Tom Watkins and Darron Copping wanted to build a house that would be home to them, their art collection and their two large dogs. Darron's passion for surfing meant it would also have to be near a beach. They already shared a timber beach house in a hamlet on the Sussex coast, and when a neighbour's bungalow came up for sale, they decided to buy it, demolish it and build a dazzling white modernist house in its place.
