A masterwork by Niche Interiors, this upper-level showpiece is a study in volume, light, and design claritycapturing the essence of authentic San Francisco loft living. Polished concrete floors, custom full-height wood paneling, expansive window walls, artisan-painted wall murals, and curated fixtures create a layered, architectural interior set against iconic city and landscape views beyond. The residence unfolds with a scale that is increasingly rare. Soaring ~12+ foot ceilings and dramatic south-facing glass define the main living volume, drawing in exceptional natural light throughout the day. Views span Twin Peaks, Sutro Tower, and the city skyline, balanced by softer garden outlooks that provide privacy and calm. The open plan is both expansive and highly adaptable, with distinct zones for living, dining, and work that maintain the integrity of the loft's architecture. Thoughtfully designed by Niche Interiors founder Jennifer Jones, the interiors reflect a refined, cohesive visionwhere custom detailing and a curated palette of modern finishes elevate the space with subtle sophistication. Two well-proportioned en-suite bedrooms offer flexibility for a range of lifestyles or use, while in-unit laundry, generous storage, deeded TWO-car parking, and a shared building rooftop complete the offering. Originally constructed in the 1920s and reimagined in 2002, the Mullen Building is a boutique 16-residence elevator building. Positioned at the end of a tree-lined cul-de-sac in South of Market, it offers a rare sense of privacy just moments from the city's AI, tech-capital, and and commercial core. A compelling balance of industrial heritage and contemporary designset within one of SoMa's most distinctive buildings.
