873 Union Street is a fully reimagined Edwardian residence in Russian Hill, blending classic San Francisco architecture with modern design. Rebuilt from the studs, the home offers the scale and livability of a single-family residence within an intimate three-unit building. Spanning approximately 2,090 square feet across two levels, this four-bedroom, three-bathroom home is thoughtfully designed for both everyday living and entertaining. The main level is anchored by an expansive open kitchen featuring custom cabinetry, a Bertazzoni appliance suite, and wide-plank oak flooring, flowing naturally into the living and dining areas. The upper level includes a well-appointed primary suite with an en suite bathroom and walk-in closet, as well as two additional bedrooms and a full bath. A versatile lower level, finished with polished concrete floors, offers flexibility as a media room, guest suite, or private fourth bedroom. Indoor-outdoor living is seamlessly integrated, with two private decks and direct access to a landscaped shared garden just off the kitchen, creating a natural extension of the home. Additional features include in-unit laundry, deeded one-car side-by-side garage parking with interior access, and the ease of a boutique three-unit building. Moments from the dining, shopping, and neighborhood amenities of Russian Hill and North Beach, 873 Union Street offers a compelling combination of scale, design, and location.
