Article 4 directions removing agricultural permitted development

An Article 4 direction removing agricultural permitted development withdraws the rights in Part 6 of Schedule 2 to the General Permitted Development Order 2015 across a defined area, so a farm building that would otherwise have gone ahead on a prior approval notification needs a full planning application instead. The rights themselves are unchanged elsewhere. What changes is the procedure, the range of considerations the authority can weigh, and the amount of design work you have to do before anything is built.

The fee position is the one piece of good news, and it is routinely missed.

Why an authority withdraws Part 6 rights

Part 6 is generous by design. On an agricultural unit of five hectares or more it permits buildings and engineering operations reasonably necessary for agriculture, subject to limits on ground area, height, proximity to roads and, for livestock and slurry, proximity to protected buildings. A prior approval notification covers siting, design and external appearance, and the authority has a short window to respond.

That works well on a large lowland holding. It works badly in an open upland landscape where a 1,000 m² steel-framed building appears on a skyline, or in a valley where the cumulative effect of several holdings each exercising their rights changes the character of the place.

Authorities withdraw the rights where the design and siting control available through prior approval is not enough. National policy expects directions to be limited to what is necessary to protect local amenity or the wellbeing of the area, and to cover the smallest area that achieves it, so a direction over an entire district is unusual and a direction over a specific valley or ridge is not.

Where these directions are most common

National Park authorities are the most frequent users, followed by authorities with large areas of National Landscape. Conservation areas that include farmsteads, the settings of scheduled monuments and registered parks, and open landscapes with long views are the other recurring contexts.

Two points follow for anyone buying or expanding a holding. First, coverage is patchy and local. A neighbouring parish may be unaffected while yours is covered, and the boundary usually follows a landscape feature rather than an administrative line. Second, directions can be made quickly where the authority considers there is an immediate threat, using the procedure that allows a direction to take effect straight away subject to confirmation within a set period.

Directions are not permanent by nature. They can be cancelled or modified by the authority that made them, and a direction made 25 years ago for a reason that no longer applies is a fair subject for a request to review. The wider point about constraints that lapse, expire or are revoked applies here as much as to any other designation.

Checking whether a holding is covered

Do not rely on a single source. Four checks between them give a reliable answer.

1. The local land charges register, which is where a direction is formally registered and where a conveyancing search will find it.
2. The authority's policies map and constraints layer, which usually shows Article 4 areas as a shaded overlay with a reference number.
3. The national planning data platform, which publishes Article 4 direction datasets supplied by authorities, useful for a first look and incomplete in places.
4. A written enquiry to the authority naming the holding, the field parcel numbers and the classes you intend to rely on.

Make the written enquiry even when the mapping looks clear. Directions are drafted in words, and the words decide the scope. A direction may withdraw the whole of Part 6, or only Class A, or only buildings above a stated size, or only development within a defined distance of a road. Two directions in adjoining authorities rarely use the same wording.

Keep the reply. Where the answer is ambiguous, it is evidence of the position you reasonably held.

Applying for permission, and the fee position

Where an Article 4 direction removes permitted development rights, an application for planning permission is required for the development that the rights would have covered. No planning fee is payable for an application made necessary solely by an Article 4 direction. The same applies where the rights were removed by a condition on an earlier permission.

That is worth knowing because authorities occasionally invoice for it in error, and because on a large agricultural building the fee saved is not trivial.

Compensation is the other consequence. Where permission is refused, or granted subject to conditions, for development that would have been permitted but for the direction, compensation may be payable under the compensation provisions of the Town and Country Planning Act 1990. The important qualification is timing: where the authority gives at least 12 months notice before the direction takes effect, compensation is excluded. Most authorities now do exactly that, which is why claims are rarer than the statutory right suggests. The position where rights are removed from houses rather than farms works the same way, and the compensation rules following an Article 4 direction are worth reading alongside this.

Design expectations for farm buildings

An application under a direction is judged on its planning merits, which means the design conversation becomes real rather than procedural.

What authorities in protected landscapes ask for is consistent:

• Siting against an existing group of buildings or a landform rather than in open ground, with the reasoning explained
• Roof pitch and ridge height matched to the existing farmstead, and eaves kept as low as the function allows
• Muted colours, typically dark greens, greys and browns for sheeting, with timber boarding where it suits the setting
• Cut and fill kept to a minimum, with levels drawings showing the result
• Hard standing, access tracks and lighting shown and justified, since these often have more landscape effect than the building
• Native planting used to integrate rather than to screen, because a hedge planted in front of a large shed reads as an apology

For a building in a sensitive landscape the authority may ask for a landscape and visual impact assessment with photomontages from agreed viewpoints. Ask at pre-application whether one is expected and from where, since agreeing viewpoints in advance avoids repeating the work.

What happens to the prior approval route

The prior approval procedure in Part 6 is a function of the permitted development right. Remove the right, and there is nothing to notify. Submitting a prior approval notification for development covered by a direction produces a return of the notification rather than a determination, and the time is lost.

The substantive difference is in scope. Prior approval under Part 6 limits the authority to siting, design and external appearance, or to siting and means of construction for a private way. A full application opens everything: landscape effect, highway safety, residential amenity, drainage, ecology, heritage and the effect on public rights of way. Expect a validation list requiring drawings to scale, a location plan, and in most cases a short planning statement explaining agricultural need.

Agricultural need is the argument to make properly. Set out the herd or flock numbers, the existing building capacity, the reason the new building is needed and why it has to be in that location. An authority that can see the functional case will engage with siting. One that cannot will treat the proposal as speculative.

Confirming lawfulness before you build

Where the position is unclear, whether because the direction wording is ambiguous or because the holding straddles a boundary, a lawful development certificate under section 192 of the Town and Country Planning Act 1990 is the only formal way to confirm that proposed works are lawful. It carries a fee, it is determined on the facts and the law rather than on planning merits, and a positive certificate is binding on the authority.

Building first and asking afterwards is a poor strategy in a protected landscape. Enforcement in these areas is usually active, and an unauthorised agricultural building in a National Park is among the more likely things to attract a notice.
