Don’t forget about those PD rights!

Roderick Morton • 14 August 2025

In 2014, the claimant built an extension and outbuilding on the back of a semi-detached family house which it turned into 3 self-contained flats. For good measure, it linked the extension and outbuilding. The outbuilding, which was bigger than the house, was said to be a gym and office. Enforcement action was taken. The notice was upheld on appeal.


This decision was challenged in the High Court and, following success for the appellant at a permission hearing, remitted by consent back to the inspectorate for redetermination on the basis that the inspector had failed to consider the availability of PD rights for the extension and outbuilding. On redetermination, the second inspector upheld the notice in the same way as the first. This second determination was also challenged in the High Court. The challenge was not resisted by PINS and the matter went back to a third inspector for a third determination!


16 possible permutations (based on various possible uses of the main house and various extension and outbuilding combinations) were put to the third inspector; in the end, the appellant pursued only 2. The inspector rejected the appellant’s favoured approach of two flats plus extension in the main building and a non-residential ancillary outbuilding. However, the inspector granted permission for the second option ie main building as a single dwellinghouse with extension and with the outbuilding removed to create adequate amenity space for the house.  To secure this, the inspector imposed a condition restricting Class E PD rights to build any future outbuilding. This was not enough for the appellant who appealed the decision yet again.


The basis of the challenge was that the inspector was said to have stated at the hearing that he did not think he had power to remove Class E rights by condition and the parties had agreed with him. In the decision, he was said to have changed his mind without notice to the parties. It must be said that there was some factual doubt about this; the inspector himself did not recall making such a statement and evidence was that, if made, it was made in a context that did not cover the second option. In any case, the challenge was put on the basis that the parties were denied the opportunity to address the possible condition, not that it was necessarily impossible to impose one.


The inspectorate argued that there had been such an opportunity, that it was addressed in the council’s statement of case, and that the only reason the extension was retained was the removal of the outbuilding so that, even had the condition been discussed, there was little the claimant could have said against it. The claimant argued that the condition removed his right to construct a smaller, and truly ancillary, outbuilding. 


The court sided with the appellant. The inspector had raised the possibility of a smaller outbuilding as a concept but found that he had no details which would allow him to reach a decision on it. The court held that an opportunity to discuss the condition would have allowed discussion of such a possible outbuilding and allowed finessing of the condition. There was a procedural unfairness in the failure to do so and that required that the decision be reconsidered. The challenge succeeded.


Interestingly, and somewhat unusually, it seems that the matter was not remitted for reconsideration. Instead, the parties were invited to agree a position or make submissions to the court. The judge said “this is not an opportunity to re-argue the merits”.


Two other grounds of appeal were dismissed. In particular the court accepted that the inspector’s view that the outbuilding was not required for a purpose incidental to the enjoyment of the main house as a dwellinghouse was one he could reasonably have come to. The inspector had not simply looked at size relative to the main house but had considered other matters such as proposed use and the amount of space required for proposed contents of the outbuilding.


It is not unusual for decision letters to depart somewhat from the manner in which the case it put by the parties, particularly in written representation appeals. To some extent, that is part of the decision process. Sometimes, inspectors will canvas views ahead of the decision, sometimes not. For the most part, the court will defer to inspectors on matters which they have properly considered. The danger comes from the matters they did not consider at all.  Holes can almost always be picked in a decision letter and those based on procedural failure often have a better chance of success.  Particularly when the party has 11 years of post-enforcement notice rent as three self contained flats to fund the picking of the holes.

