How We Brought This Project to Life

Respecting the Past, Planning for the Future

Every detail, historically mindful.

The deteriorated rear addition was rebuilt to match the original style, while all new work adhered to Napa’s historic preservation guidelines—no commission revisions required.

Strengthening the Structure

Modern safety behind classic walls.

Balloon framing gave way to new engineered walls with fire-blocking and seismic reinforcements. Foundation anchors were added to resolve settling and prevent moisture intrusion.

Upgrading the Core Systems

New plumbing, power, and comfort throughout.

We replaced old galvanized and cast iron lines with copper and PEX, upgraded electrical to 200 amps, and installed a high-efficiency zoned HVAC system. Spray foam and rigid insulation ensured year-round energy performance.
