Green Belt Planning Permission

Obtaining Green Belt Planning Permission For Building on Green Belt

What is Green Belt?

Green belt is a special designation of land which is preserved for its own sake. It is designated by local authorities to resist urbanisation. As such it can be incredibly difficult to obtain planning permission to build on these areas.

Green Belt land covers an estimated 12.5% of the country (over 1.6 million hectares). Some Local Planning Authorities like Epping Forest, Warrington, and Cheshire have as high as 99.4% of their area designated as Green Belt. These areas have a high degree of land set to pasture, parks, forests and open countryside.

The National Planning Policy Framework (NPPF) states that “The Government attaches great importance to Green Belts. The fundamental aim of Green Belt policy is to prevent urban sprawl by keeping land permanently open; the essential characteristics of Green Belts are their openness and their permanence”.

The Green Belt serves five purposes:

  1. To check the unrestricted sprawl of large built-up areas;
  2. To prevent neighbouring towns from merging into one another;
  3. To assist in safeguarding the countryside from encroachment;
  4. To preserve the setting and special character of historic towns; and
  5. To assist in urban regeneration, by encouraging the recycling of derelict and other urban land.

As well as working on a range of developments, a core element of our experience  in this area is submitting planning applications on Green Belt land, and obtaining valuable green belt planning permission for replacement dwellings and house extensions.

Please see our dedicated case-studies page for further information. See the Green Belt map on the right.

The Green Belt continues to be a hotly debated topic at local and national Government level, with discussions about reducing its extent or allowing more homes to be built. The Government has recently introduced a further classification of land within, called Grey Belt, where development on previously developed land that does not contribute to the specific aims of the green belt is allowable

At plande, we continue to keep abreast of these ongoing issues and work with relevant stakeholders to influence how Green Belt development should evolve.

What Development is allowed in the Green Belt?

The NPPF states that the construction of new buildings as inappropriate in the Green Belt and that “Inappropriate development is, by definition, harmful to the Green Belt and should not be approved except in very special circumstances.”

Green Belt replacement dwellings are an allowable exception under national and local green belt policy.

A Green Belt replacement dwelling is a new home built on the site of an existing dwelling, where the original property is demolished and a new house is constructed in its place.

How Can I Get Green Belt Planning Permission

There are several exceptions that may allow you to get planning permission for development on land designated as Green belt: 

  • Removing land from the Green Belt – this may sound obvious but it notoriously difficult to achieve. The NPPF state quite clearly that there needs to be exceptional circumstances for land to be removed. It could be, for example, there is an elevated demand for new homes. Councils need to demonstrate that every other avenue has been explored first. For example, they need to prove prove they have exhausted all possibilities of using Brownfield sites, that density in current builds has been optimised, and they have considered the needs of neighbouring councils. The process of obtaining planning on Green belt is time consuming and highly political, with a relatively low chance of success, especially considering the competition that exists between other housebuilders and stakeholders.
  • For agriculture and forestry – rebuilding houses for agriculture and forestry workers. Buildings may be erected on green belt where workers are required to live in a certain place, for example, for animal welfare, under special circumstances.
  • Limited infilling or the partial or complete redevelopment of previously developed sites – as long as the openness of the Green belt is maintained then brownfield (The development of previously developed land), can be built upon.
  • Provision of appropriate facilities which would normally be seen to be suitable for rural/ countryside locations – For example, cemeteries and outdoor sporting facilities. where the openness of the Green Belt is maintained.
  • The extension or alterations of buildings (including house extensions) – this can be acceptable as long as the overall proportions of the building are not exceeded
  • Replacement of buildings (including dwellings) – providing the new building is of the same size and proportions.
  • Limited infilling in villages – under limitations provided in the Local Plan, strictly limited, affordable housing for local communities may be allowed.
  • Certain other works – including re-use of buildings; material changes of land use.

Green Belt replacement dwellings are an allowable exception under national and local green belt policy.

A Green Belt replacement dwelling is a new home built on the site of an existing dwelling, where the original property is demolished and a new house is constructed in its place.

The NPPF states that “the replacement of a building, provided the new building is in the same use and not materially larger than the one it replaces.”

What does materially larger mean?

In most cases between 15 and 30%, but there is no definitive legal definition of what the term means. Nationally, there are cases which give guidance in attempting to ascertain what ‘materially larger’ means. In addition, each Local Planning Authority has their own definition when considering green belt replacement homes.

The two calculations help to dictate or plan the strategy for a plot with an existing house.

Green Belt dwellings usually still have permitted development rights, so it is often part of our strategy to look at how the existing property could be extended by permitted development before design work begins on the replacement dwelling.
The policies for house extensions within the Green Belt have a key difference in that such calculations are based on the “original” house whereas green belt replacement homes calculations are based upon the “existing” size of the home.

