The Y House is situated on a hilltop from Y HOUSE. Designed by Steven Holl architects, the house has two arms, just like the letter from its name, that end in two balconies. The Y form is proper to bring the sun light right in the middle of the house.

The geometry contains a sectional flip of public and private but also for day and night, with bedrooms below and living above. Maximum wall hanging space to accommodate a contemporary art collection is balanced with windows framing unique views. Deep balconies facing nearly due south act as passive solar devices allowing the winter sun to penetrate the interiors while excluding the hot summer sun. Steel framing and roof are iron-oxide red, siding is stained cedar while interiors are white with ash floors.
