George meets architect Andy and his girlfriend Ana, who are trying to restore a listed water tower into an uber-modern 21st century home. But at what personal cost? Andy Critchlow surprised his girlfriend Ana Ferguson when he bought a stunning, cylindrical Grade II listed water tower in Congleton, Cheshire, at auction - without even seeing the inside. Andy dreams of converting this building into a cutting-edge 21st century home, which means selling their current property and moving in with his parents during the nine-month build. As a director of his own architectural practice, Andy tackles the build with huge drive and determination. Meanwhile, George goes on a historical mission and discovers how this monumental landmark sitting proudly on a Cheshire hill saved the lives of the people it overlooked.
