Frank Lloyd Wright house
This is a wonderful illustration of Frank Lloyd Wright's Suntop Homes, which he called the "Ardmore experiment." The structure included four housing units and is still standing in Ardmore, Pennsylvania. Four of the units were to be built in Ardmore, but only the one was ever constructed. More photos of the dwelling are available here. This site has background on Suntop Homes. 1939
Invented by Frank Lloyd Wright
