A naturally cooled room is tucked into the hillside of this timeless, sophisticated architect’s home, creating an immediate sense of a private wine cave. Thick surrounding soil and concrete help stabilize temperature, making it an appealing candidate for wine storage or small lot production. The space feels substantial and functional, while still feeling intimate and protected. Access and its separation from the main living areas enhance its potential as a dedicated wine cellar or artisan winemaking room, where barrels, and bottles can live without impacting the rest of the home. Originally built in 1973 by Architect Robert Gianelli as his primary residence in Alta Heights-integrates dwelling with landscape. Expansive use of glass, and wood, showcases the natural light of the Napa landscape, with sweeping southeast views of the rolling hills and distant sun-drenched vineyards. Flowing effortlessly from room to room for modern living and endless entertaining this home was masterfully remodeled between 2021 and 2025 by the current/2nd owner. The renovation expertly preserves the original mid-century/modernist style while incorporating contemporary luxury amenities. Four bedrooms and four bathrooms, with every bedroom opening to a private deck or patio. The fourth bedroom offers a unique advantage: an attached studio, with its own exterior entrance, ideal for a home office, professional consultation space or wellness room.
