To create the new Le Bon Bar, we designed a structure to sit atop the heritage walls of the existing building. This structure is perched on a platform that is supported on a series of legs that carefully attach to the existing heritage walls. Due to access restrictions, we deployed laser scanning to precisely measure the space, then worked closely with engineers to design balustrading, stair access, guttering, and provisions for power and waste removal. The design enables the bar to be inconspicuous from the street, in order to not obscure the design of the original façade.
