21. Treehouse
SHED
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.
• Compact 24’ x 30’ footprint on three levels used to create 1644 SF of living area
• Elemental material palette: GWB, cork, plywood, PLAM, tile
• Pragmatic/direct detailing for all building assemblies
The project pursued sustainable design solutions.
• Compact footprint reduces site impact, as well as material costs / long term energy use
• SIPS roof panels / BIBS insulation used to create a thermally efficient envelope
• Pre-installed Solar Thermal hot water tank, water lines and LV control wire
• Operable skylight passively cools/ventilates the house / reduces lighting requirements
• Heat recovery ventilation (HRV) system supplies all mechanical fresh air
• Hydronic radiators used for primary heating system
