A celebrated tastemaker with an unmatched eye for design, Diane Keaton spent decades transforming homes into works of art, blending timeless architecture with warmth, authenticity, and soul. This extraordinary residence represents the culmination of that passion a Napa-inspired estate that embodies everything she loved most about residential design. Located on prestigious Riviera Ranch Road within Sullivan Canyon's celebrated celebrity enclave, the estate is privately situated on an approximately 28,000-square-foot lot and spans more than 9,000 square feet of living space. Defined by soaring ceilings, abundant natural light, reclaimed architectural elements, and a level of craftsmanship rarely seen today, every room has been thoughtfully curated to create an atmosphere that feels both grand and remarkably inviting. The home showcases a collection of reclaimed light fixtures, rich natural materials, and architectural details that evoke the character of a refined wine-country retreat while remaining perfectly suited to Los Angeles living. Expansive public rooms flow effortlessly to the outdoors, creating an ideal setting for both intimate gatherings and large-scale entertaining. A separate guest house provides exceptional flexibility for visitors, extended family, staff, or a private office and creative workspace. Approached through double gates and a dramatic motor court driveway, the property offers a sense of arrival typically reserved for the finest estates. Surrounded by mature landscaping and positioned far from the street, the estate delivers an exceptional level of privacy and ultra-high security, making it one of the most secluded residential offerings on the Westside. The setting feels worlds away from Los Angeles while remaining just minutes from the city's premier amenities. Long prized for its unique blend of privacy, natural beauty, and equestrian heritage, Sullivan Canyon is home to one of Los Angeles' most sought-after horse communities. Nearby riding trails, boarding facilities, and equestrian amenities offer a lifestyle rarely found within the city limits, providing residents with the opportunity to enjoy country living in the heart of a world-class city. Rarely does a home become available that so perfectly reflects the vision of its creator. Much like the celebrated homes she restored throughout her life, this residence balances history, craftsmanship, and modern comfort in a way that only Diane Keaton could envision. This is more than a residence; it is the final architectural statement of a true design icon.
