About this home

In the storied enclave of Diablo, where privacy and prestige quietly define the landscape, this masterfully crafted estate presents a rare opportunity to own a home of substance and serenity. Classic Craftsman architecture gives way to soaring interiors filled with natural light and framed garden vistas. Rich wood floors run throughout, grounding the home in warmth and refinement. Dual fireplaces anchor the living and family rooms, while expansive decks blur the line between indoors and out. At the center, a statement kitchen pairs sculptural quartzite with professional-grade Miele appliances — equally suited for intimate dinners or elegant entertaining. The primary suite is designed as a private retreat: heated floors, a spa-caliber wet room bath, and an expansive custom wardrobe evoke the feeling of a five-star resort. A secondary ensuite, two additional bedrooms, and a dedicated pool bath ensure both flexibility and thoughtful design. Outdoors, the estate unfolds into a resort-like
