350 Bush Street is a 19-story office tower which incorporates the historic landmark San Francisco Mining Exchange Building as its principal entry. The historic existing building, originally constructed as the Mining Exchange in 1923, was later used briefly as the Stock Exchange and subsequently as the Curb Exchange through the 1930s. The historic exchange hall will be used as a grand lobby for a modern office building. The building will provide 360,000 sf of office space with a dramatic galleria at the street level as well as a mid-block pedestrian link between Bush and Pine Streets. By utilizing rusticated stone cladding with glass curtain wall accents and ornamental balconies, Exchange Place demonstrates a balance between antique and modern, expressing a unique vocabulary of forms and shapes. Seeking LEED Platinum certification, the building utilizes various environmentally advanced technologies. The site is distinctly complex, involving various neighborhood constraints. As such, the approval process resulted in the incorporation of provisions for outdoor space and the conveyance of rooftop space on a neighboring parcel for expansion of St. Mary’s Square.
