A magnificent transformation has redefined this 1929 French chateau into a modern estate of extraordinary light and sophistication. Once known for its European formality and ornate detail, the home has been renewed from top to bottom with the highest level of design, cabinetry, and finishes. Original millwork and moldings were meticulously preserved, now presented in a palette of light tones that elevate rather than overshadow the architecture. Exceptional lighting and carefully curated finishes bring contemporary elegance to every room, creating a residence that feels entirely new while honoring its historic character. The result is a home that stands among the finest expressions of luxury living today. Equally compelling are the dual-gated five acres of formal grounds that frame the estate. Vast lawns, parterre gardens, and farm-to-table gardens accompany resort amenities of a pool, spa, and tennis court, with multiple terraces providing an unparalleled setting for entertaining or private retreat. All of this unfolds within easy reach of Silicon Valley and San Francisco, establishing a rare estate property where history and modern vision meet at the highest level. among the finest expressions of luxury living today.
