More Land May Not Mean Cheaper Housing

"The research tracked house prices, completions and housing land supply over periods of 10 years or more."

"It suggests that proposals to relax planning controls could 'unleash a new wave of urban sprawl' in the country."

"The government is currently considering proposals that would see minor developments such as conservatories no longer needing planning permission, where there is judged to be little impact on neighbours."

"Campaign to Protect Rural England policy director Neil Sinden said: 'Evidence uncovered by this study suggests the government needs to rethink its planning policies for housing.'"

"'The relaxation of planning controls, which it is pursuing, will encourage builders to use more greenfield land rather than redevelop more difficult urban sites.'"
