Green Belt and grey belt land wanted in Hampshire

The Green Belt and grey belt land that interests us around Hampshire

Hampshire includes the cities of Southampton, Portsmouth and Winchester, the north Hampshire towns of Basingstoke, Farnborough, Aldershot and Fleet, and a large rural area. The New Forest and South Downs National Parks, several National Landscapes and Green Belt on the Dorset border in the south-west all constrain land. Typical sites include edge-of-town fields, farm buildings, infill plots and urban brownfield land.

• Previously developed land in the Green Belt, such as yards, nurseries or old buildings
• Green Belt land on the edge of towns that is already enclosed by development
• Sites with a defensible boundary such as a road or railway
• Land with or without earlier promotion

Nutrient neutrality advice has applied across much of south Hampshire because of the Solent's protected habitats, and coastal schemes contribute to recreation mitigation for overwintering birds. The M3 and M27 corridors carry most planned growth, with smaller sites in market towns such as Alton, Andover and Romsey.

What decides whether a site in Hampshire works

Since 6 August 2026, non-major development on sites of 0.2 hectares or less in England has generally been exempt from mandatory biodiversity net gain, unless priority habitat is affected. That makes many small sites simpler to bring forward.

English councils keep brownfield land registers, and some previously developed sites can be granted permission in principle, a quicker way of establishing whether housing is acceptable before technical details are settled.

Some land in Hampshire is designated Green Belt. If your land is within it, it may still qualify as grey belt or previously developed land under national policy, subject to the Golden Rules.
