styles and philosophies for living.

Shaker architecture: The Shakers (or United Society of Believers in Christ’s Second Appearing) were founded by the English-born Ann Lee (1736-84), who emigrated to America (1774) and gathered around her sufficient followers to establish a religious sect. Believing that odd or fanciful styles of architecture, with moldings, cornices, etc., should be eschewed, the Shakers created plain meeting-houses in which they could perform their ’round dances’ that were part of their ritual, so large areas of floor-space were essential. Believing also that light and cleanliness were the antithesis of evil, buildings had numerous windows

loophole: For defensive purposes in Colonial times, a narrow vertical opening in the exterior wall from which to observe the enemy and return fire. In masonry construction, the sides of the opening are splayed, making it much wider on the inside.

cross-buck: Four triangles pointing inwards, whose outside edges form the shape of a square. Common in doors and Colonial architecture.

gauge: To rub brick for contrast in color and texture to adjacent brickwork, as in colonial Virginia. 2. To add lime putty to cement mortar. 3. To slow the setting of plaster by adding a substance such as glue. 4. To hasten the setting of plaster by the addition of plaster of Paris. 5. The measure of thickness, of sheet metal; or of wire, the diameter. 5. The spacing of tufts across the width of a tufted or knitted carpet, expressed in fractions of an inch. 6. The portion of the length of a shingle, slate, or roofing tile left exposed to the weather when laid in place. 6. Any of various standards for designating the thickness or diameter of a thin object, as the thickness of sheet metal or the diameter of a wire or screw. Also, gage.

gouge work: Incised woodwork for which the gouge is the principal tool, as in trim and mantels of the so-called Dutch Colonial architecture of New Jersey and Pennsylvania.

Stone-Ender: A gable-ended, timber framed Colonial house strongly associated with early Rhode Island and known for the massive fireplace that constituted nearly the entire end of the house as seen from the outside.

garrison house: An early American fort to protect settlers from Indians. 2. A colonial house, of logs or heavy timber, whose second story projected beyond the first-story façade.

Adam: The first “American” style of architecture, based on English Georgian.

Federal: The first “American” style of architecture, based on English Georgian.

Federal style: The first “American” style of architecture, based on English Georgian.

Colonial entrance: Colonial entrances rely on engaging a classical front.

Colonial treatment: Design evoking historic styles of the Colonial era.

jettied story: An upper story of a building that projects out over the story beneath it, common in Colonial American architecture.

colonial siding: Wide, square-edged siding boards used extensively in early American construction.

Hall-and-Parlor: A two-room plan common in the English colonies. The hall served as a general reception, entertaining, and work space while the parlor was usually for sleeping, although there were many variations.

ColonialDutch (1609-1664)

Dutch brick: A brick used in house construction in colonial U.S.A., 1 1/2 by 3 inches by seven inches; smaller than the English brick which was adopted later.

Colonial – Swedish (1638-1655)

German/Swiss Colonial style: Germanic housing in the colonies was typically well built and designed for efficiency. One of the earliest Germanic building types in Pennsylvania was the tripartite house, which reflected the Old World tradition of combining a house, a threshing area, and a stable under the same roof. For convenience, a springhouse was often incorporated directly into a dwelling, which might also include an attic meat-smoking room, or Rauchkammer, connected to the chimney stack. Particularly practical building types were the bank house and bank barn, built into a ground slope to provide cool lower-level storage rooms. The majority of early Germanic houses in America were simple, well-built log dwellings, although it is mostly the stone buildings that have survived. Stone, considered a status symbol, was favored primarily by the rural gentry. The typical Germanic plan was asymmetrical three-room layout, placing the kitchen (Kich, in Pennsylvania German) on the main level, usually to the right of the chimney. To the left was the stove room (Schtupp), with a sleeping chamber (Kammer) in the rear. By the mid-1700s, many Germanic settlers had adopted the Georgian center-hall plan.

log buildings: Although the Swedes were the first settlers to build log structures in America, the major tradition of log building here originated independently in the late 1600s to the early 1700s with German-speaking settlers in the mid-Atlantic region. From Pennsylvania and Virginia, the tradition of log building began spreading south and west with migrating Germans and Scots-Irish in the 1730s and reached its height during the period of frontier expansion from the mid-18th to mid-19th centuries. The basic log house form was the one-room, or single-pen, plan. The central-chimney “saddlebag” plan evolved when the single-pen house was enlarged by setting the gable end of a second log building against the chimney of the existing structure. An easier way to add on to a log house was to place a second cabin next to the first, gable to gable, and simply roof over the intervening space, producing the “dogtrot” (two pens and a passage) house. Pine and spruce were the preferred woods.

