Rehabilitation and addition to an historic brick and steel leatherworking warehouse in the Western SOMA district into a new mixed-use property. New program will include a restaurant/pub at the subterranean level, high-tech office space at the first floor and mezzanine, and 12 new residential units at the third and fourth floor. Fourth floor units will pop through the roof with new sawtooth penthouses. The roof deck will be developed as a “park the sky” using the new topography of the penthouse roofs.
