St Mary’s Church is a Grade 1 listed building with parts dating from 1247, the interior having been altered more frequently to reflect fashion & need.

The brief involved the removal of the existing pews, suspended timber floor & adjacent radiators. The resultant exposed sub floor was excavated to the prescribed level, this was then progressively filled with an insulation system in preparation for the underfloor pipework. Following this work ceramic tiling & screed topping was installed. To this 25mm Clipsham Stone tiles were laid with a 100mm edging detail abutting the existing Victorian tiled floor.

Other works involved the provision of surface mounted electrical sockets, repairs to the internal wall with lime render, decoration with a limewash & a tiled Oak ramp with handrail to the Sanctuary.

All these works were to be carried out with minimal disruption & damage to the fabric of the church particularly the Father Willis organ.

Storage & parking was a particular issue requiring materials to be delivered on a just in time basis. Resultant debris was stockpiled.

This was achieved by the construction of a temporary transparent enclosing structure which contained any resultant dust & provided a physical barrier to those visiting the church.

It was necessary on occasion for the works to stop to accommodate funeral services & recitals.

A fine example of how the sympathetic use of new technology & materials can be incorporation within a listed building.

“Overall we are very pleased with your performance on this project: it has gone extremely well. There will be a formal celebration of the completion of this work, which has had many years of gestation, in the New Year and we will extend an invitation to Pilbeam and your subcontractors in due course.”

– Nick O’Riordan, Chair of Fabric Team
