Building conservation

We protect historic buildings and buildings in the wider landscape. Our building conservation team works hard to ensure they are preserved for ever, for everyone using traditional conservation techniques

Our biggest conservation challenges

The library at Blickling Hall, Norfolk

Protecting Blickling's library  

Drafty windows, encroaching damp and constant light exposure mean life in a 400 year old building is not easy for a book. With over 12,000 volumes in their care, the staff at Blickling Estate in Norfolk are beginning a mammoth 5-year project to protect the books.

The hidden painting in Morris' bedroom

Pre-Raphaelite discovery at Red House 

Concealed behind a wardrobe at Red House in Kent, conservation staff have made a startling discovery. Originally thought to be two painted figures, the artwork in Morris' bedroom has now been revealed as a whole wall painting and is believed to be the work of William Morris and his friends, all of whom are renowned Pre-Raphaelite artists.

Specialising in everything from paper and paintings to furniture and frames, the team can be seen in the studio every week from Wednesday to Saturday.
