The visionaries behind the architectural transformations at Mint Plaza continue their penchant for stunning-yet-sustainable design with a new collection of condos in one of the city's sunniest and most celebrated neighborhoods—and have managed to become San Francisco's very first residential project to be certified Gold by Leadership in Energy and Environmental Design (LEED™) For Homes Mid-Rise.

The building offers unique, eco-minded amenities like electric car-charging stations, abundant bicycle parking, and exclusive use of City CarShare vehicles parked on premises for all residents. And the Arc Light is located in one of the most transit-accessible areas of the city, with BART, MUNI and CalTrain almost literally a baseball's throw away—oh yeah, it's located a block away from AT&T Park, home of our world champion Giants.

The ultra-modern lofts—available in studio, one- and two-bedroom configurations—are kept aesthetically warm by incorporating a pre-existing, historic Townsend Street facade in its forward-thinking design.

In his book, Old Buildings, New Designs: Architectural Transformations (Princeton Architectural Press), architect and author Charles Bloszies advocates for this exact approach to modern city building: "Today, we embrace urban density because it requires less energy and resources. There is not a lot of raw land in this city, so instead of demolishing existing structures there is a new focus on transforming them.”

Arc Light Co. residences will be available for lease in late April of 2012. Pre-leasing tours can be scheduled by contacting arclightco@martinbuilding.com or calling 415.348.4630.
