About this single-family home

Resting on a 1/2 acre corner lot in San Marino's exclusive Huntington Library neighborhood, 685 Chester Avenue is a timeless Mid-Century ranch ideal for planting roots. This single-story home offers elegant, light-filled living spaces, a private backyard with lush gardens, and a versatile 824 sq ft guest house complete with a full kitchen, living room, and bedroom ensuite. A grand, double-door entry opens to the home's gracious foyer with gleaming marble tiles. To the right, an elegant formal living room with intricate millwork and numerous windows offers the perfect setting for social club meetings, piano practice, or simply relaxing with a good book in front of the handsome fireplace. The heart of the home is found in the centrally located family room complete with skylights and a statement fireplace. Sliding glass doors dissolve the boundary between inside and out while offering peaceful views of the covered patio and lush gardens. Nearby, the kitchen features a large island, abundant storage, and a Sub-Zero refrigerator. From the living area, a hallway leads to three bedroom suites resting at the rear of the home, including the luxurious primary. A private fourth bedroom and a hallway bathroom are located off the foyer. The home's serene outdoor areas include a covered stone patio-ideal for weekend brunch-overlooking a grassy lawn and blooming rose garden. The secluded guest house at the rear of the property is updated and fully equipped for visiting loved ones or multi-generational living. Between the garage and the rear gate, you'll find a large and versatile space ideal for extra parking or a basketball court. Set in a picture-perfect neighborhood just blocks from the Huntington Library and San Marino High School, 685 Chester Ave is where the good life stops being an aspiration and becomes reality.
