Like its surrounding SoMa (South of Market) neighborhood in San Francisco, 355 11th Street is an eye-catching hybrid of old and new. And in the three years since this formerly derelict but National Register–listed plumbing warehouse was renovated into a LEED-NC Gold–certified mixed-use office building and LEED-CI Platinum–certified restaurant, it has become a community magnet. These attributes, among many others, garnered the project an AIA COTE Top Ten Green Project designation in 2010 and, this year, the inaugural 2013 AIA COTE Plus award.

Initially, the 14,000-square-foot, three-story project was intended as a multitenant office building, anchored and developed by its general contractor, Matarozzi Pelsinger Builders. (Click here for more details on the plans in ECOSTRUCTURE’s original profile of the building in 2009.) The architects from Aidlin Darling Design proposed that the ground floor be outfitted for a restaurant rather than rented out as additional office space; it required a zoning code variance but has yielded both higher rent and greater social enhancement for the surrounding neighborhood. Aidlin Darling also convinced the client to transform half of the parking in front of the building into a private courtyard.

“One of my professors always said, ‘We’re architects. We’re responsible to our community,’ ” Joshua Aidlin, AIA, partner at Aidlin Darling Deisgn explains. “We can be guides toward responsible development. Clients are usually just dealing with their specific program. If you can open their eyes to opportunities, that’s exciting. Whenever we take on a new project now, we can’t stop seeing the opportunity of the bigger picture.”

With its rooftop divided between solar panels and green-roof plantings, as well as having a perforated zinc façade that shades the building from heat gain and natural ventilation throughout, the expectations were high: for 355 11th Street building to be 79 percent more efficient than code. In 2011, however, the building was 94 percent better, with 103.3 percent of the offices’ energy needs provided by the panels. The extra 3.3 percent is fed back into the grid. The restaurant performed 69 percent more efficiently than what is stipulated by code.

The zinc façade was in part a response to a city design-review requirement. It stated that no new visible windows could be added to the east and west façades in order to preserve the original early-20th-century structure’s monolithic, industrial character. But with cross ventilation crucial, the design instead adds disguised new openings rather than eliminating them. With perforations varying from 1/16 to 1 inch, the façade shades the hottest corner of the building but is still transparent enough for occupants to easily see outside. And while staff has increased by 40 people over the past three years, there has been only a 17 percent turnover rate. The 65 percent of employees who commute by bicycle or mass-transit has surpassed the previous 40 percentestimated. “We feel like the building is an expression of our philosophy,” Matarozzi Pelsinger partner Dan Matarozzi explains.

Reclaimed materials, particularly wood, give the interior its charm, including a hull in the restaurant made from reclaimed whiskey oak barrels extending through the main dining level, as well as bar and tabletops made from reclaimed oak barn beams. Old or new, all major building components were fabricated on site or within a 15-mile radius. “It’s a lot about creative problem solving,” Aidlin says of the team. “It’s probably the most pure example we have in our office of collaboration yielding profound results.”
