Listing agent Florence Mattar of Coldwell Banker Realty in Beverly Hills calls it “an unprecedented, unparalleled estate of unmatched beauty and elegance.” One peek inside the breathtaking and groundbreaking $75 million Bel Air mansion, which debuted on the market back in May, and it is immediately clear why Mattar opted for such a glowing description of the property.

Beginning with the views: a sweeping panorama takes in the ocean, Catalina Island, a twinkling array of city lights and the distinctive white profile of the Getty Center.

Architecture by Tag Front celebrates the organic modernist aesthetic for which the L.A.-based firm is known. Indoor-outdoor living mixes with refined textural and sculptural details throughout its 20,000 square feet. Walls of glass vanish entirely to allow seamless flow between gracious rooms with nine-foot ceilings and the adjoining wraparound patios, lawns, and gardens suitable for entertaining on a grand scale. It’s the perfect setting for displaying art – and there is already plenty of it throughout the residence. “Prepare to be captivated,” says Mattar.

Gated and private, the nine-bedroom residence is surrounded by majestic landscaping on a 1.1-plus acre lot. Curated materials – Portuguese limestone, Calcutta marble, fine millwork – set a sophisticated stage for the most luxurious appointments – an Italian kitchen, a 20-seat theater, a wine room, a tranquil spa, a gym, an elevator and a fully-equipped caterer’s kitchen with a dumbwaiter.

The grounds match the home for beauty, serenity and resort-style amenities, with an ocean-view, infinity-edge curved pool with a Baja shelf and curved pool deck, a lighted grass tennis and sport court, a reflecting pool, an outdoor living room and a lovely dining pavilion.

More than a home, as Mattar says, “this property is a lifestyle.”
