A Class Q conversion of a Gloucestershire agricultural barn into two homes has been refused on appeal because neighbouring dog boarding kennels could lawfully continue operating. Inspector G Sibley dismissed appeal 6010245 at Bassett Court Farm, North Nibley, on 23rd October 2026, following a September site visit.
Stroud District Council had questioned aspects of the proposed building works and the living conditions future residents would experience. The Inspector accepted the revised conversion works as permitted development, but found the evidence about kennel noise insufficient and the offered legal undertaking too uncertain to resolve it.
The distinction matters. I would treat the noise evidence and the enforceable legal mechanism as separate prior approval hurdles. A Class Q conversion may satisfy the physical and structural limitations of the General Permitted Development Order (GPDO) yet still fail the separate prior approval tests. Here, the legal status of an existing neighbouring use proved more consequential than the design changes made to the barn.
Why the Class Q conversion works were acceptable
The owners sought prior approval to change the agricultural barn into two dwellings under Schedule 2, Part 3, Class Q of the GPDO. The council objected partly to external steps, garden enclosures and other elements shown on the original drawings. At appeal, revised drawing 70014/06/100 revision C removed the external steps and added obscure glazing.
The Inspector accepted these limited changes without finding that other parties were prejudiced. He treated the garden structures and boundary enclosures as indicative, rather than as works for which Class Q approval was being sought. The remaining works consisted of changes to exterior walls, openings and services reasonably necessary to make the building function as two homes.
The council accepted that the existing building was structurally sound and capable of conversion. With the disputed steps removed and ancillary garden works excluded from the proposal under consideration, the Class Q conversion fell within the scope of the permitted development right. That finding did not amount to prior approval.
Why kennel noise became decisive
The barn adjoins dog boarding kennels authorised by planning permission S.14/0813/FUL. Although the applicant intended to close the kennel business and its licence was due to expire in March 2027, the Inspector distinguished those circumstances from permanent loss of planning permission. A business licence ending is not the same thing as a planning use becoming unlawful.
The council’s Environmental Health Officer had asked for a noise assessment. None was supplied. The Inspector considered intermittent dog barking capable of causing intrusive disturbance to the proposed homes and their outdoor spaces because of the close relationship between the uses. Without measurements or reliable mitigation evidence, acceptable conditions for residents had not been demonstrated.
This Class Q conversion therefore failed the noise test in paragraph Q.2(1)(b). The Inspector did not revisit whether housing was desirable in principle under Class Q. He examined the specific prior approval matters that the GPDO still requires an applicant to resolve.
Why the legal undertaking did not secure closure
The applicant offered a unilateral undertaking intended to stop the kennel use permanently before either dwelling was occupied. It also proposed demolition of the kennels and retention of that land as open space. The Inspector accepted that effectively securing the end of the noisy use could potentially address the problem, but found material weaknesses in the document submitted.
Clause 4 made the undertaking conditional on the ‘grant of the Permission by the Council’, without defining ‘Permission’. That wording left uncertainty about whether an appeal decision granting prior approval would activate the obligations at all. The undertaking also bound the owner and a defined red-edged site, while the kennels stood on neighbouring blue-edged land.
The Inspector could not be confident that a later purchaser of the kennel land separately would be bound to cease the use. References to successors in title and the blue land did not adequately resolve that concern. Removing the proposed demolition requirement, as the applicants offered, would not itself cure the uncertainty about the trigger or the land bound.
This is the important procedural lesson from the Class Q conversion. A legal agreement can be relevant to an identified planning harm, but it must operate in the circumstances of the decision being sought, bind the necessary land and remain effective after ownership changes. A broadly expressed promise is not enough.
Why conditions could not save the two homes
The Inspector also considered whether conditions could make the homes acceptable. Common ownership and the intention to stop operating the kennels suggested closure was achievable, but not that it would be permanent. A condition preventing occupation of the new homes whenever the kennels operated could effectively oblige residents to leave if the lawful kennel use resumed.
The suggested condition limiting the homes to kennel operators would not remove the noise exposure. Nor could a later acoustic scheme reliably solve the fundamental acceptability question when no assessment showed how much noise would reach the homes or how it could be mitigated. The Inspector concluded that those conditions would not offer a reasonable, effective solution.
Those findings mattered under paragraph Q.2(1)(e) as well. Independently of the noise assessment failure, the close relationship with the lawful kennels made the Class Q conversion undesirable in this location without an enforceable remedy.
The layout and privacy concerns were not decisive
Not all concerns about the proposal were sustained. The two homes would share parking and access, with visitors to one passing close to windows of the other. Their outdoor spaces would be compact and slightly awkwardly arranged, but the Inspector regarded them as identifiable, usable gardens.
Obscure glazing on the revised drawing could also be secured by a condition to protect privacy. Consequently, the dwelling layouts, shared access and gardens did not themselves make the scheme impractical or undesirable. The appeal failed on kennel noise and the legal safeguards, not on the basic suitability of the barn for conversion.
What applicants can learn from this Class Q conversion
Anyone promoting a Class Q conversion near a commercial or agricultural neighbour should check not only what that business is doing today, but what its existing planning permissions could allow tomorrow. Statements about an intention to close, a licence expiry or shared ownership may carry less weight than an enduring planning permission.
Where noise is an issue, acoustic evidence is most useful before a decision is reached. Where a neighbouring use is to cease, the proposed legal mechanism must identify the correct land, bind relevant owners and successors, and be triggered by the actual permission or prior approval decision. Leaving those matters uncertain until after approval risks repeating the problem seen at North Nibley.
The appeal illustrates the distinction between the physical limitations of Class Q and its prior approval requirements. Compare Planning Geek’s reporting on a Class Q appeal that failed on bedroom-space evidence and a Bromsgrove Class Q extension appeal. The decisive rules and evidence differ between cases.
