Designed by Jerome Buttrick and built in 2005, this striking modern home blends clean architectural lines with a strong commitment to sustainability. Located in sought-after Old Palo Alto, it is a rare fusion of refined design and high-performance living. Radiant heated concrete slab floors throughout, solar power, a standing seam metal roof, and FSC-certified framing are among its many eco-conscious features. Interior finishes include paper-resin counters, low-VOC materials, and cherry cabinetry crafted from sustainably harvested wood. Energy Star appliances, efficient windows, low-voltage lighting, and an indirect hot water heater further enhance efficiency. The floor plan is designed with many glass doors opening to a gated front courtyard anchored by a heritage valley oak or to the beautiful rear yard with large spa. A main-level den and adjoining bedroom suite is ideal for guests and the primary suite is upstairs complete with an outdoor shower room plus one bedroom customized for a remote work office. Just one mile from University Avenue and access to acclaimed Palo Alto schools.
