15 th April 2021 12:58 pm Housebuilders should be required to sign delivery contracts when they are granted planning permission to ensure that homes are completed within a set timescale and that valuable land is not left empty, a think tank has argued. A report by the Centre for Policy Studies, released today, argues that planning permission should not be a “one-way gift” and that developers should be held to their side of the bargain. Currently, receiving planning permission boosts the value of land without creating an obligation to build, which causes a bottleneck. The report argues that this concentrates the supply of land in the hands of the large housebuilders.
