Project Details

Arc Light Co. is the dramatic transformation of an underutilized and distressed historic electric light company into contemporary lofts.

The stunning 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. Arc Light Co. originally served as the historic California Electric Light Company, Station B, and is listed as a contributory building to the South End Historic District.

The beautifully renovated development features 94 contemporary lofts — a mix of studio, one bedroom and two bedroom units in a new six-story steel and glass building set back from the Townsend Street facade. Outstanding amenities include a north and south facing roof deck with a custom spa, fitness center, lush interior courtyards, enclosed garage parking, and Michelin Star restaurant, Saison located within the restored historic brick-lined interior on Townsend Street.

Arc Light Co. was the first residential building in San Francisco to receive LEED for Homes Mid-Rise Gold Certification, as well as LEED Platinum certification. It also participated in the California Multifamily New Homes Program, the Go Solar SF Program and the New Solar Homes Program.
