Treehouse is a single family residence built on an inaccessible, steep slope lot. The project had three primary design objectives: 1) minimize long term site impacts; 2) design a cost effective and resource efficient building; 3) use view, light and enclosure to accentuate the experience of living in the tree canopy.
Design Solutions and Features:
Budget drove design decisions.
