Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, pursuant to the Answer of 6 June 2025 to Question 53925 on Green Belt: Planning, what definition her Department uses for a built-up area; and what level of density or rurality provides that development on residential gardens is considered construction on brownfield land.

The definition of Previously Developed Land is set out in Annex 2: Glossary of the National Planning Policy Framework. It excludes land in built-up areas such as residential gardens, parks, and allotments.

The National Planning Policy Framework, and associated Green Belt guidance, do not introduce a definition of a built-up area.
