A single dwelling on an infill plot in a Green Belt village

8 min readBy PlanScope Editorial Team

An illustrative walkthrough of a one house application on a gap between two cottages in a washed over Green Belt village, where the whole case turned on the meaning of limited infilling.

A green belt infill plot application succeeds or fails on two questions that get settled before anyone looks at the design. Is the site in a village, as a matter of fact and degree, and does filling this particular gap count as limited infilling within the exception in national Green Belt policy. Answer both yes and the development is not inappropriate, and the case becomes an ordinary one about design, amenity and access. Answer either no and you are arguing very special circumstances for a single house, which almost never works.

What follows is illustrative rather than an account of a particular application.

The plot and why it looked developable

A paddock of roughly 0.09 hectares between two detached cottages on the single street of a village of perhaps 80 houses. Post and rail fence to the road, a mature hedge to one side, a slight fall to the rear. Services in the verge. Two houses either side, each about 25 metres from the boundary.

The vendor marketed it as a building plot. The buyer, a self-builder, did the obvious checks: no listing, no conservation area, no tree preservation order, flood zone 1, no protected species obviously present. What the particulars did not say, and what the buyer did not check before exchange, was that the whole village sits inside the Green Belt.

That is a common sequence. Green Belt is not a constraint that shows up on a standard search in the way a flood zone does, and it is not visible on the ground.

Checking whether the village was inset or washed over

The first job after exchange was to open the adopted local plan's policies map.

Villages in the Green Belt fall into two categories. An inset village has been excluded from the Green Belt by the local plan, with a defined settlement boundary drawn around it, and Green Belt policy does not apply to land inside that boundary. A washed over village remains within the Green Belt, and Green Belt policy applies to every plot in it.

This village was washed over. So the proposal had to fit an exception or be inappropriate development.

Two practical notes. The distinction is set by the development plan, so it changes when the plan changes, and a village inset in an emerging plan is not inset until that plan is adopted. And some plans identify washed over villages with their own infill policy setting out what is acceptable locally, which is more useful than the national wording because it is specific to the area.

The limited infilling exception and its wording

National Green Belt policy treats the construction of new buildings as inappropriate, with a list of exceptions. One of them is limited infilling in villages.

The wording carries three tests and each is contested in practice.

Is the site in a village. The Framework does not define a village. Inspectors approach it as a matter of fact and degree, looking at the number of dwellings, whether there is any community facility such as a church, hall, shop or school, and whether the group reads as a settlement rather than a ribbon of houses along a lane. A dozen cottages strung out over half a mile is usually not a village.

Is it infilling. Infilling means filling a gap within an otherwise built-up frontage or group. A plot at the end of a row, extending the settlement outwards, is not infill however small it is.

Is it limited. This is about scale relative to the gap and the settlement, not about the number of houses in the abstract. One house in a single plot gap is the clearest case. Three houses on a paddock that happens to sit between two dwellings usually is not.

The scheme here was one house on a gap 28 metres wide between two existing dwellings, with the village having a church, a hall and a pub. Both the village test and the infill test were arguable in the applicant's favour.

Openness and the evidence prepared

Where the exception applies, the development is not inappropriate, and there is no requirement to demonstrate very special circumstances. But openness still matters, because the local plan and the design policies still apply, and officers often assess the effect on openness even where they accept the exception.

Openness has a spatial aspect, meaning the absence of built development, and a visual aspect, meaning how much built form is apparent from surrounding land. The Supreme Court considered this in the Samuel Smith case and treated visual impact as a matter of planning judgement rather than a mandatory consideration, which is why officer reports handle it inconsistently.

The evidence prepared was deliberately plain:

  1. A site plan showing the building line of the two neighbouring cottages and the proposed house set on the same line.
  2. A section through the site and the road showing ridge heights relative to the neighbours.
  3. Photographs from four points on the public highway and from the footpath crossing the field behind, with the proposed ridge indicated.
  4. A statement of the developed footprint as a proportion of the plot, with the remainder as garden.

