Drapers’ Hall – Livery Hall Roof Void

The Drapers’ Hall was rebuilt in 1772. After a duration of two hundred & forty-seven years, the timbers which support the roof required attention. Restore London oversaw the installation of a newly designed tensioning system, along with a bespoke system of repair.

Each truss was surveyed individually, and where the structural integrity was found to be compromised, the Jakob tensioning system was installed. A total of twelve Jakob tensioning systems were installed.

Two redundant service voids were removed & new joists installed to strengthen the floor whilst twenty-four bespoke shake straps were installed. Ten Simpson strong ties were then installed to spread roof loading and eliminate unnecessary loading points onto the historic timbers.

Restore London surveyed & produced a detailed conditional survey of the fibrous plaster ceiling, cornice & wads. A considerable number of the wads were found to be failing. The wad’s & ties suspending the ceiling were strengthened by installing stainless steel wire fixed adjacent to each failed plaster & canvas wad.
