The repair shop you are referring to, specifically the one known from the BBC show "The Repair Shop," is located at the Weald and Downland Living Museum in Singleton, West Sussex, England. The workshop where the repairs mostly take place is called The Court Barn, though other nearby buildings like the Victorian smithy and Wagon Shed are also used. This living museum is just north of Chichester and is known for its collection of historic rural buildings, making it a picturesque and educational location.
