Eight Bungalows on Green Belt Land, Approved First Time in Benfleet
Planning permission has been granted for eight detached bungalows on Green Belt land in Thundersley, Benfleet. No appeal. No affordable housing requirement. Approved at the first attempt.
That last part matters more than it sounds. Green Belt applications are usually measured in years, refusals and appeal references. This one was decided on its first outing, because the case was built around the questions national policy actually asks.
The short answer: part of the site was previously developed land, which national policy allows to be redeveloped in the Green Belt. A planning Inspector had already found the land next door to be grey belt. And the scheme was kept below the threshold for major development, so the stricter rules for larger Green Belt schemes did not apply. Together, those three things gave the council a clear route to say yes.
Why does a bungalow scheme matter?
Bungalows have quietly become one of the rarest new homes in England. McCarthy Stone reported that just 1,833 were built in 2020, compared with 9,347 in 2000. More recently, NHBC figures showed bungalow registrations falling again in 2025 while every other house type rose.
The reason is simple arithmetic. A single-storey home needs more land for the same living space, so on most sites the numbers favour two-storey houses. Demand has not gone anywhere, though. Downsizers, people planning for later life and families with relatives who need step-free living are all chasing the same small pool of homes.
That is why we are so pleased with this one. Rayleigh Road will be eight detached, single-storey, accessible homes: exactly the type of housing that is hardest to find locally.
How do you get planning permission on Green Belt land?
There is no single route. The National Planning Policy Framework sets out a list of exceptions where building in the Green Belt is not treated as inappropriate. Since December 2024, and carried into the revised Framework published on 17 August 2026, that list has included grey belt land. Two routes did the work at Thundersley.
Route one: previously developed land
Part of the site was previously developed land, often called PDL or brownfield. National policy has long allowed previously developed land in the Green Belt to be redeveloped, subject to tests on the effect on openness. The careful work is in the evidence: showing exactly which parts of the land count, what was there before, and how the new homes relate to it.
Route two: grey belt next door
Grey belt is Green Belt land that is previously developed, or that does not strongly contribute to checking urban sprawl, stopping neighbouring towns merging or preserving the setting of historic towns. The Government's Green Belt guidance explains how it should be assessed.
Before we applied, an Inspector had already looked at the land immediately next door and found it was grey belt. An appeal decision does not bind the next application, but a council needs a good reason to reach a different view on neighbouring land with the same edges and the same relationship to the town. We used that finding alongside the previously developed land case, rather than relying on either one alone.
Why did staying below the major development threshold matter?
For housing, major development means ten or more homes, or a site of 0.5 hectares or more. Cross that line on Green Belt land and the Golden Rules come into play, with requirements for affordable housing, infrastructure and access to green space. National policy also says affordable housing should not normally be sought on schemes that are not major development.
We made sure the scheme sat below that threshold. It kept the proposal small, proportionate and deliverable, and it kept the planning argument focused. The number of homes on a site is as much a planning decision as a commercial one, and here eight bungalows made a stronger scheme than a larger number of houses would have.
What does this mean for Castle Point?
Thundersley sits in Castle Point, a small and densely populated borough whose adopted Local Plan dates from 1998. The council's new Castle Point Plan is going through examination. Until it is adopted, applications like this are judged on national policy and on their own merits, which makes a well-evidenced first application all the more important.
It also raises a bigger question. If the homes a borough most needs are the ones the market least wants to build, where do they come from? Our answer is small, carefully argued schemes on land that others have written off.
What can landowners learn from Thundersley?
Look at what has happened next door. Appeal decisions on neighbouring land are public and can contain findings you can build on.
Map the previously developed land precisely. Old buildings, hardstanding and their surroundings can change the whole case.
Choose the number of homes with policy in mind. A smaller scheme below the major development threshold can be easier to approve and quicker to deliver.
Aim to get it right first time. Every refusal adds months, cost and a planning history that the next application has to overcome.
Could your Green Belt land be next?
If you own Green Belt land that has been written off, or you are a developer with a site stuck in planning, it may deserve a second look. Our planning consultancy team can review it and tell you honestly whether there is a route through. If you would rather sell, you can find out what your land could be worth, or email us directly at hello@wearemillen.com.

Frequently asked questions
Can you build bungalows on Green Belt land?
Yes, in some cases. Building in the Green Belt is allowed where a proposal falls within one of the exceptions in national policy, such as redeveloping previously developed land or building on grey belt land that meets the relevant tests. Our eight bungalows in Thundersley, Benfleet were approved this way at the first attempt.
What is previously developed land in the Green Belt?
Previously developed land is land that is or was occupied by a permanent structure, including the land around it. It excludes agricultural and forestry buildings, and land where the remains of a structure have blended into the landscape. National policy allows previously developed land in the Green Belt to be redeveloped, subject to tests on openness.
What is grey belt land?
Grey belt is Green Belt land that is previously developed, or that does not strongly contribute to checking the sprawl of large built-up areas, preventing neighbouring towns from merging or preserving the setting of historic towns. It was introduced in December 2024 and carried into the revised National Planning Policy Framework of August 2026.
What counts as major development for housing?
For housing, major development is ten or more homes, or a site of 0.5 hectares or more. On Green Belt land, major housing schemes must meet the Golden Rules on affordable housing, infrastructure and green space.
Do small Green Belt schemes have to include affordable housing?
National policy says affordable housing should not normally be sought on schemes that are not major development, although designated rural areas can set a lower threshold. Our Thundersley scheme sat below the major development threshold and was approved with no affordable housing requirement.
Does an appeal decision on neighbouring land help a planning application?
It can. An appeal decision does not bind a council on the next application, but findings about neighbouring land, such as whether it is grey belt, are a material consideration. A council would need a good reason to reach a different view on land with the same character.
How do I find out whether my Green Belt land has development potential?
Start with the planning history of your land and the land around it, including any appeal decisions. You can also ask We Are Millen for a review through our planning consultancy, or for an estimated value through our sell your land page.
