Watershed Passive

West Templeton, CA

This project evolved over a number of years as the owner and Semmes developed the property. After completing a beautiful Corten barn,driveway and the off-grid equipment building the construction of the residence began.

The modern, low-lying home’s orientation works exceptionally well with the Passive Solar design while also providing expansive views over an inset swimming pool and the uninterrupted coastal forest of the large property. Watershed earthen-block walls provide structure and their mass balances the significant temperature swings that are unique to Central Coast region. 4 Zone Mini Split Heat and AC, Spray Foam Sealing and Blown-In Batt Insulation create a comfortable interior environment year-round. The softness of the natural light is contrasted by the prevalence of concrete throughout the home. It is paired with a variety of materials including wood, Corten, glass and stone in select areas to create texture and focus on the modern design of the residence. The rear terrace with covered outdoor chef’s kitchen champion family togetherness and effortless entertaining.

This home has has received both local and national recognition:
