Residential Additions
Estate Expansions That Feel Inevitable
Seamless additions that enhance livability without disrupting architectural integrity for Healdsburg and wine-country legacy properties.
Schedule ConsultationAdditions That Appear Original
Most home additions look like additions—mismatched materials, awkward transitions, and proportions that feel tacked on.
For wine-country estates valued in the millions, this approach compromises architectural integrity and long-term property value.
We specialize in expansions that integrate so seamlessly they appear to have been part of the original architectural vision—careful material matching, proportion studies, and transitions that feel natural.

The difference between a good addition and a great one is in the details—material transitions, roofline continuity, and proportional relationships.

- Roofline ContinuityMatching pitches, overhangs, and eave details for architectural coherence
- Proportional BalanceAddition scale and massing that respects the original structure

Home Addition FAQs
How do you match materials on older wine-country homes?
We source specialty materials and work with craftspeople who can replicate period-specific siding, trim, and roofing to ensure seamless integration with established architecture.
Will a home addition affect my property value?
When executed properly with architectural integrity, additions enhance property value by adding functional square footage while preserving the home character. Poorly executed additions can diminish value.
How long does a master suite addition take?
Most master suite additions take 6–10 months including design, permitting (2–4 months), and construction, depending on complexity and site conditions.
Can you expand a home on a hillside property?
Yes. We specialize in hillside expansions in wine country, coordinating structural engineering, foundation work, and grading to work with natural terrain.
