Cascade Built
Transforming Seattle's built environment with high performance, Passive House multi-family buildings that require little energy for space heating and cooling and set a foundation for achieving a Net Zero building. Passive House buildings also last longer with 100-year building envelopes and meet rising demand for healthier homes with fresh, filtered indoor air.

Cutting-edge mixed-use buildings that use up to 90 percent less energy for heating and cooling, while maintaining comfort from the region's preeminent Passive House builder. A proven approach, durable materials, and a passion for constructing buildings that are better for its residents, owners, the community and the environment.

Sloan Ritchie developed a practice around science-based building that meets compelling demand for energy efficiency and a significant reduction in global greenhouse gas emissions. For nearly two decades, his commitment to deconstructing the idea that there's only one way to build has led him to explore and deliver a proven path of high-performance construction and buildings that developers want and consumers are beginning to demand.

Positive: Professionalism, Punctuality, Responsiveness
We have worked with Cascade Built on multiple multi-family buildings and Cascade Built is one of the most organized contractors that I know. They know how to bring a job in on time, on budget, and with quality in mind. I can't recommend them enough.

Report
I bought and lived in a Cascade Built townhouse and had horrible issues with the plumbing and HVAC, which was installed incorrectly and had to be replaced in my and the other unit for a cost of $8,000.00 each. Talk about unsustainable construction. More like green washed. Cascade Built did not stand by their construction. Also, the other reviews here are from the owner's wife, Jen Ritchie who is in PR, and "wiz KID", who is the owner Sloan Richtie.

I live in a Passive House built by Cascade Built and it's unbelievably comfortable and quiet. Innovative, thoughtful, high quality and high performance.
