After more than a year in progress, our Passive House retrofit project in Sonoma is finally complete.

Isn't she a beauty?

Homeowner Cathy O'Neill is in love with her new modern farmhouse (and so are the neighbors, now that all of the trucks are out of the way!) It's been an incredible effort and now so satisfying to see California's first Passive House and the country's first Passive House retrofit finally come to fruition.  We couldn't be more proud.
