For six years Bruno and Denise Del Tufo stared at the large concrete water tower at the bottom of their garden trying to figure out what to do with it. It’s a very rare object – a square water tower on stilts designed by architect Edwin Lutyens, who built it to supply the manor house nearby.

The planners were open to persuasion so they approached an architect who came up with a bold, uncompromising extension in metal, glass and concrete. Denise and Bruno were keen to keep the original structure visible so the new house is threaded between the legs of the water tower.
