This West Seattle House Gets a 'Tree House' Addition




Project Name: West Seattle Tree House Addition
Location: West Seattle
Professional: Motionspace Architecture + Design PLLC, Malsam Tsang Structural Engineers and Niederberger Contracting
Timeframe: 2011 to 2013
Cost: Approximately $250K
Description: The clients expressed a desire to construct a new second story with a master suite to capitalize on the amazing view. The site had its own challenges, being on a steep slope, which limited the possible area of development, and a high wind zone, which made modifications to the existing structure more challenging. After examining their options and consulting with their structural engineers, Motionspace decided to construct the new addition mostly over an existing very solidly built 'bunker garage'. The new addition added two levels of covered decks which greatly increased outdoor living space facing the amazing view. And at the top the master bedroom faces the view while being nestled next to an existing pine tree, giving the feeling of being in a tree house.