Given its portrayal of the planning system so far, it is almost a given that season 3 of Clarkson’s Farm will not accurately present the detail of the Diddly Squat appeal decision. Here is our take. The decision is here. In summary, the LPA won almost all of the enforcement points. But simply being Jeremy Clarkson is apparently a material consideration which alters the planning balance! While he is popular, his celebrity is such that his farm shop will create significant problems beyond those of an ordinary farm shop and the inspector decided that these are problems which have already been accepted in granting his existing permission. Fewer of the harms to the AONB can therefore be attributed to the additional elements of the use. And these harms are outweighed by the economic benefits, benefits which are a result of his celebrity. So permission was granted for his farm shop and café and the associated parking and toilets. Clarkson’s popularity will be re-assessed in 3 years as the permission is time limited. Perhaps the inspector knows something we don’t. As viewers will know, Clarkson’s Farm operates in open countryside in an AONB. As well as agriculture, it has diversified to include a farm shop and a café in a lambing barn. The business tried to open a restaurant in a converted barn located some distance from the shop. The site is obviously used as a filming location. The business has proved popular and it now has significant parking and highway problems. The farm shop (with limited parking) has permission, the construction of the lambing barn (but not its use) has permission and there is permission for limited filming. The council enforced against the material change of use of the land to a mixed agricultural and leisure attraction use, comprising café, restaurant, gift/farm shop, parking and lavatory facilities. The notice was appealed. The appellant also sought (and was refused) permission for additional parking, access, storage and landscaping. This appeal was heard alongside the enforcement appeal. The inspector dealt first with the planning unit. The appellant alleged that there were three separate planning units (shop, café, restaurant), with each having a separate primary use. The council had enforced against a single unit in a mixed use. The inspector took into account that the shop/café was in a different ownership to the farm and that it had its own permission. But its activities clearly spilled out of the permitted area, extending to the proposed restaurant and the wider parking areas. The restaurant used the same parking as the shop. These were fenced/walled off from the remainder of the farm. He concluded that there was a single planning unit. As for the use of that planning unit, the inspector took issue with several items listed by the council. “Gift shop” was too ambiguous; a shop is a shop. Similarly, while visitors no doubt came for the experience, the business was not a “leisure attraction”. A leisure attraction required, said the inspector, something which the customer might be expected to pay for. There was no entrance fee here, just a shop and café. (It appears that the inspector was also concerned that any permission for a “leisure attraction” would create a very wide lawful use.) Nevertheless, there were several primary uses in a single unit so the development was a mixed use, in this case a “mixed use comprising agriculture, café, restaurant, farm shop, parking, lavatory facilities.” This put paid to the ground (b) and (c) challenges. The challenge was that the restaurant was a separate planning unit. As it was in the curtilage of the lawful farm shop, the appellant said that Class R permitted a change of use to a flexible use including a restaurant. In the light of his conclusion on the planning unit, the inspector rejected this. He said he would have rejected the Class R argument anyway as the restaurant was not clearly within the curtilage of the farm shop. The remainder of the uses cited in the notice were also challenged on the grounds that they were ancillary to the lawful farm shop use and not primary uses. The inspector concluded that, as the restaurant resulted in a mixed use, there had been a material change of use so it was irrelevant whether the other items were ancillary. As an aside, viewers of the series will recall the scripted glee with which the appellant came up with the “PD loophole” for his restaurant. It is fitting, therefore, that it was the restaurant which was the primary reason the breach was upheld. The inspector nevertheless looked at the extent to which the various alleged ancillary elements (other than the restaurant) were part of the lawful use prior to the breach. This was relevant to the fallback but also to what the extent of the material change of use truly was. He identified that the question was whether any of the elements represented a change in the character of the use. The inspector found that the level or vehicle traffic and parking went far beyond that for which permission had been given. And that the lambing shed was clearly not “by any stretch of reasonableness” being used for the purpose for which it was given permission. Even the toilet facilities went beyond what would be expected for the permitted farm shop. This was not intensification, it was a material change in the character of the use. The LPA even won the merits arguments on ground (a). The number of visitors, the traffic and parking problems, the outdoor seating, catering van and toilets clearly had an adverse effect on the AONB. The parking and landscaping proposed under the s78 application would have a similar effect. This had great weight. In the end though, permission was granted for the mixed use, including the use of the lambing shed as a café and the enforced against parking and toilets. Permission was granted under the s78 appeal for altered parking, storage and landscaping. Only the restaurant was refused. The inspector found that the parking would alleviate the current parking situation and highway safety even though it would not provide a complete solution. He accepted that a number of local suppliers benefited from trading arrangements with the shop and that the shop contributed to the local economy. He accepted that diversification was to be supported. These considerations also had great weight. Key to the decision, though, was the fact that permission had been granted, not just for a farm shop, but for a celebrity’s farm shop. Even if there was no café or restaurant, the popularity of the appellant was such that people would continue to visit the shop in numbers. This reduced to moderate the harm to the AONB caused by the new elements of the use because the permitted use already resulted in significant harm. The appellant’s celebrity might wane. In which case, the weight of the considerations in favour of the development would wane. The permission granted was therefore time limited to 36 months. The decision is well reasoned and fairly logical. The inspector did not say that the character of the use already permitted varied with the identity of the user. But the result seems to imply that the harms associated with the use could vary and that the LPA had accepted them all in granting permission. Yet it is difficult to think that the LPA could successfully have imposed conditions on the farm shop based on the identity of the applicant. The result is therefore troubling.
