A row of a new houses in Richmond, British Columbia
Our new paper on where to build on London’s Green Belt is out now. Below is part of the press release we sent to the media; for the full press release, click here. To read the whole paper, click here.
London must build on low quality Green Belt spaces around existing commuter infrastructure to solve its housing crisis, according to a new paper from the Adam Smith Institute.
Building on 20,000 acres of the Metropolitan Green Belt (roughly 3.7%) would create room for the 1m new homes needed, estimating 50 houses per acre; nearly all of which could be built within 10 minutes walk of a station.
The paper, A Garden of One’s Own: Suggestions for development in the Metropolitan Green Belt, identifies specific areas where tens of thousands of dwellings can be built, and points out how providing the housing Londoners need does not require ‘concreting over’ the countryside, destroying amenity, or overcrowding.
The author of the paper, Tom Papworth, considers the five main justifications given for the green belt: to check sprawl; to prevent towns merging; to safeguard the countryside; to preserve historic towns; and to force land recycling; and notes that many pieces of land currently designated that way do not meet any of these.
For example, there is an area of land between Hainault, Barkingside, Chadwell Heath and Colliers Row, totalling about 1,200 ha—or 60,000 dwellings at standard densities outside of London—where none of these purposes apply. It is already swallowed by Redbridge, it would have no impact on merging with London, there are no historic towns, and land recycling is irrelevant.
The table below lays out the total land available of different types that could be used to fill the 20,000 hectare demand, assuming standard densities. At inner London densities of 120 dwellings/ha it would take much less land, and at lower densities of 30-40/ha it would take more.
