The project encompassed the rehabilitation and seismic retrofit of 5 factory buildings and connecting structures on the National Register of Historic Buildings.  The buildings were repurposed for a new Fairmont hotel, which serves as the cornerstone project in the revitalization of the landmark and the surrounding square.

The site was originally designed in the style of an Italian Factory village with housing and work buildings built around a central garden.  The oldest building, the Woolen Mill, is pre-Civil War and was used to make uniforms for both Union and Confederate soldiers.  The other buildings were used in the manufacture of Cocoa, Chocolate and Mustard and date from the early 20th century.  The Clock Tower building is the youngest building and is significantly different in its reinforced concrete structure as opposed to the heavy timber and masonry structures of the other buildings.   In the 1960’s, the factory operations were moved elsewhere and the site was the first conversion of a historic building into a retail mall in the US.  The independent buildings were connected with stair towers and ramps and the central garden area was raised and convereted into a central parking structure with a plaza and various retail buildings on top.  The site, at this point, was added to the Historic Register.  In early 2000’s, city code required the seismic retrofit of the masonry buildings and the developer JMA had a vision to revitalize this premier San Francisco site.  The square is now a destination for high-end retail, wine shops, restaurants and the famous Ghirardelli chocolate shop.
