This prefab family house in Seattle was built from 67 CLT (Cross-Laminated Timber) panels made from 20 trees acquired from FSC-certified sources. Referencing a small Pacific Northwest beach cabin, the architects at atelierjones designed the house with a blackened wood exterior that strikes contrast with a whitewashed daylit interior. The project is one of the first in the US to utilize CLT as both a structural and a cladding material.
Located on a small triangular lot in Seattle, this house for a family of four aims to balance out the influences of the oversized alley and rear bank parking lot, and a neighborhood near Lake Washington. In order to manage the spatially dynamic nature of the immediate surroundings, the architects screened some of the views while leaving others exposed. A central service core channels utilities from basement to roof deck and is enveloped in glossy white and ice-blue finishes -plastic laminate, stainless steel and quartz. The core is surrounded by vertically lit spaces.
The CLT panels were prefabricated and routed using CNC technology and transported to the site, where the house was erected in only 12 days. Burnt shou-sugi-ban treated Douglas Fir covers the exterior walls. As a sustainable alternative to concrete and steel, CLT panels made from FSC-harvested regional timber promote mass timber as a viable building solution. Approximately 20 trees were used for the construction of the CLTHouse and then the owner’s family planted an additional 20 trees for carbon sequestration.
