Half a block from the 1,491-acre Presidio and framed by sweeping Golden Gate Bridge views, 37 Walnut is a 1916 Beaux-Arts residence that was completely remodeled and seismically retrofitted in 2011, pairing period character with modern comfort. Approximately 4,920 square feet across four levels, the home offers four bedrooms, four full and one half baths, radiant heat, a security system, integrated Sonos audio, and a side-by-side two-car garage, ready for immediate occupancy. Stone stairs rise to an arched front door and a grand entry finished in black walnut hardwood. At the front of the home, the formal dining room centers on a wood-burning fireplace, with French doors opening east to a wrought-iron balcony. A discreetly placed powder room, coat closet and china cabinet lead to the heart of the home: an open chef's kitchen with extensive custom cabinetry, stone countertops and Wolf and Subzero appliances. The kitchen flows to a deck overlooking the tranquil mid-block green space toward the Presidio. The accompanying living area with gas fireplace and enclosed bar with approximately 92-bottle wine refrigerator and ice maker make for effortless relaxing and entertaining. A wide, open staircase beneath a skylight ascends to the bedroom level. The primary suite captures spectacular Golden Gate Bridge and Presidio views and includes two walk-in closets with an integrated laundry and a luxurious spa-inspired bath. A generous bedroom suite occupies the front of the home, alongside a custom study that can be reimagined as a nursery. The uppermost level is the home's signature. Beneath the mansard roof, arched dormer windows define a charming front bedroom, and a gallery-like hall leads to a remodeled full bath. Four steps up, the space opens into a light-filled family room with a fireplace and panoramic views of the Presidio and Golden Gate Bridge, complete with refrigeration and a dishwasher for easy hosting. Stairs descend to a private west-facing deck, an ideal setting for a sauna and cold plunge. The lower level offers a living area with substantial built-in cabinetry, opening directly to the private garden. Double pocket doors reveal a spacious bedroom suite, a natural guest or au pair retreat, with room to envision a home gym opening to the garden. The large garage, second laundry, and storage complete the home. The trails, open spaces, and playgrounds of the Presidio are moments away, as are the shops and cafes of Sacramento Street and Laurel Village.
