The Underwood Estate was originally developed from the former World War II Prisoner-of-war camp after the war, in the late 1940s. A few examples of the surviving former PoW huts were visible until the early 1990s, when they were demolished. The original huts stood as early community buildings. In the early 1980s several huts and a water tower were also visible on the now Waltwood Park Drive area, this area belonged to the General Post Office and was used to house old telecommunications equipment until it was sold and demolished by British Telecom who took over the site when the organisation was privatised in the early 1980s. The land was subsequently sold to Westbury homes who built the Waltwood Park Drive Development of around 220 houses on the land.
