Set on an expansive lot and framed by mature oak trees, the residence pairs a refined stucco exterior and steel framed windows with marble flooring, intricate crown molding, custom millwork and statement designer lighting throughout. A dramatic double height foyer with a sculptural curved staircase opens to the soaring great room, formal kitchen and inviting family living area. Designed for elevated entertaining, the home features a Sub-Zero, Wolf and Cove appliance package, oversized island, full catering scullery, walk-in pantry, bar and wine cellar. Three primary-quality suites—including two on the first floor—create exceptional multi-generational flexibility. The owner’s retreat includes a 14 foot recessed ceiling, fireplace, patio deck access, spa bath with a fully marble clad shower and a walk through closet with private laundry. Additional highlights include five ensuite bedrooms, a paneled study, dedicated home theater, game room, flex space, whole home audio system, three fireplaces, a second floor balcony, three car garage and built in outdoor kitchen. The expansive backyard offers exceptional space for a future pool, cabana and sports court.