United States of America

George Washington, 1789-1797
John Adams, 1797-1801
Thomas Jefferson, 1801-1809

Neoclassical Architects: In America, these included Thomas Jefferson (1743-1826), William Thornton (1759-1828), Benjamin Latrobe (1764-1820) and Charles Bulfinch (1763-1844).

romantic: The early 19th century Neoclassical (which see) architectural styles are referred to as “Romantic” because, unlike the preceding Renaissance Classical (which see) styles which appealed to the intellect, they appealed primarily to the emotions. The various 19th-century Revival styles (Greek, Gothic, Egyptian, etc.), as well as the Italianate and Italian Villa styles, are considered Romantic.

Jeffersonian Classicism: A Neoclassical style based on Roman public buildings and strongly advocated by Thomas Jefferson.

Roman Classicism: Typical of Roman Classicism is the one-story Roman temple form employing variations of the Roman orders. The raised first floor is characteristic of design inspired by the proper Roman temple built on a platform or podium. The four-columned portico with pediment enclosing a lunette is one of the most often copied features in the Roman idiom which was popularized by Thomas Jefferson (1743-1826). Generally classical moldings are left plain without enrichment and painted white.

Roman Classicism style: Neoclassical version inspired by Renaissance-inspired Palladian Neoclassical style. Thomas Jefferson owned three copies of Palladio’s books and used Palladian ideals in designing Monticello, etc. This vision of Neoclassicism competed with the simpler Federal style.

Roman Revival: A style that uses architectural and design elements from the Romans. Often involves masonry, arches, and large-scale structures. See Classic Revival.

American Directory: Directorie provided the inspiration for American Directory (c. 1805-30) – a variant of the USA Federal style (1776-c.1830) in general terms, except that the favored motifs in the USA were those of Freemasonry.

James Madison, 1809-1817
James Monroe, 1817-1825

White House: In Washington, capital of the U.S.; the official residence of the President, finished in its present form in 1818.

American Order: Capital resembling that of the Corinthian Order with acanthus leaves replaced by corn-cobs, corn-ears, and tobacco-leaves, invented by Latrobe for the US Capitol in Washington, DC.

corn-cob: Carving of the woody receptacle to which the grains are attached in an ear of maize, used in a variation of the Corinthian Order invented by Latrobe for the US Capitol Building, Washington, DC, after 1814, and called the American Order. Corn-cobs recur as 19th c. finials, popularized by Latrobe’s designs.

plantation: In the 19th century, a large, often immense, agricultural operation owned by a single person or family. It concentrated on a particular cash crop, such as cotton or tobacco, typically relying on slave labor. In the Colonial period, plantation was synonymous with farm.

John Quincy Adams, 1825-1829

baggage room: In the United States, a room in a railway station for receiving, checking, and handling baggage.

engine house: In the U.S., a building primarily for housing a fire engine… 2. A building connected with a railway for housing locomotive engines.

Andrew Jackson, 1829-1837

Monterey: A style (c. 1830) originating before the Anglo-American cultural assault on California. Characterized by a pitched roof, adobe construction, and second-level balconies.

Martin Van Buren, 1837-1841
William Henry Harrison, 1841
John Tyler, 1841-1845

Gothic Revival style: The romantic revival of largely Gothic detail in the 1840s.

Carpenter’s Gothic: Whimsical, unscholarly Gothick derived from pattern-books of e.g. Batty Langley. 2. 19th c. timber buildings in the USA with Gothicizing tendencies, e.g. in barge-boards.

Renaissance Revival: Design recalling the Italian Renaissance architecture of the 15th century. In the United States, note the relatively minor Italian Renaissance Revival of 1840-60 and the academic Second Italian Renaissance Revivals of 1880-1935.

James Knox Polk, 1845-1849
Zachary Taylor, 1849-1850
Millard Fillmore, 1850-1853

Byzantine Revival: The re-use of Byzantine forms in the second half of the 19th century, typically in churches, often characterized by multiple domes, round-arched windows, and ample decoration.

Romanesque Revival: The reuse in the second half of the 19th century of massive Romanesque forms, characterized by the round arch.

Romanesque Revival style: The reuse in the second half of the 19th century of massive Romanesque forms, characterized by the round arch.

