What our Clients are Saying

“My kitchen looks lovely, thank you for the professional job.”

Esther McEvoy, Corvallis

“Carl’s house avoids 19 tons of CO2 every year compared to a code house. If all houses throughout the entire United States did that, it is possible to slow down carbon emissions to the point that we can slow down global warming and eventually, hopefully, reverse it.”

Jan Fillinger, Architect

See the Craftsman Custom Passive House project

“Carl came up with a few different designs to shade the front windows from sun during the summer. The designs were done with software that could show the amount of shading and view from different angles, including from inside the house, at different times of the year. This was very helpful in visualizing the designs and making decisions.”

Brian Lee, Corvallis
