Timeless Resort Estate | Premier Rancho Santa Fe Location Originally built in 2006 by renowned Sylvester Homes, this single-level Tuscan-inspired estate spans nearly 13,000 sq ft on 2 flat, ultra-private acres at the end of a quiet cul-de-sac. Recently refreshed with custom interior upgrades and modern designer lighting, the home blends timeless craftsmanship with a clean, updated aesthetic—making it one of the premier entertainer’s properties on the Rancho Santa Fe market. The flexible floor plan offers 4 bedrooms in the main residence plus a detached guest villa with separate living room and bedroom. Grand-scale interiors include a stunning great room with 23-foot ceilings, exposed wood trusses, and wrought iron chandeliers, opening seamlessly to the outdoor loggia for true indoor-outdoor living. Designed for entertaining, the estate features a movie theater, walnut-paneled library, billiard room with bar and wine cellar, formal dining room with dome ceiling and butler’s pantry, exercise room, and 6-car garage. The private backyard offers a resort-style setting with expansive entertaining areas, fireplace, built-in cabinetry, bar with Sub-Zero refrigeration, and pool bath—enjoyed from nearly every room. Exceptional details throughout include hand-carved mahogany entry doors, stone finishes, custom cabinetry, stain-grade windows and doors, cedar-lined closets, and extensive wood beam work. Quiet, private, and fully usable, this is a rare opportunity to own a legacy estate in one of Rancho Santa Fe’s most desirable locations.
