The house is a study in the honest use of materials, particularly structural materials. The exposed wood-and-steel trusses are common in commercial architecture but rare in houses, and are almost never left exposed. Here they are celebrated.
 
Even more unusual, the windows are installed outside of the wall, rather than within the wall. The wood studs are then left exposed at the windows, where they appear to be mullions. Because none of the studs were cut to insert windows, no headers were required, so the windows go right up to the ceiling.
 
This was especially important given the narrow site, where high windows allow a view of the sky and tree canopies without sacrificing privacy.
