The House in the Clouds is a water tower at Thorpeness, Suffolk, UK. It was built in 1923 to receive water pumped from Thorpeness Windmill and was designed to improve the looks of the water tower, disguising its tank with the appearance of a weatherboarded building more in keeping with Thorpeness's mock-Tudor and Jacobean style, except seeming to float above the trees. The original capacity of the water tank was 50,000 imperial gallons (230,000 l) but during the Second World War, the House in the Clouds was hit by gunfire from anti-aircraft guns based at Thorpeness. The water tank was repaired using its own steel, which resulted in a reduced capacity of 30,000 imperial gallons (140,000 l).

In 1977 the water tower was made redundant by a mains water supply to the village, and additional living space was created. In 1979 the main water tank was removed to fully convert the building into a house. The building currently has five bedrooms and three bathrooms; it contains a total of 68 steps from top to bottom and is around 70ft high.
