Spatio-visual patterns in architecture: an analysis of living rooms in Frank Lloyd Wright houses

It has been alleged that living spaces in the domestic architecture of Frank Lloyd Wright feature a distinct pattern of spatial and formal features which elicit positive emotional responses from visitors. Researchers have argued that the source of this appeal is found in the unique balance Wright achieved between outlook, enclosure and mystery. While this explanation is apparently accepted, little quantitative evidence exists to confirm that these houses actually contain the type of spatio-visual properties required to provoke such similar experiences. This paper utilises isovist analysis to seek mathematical evidence of patterns in the prospect, refuge and mystery related characteristics of 17 of Wright’s most famous houses. This analysis reveals an unexpectedly high degree of similarity between the designs, which is slightly less pronounced when exterior views are included.