The design followed from that rather than the other way round. A single storey and rooms in the roof, ridge below both neighbours, footprint pulled forward to align with the frontage, rear garden left open to preserve views through to the fields.

The case was set out in a Planning Statement that dealt with the exception first, in its own section, before touching design. Officers read Green Belt cases in that order and a statement that buries the exception test on page nine is harder to recommend.

Neighbour and parish responses

Four objections and a parish council comment. The objections were about the loss of a green gap, precedent, and the access onto a road with no footway.

Precedent is worth taking seriously because it is the argument officers find hardest to dismiss. The answer is not that precedent is irrelevant. It is that the exception is site specific: this gap, between these two buildings, at this width. Saying so, and identifying the other gaps in the village that would not meet the test, is more persuasive than asserting that each case is decided on its merits.

The parish council was neutral but asked for a condition removing permitted development rights, which the applicant offered without resistance. On a Green Belt infill plot that is a sensible trade. It costs a future extension and it removes the officer's concern that a modest house becomes a large one by stealth.

The highway point was dealt with by a visibility splay drawn to the standard for the road's recorded speed, with a short length of hedge set back into the site.

The officer recommendation and the outcome

The officer accepted the village test, accepted that the gap was infill, and concluded the proposal was limited. That made the development not inappropriate, and the report then dealt with design, amenity and highways in the ordinary way. Permission was granted under delegated powers with conditions on materials, landscaping, the visibility splay, and removal of permitted development rights.

The application took about fourteen weeks, against the eight week target, mostly waiting for the highway authority.

Had the officer taken a different view on any of the three tests, the application would have been refused as inappropriate development, and the appeal would have turned on whether the harm to the Green Belt by reason of inappropriateness, plus any harm to openness, was clearly outweighed by other considerations. That is a hard test for one house, as the pattern in Green Belt refusals and very special circumstances at appeal shows.

What the decision means for similar plots

Three lessons carry across, and the first is the expensive one.

Check the Green Belt designation and the inset boundary before exchanging, not after. A plot in a washed over village is worth materially less than the same plot in an inset one, and the difference is visible on the policies map in two minutes.

Frame the application around the exception. A planning statement that argues design quality and treats Green Belt as background gets refused, because the officer has to reach a conclusion on inappropriateness before anything else.

And be honest about the gap. Where the site is a paddock rather than a gap, or the village is a hamlet, the exception does not apply and no amount of good design changes that. A scheme in that position needs either a different policy route or a different site, as the reasoning in a Green Belt stables and menage walkthrough illustrates.

Note: the Green Belt chapter of national policy has been revised more than once in recent years, including changes to how land that contributes less to Green Belt purposes is treated. Check the current wording before relying on any of this.

Frequently asked questions

What is the difference between an inset and a washed over village?

An inset village has been excluded from the Green Belt by the local plan, with a settlement boundary drawn around it, so Green Belt policy does not apply inside that boundary. A washed over village remains within the Green Belt, and every plot in it is subject to Green Belt policy. The policies map shows which applies.

How is a village defined for the infilling exception?

National policy does not define it. Inspectors treat it as a matter of fact and degree, considering the number of dwellings, the presence of community facilities such as a church, hall, shop or school, and whether the group reads as a settlement rather than a ribbon of houses. A scattered hamlet usually fails the test.

Does limited infilling mean only one house?

Not necessarily, but the scale has to be limited relative to the gap and the settlement. One dwelling filling a single plot gap between two existing houses is the clearest case. Several dwellings on a paddock between two buildings is usually not limited infilling, even where the paddock is enclosed on both sides.

Do I need to show very special circumstances for an infill plot?

Not if the proposal falls within the limited infilling exception, because it is then not inappropriate development. Very special circumstances only arise where the development is inappropriate, and for a single market dwelling that test is very hard to meet. Getting the exception accepted is the whole case.

Will the council remove permitted development rights?

Often, on Green Belt sites, to stop a modest house becoming a large one through later extensions. Offering the condition yourself is usually a sensible trade, because it addresses the officer's concern about incremental growth and costs only future flexibility, which you can always apply for later on its merits.
