To an architect, a floor plan is like a musical score -- all the information is there if you know what to look for, and how to read it.
Frank Lloyd Wright's floor plans were incredibly nuanced, and deceptively complex. The example shown here is from the 1939 Rosenbuam House, one of Wright's forty-odd moderate cost 'Usonian Houses' -- just 143 sqm, but with the soul of a larger house packed in there.
See if you can identify some of the 'tricks' he's used to make the small house appear much larger. Can you spot three of them?
