ARC LIGHT CO.
Designed and developed by Martin Building Company, the dramatic Arc Light Co. project located at 21 Clarence Place in San Francisco’s South Beach neighborhood, utilizes modern and visually light materials to differentiate innovative new architecture from the historic character of the building. The beautifully renovated development will feature 94 contemporary lofts — a mix of studio, one-bedroom and two-bedroom units available for lease — in a new six-story steel and glass building set back from the Townsend Street façade. Outstanding amenities include, a north and south facing roof deck with a custom spa, grilling area and fitness center, elaborate interior courtyards, enclosed garage parking, and a two-story restaurant located within the historic brick walls on Townsend Street.
Committed to unparalleled excellence in design using sustainable building standards, Arc Light Co. is on track to be the first residential building in San Francisco to receive LEED™ for Homes Mid-rise Gold certification.
Arc Light Co. originally served as the historic California Electric Light Company, Station B. The building was designed to house arc and incandescent lights used to generate electricity for electric light service. The arc light preceded Thomas Edison’s incandescent light bulb and was used for lighting streets and commercial buildings. By 1888, California Electric Light Company was satisfying San Francisco’s flourishing demand for electricity. Arc Light Co. is listed as a contributory building to the South End historic District.
