high tech
More an attitude than a style, high tech emerged in the 1970s in the work of such architects as Norman Foster, Richard Rogers, and Renzo Piano. High-tech buildings tend to be steel, emphasize lightweight structure and structural connections, often have long spans, and incorporate new building materials and techniques. Although these buildings feature structure, they are not simply exposed construction. The British engineer Frank Newby once sarcastically defined high tech as “the use of redundant structure for decorative purposes.” (Rybczynski, 2013)
