In the world of L.A. real estate, where neighborhoods overflow with impressive mansions, there are few properties that can truly take your breath away. But 613 Mountain in Beverly Hills is among those few. The home was built in 1926 by famed architects Koerner & Gage, whose Spanish Renaissance-style Beverly Hills City Hall, one of the most admired structures in California set the stage for the beauty and elegance of this truly remarkable residence.

A meticulous restoration and top-to-toe remodeling over three years and completed in 2007 unveiled an exceptional combination of original period architecture, old world elegance, and modern convenience. Exquisite details including hand-cut wood floors, exotic stones such as onyx,  original antique chandeliers, and moldings and light fixtures that came from a 16th-century Venetian castle are just some of the distinctive details found throughout the home.

As prestigious locations go, it doesn’t get much more grand than the exclusive Mountain Drive. North of Sunset Boulevard on one of the most desirable streets in one of the most exclusive areas of Beverly Hills, Mountain Drive contains some of the most coveted real estate in all the world—undoubtedly why the son of the founder of General Motors commissioned Koerner & Gage to build the home in such a prime locale, why they named it Villa di Sogno, literally “house of dreams” in Italian, and why they kept it in the family for more than 50 years.

An extended drive lined with olive trees is straight out of a Tuscan tour guide, and the Italian Villa at the end is a worthy companion. Sited on a 1.24-acre knoll, the home was featured in the third edition of Architectural Digest…and it’s easy to see why. The residence opens to 13,227 square feet of refined space, starting with a grand foyer, ballroom, music room, tea room/solarium, and formal dining room. On the same level is one of the more spectacular kitchens you will ever see, replete with Jerusalem stone, double six-burner range, two generous islands, built-in coffee station, wood-burning pizza oven, walk-in refrigerator, and service pantry.

On the lower level, a 10-seat movie theater, wine vault, and game/billiards room create an entertainment mecca, Upstairs is a media room, an art studio, and three family bedroom suites plus a junior master guest suite in addition to the grand master suite with dual baths and walk-in closets, roll-down projection screen, sitting area, wet bar, romantic antique French fireplace, and large terrace.

A Moroccan-tiled terrace is your invitation to the spectacular grounds, where formal gardens including rose and vegetable gardens, outdoor kitchen, loggia, cabana, lighted sport court, and mosaic-tiled pool and spa create as magnificent a presentation as that found inside.

A home of this caliber also deserves and requires a host of amenities to provide comfort, convenience, and support to the homeowners. Here, two maid’s suites and an elevator are presented, as well as a Crestron system that serves as the home’s nerve center.
