Healdsburg Design Studio
Guest Houses That Feel Like
They've Always Been There
Thoughtfully designed guest houses, ADUs, and estate expansions for Healdsburg and wine-country legacy properties.
Built to Belong
Your estate has character. A relationship between architecture and landscape that took years—sometimes generations—to establish.
Adding a guest house or expanding your home shouldn't disrupt that. Licensed architects and builders coordinate designs that honor your property's legacy while creating functional, valuable space that feels inevitable.
The Challenge
Most Additions Look Like Additions
Generic contractors approach every property the same way. Pre-fabricated designs. Materials that don't match. Additions that feel tacked on.
For estates valued at $5M–$15M+, that approach risks long-term property value and disrupts the architectural integrity you've worked to preserve.
"We needed a guest house that felt like part of the original 1920s estate—not a backyard cottage."
— Estate owner, Healdsburg
Our Approach
Architectural Sensitivity Meets Deep Local Knowledge
Licensed architects and builders who specialize in wine-country estates study your property's existing architecture, materials, and landscape relationships before proposing any design.
The result: guest houses, ADUs, and expansions that look and feel like they were part of the original vision. Additions that enhance value rather than compromise it.
- Site-specific design coordination
- Material matching and sourcing
- Zoning expertise for high-value properties
