The development at 350 Bush Street incorporates the existing 1920s Mining Exchange with a nineteen-story, glass-clad tower and a five-story, mixed-use building. The complex offers tenants outdoor space at many levels, including setback roof decks and plazas. The project also includes replicating ornamental terra-cotta at the Mining Exchange’s pediment. SGH consulted on the building enclosure design for the new tower and the structural attachment of new terra-cotta.
