This small backyard building in urban Bellingham was designed for multiple uses: yoga studio, brewery, workshop, and cycle storage. While not built to be a living space, it does have a bathroom. The entire project was built for just $120,000, with the client doing much of the finish work. With its south-facing roof, this building is ready to become net-zero-energy with the installation of solar panels.