Romanesque commercial building: The Romanesque commercial style was not as widespread as the Italianate. Nor was the style so easily accomplished in vernacular building, since it was often combined with what is now called Queen Anne detailing. The Romanesque was a picturesque mode of expression. At its most ambitious level, the vernacular Romanesque used coursed, rock-faced sandstone blocks with round-arch windows and a low, wide, arched entrance. Emphasis was on surface texture and the rhythm of the arches or arcades…

octagon house: A Victorian house having eight sides; especially found in the Hudson Valley of New York.

Franklin Pierce, 1853-1857

bessemer process: Bessemer steel is made by pouring molten iron into a bottle-shaped vessel lined with refractory material, and blowing air through the iron until the carbon and silicon are burned out. The combustion of the carbon and silicon produces sufficient heat to keep the mass thoroughly melted. If the lining of the vessel is silicious or acid all the phosphorus and sulphur remain in the steel. By the Thomas Gilchrist method a basic lining is used, and the steel is made free of phosphorus.

James Buchanan, 1857-1861

institute: In the United States, the American Institute of Architects, first founded in 1857, not at first a general body embracing chapters in the different cities.

AIA: The American Institute of Architects. Members are permitted the use of the letters following their names. Fellows use F.A.I.A.

French Renaissance Revival style: The Renaissance Revival styles of the 1860s and 1870s marked the first period in which fine designs were used for mass-produced furnishings.

Second Renaissance Revival: Buildings in the Renaissance Revival style show a definite studied formalism. The tightly contained cube is a symmetrical composition of early 16th century Italian elements. Characteristics include finely cut ashlar that may be accentuated with rusticated quoins, architrave framed windows, and doors supporting entablatures or pediments. Each sash may have several lights or just one. A belt or string course may divide the ground or first floor from the upper floors. Smaller square windows indicate the top or upper story.

Italian Renaissance Revival: Arriving in the late 19th century, this style was a much grander interpretation of northern Italian Renaissance villas and palaces than the earlier Italianate and Italian Villa styles, resulting in more luxurious mansions.

Abraham Lincoln, 1861-1865
Andrew Johnson, 1865-1869
Ulysses S. Grant, 1869-1877

General Grant: The good general was a passive participant in this mid-Victorian eclectic melange – usually ornate wood houses with mansard roofs.

mansard cottage: Throughout 1870-80 the cottage with a mansard roof was referred to as a French cottage, and historians link this cottage to the development of the Second Empire style. In vernacular design the French cottage was less Second Empire than the design of high-style buildings, and it was more generally French. One could argue that it was a hybrid affair with Italianate features, and that over time it absorbed other kinds of cottage detailing.

bay-front double house: The bay-front double house, primarily a 19th-century building, was a two- or three-story structure with several roof options: a mansard roof, a gable roof with the ridge parallel to the street, or a flat roof and accompanying parapet. The primary design scheme required a full-height, usually three-sided bay window or pavilion on each end that flanked a double entrance. The bays terminated in their own roofs. Dormers were frequently built on these units to utilize attic space, especially on those with mansard roofs

three-family house: The triple decker, a unique three-family structure, originated in New England mill towns and cities. Constructed from about 1870 to 1920, the triple decker, could absorb cottage details even though it had outgrown the cottage scale. Most were long, rectangular buildings with the narrow side toward the street that provided three living spaces, one family to a floor. Most stacked one unit over the next, and ground-level motifs were repeated throughout an elevation. The main entrance, which might have an entrance porch, was on one side of the facade. Bay windows were common on either the facade or a side elevation. Roof treatments included flat roofs with an overhanging cornice, and gable-to-the-street roofs with a closed gable. Regardless of the facade porch treatment, most of these buildings had rear-access porches on all three levels…

Colonial cottage: From 1870 to 1940 several Colonial Revival houses developed; this section deals with two of them. The fervor for American culture that swept the country after the 1876 Centennial resulted in the revival of two house types, the New England eighteenth-century cottage of English medieval origins, and the Georgian. Well into the twentieth century the vernacular tradition included these in its inventory, as well as the Dutch gambrel, the so-called Cape Cod, and the large hipped and pedimented cottages with colonial motifs, which are all discussed in other sections…

center-gable cottage: The center-gable cottage has a long history of development that seems to emerge from the application of gables to Gothic revival houses. During the period 1870-1940, the gable itself, while always aligned over the entrance door, lost its narrow, steeply pitched gable roof and widened to function more properly as a dormer. This house, built during the period 1870-90, was rectangular in shape, with the Wide side toward the street, and has a central hall plan with four rooms to each floor. The center gable was a frame house with clapboard siding, although shingles were later used in gable ends. The fenestration was symmetrically arranged in three bays. The house had a porch that was shallow in the older models and shallow but wide in the later ones. The porch carried its own roof supported by square posts

hipped cottage: The hipped cottage is a generic house type that was built throughout most of the 1870-1940 period. It had the unique ability to be rendered in many styles, from Italianate to prairie, and could be adapted to most climatic conditions. This cottage was a classic box characterized by a large hipped roof, an almost square floor plan, and compact massing often cubical in shape. In many parts of the country it has been called a four-square. But no matter what its name or form, it is a substantial and dignified house

apartment hotel: A building intended to be occupied in separate apartments; especially in American cities since 1870, a home for independent housekeeping by generally more than two families… Low-priced apartments are frequently called flats.

