This vacation home designed to be “net-zero” lies in a historic mining area in Washington State’s Cascade Mountains. The climate is extremely cold and snowy in the winter months and scorching in the summer. Situated in a master-planned resort community, the house blends sustainable modern architecture with reclaimed rustic materials. Repeat clients Ed and Joanne Ellis first hired Coates Design Architects for their home and primary residence on Bainbridge Island – for the first LEED Platinum residence in Washington. They worked again with Coates Design who brought the same modern and sustainable design sensibilities to this vacation home intended to be a legacy piece for their extended family.
The extreme weather conditions challenged the design team to create a comfortable environment without use of traditional energy consumptive cooling and heating systems. The team sited the building to take advantage of passive solar strategies and created an abundance of sloped roof to support 10kWh PV Solar Panel array. This self-contained room serves double duty as a special place to welcome visitors and an air lock to keep the outdoor elements contained. Wintertime’s chilly drafts and summer’s excessive heat are kept at a bay with this simple solution. Dramatic cantilevered roof planes utilize passive solar strategies by barring the summer sun & heat yet inviting in the winter sunshine. These broad overhangs also create covered outdoor space, much coveted in this climate, and a sheltered entry experience.
Vaulted ceilings in the main living and dining area are supported by exposed steel and wood structural elements, and floor-to-ceiling windows look out on the landscape beyond. A large board formed concrete chimney commands attention as the focal point of the main living area. This solid mass, along with areas of concrete floor, serves also as a thermal heat sink to help maintain a stable and comfortable temperature inside. There are two primary bedroom suites and a bunk room in the main house to accommodate family members. A separate bunk house has space for recreation and an additional bedroom suite.
