SAN FRANCISCO—Shorenstein Properties LLC says that LEED Gold certification has been achieved at 1 TENth, a newly redeveloped class A office building located in the Mid-Market submarket of San Francisco. The building received Gold certification under the LEED Core and Shell rating system.

1 TENth, formerly known as 875 Stevenson Street, was built in 1975 as an expansion to the historical 1355 Market Street known as the “San Francisco Mart and Western Merchandise Exchange,” offering wholesale home furnishings to design professionals and retailers. Shorenstein Properties acquired the building in March 2011 on behalf of its ninth investment fund with the intent to modernize and upgrade the Property to a class A standard for creative office use.

The newly re-clad 1 TENth is a cutting edge 10-story office structure comprised of 338,000 square feet. Construction began in April 2013 and is currently 78% leased by Twitter and Fitness SF. Twitter will take occupancy in 2015 and Fitness SF by the fall of 2014. The redevelopment, designed by RMW Architecture includes a seismic upgrade, installation of a new unitized glass curtain wall, upgrades to the mechanical, electrical, plumbing, fire protection, life safety, and security systems, and renovated restrooms and lobby. 1 TENth and 1355 Market Street are joined by a recently constructed landscaped plaza that creates a cohesive urban campus environment.
