Is Your Land in the Green Belt?

Use our interactive Green Belt map above to quickly check whether your property or land is affected by Green Belt policy. Simply enter a postcode, address, or click directly on the map to view the planning context for your site.

Understanding Green Belt Planning

The fundamental purpose of the Green Belt is to prevent urban sprawl by keeping land permanently open. This does not mean development is impossible, but it does mean proposals are assessed more strictly under national and local planning policy.

The key planning consideration is often the impact on openness, alongside matters such as landscape, scale, design, and sustainability.

Winning Planning Permission for a New House in the Green Belt

Although it is highly controlled, it is possible to obtain planning permission for a new house on a Green Belt site. The most common routes to approval are as follows:

Replacement Dwellings. New homes replacing existing buildings may be acceptable where scale and impact are carefully controlled.
Conversion of Existing Buildings. Agricultural and rural buildings can sometimes be converted under permitted development rights or through full Planning Permission, subject to policy and structural suitability.
Rural Worker Dwellings. Housing may be permitted where there is a proven essential need for someone to live permanently on site.
Affordable Housing. Some forms of affordable or local-needs housing may be supported by policy in appropriate locations.
Exceptional Design (Paragraph 84). National policy allows for isolated homes of outstanding architectural quality in very limited circumstances.
Grey Belt and Previously Developed Land. Recent updates to national policy may support redevelopment of certain previously developed or underused Green Belt sites where openness is preserved.

Refusal Risks in the Green Belt

In our experience, applicants often contact us after attempting to submit a planning application in the Green Belt, only to find that they, or their original consultant, lack the expertise to address the specific policy and design challenges these sites present. Common reasons for refusal typically include:

Failure to demonstrate very special circumstances to justify development in the Green Belt.
Inappropriate scale, design, or siting that harms openness or visual amenity.
Insufficient assessment of landscape, heritage, or environmental impacts.
Inadequate supporting reports, such as transport, drainage, or ecology surveys.
Conflicts with Local Planning Authority policies or emerging local plans.
Poor engagement with consultees or lack of evidence that objections have been addressed.

We have extensive experience advising on Green Belt development. We can help you prepare proposals that respect openness and landscape constraints, address Local Planning Authority policies, and maximise your chances of securing Planning Permission.
