I Cottage
A 1- or 1 1/2-story version of the I house, this structure is one room deep and two rooms wide with a central hallway. Gabled roofs predominate. End chimneys are prevalent in nineteenth-century cottages (a). I cottages are commonly enlarged with rear extensions which gave them an overall L or T shape (b).
