What We Build
Winery & Estate Construction for Napa Valley
Tasting rooms, estate homes, and fire-hardened structures for wine country's most demanding sites — built to outlast the next fire season.
The Approach
San Francisco precision, planted in wine country.
Mavericks Builders is a Bay Area general contractor by origin — the firm that helped develop the USGBC LEED for Homes program. That urban-modern discipline is exactly what Napa Valley's most ambitious estates require: tight tolerances, sophisticated detailing, and structures engineered to perform, not just to charm.
Thirty years in, Robin Nielsen pairs that precision with deep agricultural-land fluency — ag overlays, slope and access, wells and septic, the realities of building on working vineyard ground. The result is wine-country construction without the rustic compromise.
Section 01 — What We Build
A full program for the estate property.
Estate Homes
Architecturally driven primary residences built to bespoke tolerances — the centerpiece of the property, engineered for the site and the climate.
Tasting Rooms & Hospitality
Guest-facing spaces where brand and architecture meet — tasting rooms, hospitality pavilions, and entertaining structures detailed to impress.
Production & Barrel Buildings
Functional winery infrastructure — production facilities and barrel storage built for thermal performance, durability, and daily working use.
Guest Houses & ADUs
Secondary residences and accessory dwelling units that extend the estate — designed and permitted within ag-overlay and zoning constraints.
Fire-Hardened Rebuilds
Rebuilding after loss, to standards that outlast the next fire. Class A assemblies, ember-resistant detailing, defensible-space-ready sites.
Outdoor Living & Event Spaces
Decks, terraces, pavilions, and event grounds — the indoor-outdoor architecture wine-country entertaining demands, built to last.
Section 02 — Rebuilding After the Fires
Build so the next one won't take yours.
The 2020 Glass Fire was the most destructive in Napa Valley history — 67,484 acres and 1,555 structures lost, taking estates, wineries, and landmark properties with it. For wine country, fire is not an abstraction. It is a recurring event the landscape is shaped by.
Robin and her team build for that reality. Every estate and winery structure is hardened against ember intrusion and fire spread from the ground up — so when the next fire season comes, yours is the property still standing. See our fire-resistant construction approach.
Section 03 — Agricultural & Site Expertise
Building on working land is its own discipline.
- Ag overlay & zoning — navigating agricultural-preserve overlays, use permits, and Napa County zoning before the first footing is poured.
- Well & septic — water supply, on-site wastewater, and the engineering that off-grid and rural parcels require.
- Slope & access — hillside grading, retaining, and access roads built for construction loads and emergency response alike.
- Defensible space — Zone 0–2 planning integrated into the site design, not bolted on after the fact.
- Sustainable & green systems — high-performance envelopes, solar, water management, and the green building expertise behind SF's USGBC LEED for Homes demonstration home.
- Whole-site coordination — estate home, winery, guest houses, and outdoor spaces planned as one integrated program.
Section 04 — Why Robin
No competitor brings San Francisco build precision, three decades of green building, and hard-won wine-country fire expertise to the same estate.
Robin has watched these fires reshape Napa Valley for thirty years — and they build the estates engineered to be the ones still standing when the smoke clears.
