Architectural Designation - Sonoma Hilltop Modern Contemporary Residence is designated as KeyPrice Signature Architecture in recognition of its exceptional reinterpretation of California Mid-Century Modern architecture, extraordinary integration with the Sonoma landscape, and its refined expression of indoor-outdoor living. Designed by the acclaimed Klopf Architecture, the residence elevates the principles popularised by Joseph Eichler into a contemporary luxury estate, where restrained architectural language, natural materials and panoramic views combine to create one of Sonoma Valley's defining modern homes. Positioned atop more than sixteen acres overlooking the San Francisco Bay, the residence demonstrates how modern architecture can celebrate both simplicity and spectacle without compromising either.

Completed in 2022, the approximately 4,080-square-foot residence unfolds as a series of linear volumes carefully embedded into the ridgeline, allowing nearly every principal room to engage directly with the surrounding landscape. Warm stained cedar cladding presents a quiet, understated façade to the arrival court before opening dramatically toward the valley through retractable floor-to-ceiling glazing. Deep roof overhangs, exposed structural beams and crisp horizontal lines pay homage to classic Mid-Century Modern design, while premium contemporary detailing—including Calacatta marble, white oak flooring, bespoke lighting, luxury appliance integration and a vanishing-edge swimming pool—redefine the typology for the twenty-first century. Rather than dominating its environment, the architecture becomes an extension of the rolling vineyards, oak forests and distant mountain ranges that define California's celebrated wine country.
