How does Class Q Permitted Development work?

The procedure has two stages. The first stage is to notify the Council that a change of use is proposed under Class Q (a). The second stage, only possible if the principle has been agreed, is to seek agreement to the actual proposed design and external appearance of the conversion under Class Q (b).

Where do Class Q planning rules not apply?

This prior approval procedure only applies in England and does not apply to areas of Outstanding Natural Beauty (AONB), National Parks and Conservation Areas, listed buildings, scheduled monuments, Sites of Special Scientific Interest (SSSI), safety hazard areas or military explosives storage areas. The new rules do apply to barns in the Green Belt.

Will the converted barn still have to look like an agricultural barn?

The Council can assess the design and external appearance of the existing building. Windows and doors can be added as part of the conversion design.

What does 'barn' really mean? How about redundant grain silos?

It has to be an agricultural building as opposed to a structure used in the farming industry, so silos would most probably get a 'No'.

How easy would it be to get 'ordinary' planning permission for an extension on a barn?

It's possible but not always easy. It would depend on what is proposed; as a rule of thumb the more modest the proposal the better the chance, and this will vary from council to council.

Could the barn be falling down?

It may currently look a mess, but it's the building's basic underlying structure that matters. Its main framework must be sufficiently robust for conversion to a habitable dwelling without the construction of new structural elements. The building does not even have to have full existing foundations or an existing concrete slab base so long as the foundations of the framework itself are in good shape.

What about a site with contamination or flooding?

It is good practice to submit details at stage one to demonstrate there are no concerns and prevent the Council refusing consent due to 'lack of information'. If the barn is in flood zones 2 or 3 you will need to submit a site specific flood risk assessment upfront.

Q: How long does the Class Q approval process take?

The Council only has 56 days to make their decision for Class Q(a). After that it benefits from 'deemed consent' for the conversion and any necessary building works provided they are within the scope of class Q.

Q: Can permission be given to convert separate barns?

Yes, but no more than a total of 10 new Class Q dwellings are allowed on the farm. Open sided barns, such as many Dutch barns, can qualify for converting under the new rules.

Q: Could it be a fairly new barn?

If a building has been constructed and used in farming before 20th March 2013, then an application for a conversion can be made. If the building was constructed after that date, you'd need to wait 10 years before making the application.

Q: If successful, would it affect normal agricultural permitted development?

Exercising Class Q in respect of any building will suspend normal agricultural permitted development rights for a period of ten years from completion. You may wish to ensure you have adequate replacement facilities in place prior to submission.

Convert Farm Buildings Under Class Q Permitted Development

Some farmers are taking advantage of the opportunities that now exist to convert ordinary, often quite modern, agricultural barns and sheds to new dwellings (Class Q) or commercial use (Class R) without planning permission.

Since the 1st of May 2024, far less stringent rules now apply so that as many as 10 new dwellings can be created from former agricultural barns under Class Q. However, it’s all still a bit of a planning jungle which is why it is good to have a qualified chartered town planner on your side who has also worked as a council planning offer, which is what we offer at AFA Planning Consultants.

The increase in value can be very significant when the barns are put on the open housing market or even offered for sale un-converted but with the approvals in place, with one high-end converted Dutch barn was recently on the market for nearly £2 million. Once the principle is approved by the Council a quick and substantial profit can be made by putting the barn on the market in its unconverted state. Class R conversions are often retained to provide a rental income or can be sold unconverted with the Class R in place.

Rules On Barn Conversions For Farm and Agricultural Buildings

Starting from 1st May 2024, you will be able to turn an agricultural barn or shed into up to 10 new homes, with a combined total floor area of up to 1,000 square metres. Each individual home can be as large as 150 square metres, and there is also the option to create a mix of smaller and larger homes within the same building. This gives you more freedom to choose different sizes for the new homes, as well as increasing the total space avaliable compared to the old rules from 2014.

This means that if the circumstances are correct, permitted development (PD) rights exist as to the principle of a barn conversion. The main point about PD here is that that you don’t need to get planning permission as such on the principle, and if the criteria are all met the planning authority (usually the Council) must agree even though they would not have given permission before the new rules came in.

In stage two the Council can only assess the proposal on:

• Transport, highways and noise impact

• Contamination and flooding risks

• Design and external appearance of the existing building

• Whether the location or siting of the building makes it otherwise impractical or undesirable for the building to change from agricultural use to a dwelling

Conversions are likely to get refused if, for example, they are close to un-neighbourly on-going farm operations, such as intensive livestock buildings or noisy machinery such as grain dryers. However rearranging the overall farm layout including demolition in advance could be the way forward as the Council has no control over agricultural operations.

The quick profit option: Some barn owners have simply gone for Prior Approval, Q(a) as per stage one and having got the principle agreed first, have then put the barn on the market leaving it for the new owners to sort out the detailed plan approval as per stage two. This way the new owners can create their own detailed plans and design, plus it gives the barn owner a very quick return. Unconverted barns with only the first stage in place have recently been on the market for £80K and £750K!

Note: If the Council ‘refuse’ any of the above, we can appeal to the Government’s independent Planning Inspectorate.

Where Do These Planning Rules Not Apply?

This prior approval procedure only applies in England and does not apply to areas of Outstanding Natural Beauty (AONB), National Parks and Conservation Areas, where the site is or forms part of a listed building (including curtilage listed buildings), a scheduled monument, a Site of Special Scientific Interest (SSSI), a safety hazard area or a military explosives storage area. So if your barn is in one of these you would need ‘ordinary’ change of use permission.

