George Clarke meets Cheshire couple Andrew Jones and Michele Gibbons, who plan to turn an 85ft art deco water tower into the six-storey 'end house' of their dreams. The conversion proves an incredible challenge for the builders, as they must cut through double reinforced concrete to build new floors and fit over 20 new windows. It takes almost a year to get the tower wind and water-tight as, meanwhile, the couple must come to terms with fact that, despite a dislike of art deco furniture, they need to furnish their towering example of architectural history in a fitting style.
