About This Home

855 Grapestone Lane

Set on two acres amid the vineyards of Sonoma Valley, 855 Grape Stone Lane is a contemporary Wine Country estate featuring a single-level main residence and detached guest house totaling 3,313 square feet, plus a resort-like pool and spa - all just minutes from the historic Sonoma Plaza. Clean architectural lines, a warm neutral palette and expansive indoor-outdoor living spaces create a relaxed, refined setting for both everyday living and entertaining. The open-concept great room brings together the living, dining and kitchen areas, while a luxurious primary suite and additional en suite bedroom offer privacy and comfort. The guest house provides flexible accommodations for visitors, a private office or creative studio. Outdoors, generous patios, mature olive trees and 1.5 acres of dry-farmed, old-vine Zinfandel frame the pool, Baja shelf and spa, creating an inviting setting for gathering and relaxation. Gated entry, radiant floor heating, solar, a private well, natural gas, a four-bedroom septic system and CALGreen certification complete this thoughtfully designed Sonoma retreat.
