About this property
Nestled on a sprawling, park-like 0.57-acre double lot in one of San Marino's most coveted neighborhoods, this Georgian Colonial estate offers a rare blend of timeless character and modern luxury. Designed by architect Cyril Bennett, known for his design of the Pasadena Playhouse and the Raymond Theater, this property features a meticulously updated 1941 home plus a detached, oversized luxury 4-car garage, complete with a kitchenette, built-in appliances, and gorgeous 3/4 bathroom. This is an excellent bonus space for a home gym, catering prep, or game room with every amenity imaginable - air-conditioning, built-in cabinets, walk-in closet, finished floor, and 2 pull-down staircases to the huge plywood-decked attic storage area. From the moment you enter the home, you will recognize its sophistication. The grand foyer features a sweeping staircase and a high domed ceiling.

The gourmet kitchen is mise en place made manifest, equipped with Viking stainless steel appliances, farmhouse porcelain sink, quartz countertops, a breakfast nook and access to the elegant dining room. Beyond the main residence, the estate excels in versatility.
