The Studio

The Cathedral Studios workshop is based in the heart of the City of Canterbury, set inside the Cathedral precincts. The workshop is equipped with conservation, painting and designing spaces and a glazing workshop. We have our own lead milling facilities and darkroom photography studio. The glass in our care is stored in climate controlled and secure areas. The studio is able to accommodate small and large scale projects.


Stained glass conservation and restoration at Canterbury Cathedral started relatively early, and was entrusted to four generations of the same family (Austin and Caldwell) for over 130 years. George Austin (Senior) was first appointed Surveyor to the Cathedral in 1819. This was a significant time and was the starting point towards the strong interest and campaign in the repair and conservation of the stained glass windows in the Cathedral


In 1972 The Cathedral Studios Stained Glass Workshop was established and still undertakes the care and conservation of the stained glass windows at Canterbury Cathedral. A part of The Cathedral Studios today also work in the conservation and restoration of stained glass with commercial clients who include English Heritage, The National Trust, Westminster Abbey, Gloucester Cathedral, Parish Churches, Castles, Museums, Stately homes and Private homes throughout the country. The Studio is one of the leading stained glass conservation studios in the UK.
