Green Hammer

About us

Green Hammer is a Portland, Oregon-based full-service design-build firm, founded in 2002, that specializes in healthy, eco-friendly renovations of existing homes as well as new construction, with particular expertise in Net Zero Energy and Passive House design, certified Living Buildings, and LEED Platinum-rated homes. The company is a Certified B Corporation and has been named a 'Best of the World' B Corp Honoree — a recognition reserved for companies scoring in the top percentile of all B Corps globally on B Lab's Impact Assessment — in addition to being named one of Oregon's Most Admired Companies and one of Oregon's Best Green Workplaces.

Green Hammer's stated specialty is 'deep green' home renovation: taking on whole-house remodels of existing housing stock and bringing them up to rigorous, third-party-verified performance standards (Passive House and Net Zero Energy) rather than incremental efficiency upgrades alone. The firm's own recognition history includes induction into the Earth Advantage Builder of the Year Hall of Fame, reflecting sustained, multi-year performance in the Pacific Northwest green-building sector rather than a single award. The company operates out of Portland and also serves the Ashland, Oregon area.

Green Hammer maintains a LinkedIn company page and a Facebook profile, and publishes its formal B Corp mission, purpose, and values on its site.