Italianate commercial building: In the Italianate storefront popular during the 1870s and 1880s, the window treatment (which included the shape and size of the window and the lintel or sill), the cornice line, and the corners of the building offered the most opportunities for detail from the limited design possibilities. Windows were generally long and narrow, and lintels and sills were of metal, brick, stone, or cement. Lintels were visually heavy units, segmented or rounded. Metal pieces had ornamented surfaces. The cornice was most often metal and had an entablature organization—architrave, frieze, and cornice—with heavy brackets at the corners and lighter, perhaps paired, brackets across the cornice. Façade designs that divided the first floor from the second had an ornamented beam or surface moldings that capped the display windows. The corners of buildings could be quoined in brick or stone, or pilasters or half columns might mark the edges and frame the lower level. It was also common to stack the upright elements on top of one another…

cast-iron: Iron, shaped in a mold, brittle, hard, cannot be welded; in the 19th century it was used in American commercial architecture, with cast-iron units used to form entire facades.

iron-front commercial building: The iron-front store was built in all geographical areas, the technology needed to produce iron architectural materials being almost as transportable as the materials. The mold makers had a predilection for classical details, so that most iron-front stores have at least a pair of plain pilasters at the corners or a set of stacked half columns with an entablature. Ironwork was integrated with pressed or stamped tinwork. While the iron posts and beams framed the facade, tin pieces were used for lintels or surrounds around the windows and for the large, bracketed, molding-heavy cornice. All metal pieces were painted to prevent rust

Two-Part Block style: The two-part block is the most common form for small and moderate-sized commercial buildings in the United States. This type of building is generally limited to two to four stories, and is characterized by a horizontal division into two distinct zones. The two-part division of the exterior zones typically reflects differences in its interior use. The street level indicates public spaces for commercial enterprises, while the upper section suggests more private spaces reserved for offices, meeting halls or apartments.

skyscraper: The method of construction developed in Chicago in which all building loads are transmitted to a ferrous metal skeleton, so that any external masonry is simply a protective cladding.

skyscraper construction: The method of construction developed in Chicago in which all building loads are transmitted to a ferrous metal skeleton, so that any external masonry is simply a protective cladding.

commercial style: The Commercial Style is a common term for the aesthetic that characterized much of early skyscraper design with steel and beam construction, large storefront windows, classical detailing, decorative cornices, and flat roofs.

false-front commercial building: The false-front commercial building has been associated with the settlement of the west, but false-front buildings were in fact built in upstate New York as well as in Iowa, Texas, Colorado, and Wyoming. The false-front has been associated with stores, and there is no doubt that the one- and two-story storefront is the most common of extant vernacular commercial buildings. This kind of building was used for services, small hotels, and as a meeting hall for social and fraternal organizations…

raft foundation: A foundation type developed in Chicago in the 1870s in which beams of either wood or steel are laid crosswise over piles and encased in concrete to form a pad for the base of a structural pier or column.

Chicago School of Architecture: Leading group of pioneer skyscraper architects, led by William Le Baron Jenney (1832-1907). Also see Second Chicago School of Architecture (c.1940-75) led by Mies van der Rohe.

arcaded block commercial building: From the last quarter of the 19th century right down to the present, much attention has been paid to the corner commercial building, particularly one marking the edge or the heart of a business district. The arcaded block was just such a building. It was intended to be an imposing building with a strong overall shape, solid massing, and firm lines on both its elevations. It was rarely uniform in size, for one elevation was often larger than the other, and one might have been designed somewhat differently from the other. As a corner property, the arcaded business block had a rich design vocabulary stemming from the history of business-block development after the Civil War and the introduction of a new sensibility. High-style architects such as H.H. Richardson and Louis Sullivan had demonstrated how an elevation could be integrated through the use of arches, round-headed elements, or arcades. The curvilinear elements were usually linked, which helped to break the wall away from domination by vertical bays. The new look presented windows in bands or clusters of light. This kind of design often gave a lighter feeling to portions of the wall and at the same time focused the design on the intersection of the walls. That corner often culminated in a tower that rose from a recessed or canted ground-level entrance

Richardsonian Romanesque: An architectural style characterized by: round arches over door and window openings, a heaviness of appearance created by rock faced stonework and deep window reveals, an asymmetrical façade, towers with conical roofs, porches with broad round arches supported by squat piers, and steep-gabled wall dormers.

