Britain built a 70-foot water tower disguised as a house in 1923; its 50,000-gallon tank was damaged by a wartime shell before the landmark became a holiday home

• Completed in 1923, the building concealed a tank with an original capacity of 50,000 gallons, while the structure below provided living accommodation.
• Known as the House in the Clouds, it was part of the development of Thorpeness, a planned holiday village on the Suffolk coast.
