Rammed Earth Passivhaus

The first rammed earth certified passivhaus project in the world, this project overlooks a beautiful alpine lake on a site just ten minutes from downtown Coeur d'Alene, Idaho.  To realize the potential of dwelling in such a spectacular setting, the southern, lake-facing side of the home features entire walls of glass in the living room and the primary bedrooms.  

Owner Interview & Tour Video

This project is an excellent case study for the potential of the design freedom that is possible while still achieving exceptionally high performance construction. The interiors are flooded with natural light, dominated by the incredible scenery, and amazingly comfortable.
