Ghirardelli Square

San Francisco, California

Built at the turn of the century to house the Ghirardelli Chocolate factory, and granted historic landmark status in 1982, Ghirardelli Square has been a place of intrinsically San Franciscan identity for generations. Although Ghirardelli Square remained profitable for years after its first conversion from a factory into an open air retail venue in the 1960s, the increasing presence of tourist-oriented retail reduced the Square to a mere traveler’s destination in the 1980s and 90s. Countering that trend, Hornberger + Worstell was commissioned to design The Fairmont Heritage Place, a 100 room fractional ownership hotel with accompanying food and wine focused retail.

Hornberger + Worstell’s project began with a full seismic upgrade of the Chocolate, Cocoa, and Mustard Buildings. Employing a unique in-wall core strengthening system, Hornberger + Worstell fortified Ghirardelli’s unreinforced brick masonry walls without damaging any of the historic facades or character-defining features.
