- Passive House Plus Certified - LEED Platinum Certified
Located on a steep slope in San Francisco’s Castro neighborhood, this modern, high performance home is closely knit into the landscape and neighborhood while also setting ambitious goals for energy and resource conservation. The interior spaces of the existing home have been completely redesigned to offer the best views of the distant landscape while also fostering a close connection to the immediate landscape: the hillside and cherry tree behind the existing home. The clients, with their growing family, also sought a modern design that would grow with them and give them the flexibility to adapt their space. With that in mind, 450 Architects integrated a guest studio unit within the home that can operate independently, and a sliding wall which offers the ongoing choice to create an additional bedroom or expand the living room. Engineers and graduates of MIT, the clients also set the ambitious goal of converting their 50’s era tract home into a net zero home. With the intent to maximize water and energy conservation, design strategies include natural building materials, composting toilets, greywater systems, and photovoltaic solar power to meet and exceed benchmarks set by LEED Platinum, Passive House, and Greenpoint rating systems.
