  Top-floor penthouse loft, 1,368 SF, two outdoor spaces, two-car parking, disclosures available. Stop by if you're in the neighborhood.

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.
