Under the instruction from Ptolemy Dean Architects Ltd (Westminster Abbeys Surveyor of the fabric) Bakers are currently carrying out roof works to the medieval South Triforium and the Great Cloister within Westminster Abbey.
The roof works will be completed in time for the opening of a new museum and gallery, located in the Abbey's medieval Triforium, next year. After being hidden from public over 700 years, the Triforium will become “The Queen's Diamond Jubilee Galleries”.
70ft above the Abbey floor, the new gallery will provide visitors with magnificent views down over the Abbey buildings and the Palace of Westminster. Roof works carried out by Bakers involve stripping the existing roof, recasting original lead and re-leading part of the South Triforium and part of the Main Cloister.
A full overhaul of the rainwater goods is also being carried out, with a combination of new and refurbished lead downpipes, hoppers and chutes being fitted. A new hopper, corbel stone and 22 metre downpipe has been introduced, formed to mirror the Christopher Wren era hoppers that are already in use.
Bakers are increasing the gradient of the Triforium roof by increasing the fall of the lead bays (compliant with lead sheet association guidelines). Other structural repairs include reinforcing 300-year-old oak primary rafters using a flitch plate repair and other associated structural repairs to the oak roof.
Other works include careful rehoming of monuments and statues from other parts of the Abbey onto the Triforium floor.
With the improvements to the rainwater goods, Bakers will undertake the renewal of the below ground drainage within the Great Cloister, which will also include the exciting addition of a fountain to be positioned in the centre of the Cloister, formed on York Stone paving with a lead cistern fountain. These works will continue into Spring 2018.
