Data from the London Development Database shows that 37,931 homes have been started on public land during the years 2016/17 to 2018/19 (the last year that comprehensive data on permission starts is available). The breakdown by year is as follows:
Units started on public land
These figures have been calculated by plotting the site location recorded on LDD against the sites on the Map of Publicly Owned Land (https://maps.london.gov.uk/public-land/). All units within a permission share the same site location and start date. Developments delivered in phases may have multiple permissions, and while permissions that have been fully superseded have been excluded from the data, there may be some double-counting of units where only a partial superseding of a larger permission has occurred.
