The Gustavson Residence – A High Performance Prairie ranch

This infill project, located on a small suburban lot, required a limited 1st floor footprint for aging in place, while still providing plenty of room for their growing family. A gently sloping landscape allowed us to place all the main living space on the first floor, including the master suite. All the children’s bedrooms are located on the lower level, with abundant light through egress windows.

The “Prairie” styling of architect Chris Manske perfectly complemented our “High Performance” home requirements. This includes long overhangs for summer shading as well as open interior space to reflect natural light and absorb the winter sun into the acid stained concrete floors.

Our biggest challenge was to develop a system to fasten the natural “Halquist Maple Ridge” stone veneer to the 6” polystyrene foundation insulation. Yes, there is 6” of foam behind that stone! Above grade, the walls are 8” Structural Insulated Panels with Icynene spray foam insulation used in the box sills and as part of our hybrid roof insulation. High efficiency triple pane fiberglass windows were the final ingredients in this super-insulated structure. It achieves a very low 359 cfm @ 50pascal blower door test.
