Property Description

The top floor of the Mullen Building rarely comes available. This corner penthouse loft sits atop one of SoMa's most distinctive buildings, a 16-residence boutique conversion of a 1920s warehouse originally designed by architect George Hauser. Step inside and the architecture reveals itself immediately. A full wall of industrial steel-framed windows rises to soaring ceilings, flooding the space with natural light and framing Twin Peaks and the San Francisco skyline beyond. Radiant-heated concrete floors, a wood-burning fireplace, and a sculptural steel staircase rising to the loft suite create a space that feels both expansive and distinctly personal. What truly distinguishes this residence is its rare connection to the outdoors. A private patio off the main living level extends the home's entertaining space into the open air, while a second terrace off the upper loft suite offers sweeping city views and a quiet retreat above the surrounding neighborhood. The shared rooftop deck, located on the same level, provides panoramic views stretching across San Francisco. The chef's kitchen is outfitted with a Wolf range, Viking appliances, quartz countertops, and a herringbone tile backsplash. The open floor plan flows effortlessly from kitchen to dining to living, preserving the volume, light, and flexibility that define authentic loft living. Two en-suite bedrooms, in-unit laundry, and deeded two-car tandem parking complete the offering. Tucked away at the end of a tree-lined cul-de-sac, the Mullen Building offers a rare sense of privacy and calm just moments from SoMa's restaurants, cafes, cultural destinations, transit connections, and the city's evolving technology and innovation corridor. A rare top-floor loft where the energy of the city remains close at hand and the quiet of a cul-de-sac becomes your own retreat.