Note: The new rules do apply to barns and sheds in the Green Belt.

Would This Affect Normal Agricultural Permitted Development Or An Application For A New Agricultural Barn?

Unfortunately, exercising Class Q in respect of any building will suspend normal agricultural permitted development rights for a period of ten years from completion. This is an important consideration and you may wish to ensure you have adequate replacement facilities in place prior to submission of a notification under Class Q.

How Long Does It Take? What If The Council Don’t Make A Decision?

They only have 56 days to make their decision for Class Q(a) after that it benefits from ‘deemed consent’ for the conversion and any necessary building works provided they are within the scope of class Q.

Can Permission be given To Convert Separate Barns?

Yes, but no more than a total of 10 new Class Q dwellings allowed on the farm.

Open sided barns, such as many Dutch barns, can qualify for converting into a barn under the new rules; obviously, the finished item would have the sides filled in as necessary.

Will It Still Have To Look Like An Agricultural Barn? What About Windows And Doors?

The type of areas that are allowed are the installation or replacement of windows, timber windows, doors, roofs, or exterior walls, drainage, electricity, gas or other services, to the extent reasonably necessary for the building to function as a dwelling house as well as partial demolition to the extent reasonably necessary to carry out these building operations.

All of this offers a lot of scope for some significant rebuilding or replacement of the existing fabric such as asbestos cladding although wholesale demolition of the building and its entire replacement would not be allowed. It is unlikely that the new rules can be exploited to create homes out of glasshouses / orangeries although we do know of one such case that has been allowed and another where the ‘barn’ is just an old nissen hut!
‍

Your interior is likely to be a blank canvas opportunity often with lots of space to play with and none of the planning constraints that come with listed buildings or even older farm barns. Whilst the Council are unlikely to be too fussed about what the inside is like, the creation of a new floor is not included and could be a problem unless the barn already has a second floor.

How Detailed Do The Architectural Plans Have To Be?

There don’t have to be any architectural plans at all for stage one, which as we have said makes it a quicker turn around, but obviously they are essential for stage two. Those plans would have to be sufficiently accurate and to scale and show all elevations proposed and existing.

Could It Be A Fairly New Barn?

If a building has been constructed and used in farming before 20th March 2013, then an application for a conversion can be made. If however the building was constructed after that date, then you’d need to wait 10 years before making the application.

Is A Barn Conversion Still Possible At A Remote Or ‘Unsustainable’ Location?

Until recently many councils were refusing prior approvals because the conversions were in ‘undesirable locations’ which the councils took to mean isolated and therefore environmentally unsustainable places due to distance from services. etc. However, the Government has now clarified that ‘undesirable’ and ‘impractical’ has more to do with being difficult to access by road or close to an area where its quality of amenity would be so poor due to adverse environmental effects (i.e. noise, smells etc).

‍So, a remote or isolated location is not now automatically ruled out.

How Small Could The Barn Be To Convert?

There isn’t a lower limit however it must be at least a 1 bed unit otherwise it would be “impractical or undesirable”. It must also have some kind of curtilage and outlook, space for bins, etc.

If Successful Would It Have An Agricultural Occupancy Condition? And What About A Section 106?

Although it is quite rare, some council’s impose agricultural occupancy conditions where they consider it necessary due to such things as the close proximity of other farm building which are still used for animals and this may also be done via a S. 106.

What About Rural Barns That Are Not Agricultural Or Do Not Qualify?

It is still possible to get ‘ordinary’ planning permission to convert other barns in the countryside into homes. The ‘rule of thumb’ is that the barn concerned must be structurally sound and is either of some architectural, historic or landscape merit.

What About Gardens And Parking Space?

Basically this must be no more than the curtilage of the building, which may be quite generous and provide a great garden area and parking.

But if the curtilage is very limited, garden land and parking can be a real problem so again your best plan is to have one of our chartered town planners who really knows the rules to argue your case.

The rules do make some provision for the inclusion of extra land not actually in the building’s curtilage, basically so long as the land is no larger than the area occupied by the building and where that land is immediately beside or around it.

Can The Barns Be Used For Other Uses?

Yes, there are other rules (Class R) which also allow agricultural buildings under 500 sq. m. to change to a flexible commercial use, i.e. A1 (retail), A2 (financial and professional services), A3 (café), B1 (business), B8 (storage and distribution), C1 (hotels) or D2 (assembly and leisure) uses, as well as schools and nurseries. This is subject to meeting similar criteria for conversion to homes for uses over 150 sq. m.

In all cases these agricultural buildings must have been in agricultural use at the 20 March 2013 or in agricultural use when it was last used if before that date.

But again the rules are complex and you are best advised to have one of our chartered town planners on your case.

Final Words Of Advice On Barn Conversions

There is so much more which is why you would need a proper planning consultant on the case. However, here are three final points:

(i) If you are about to sell your farm, remember to factor in the potential value of buildings which could are suitable for a barn conversion. Would you be happy for the new owner to do what you could have done before selling up? Why not get the Class Q(a) approval in place first, then put the farm on the market?

(ii) Don’t start any of the work before the necessary approvals are in place. If you do, you may compromise the ‘agricultural use’ and the Council are likely to say that the new rules don’t apply therefore you need normal full planning permission which is a more onerous process altogether indeed one which is extremely unlikely to succeed for a modern agricultural building.

(iii) If your conversion relates to a building that originally had planning permission, check that permission for any restrictive conditions. For example there may be a condition which states that the building can only be used for agricultural purposes or preventing other uses such as dwellings. If this is the case you may need to get that lifted before going for the prior approval.
