Leavenworth House 04

Project Notes

A fun mountain modern home in a small neighborhood of Leavenworth.  

Leavenworth, WA
Complete in fall of 2014

This house is a unique collaboration between the owners, previous residents of the Wenatchee Valley moving back to the area, and myself, a Leavenworth native and the structual engineer: a wannabe Leavenworth Resident.  Divergent paths in life collided in Seattle into what has formed a unique undertaking.  The house, to be constructed by the owner, will be a model of budget, efficiency and a Northwest design aesthetic fitting to the climate and flavor of North Central Washington.  Using ICF (insulated concrete form) blocks with an R-value of 25.5 the foundation on upward will be a model of where thermal design ought to go.  Minimum R-33 walls utilizing both blow in blanket insulation systems coupled with exterior rigid foam applications below native wood siding, the envelope of this house acts as jacket primary: capped with an R-58 SIPS roof and glazed with triple pane U.14 glazing.  Summer solar heat gain is mitigated by exterior eaves, and a large exterior shading device for the double height living room space.  Winter Solar Gain is achieved by the elimination of the shading device. At roughly 2100 SF, the house will act as work shop, studio, and family home.
