About 350 Bush Street
350 Bush Street is a 19-story office tower San Francisco’s Financial District. The new glass tower 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 the modern office building. The building will provide 360,000 square feet of office space with a dramatic galleria at the street level as well as a mid-block pedestrian link between Bush and Pine Streets.
The intersection of the modern glass curtain wall and the historic facade demonstrates a balance between antique and modern, expressing a unique vocabulary of forms and shapes.
LEED Gold certified, 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 neighboring 500 Pine Street for an expansion of St. Mary’s Square. Current tenants include Twitch, Altassian and Publicis. This building was completed in 2018.