Shingle style: An architectural style characterized by: uniform wall covering of wood shingles, hip or gable roofs with dormer windows, irregular roof line, small-paned windows, no corner boards, and a generally toned down appearance from that found with the Queen Anne style.

continuous business block: From the last quarter of the 19th century right down to the present, much attention has been paid to the corner commercial building, particularly one marking the edge or the heart of a business district. The arcaded block was just such a building. It was intended to be an imposing building with a strong overall shape, solid massing, and firm lines on both its elevations.

Sullivanesque: An intricate weaving of linear and geometric forms with stylized foliage in a symmetrical pattern is the unique element of the Sullivanesque style, originated by Louis Sullivan (1856-1924). Bold geometric facades are pierced with either arched or lintel-type openings. The wall surface is highlighted with extensive low-relief sculptural ornamentation in terra cotta. Buildings often are topped with deep projecting eaves and flat roofs. The multi-story office complex is highly regimented into specific zones – ground story, intermediate floors, and the attic or roof. The intermediate floors are arranged in vertical bands.

Rutherford Birchard Hayes, 1877-1881
James Abram Garfield, 1881
Chester Alan Arthur, 1881-1885

American Renaissance: The Beaux-Arts style, also called the American Renaissance, is about as formal as architecture can get. Based on classical European precedents primarily French and Italian palaces and palazzos of the 16th to the 18th century – this grandly formal style transformed America’s major cities between the 1880s and the 1920s after being introduced at the 1893 World’s Columbian Exposition in Chicago to an eager nation that had begun to tire of Victorian excesses.

Grover Cleveland, 1885-1889
Benjamin Harrison, 1889-1893

lenox: American china first manufactured in 1889 and considered competitive with European china.

skyscrapers: The Crystal Palace by Joseph Paxton at the Great Exhibition of 1851 was an early example of iron and glass construction, followed in 1864 by the first glass and metal curtain wall. A further development was that of the steel-framed skyscraper in Chicago around 1890 by William Le Baron Jenney and Louis Sullivan.

City Beautiful movement: The Beaux Arts style was popularized during the 1893 Columbian Exposition in Chicago. One outgrowth of the Expo was the reform movement advocated by Daniel Burnham: the City Beautiful Movement.

Academic Movement: The dominant influence in American architecture from the 1890s through the 1920s, emphasizing order and unity in design, expression appropriate to size and use, and adaptation of precedents drawn from a wide range of historical examples.

Mission Revival: Variant of American Colonial Revival which drew on the RC mission buildings in CA popularized from the 1890s after the World’s Columbian Exposition, Chicago, IL (1893). It is characterized by arcades, balconies, courtyards, and towers, with plain rendered walls and pan-tile roofs, and an absence of ornament or frippery…

Pueblo Revival: A predominantly Southwestern architectural style characterized by: flat roofs with projecting rounded roof beams (called vegas); stucco covered battered walls with rounded corners; multi-paned, straight-headed windows set deeply into walls; and stepped or terraced upper stories.

California mission: Celebrating the architecture of Hispanic settlers, Mission style houses feature arched dormers and roof parapets. Some resemble old Spanish mission churches with twin bell towers and elaborate arches. By the 1920s, architects were combining Mission styling with features from the craftsman and Prairie movements.

Territorial: An adobe style created by adding Greek Revival and other wood detailing to adobe homes in the Southwest, particularly in the Rio Grande Valley, in the late 19th century.

Grover Cleveland, 1893-1897

California bungalow: As built from 1895 to 1915—its first development period—the bungalow was known as the California bungalow. Because of the nature of the design and the kind of living which that design suggested, it was appropriate for this form to develop on the west coast.

colonial kitchen: In the late 19th- and early 20th-centuries, a kitchen inspired by the kitchens of Colonial America. A colonial kitchen is usually large, with a wide, open hearth, and contains no modern conveniences (or else contains modern conveniences contrived to look pre-modern). Colonial revivalists of the late 19th- and early 20th-centuries looked back upon colonial dwellings, especially colonial kitchens, with nostalgia for earlier, pre-industrial times. The colonial kitchen display of the World’s Columbian Exposition of 1893 in Chicago was exceedingly popular amongst Colonial Revival enthusiasts.

