Hammer & Hand: Passive House Builders in Portland and Seattle
As passive house builders we collaborate with clients and architects to create buildings of beauty, durability, comfort, and performance.
We believe in building better.
Our systems-based understanding of how buildings function enables us to deliver projects that boast both unmatched resilience and revolutionary energy efficiency.
Our advanced modeling tools coupled with our in-the-dirt practical experience allow us to give architects and clients more freedom to make the aesthetic and programmatic design decisions they need without compromising the performance of passive houses.
Ready to reduce your carbon footprint? Our Portland and Seattle teams are ready to help.
Passive House buildings, both residential and commercial, reduce heating and cooling energy consumption by 80-90% compared to conventional structures. Super-insulated walls hold warmth in the winter and cool in the summer while a continuous supply of fresh air ensures unparalleled indoor air quality.

Best Practices Manual
Our Best Practices Manual is the product of our ongoing work to document and internally codify our standard operating procedures. It has evolved into a guidebook of field-tested construction details, many shaped by our experience in high performance passive building.
We have made this information open-source in the spirit of collaboration.
