TARTAN ROAD, MILL VALLEY

Located in the Tartan Road area of Mill Valley, this 3,800-square-foot split-level home sits on a challenging hillside site. The build required a carefully engineered foundation system to support both the structure and surrounding terrain. The foundation combines soil nailing with reinforced retaining walls. Piers and grade beams provide additional support and ensure proper load distribution across the slope.

The layout steps with the hillside to integrate the structure into the site. At the same time, it maintains a clear and functional interior flow. The home includes three bedrooms and 3.5 bathrooms. Vaulted ceilings introduce volume and require coordinated structural framing.

An open-plan kitchen, dining, and living area forms the central living space. This layout supports clear spans and strong connectivity between rooms. The building envelope incorporates exterior siding systems along with large-format windows and doors. These elements required precise detailing to address weatherproofing, thermal performance, and structural openings.

At the same time, the design supports indoor-outdoor connectivity without compromising performance. Overall, the project reflects a balanced approach between structural engineering and architectural intent. It delivers a home that responds directly to site conditions while maintaining a clean and functional design.