Elizabethan architecture: In the United States, the term often refers to late-19th- and early-20th-century English Revival architecture that used “black-and-whitehalf-timbering. Based vaguely on late medieval, rambling English cottages, it is often used interchangeably with Tudor.

Chicago Style: A style of architecture that originated with architects in Chicago in the late 19th and early 20th centuries; it featured the use of steel and larger window openings.

Colonial Revival: A revival of the architecture of the Colonial and Federal periods at the turn of the 19th into the 20th century.

Georgian Revival: A rediscovery of Georgian Colonial architecture in the late 19th and early 20th centuries as part of the broader Colonial Revival, which Georgian Revival is sometimes called.

Gingerbread style: A richly decorated American building fashion of the 19th century.

gingerbreading: Wooden architectural ornament popular with American folk houses in the late-19th and early 20th centuries, particularly in the Stick Style. Gingerbreading often took the form of scalloped or zig-zag-edged clapboards, which were often painted in contrasting colors. At times, gingerbreading could be superfluous and almost gaudy, with excessive frills and curlicues. The widespread use in the mid-19th century of the jigsaw – a hand tool consisting of a handle attached to a small, thin blade – made gingerbread decorations readily available to home builders.

Colonial hipped cottage: Colonial-style hipped roof cottages appeared before the end of the 19th century, but were especially popular during the first few decades of the 20th. The overall shape and plan were closely related to the generic cottage. There is historical continuity in the use of a square plan and the cubical shape, but the real essence of this colonial revival lay in the application of colonial motifs to the basic form. The entire design became formal and, for the most part, restrained. The roof took on a flat with a balustrade, while chimney caps were vaguely colonial or Queen Anne. The roof carried a central hipped dormer. The façade received slightly different treatments on each level, the first floor being a wide, plain wall pierced by large cottage windows, by a paneled door with molding plants derived from historic patterns, and occasionally by sidelights. The porch was distinctly classical: the porch posts were columns, and most often the porch treatment included an order of architecture complete with a short pediment over the porch steps. The second-floor windows did not align with the first. Windows were indented toward the center, which often displayed an oval window on the center line. In a few cases, a second-floor door replaced the oval window for access to a balcony

open-gable cottage: A cottage with a wide gable and plain form. It could just as well be called the flush-wall, center-axis cottage, because these features characterize its design, but that would be an awkward label. The open-gable was built for almost 50 years throughout most of the country. It has been a two-story house, though there were one-and-a-half story versions clad in brick, shingle, and clapboard, the last being the most prevalent. The open-gable cottage has clean lines, simple form, and no projections off the façade; it carries the façade wall up into the gable, with no distinction between façade and gable until the early 1890s. This house has a classical orientation, in that the façade is a linear temple front in which thin corner boards or pilasters carry a low, wide pediment. The introduction of cornice returns reinforces this impression. The façade is organized around a center axis running from the apex of the gable to the ground level. Able windows are placed on or along the side axis, and porches with three posts have the middle post placed on the same line. What detailing appears is often derived from bungalow or Craftsman designs.

bay-front rowhouse: The bay-front rowhouse was one of the last editions of this universal city house. Later 19th century and early 20th century builders looked for ways to address the narrow facade. Most frequently they extended the house by means of a porch replacing the traditional stoop, and compressed the upper level with a three-sided oriel window. There were other variations in the window treatment on the second floor, but most motifs involved replacing the sash windows with an alternative form

conch house: Natives of the West Indies – many immigrating to America to work in Florida’s cigar industry – brought the Conch house to Miami and Key West in the late 19th century. (Native Bahamians were colloquially called “Conchs” at that time.) This simple one- or two-story building form was raised on piers and featured a porch or two-story gallery, often decorated with gingerbread trim, to catch cool breezes. The earliest examples are said to have been crafted by ships’ carpenters using a cross-braced timber system based on shipbuilding techniques, but the vast majority are actually balloon frame structures sheathed with clapboards.

New American landscape: Late-20th c. style developed in America involving more sustainable, ecologically sound landscapes, and rejecting ‘passive vegetative architecture’ in favor of bold massing of perennials and wild grasses, responding to light, wind, and seasonal change: it was paralleled by New Perennials or Dutch Wave planting…

William McKinley, 1897-1901

American Foursquare: A two-story house style named for the square or block shape of the structure, with four rooms positioned over four rooms. One of the most popular styles from 1900-1930.

foursquare: The name given to the simple, square-shaped house built in profusion as middle-class housing between 1900 and 1930.

four-square: The name given to the simple, square-shaped house built in profusion as middle-class housing between 1900 and 1930.

