With an eye toward creating a sustainable future for a young family of four, the design for this home focuses on integrating ecological building strategies, super energy efficiency and an accessible open floor plan that is flexible enough to adapt to the family’s changing needs. The house is situated on a sunny south facing site, with glimpses through the native oaks of the local creek canyon below. The house opens to the south and sits close to grade minimizing the inside-outside transition. Covered terraces and porches provide the appropriate solar shading and expand the living area for the modest house during the many seasonable Northern California months.
Inspired by natural building materials and raw industrial loft spaces, the owners wanted to create an aesthetic that both celebrates the “imperfect” qualities of handmade structures and that also has a clean contemporary feel. A weathering steel metal roof, native log post details, polish concrete floors, salvaged wood, and locally sourced materials and products are used to underscore the aesthetic and ecological goals.
The simple form and massing of the house allow for a cost effective high performance building envelope to be created. Using wood framed construction keeps the project budget conscious: advanced framing techniques, thermal free bridge construction details and thoughtful structural engineering minimize wood usage and expense.
A combination of passive solar design, meticulous air sealing, high performance windows, and attentive insulation details reduce the space conditioning requirements of this house to a mere fraction of a typical home. With a recently added 7 kw photovoltaic array, the all-electric house is a net zero energy building. A single ductless mini split provides the primary heating and cooling for the house is able to keep the house at a comfortable temperature during the hottest and coolest days of the year. The HRV (mechanical ventilation system) and passive radon-mitigation systems insure the house has good indoor air quality and is a healthy house to live in.
