Westminster Abbey

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.

Jim Vincent, Clerk of the Works at Westminster Abbey said:

Bakers of Danbury have successfully managed access issues and restrictions whilst carrying out the works at the Abbey. The main access route into site is through the Great Cloister, which is a busy area of the Abbey accessible to the public from 9.30am every day.

We have found Bakers of Danbury to be considerate of the public and employees of the Abbey and have undertaken the works to the Abbey with the utmost care and attention at all times and look forward to continuing our working relationship with them in the future. The high standard of work is commensurate with the status of the building and is what is expected of contractors working at Westminster Abbey."

Value = £162,000

Location = Willingale, Essex

Architect = Simon Marks - Purcell

Summary = Restoration of church roof, including strengthening and alterations to meet modern regulations.

Challenge = Fitting a new compliant roof structure into the old C14th roof timbers without disturbing the original structure and pegged joints, or affecting the existing plaster and lath ceiling. Every new rafter had to be fitted bespoke, shaving millimetres off at various points along their lengths to allow it to fit in the roof space available.

Solution = Works included stripping tiles and battens and re-roofing using bat-friendly felt, batten and tiling with hand-made Tudor tiles. Carrying out timber repairs and strengthening to the roof structure. Installing secondary roof structure in softwood to meet modern regulations regarding rafter spacing. Adjusting and adapting rainwater goods to suit new roof.
