Welcome to 1854 Jefferson Street, a rare house-like Marina residence reimagined for a refined Modern Marina lifestyle and delivering the feel, systems, and livability of a new home within a classic Marina setting. Set on one of the Marina's quietest, widest streets - and literally steps from the Marina Green, yacht clubs, Crissy Field, the Palace of Fine Arts, the Presidio, waterfront trails, and Chestnut Street - this two-level lower residence offers exceptional scale, true indoor-outdoor living, and an extraordinary private garden setting. The main level is bright, elegant, and highly livable, with wide-plank European oak floors, expansive windows, south-facing French doors, and a rare walk-out balcony. The open-concept kitchen, dining, living, and bar areas create a flow rarely found in the Marina, designed for comfort and entertaining. The chef's kitchen features Wolf and Sub-Zero appliances, Dekton counters, an oversized breakfast-bar island, custom cabinetry, and an adjacent bar area with secondary sink, filtered water, and wine refrigeration. The generous living area features a fireplace and a flexible additional zone for conversation, home office, reading lounge, or expanded dining. Two en suite bedrooms - including a large suite with dual sinks, soaking tub, walk-in shower, a well-sized powder room, full laundry room and abundant storage complete this level. Downstairs, the primary garden suite is a true private retreat, with a grand bedroom opening through French doors to the landscaped patio and garden oasis. The suite includes a spa-inspired bathroom, walk-in closet, and generous adjoining spaces ideal for a sitting room, home office, fitness area, nursery, or media lounge. This rare indoor-outdoor primary suite creates a private sanctuary for al fresco dining, entertaining, play, gardening, or peaceful relaxation. A rare permitted transformation included a new foundation, seismic and structural steel upgrades, reconfigured floor plan, new electrical, plumbing, HVAC, insulation, lighting, windows/doors, radiant heated bathroom floors, custom millwork, integrated speakers, abundant storage, private storage closet, interior garage access, and dedicated parking. Smart-home infrastructure includes commercial-grade Ubiquiti networking, Lutron smart lighting, and smart entry. 1854 Jefferson combines the comfort and scale of a house, the ease of modern living, rare private outdoor space, and the best of Marina living.
