Whidbey Puzzle Prefab seamlessly merges high-performance sustainable design with endless customization and replication. Puzzle prefab is a carbon-negative prefab prototype organized around 4 modules for living, sleep/study, energy, and outdoor dining. The modules are built on pin foundations, eliminating concrete and reducing CO2 emissions by 24 tons. A 4.1 kw solar array drives a heat pump with hydronic heating and cooling and energy recovery ventilation. Smart home controls monitor energy use and optimize conditioning to align with user comfort.

The architecture minimizes its footprint, sources local materials, is built off-site, and incorporates impermanent foundations – reducing the physical and visible impact on the project location. This is a pilot project for the design team, which is tracking performance metrics, ensuring that each subsequent iteration will be informed by the lessons of the previous home. It succeeded in building something replicable and flexible, net zero, and low-impact to the project site, to creative a positive relationship between the build process, the environment and the inhabitants for generations.
