Prior Approval consents- be aware

Izindi Visagie • 25 November 2020

Beware the limitations and conditions of ‘Prior Approval’ consents

There is a common misconception that, for enforcement purposes, planning decisions in relation to the application of Prior Approval are interpreted in the same way as other planning permissions granted by an LPA, i.e. that all terms and conditions are contained within the four corners of the decision notice. Not so for Prior Approval consents.

Prior Approval is not a permission in itself. The permission is contained in the GPDO. The GPDO makes it a condition of the permission that Prior Approval is obtained (or confirmed not necessary as appropriate). The act of securing a Prior Approval consent is effectively a discharge of a pre-commencement condition. To be lawful, the development must still comply with the relevant terms and conditions of the GPDO. Granting of Prior Approval does not necessarily mean that the development complies with the GPDO. If it doesn’t comply, it doesn’t comply and granting prior approval does not alter that. Granting Prior Approval simply means that the condition is satisfied.

One important limitation in the GPDO is Article 3(5) which provides that, irrespective of whether it meets the requirements in the various parts of Schedule 2 or 3 etc, development is not PD where: 

 “in the case of permission granted in connection with an existing building, the building operations involved in the construction of that building are unlawful” 

This limitation is tested at the time of carrying out the development, not at the time of securing the Prior Approval consent. 

The application of Article 3(5) took centre stage in the recent High Court case of RSBS Developments Limited v SoS HCLG & Brent [2020] EWHC 3077 (Admin)

The history

In June 2015 RSBS applied to the Council for a determination as to whether its Prior Approval would be required for the change of use of the premises from office use to 16 flats. In August 2015 the Council issued a decision notice confirming that Prior Approval was required and Prior Approval consent was granted. Works commenced in September 2015. 

In November 2015 RSBS applied for and was granted planning permission for a first floor extension. An informative made clear the permission could not be implemented in conjunction with the works in the prior approval application. 

However, between December 2015 and February 2016 an altogether new extension was built, increasing the building by 4% in overall size.

The Planning Inspector determined that on the facts the change of use from office to residential use took place between mid-February 2016 and 18 June 2016. The conversion differed from the layout plans submitted with the prior approval application in a number of respects. 

After enforcement investigations RSBS reduced the size of the new extension to approximately its original size and in July 2017 applied for retrospective planning permission to retain the extension. The Council refused permission. 

In November 2017 RSBS applied for a certificate of lawfulness for existing residential use of some of the flats. This application was refused in February 2018. 

The Council then issued an enforcement notice against the use of the property as 16 flats in March 2019. 

The Appeals

On appeal, the Inspector dismissed an appeal against the enforcement notice appeal, an appeal against the refusal of the certificate of lawfulness and an appeal against the refusal of permission for retention of the extension. 

The Inspector found that as the unauthorised extension had been in “shell” form before the material change of use from office to residential took place, the change of use could not benefit from permitted development rights afforded by the GPDO due to the operation of Article 3(5). She also found that the change of use was unlawful because the development undertaken was substantially different to that permitted, such that the 2015 prior approval had not been implemented. 

The works to reduce the extension in size could also not implement the Prior Approval consent or retrospectively render the change of use permitted development. As at the time of completion of the development, it was not permitted development and no future alteration could change that.

At appeal, the Inspector distinguished this case from R (Orange PCS) v Islington LBC [2006] EWCA Civ 157; [2006] JPL 1309 in which subsequent Conservation Area designation was determined not to remove a developer’s rights to build out a Prior Approval permission secured prior to the designation. 

As it happens, in August 2017 the Council introduced an Article 4 GDPO direction removing permitted development rights for the conversion of office buildings to residential use. 

High Court consideration

In the High Court Mrs Justice Lang dealt with the various grounds of challenge: 

Ground 1: RSBS submitted that Article 3(5) of the GPDO was a prospective provision only. [explain relevance] Lang J however agreed with the Inspector that Article 3(5) prevented the development from being permitted development even though prior approval had been granted. 
Ground 2: RSBS submitted that Article 3(5)(a) of the GPDO did not apply in this case because it was concerned with buildings, whereas the development in this case was a change of use. The Inspector had determined that the development was ‘in connection with a building’ and therefore Article 3(5)(a) applies. Lang J agreed the Inspector’s reasoning was correct. 
Ground 3: RSBS claimed that since the offending extension had been reduced in size, the prior approval consent should be retrospectively implemented. The Inspector found that the building works (even the reduced version) were all unauthorised and as such article 3(5)(a) would still be engaged. The Inspector also said that even if she granted permission for the s78 scheme (the operational development), it would still not have the effect of implementing the permission that crystallised with the 2015 approval. Again, Lang J agreed that the inspector’s reasoning was sound. 

Costs were ordered against RSBS and subsequently RSBS was denied permission to appeal. 

The upshot is that the enforcement notice stands and RSBS will need to cease the use of the premises as 16 flats and remove all fittings and fixtures associated with the use of the premises as dwellings. 

Comment
The decision is a welcome confirmation of principles relating to Article 3(5). The judgment confirmed that the time for testing compliance of new development with the GPDO was the time of the development. As such, it confirmed that, if the existing building was unlawful and Article 3(5) applied, the new development would not be permitted development. It confirmed that no subsequent regularisation of the existing building would alter the fact that the new development was not permitted development. It confirmed that the fact that prior approval was granted was not determinative of whether new development complied with the GPDO in all respects. And it confirmed that Article 3(5) applies to use changes as much as operational development.  

But it also goes to show that, when considering enforcement, it is necessary to delve deeply into past planning decisions. The grant of prior approval is not a complete guide to whether past development was lawful. It also suggests that planners should be careful to include informatives if a development is thought not to comply with the GPDO despite the prior approval aspects being satisfied.

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.
