George meets builder Mark Horton who has for years harboured a dream to live in a unique house. With this in mind he bought an 18th century folly with plans to convert it himself into a luxurious family home. On the 'Buildings at Risk' register for ten years Bath Lodge is just a derelict shell, with no access road or utilities. Architect George Clarke is on hand to advise and support, as well as turn detective as he uncovers the history behind this mysterious building. Mark is ready for the challenge, but disaster strikes three months in when the bank pulls his loan.
