SAN FRANCISCO, CA
Site: 360,000 sf No. Stories: 19 stories
Sustainable Features: LEED-NC Platinum (registered)
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.
The vast untended lot stretching from Pine Street over to Bush Street has been left idle for years now, with proposals for a Heller-Manus designed office tower having fallen through, thwarted by the recession. Now that the city’s economy is booming again, new renderings for the 19-story tower at 350 Bush have surfaced on the CAC group’s website, and the building’s design seems to want to cater to younger workers, most of whom aren’t enthused by the idea of cubicles, fluorescent lighting or white walls. Interior renderings show open concept office spaces with modern design features and plenty of light. The exterior of the proposed tower is also a departure from the more traditional design originally proposed for the site, with all-glass cladding and little detailing or stonework. Thankfully, the historic Mining Exchange Building on Bush Street will be retained and renovated as part of the project. Though there’s no word on any exact timeline for completion, rather optimistic projections of a 2015/2016 delivery are floating around the web.
