The British public still believe the countryside is being concreted over and overestimate the amount of land that has been developed, according to research by Linden. A survey by the housebuilder found that only 19% of people estimated correctly that 11% of land has been developed. The remaining 81% thought that between 29% and 59% was under cement. Only 13% of respondents guessed correctly that only 1% of land would be needed to meet the housing needs of the next 50 years. Linden chief executive Philip Davies said: “A long and sustained campaign against housebuilding in this country since the second world war has left a legacy of negative attitudes and suspicion. Although most people in the UK are aware there is a chronic housing shortage, often resulting in their children being priced out of the local area, their perceptions of actual levels of development in the UK are very wide of the mark.”