Colonial gambrel cottage: The colonial gambrel cottage is a subtype of the generic model. Throughout most of its history, which includes authentic 18th-century examples as well as several revival-style types, the house has been thought of as Dutch in origin and spirit. The revival style was popular during 1900—1940 and was referred to as Dutch colonial. The shape of the building was strongly dictated by the shape of the roof, which in the Dutch-Flemish tradition frequently had flared eaves. In many models the flare was wide enough to provide some shelter over the entrance. The roof ridge ran parallel to the street, so that the facade was available for a full design treatment. A three-bay front was common, but five-bay units can be found. The second-floor level was outlined by either a long shed dormer that covered most of the roof, or by two or three evenly spaced gable dormers. The dormers were repeated on the rear elevation. The entrance was understated, with only a hood or a pediment to mark the door and the shallow porch. Some pediments evolved into porticoes with slender columns. Fenestration was for the most part symmetrical on all elevations…

Carrara glass panels: In 1900, the Marietta Manufacturing Company claimed to be the first producer of pigmented structural glass, rolling the first sheet of a “substitute for marble,” Sani Onyx. The company advertised “Sani-Onyx” as an easy-to-clean, germ-free surface.

band window: One of a horizontal series of three windows or more, separated only by mullions, that form a horizontal band across the facade of a building In the US, most commonly found in buildings erected after 1900.

catalog houses: After World War I, between 1900 and 1917, middle class society was expanding and, for the first time, beginning to buy more homes. To meet growth demand, companies started expanding in the residential building industry. Kit houses purchased through mail-order became popular in the 1910s, allowing new homeowners to be a part of the design and building process and giving the option of buying the home in stages.

Theodore Roosevelt, 1901-1909

kit houses: Between 1906 and 1940, thousands of North American homes in the United States and Canada were built according to plans sold by mail order companies such as Sears and Montgomery Ward.

Craftsman: A popular American style in the early 20th century exemplified by wide eaves, exposed rafter and beam ends, large porches, and the use of rustic materials.

Mission Revival style: A popular style in the early 20th century that made liberal use of elements seen in earlier Spanish/Mexican buildings; originally regional, the style spread nationwide by 1920.

Prairie School: An early 20th-century design that rejected historical and Classical styles in favor of open, flowing floor plans and a strongly horizontal character, suggesting, some say, the Midwestern prairie. Centered in Chicago, it is strongly associated with its boldest practitioner, Frank Lloyd Wright, although he worked beside several capable peers.

Centered in Chicago, it is strongly associated with its boldest practitioner, Frank Lloyd Wright, although he worked beside several capable peers.

Prairie: An architectural style characterized by its overall horizontal appearance (which is accomplished through the use of bands of casement windows, long terraces or balconies, flanking wings, low pitched roofs with wide overhangs, and darkly colored strips or bands on exterior walls).

Prairie House: A style of Midwestern architecture influenced by Japanese forms, invented by Frank Lloyd Wright (1867-1959). It later developed into the Usonian House style.

Usonian houses: A term used by American architect Frank Lloyd Wright to refer to his vision for the landscape of the United States, including the planning of cities and the architecture of buildings.

Twentieth Century Commercial style: In the early 1900s a new commercial style developed as a reaction to the ornate Victorian architectural styles of the late 19th century. This style became popular because of its adaptability to a variety of building types, especially the new one-story, flat roofed commercial building, which appeared in the City of Buffalo in the early 1900s. The character of the Early Twentieth Century Commercial buildings is determined by the use of patterned masonry wall surfaces, shaped parapets at the roofline that were often uninterrupted by a project cornice and large rectangular windows arranged in groups. The “Chicago window,” a three-part window with a wide, fixed central light flanked by two narrower double-hung sashes, is a common feature. Identifying features of this style include a plain, flat appearance that is relieved by the use of panels of brick laid in patterns and sparingly used inset accents of tile, concrete, limestone or terra cotta.

square house: This structure is a square or nearly square box with peaked-hip roof (sometimes truncated at the very top). Being two rooms wide and two rooms deep, it is essentially a 2- or 2 1/2—story version of the pyramidal cottage. However, most cube houses provide substantially greater floor space than pyramid cottages. This form type was popular throughout the first three decades of the 20th century.

movie theater: The movie theater took many shapes in the early years of the motion-picture industry. Early theaters were often shops or stores converted to the new use with little accommodation for the medium. As the motion picture became a significant force in American culture, the movie theater acquired architectural style.

