Lomond analysed current land usage looking at the total area of designated green belt land across England, before looking at how many homes could be delivered on just 1% of the current green belt and the added market value this would bring to the housing market.
Labour has pledged to take a brownfield-first approach to tackling the housing crisis when attempting to deliver its ambitious target of 1.5m new homes over the next five years. However, it has also pledged to create a grey belt which will see the reclassification of low-grade green belt land such as low environmental quality sites containing defunct agricultural buildings.
One such example of a grey belt site is a disused garage in Tottenham, which currently can’t be re-developed due to its designation as a green belt site, despite it being far from green.
England’s green belt covers an estimated 1,638,420 hectares, or 16.4bn square metres. This equates to almost 13% of England’s total land area with the majority of the green belt used for agriculture (65%) and forest, open land and water (19%), whilst 16% is already classified as developed use for infrastructure such as roads.
The average new home requires a land plot with an estimated size of 222 square metres, meaning that the entire green belt could facilitate the construction of 73.8m new homes.
