"Built in 1648, Donnington Castle House showcases the stunning classic design and symmetry of the Restoration period.

"Original architectural and design details abound throughout the house. These include floor to ceiling large pane sash windows, original shutters, leaded light windows, window seats, panelled rooms, dado rails."

The large cellar is formed of five rooms, one with the original brick arched wine bins, two with bespoke wine storage, capable of storing up to approximately 5,000 bottles. 

The huge attic floor, spanning the footprint of the house, was originally servants quarters, and could now be turned into self-contained accommodation, offices, or "even a teenager's retreat."
