Cascadia Green Building Council, in partnership with the Aleutian Housing Authority, invited the world’s most talented and daring architects and engineers to design an affordable, single-family residence in one of the world’s most challenging environments: Alaska’s Aleutian Islands to meet the Living Building ChallengeTM. The winning entry will provide a prototype design for the housing Authority to use throughout the Aluetian Islands.

Collaborating with Brute Force Collaborative, the off-grid 3-bedroom, 1-bath house is powered by a 1.5kW turbine.

The home incorporates compact massing with a high performance envelope to achieve a high level of comfort and efficiency in an extreme environment. The cross laminated timber structure is harvested from pine beetle-infected wood from British Columbia. The house also features a wintergarden, rainwater harvesting system, greywater system, living wall, and a composting toilet. The entire project is flat packed to the site and built by hand out of the container to site meeting ‘The Challage’.
