The Salmon Bay Passive House began with the owners’ vision for a resilient, low-carbon home that prioritized energy efficiency without compromising comfort or the joy of entertaining. This urban setting offers sweeping views of a historic Seattle park to the south—an orientation that informed a design focused on expansive glazing for both visual connection and optimized solar gain in the region’s heating-dominated climate.
The main living space is conceived as an open, social heart of the home, anchored by a chef’s kitchen and generous dining area, with seamless connection to a west-facing courtyard that extends living outdoors. A restrained palette of natural materials—wood, Corten steel, and Richlite panels—was selected for their tactile quality, environmental integrity, and ability to weather gracefully with minimal maintenance. One of the home’s most defining architectural elements is its Cross Laminated Timber (CLT) roof structure, which serves as both structure and finish—spanning to create deep cantilevers that act as a solar parasol, precisely tuned for passive solar performance while celebrating the warmth and honesty of exposed timber.
