San Francisco Chronicle architecture critic John King features 1 Tenth in his piece about how glass skins are remaking once-homely buildings in the city. Originally called the “M2” building, 1 Tenth was built in the 1970s as a furniture warehouse. To discourage natural light, which would fade the furniture, the building was clad with large concrete panels inset with tiny windows. After Shorenstein Realty Services purchased the building and decided to repurpose it for commercial offices, RMW architecture & interiors designed a reskin that included cutting away the exterior concrete panels and replacing them with floor-to-ceiling window wall. Twitter has subsequently leased most of the building.
