Charles Sink raised this glassy house a story above street level to capitalize on the view of Washington Park and the Rockies beyond. One of the few conventional elements is the gable roof, with a prominent single chimney ending in the same slope to emphasize the angle. The house has a glass skylight, glass block, ceramic tile, and mirrors to add to the illusion of space. The architect-owner studied with Walter Gropius at Harvard and began his career working for I. M. Pei on Pei's Denver projects. Sink's other designs include One Cheesman Place (1968), East 13th Avenue and Williams Street, a twenty-story luxury apartment building with a structure entirely of post-tensioned reinforced concrete and views south over Cheesman Park through floor-to-ceiling glass.
