Class Q equestrian use blocks four-home barn conversion appeal

A Suffolk Class Q equestrian use appeal has been dismissed after an Inspector found that a former poultry shed had most likely been used for a non-agricultural equestrian purpose after it ceased to form part of an established agricultural unit.

Appeal 6009854 concerned Green Farm at Lower Green, Stoke by Clare, where four homes were proposed under Schedule 2, Part 3, Class Q of the GPDO. Inspector S Simms BSc (Hons) MA MRTPI dismissed the appeal on 2nd October 2026, upholding West Suffolk Council’s refusal of application 25/1812.

The practitioner point is sharper than the facts might first suggest. There was no express planning permission or lawful development certificate for equestrian use of the appeal building. That did not establish that the intervening use had never happened. Class Q eligibility turned on the factual history of the shed and the evidence available to prove it.

Why the Class Q equestrian use mattered

The building was a large shed originally used to keep poultry. Permission was granted in the late 1970s to change the use of the wider farm, excluding the shed, from agriculture to a stud farm. That permission was implemented and the stud use continued.

The appellant’s case was that the appeal building had been part of an established agricultural unit, had later ceased to be part of it, but had not itself been used for any non-agricultural purpose in the meantime.

That distinction mattered because paragraph Q.1(b)(iii) of Class Q prevents development where a former agricultural site has, since ceasing to be part of an established agricultural unit, been used for any non-agricultural purpose.

The Inspector did not treat the existence of a stud farm elsewhere on the holding as enough on its own. He expressly accepted that equestrian activity elsewhere did not automatically extinguish the building’s previous agricultural use.

What changed the balance was the evidence about this shed.

At the site visit, the building was in reasonable repair and contained straw, including a fresh bale. Photographs supplied with the application showed horse boxes and other horse equipment inside. A photograph submitted to the council’s call for sites had described the structure as “Central barn and stabling”.

Taken together with the long-standing use of the wider holding, the Inspector found on the balance of probabilities that the building had been used for a non-agricultural purpose, “most likely equestrian”.

Our Class Q guide explains the current permitted development route and the wider limits that apply to agricultural and former agricultural buildings.

Class Q equestrian use: no permission did not mean no intervening use

One of the most useful parts of the decision is the treatment of planning history.

There was no explicit planning permission for an equestrian use of the building and no certificate confirming such a use as lawful. The appellant relied on that absence when arguing that the shed had not moved into a non-agricultural use.

The Inspector rejected the idea that the absence of a permission settled the matter. He said: “the limitation does not require such a use to be, or always have been, lawful.”

That is the key warning in a Class Q equestrian use dispute. A use can be relevant to the GPDO even if nobody applied for planning permission for it, nobody obtained a lawful development certificate and the planning register contains no neat entry announcing the change.

The question is factual. What was this building actually being used for after it stopped being part of the established agricultural unit?

That can be uncomfortable territory because historic rural uses are often informal. A barn may gradually become stabling, commercial storage, a workshop or part of another enterprise without anybody stopping to create a clean planning paper trail.

For an applicant, silence in the planning history is therefore not positive evidence of continued agricultural use. It is simply silence.

The Class Q gateway failed before the works were tested

West Suffolk had raised several other objections.

The council questioned whether the proposal would exceed the cumulative dwelling limits under Class Q, whether the proposed building operations went beyond what the GPDO allows, and whether the information submitted was sufficient for the prior approval assessment.

None of those points was decided.

Once the Inspector concluded that the building had been used for a non-agricultural purpose after it ceased to form part of the established agricultural unit, the proposed development was not permitted by Class Q. He therefore did not need to determine the cumulative limit, the conversion works or the adequacy of the submitted information.

That sequencing is worth remembering.

A Class Q application is not a full planning application where competing benefits can rescue a proposal that fails a threshold requirement. The building first has to qualify for the permitted development right. If the proposal falls at that gateway, arguments about design, housing delivery or the practical merits of conversion do not create a Class Q entitlement.

It also means that this decision should not be read as authority on the other disputed points. The Inspector did not decide whether the four dwellings would have breached the cumulative limits, nor whether the physical works were acceptable.

Evidence needed in a Class Q equestrian use dispute

For me, the practical lesson is to build the history before building the planning case.

Where a Class Q proposal relies on a former agricultural building, the evidence should establish when the building formed part of the agricultural unit, when that relationship ended and what happened to the building afterwards.

Useful material can include dated photographs, aerial imagery, farm accounts, invoices, tenancy records, livestock records, business records, historic sales particulars and witness statements from people with direct knowledge of the site.

The Green Farm decision shows that descriptions used in other planning or land promotion exercises can matter too. A call-for-sites photograph describing a “barn and stabling” became part of the evidence considered by the Inspector.

Physical evidence at the site may also carry weight. Horse boxes, equipment, fresh materials or adaptations can help an Inspector understand what a building has actually been used for. None of those features should be viewed in isolation, but together they may tell a persuasive story.

The same discipline applies where an applicant says apparent equestrian activity was genuinely agricultural. Horses can form part of an agricultural use in some circumstances, but that proposition needs evidence rather than assumption. Here, the Inspector specifically referred to the lack of evidence of agricultural horse use.

In a Class Q equestrian use case, a short written chronology prepared before submission can expose gaps early. If there is a period when the use of the building is uncertain, that is the point to investigate rather than hope it never becomes an issue.

Planning Geek analysis

This Class Q equestrian use decision exposes two unreliable assumptions.

The first is the council shortcut that says a stud farm somewhere on the holding means the barn must have lost its agricultural status. The Inspector did not accept that.

The second is the applicant shortcut that says no planning permission for a different use means no different use ever occurred. The Inspector did not accept that either.

The correct approach sits between them. Identify the relevant building, establish the agricultural unit it belonged to, identify when it ceased to form part of that unit and then test the evidence of everything that happened afterwards.

For advisers assessing Class Q equestrian use, that can save substantial work before a conversion scheme is commissioned. There is little value commissioning a full conversion package, structural evidence and detailed drawings if the building fails a basic Class Q history test.

It also matters when buying or valuing rural property. Marketing material may describe a barn as having Class Q potential, but that label is not a substitute for checking the factual use history. A building that once looked like an obvious agricultural conversion opportunity may have lost that route years earlier through an intervening use.

The appeal does not mean every trace of horse-related activity defeats Class Q. The Inspector was careful not to make that leap. The decision instead shows how a combination of the wider land use, photographs, physical contents and a lack of contrary agricultural evidence can satisfy the balance of probabilities.

That makes Green Farm a useful evidential case rather than a broad rule about horses and barns.

Read the decision

Appeal 6009854 was dismissed on 2nd October 2026 by Inspector S Simms BSc (Hons) MA MRTPI.

The Class Q equestrian use decision is particularly useful on paragraph Q.1(b)(iii) because it confirms that an intervening non-agricultural use does not need its own planning permission or lawful development certificate before it can defeat Class Q.