IES: Illuminating Engineering Society, a professional society in North America devoted to the development and dissemination of standards and procedures relating to the art, science, and technology of lighting.

Munsell system: A widely used system for the designation and nomenclature of surface colors, developed by Albert F. Munsell of Boston, Massachusetts, and published as the Munsell Book of Color by Munsell Color Company, Baltimore, Maryland.

William Howard Taft, 1909-1913

rectilinear cottage: The rectilinear hipped cottage was especially popular in the plains states. In the decade following 1910 this square-looking version of the hipped cottage developed as an alternative to the Italianate and Queen Anne styles. Eschewing ornamental details, the rectilinear builder changed color at the upper level, changed materials, used trim boards or belt courses that framed the Walls into panels, and modified window placement. The rectilinear was a practical design that paralleled the development of the prairie-style design. The first floor of the rectilinear cottage contained social and service areas organized in an open plan, while the second floor had the usual array of bedrooms and a bath

Woodrow Wilson, 1913-1921

Zoning regulations: Legal restrictions which were intended in the first place to relieve street congestion by regulating the height of buildings. The New York Zoning Act of 1916, the first American act of the kind and the model for most later ones, determined the permissible height of walls next to the street by two factors, the type of district or zone and the width of the street. Additional stories above this had to be set back behind a line drawn from the center of the street through a point at the top of the front plane of the street wall, except that upon one quarter of the total lot area the building could rise to any height.

code: Legal restrictions of a given locality governing the building of various types of structure.

megalopolis: Very large urban region formed of a metropolis that has far outgrown itself and swallowed many towns and villages, or a series of metropolis that have joined up (e.g. the urban sprawl between Washington, DC and NYC).

Art Deco: An architectural style characterized by: an overall linear, angular, vertical appearance; stepped façade; extensive use of zig-zags, chevrons, lozenges, and volutes as decorative elements; and vertical projections above the roof line.

Warren Gamaliel Harding, 1921-1923
Calvin Coolidge, 1923-1929

Radburn: Planning principle developed at Radburn, New Jersey, on lines suggested originally by Ebeneezer Howard and promoted by Mumford, Clarence Stein, et al. The proposed town (which was later transmogrified as a commuter-suburb) was designed (1929) to segregate pedestrians and traffic by having cul-de-sac feeder-roads and paths on bridges or in underpasses. This principle of segregation, known as Radburn planning, was also used in various New Towns created in Britain and on the Content after the 1939-45 war.

Skidmore, Owings & Merrill: The world’s most successful firm of architects – see, in particular Fazlur Khan (1929-82).

California School: Term used to group some American landscape architects, all working independently, but responding to Californian demands for gardens with amenities such as swimming-pools and terraces allowing the living-rooms to extend outwards…

Harry S. Truman, 1945-1953

urban renewal: Fashionable 1950s American euphemism for large-scale destructive redevelopment, often in association with central or municipal government, offering rich pickings for commercial architects…

futuristic homes: While tradition held through the 1950s and 1960s, innovative designers were always looking for new expressions. As the space age unfolded, visions of the ultra-modern future captured the American imagination, sometimes inspiring house designs that would have looked more at home on other planets than on Earth. New building methods made virtually any structural feat possible, and bizarre shapes were no problem. Most fell by the wayside, but the geodesic dome, patented by Buckminster Fuller in 1954, caught on in the 190s, and by the next decade more than 80,000 sets of plans for dome homes had been sold.

Dwight David Eisenhower, 1953-1961
John Fitzgerald Kennedy, 1961-1963

theme-park: A 1960s term for a type of park devoted to a theme, idea, or ideas, which might have some historical, fictional, or other core. It was invented by the Disney organization at Anaheim, CA, where traditional American vernacular architecture and a main street of c. 1895 were recreated…

alternative architecture: Dwellings constructed with parts of motor-vehicles or other recycled material, sometimes based on geodesic principles, in the 1960s, especially in the USA. Some doubt if it is architecture.

Suppermannerism: American style of interior decoration dating from the 1960s employing odd optical tricks, synthetic materials that were either shiny and mirror-like, or transparent, and over-sized elements, so it was referred to as ‘mega-decoration’, and owed more to images in Superman comics than to Mannerism. 2. Term applied (1970s) to large Post-Modernist buildings.

Advocacy planning: Coined by the American planner Paul Davidoff, meaning architectural design and planning for powerless, inarticulate inner-city groups, notably when resisting destructive schemes by planning authorities, government agencies, etc. Among its early practitioners were ARCH (Architects; Renewal Committee in Harlem), founded by C. Richard Hatch.
