The 700-year-old castle near Darlington in County Durham is one of the most intact mediaeval structures in England. Buildings added to the estate in the 18th century have lain empty for decades, but thanks to the vision of its owners, Lord and Lady Barnard and a team of restoration experts, the site will enjoy a renaissance that can be enjoyed by tourists and the local community. 

The development project will include a new, purpose-built visitor information building known as The Round House. The Walled Garden will be redesigned and developed to provide an outdoor space where visitors can enjoy the planting or attend performances and events.  The Grade 2* listed Coach House and Stables will be restored and repurposed to provide  retail and interpretation spaces, while The Dutch Barn will be opened up to visitors for the first time to host events and activities including seasonal markets. Redundant for decades, the historic Vine House will be re-purposed as the Vinery Café and a new adventure playground will cater for four to 10 year olds.

The project team includes conservation architects Donald Insall Associates, heritage architect Francis Maude and garden designer Luciano Guibbilei.
