Brownfield land is defined as land that has been previously developed. As previously developed land, airfields are therefore regarded as brownfield land. However, if a building only occupies one section of open land there is an assumption that the remaining open land would not be developed.
The general suitability of brownfield sites for housing is a matter for councils. Planning policy recognises the significant contribution that aviation makes to economic growth across the country and is clear that councils should consider the role of airfields in serving business, leisure and emergency service needs. Aviation policy is also clear that maintaining access to a national network of airfields is vital to the continuing success of the sector.
In July 2015 the Government announced its intention to grant automatic permission in principle on brownfield sites identified in brownfield registers. The Government has taken this commitment forward in the Housing and Planning Bill.
Decisions about the suitability of sites in brownfield registers will be set out in regulations. The Government will consult on these criteria and the wider policy in due course.
I am assured by my ministerial colleagues that work will continue to be done with the aviation sector to ensure the current policy relating to development on airfields is better understood.