Can I remove existing outbuildings in the Green Belt to build a bigger house?

We also look at removing additional outbuildings on site as part of the planning strategy. These contribute to the total amount of buildings on site, and a single building volume is often preferable to many smaller structures. It is important to ensure that you definitely are not going to need these buildings in future, because permitted developments are often removed when granting planning permission in the Green Belt.

Plande has a wide range of experience of green belt replacement dwellings and justifying whether a development is “materially larger”. The following case-studies provide some interesting examples and are not necessarily an exhaustive list.

The brief for a green belt replacement dwelling is often to create a house either as large as possible or significantly larger than either the existing house or than policies would allow. While this would normally not be acceptable, we have obtained green belt planning permission for a replacement home for far in excess of what either policy or the LPA would normally allow.

Do I have to build on the existing building’s footprint in the Green Belt?

Each site needs to be considered on its own merits, but it is usually preferable to replace a dwelling on a similar footprint, unless there are other issues that would prevent this.

Can I Build a House Extension on Green Belt?

Green Belt House Extensions are an allowable form of development as defined by the National Planning Policy Framework (NPPF) as well as Local Planning Authorities planning policies.

The NPPF provides for “the extension or alteration of a building provided that it does not result in disproportionate additions over and above the size of the original building”.

We expect that most LPAs would allow a percentage of between 15 and 30% in either in floor space or volume, over the “original house”.

The term “original house” is critical, in that it means the house as originally constructed or as it stood in 1948. Any extension to the original house needs to be taken into account when investigating further green belt house extensions. In many cases, houses already have extensions larger than the LPA allow. However, this is not always the end of your options, as will be highlighted in the case studies below.

Understanding the original house and the scale of previous extensions is critical as a starting point before any design work is undertaken.  We are have often been approached after designs have been produced (or even considered by the Council), and still succeeded in obtaining green belt planning permission.

There may still be scope to extend a previously extended dwelling in Green Belt, by considering permitted development (PD) rights. These schemes can show that a larger extension of the property is possible, and can be used as a ‘fall back’ option. The PD proposals can also be used to argue that a house of the same size or volume would not be a disproportionate addition, even if it is larger than local policies would typically allow.

Greenbelt Planning Loopholes

The above is a simplistic summary of the exceptions and policies, so please contact us with your specific project.

Also, there are many greenbelt planning loopholes that you may not be aware of, but we are well versed in. While these don’t allow you to break the law, they can provide a useful way to get your greenbelt planning application sanctioned by exploiting some simple holes in the regulations. Examples include:

Common Greenbelt Loopholes:

  • Redeveloping a brownfield site or previously developed land.

With the new definition of grey belt land, developing previously developed land is now allowable, as long as it does not strongly contribute to the functions of the green belt. Although existing brownfield sites within the green belt can be developed, new buildings previously had to be of a similar size and in a similar location to those they replace, preventing sites from being redeveloped to their maximum potential. The new rules widen the definition of previously developed land to include areas of hardstanding, meaning that previously developed sites can now be developed more efficiently.

  • Converting barns, sheds and other old agricultural buildings.

The reuse of existing buildings within the green belt is generally deemed to be acceptable, as the development will not impact on openness. The buildings need to be of permanent and substantial construction, and should not need substantial reconstruction. Additionally, the design must fit in with the local surroundings in terms of materials and building styles.

  • Gap sites, Infill developments between existing properties on underutilised land.

In many cases an infill development will not harm any of the five purposes of the green belt, and as such we have successfully put forward the case for development of the land.

  • Affordable housing schemes for the local community.

This exception is only applicable if there is an identified need for affordable housing in the local area.

  • Agricultural worker’s homes – although restrictions apply.

If your development is to support agriculture or forestry then this would be allowable, although restrictions apply.

Green Belt Very Special Circumstances

The NPPF states that inappropriate development should not be approved except in ‘Very Special Circumstances’ or VSC. No definitions or examples are provided.

There has to be a very strong reason for planning to be granted on green belt, and it needs to clearly outweigh the harm to the green belt itself and any other harms. Each reason, taken on its own may, not be enough to amount to a very special circumstance but combined with other planning arguments could outweigh the harm to the green belt.

Such circumstances can include:

  • Need. For example, if the local council are unable to demonstrate a five-year housing land supply, this could increase the potential for green belt development opportunities. Similarly, self-build and custom build housing and rural worker accommodation may be considered, if the local authority cannot meet their targets for these construction types.
  • A development in green belt which will boost the local economy. Proposals which will have an economic benefit to the local area may be judged to outweigh any potential harm to the green belt.
  • Reuse of derelict land that sits within the green belt. If the development has the potential to provide significant visual or environmental improvements, this could be taken into consideration.
  • Provision of essential infrastructure for the community.
  • Fall back positions or permitted development allowable development.
