Shepherd's huts and mobile homes on agricultural land

A shepherd's hut on wheels is almost always a caravan in law, and that matters more than whether it looks like a building. Because a caravan is not a building, siting one is not operational development. The planning question is whether putting it on agricultural land, and using it, amounts to a material change of use of that land. In most cases where somebody sleeps in it, the answer is yes, and permission is needed.

When a hut counts as a caravan

Section 29 of the Caravan Sites and Control of Development Act 1960 defines a caravan as any structure designed or adapted for human habitation which is capable of being moved from one place to another, whether by being towed or by being transported on a vehicle or trailer.

A traditional shepherd's hut, built on a chassis with cast iron wheels and fitted out with a bed and a stove, fits that definition comfortably. So does a static caravan and so does a converted horsebox.

Two things take a structure outside the definition. Losing the capacity to be moved is the first, and that happens more easily than owners expect. Removing the wheels, bedding the chassis into a concrete base, building brick skirting around it or connecting it by rigid pipework to a septic tank can all convert a caravan into a building, at which point siting it becomes operational development and a different set of rules applies.

The second is failing the size tests where the structure is made of more than one section.

The statutory definition and its two size tests

Section 13 of the Caravan Sites Act 1968 extends the definition to twin-unit structures composed of not more than two sections, designed to be assembled on site by bolting or similar means, and capable of being moved by road when assembled.

Those twin-unit structures must not exceed 20 metres in length, 6.8 metres in width, or 3.05 metres in internal height measured from floor to ceiling. A structure larger than any of those figures is not a caravan, whatever its wheels suggest.

Single-section structures are not subject to those dimensional limits. The test for them is simply whether the structure is capable of being moved from one place to another, which a hut on a chassis plainly is.

Measure before ordering. Bespoke twin-unit lodges sold for glamping sites sometimes sit close to the width limit, and a unit that exceeds it is a building requiring planning permission for its erection rather than a caravan raising a change of use question.

Whether siting amounts to a change of use

Placing a caravan on land does not, by itself, change the use of that land. What changes the use is what the caravan is used for and how permanently it is there.

A hut stored in a corner of a farmyard, unoccupied, is unlikely to change anything. A hut occupied as living accommodation introduces a residential use onto agricultural land, and that is a material change of use requiring permission. A hut let to holidaymakers introduces a tourism use, which is also material.

Part 5 of Schedule 2 to the General Permitted Development Order 2015 grants rights for the use of land as a caravan site in the circumstances set out in Schedule 1 to the 1960 Act. Those circumstances include use within the curtilage of a dwellinghouse incidental to its enjoyment, seasonal accommodation for agricultural and forestry workers, certificated sites operated by exempted organisations for a small number of units, and limited short-period uses on larger holdings.

Read the exemption you intend to rely on in full. Each carries conditions about numbers, duration and who may occupy, and a use that starts inside one and drifts outside it is unauthorised from the point it drifts.

Use for holiday letting

Holiday use is the most common purpose and the one most likely to need a full application.

The planning case for it is usually rural diversification, and it is often accepted where the siting is well screened, the access works and the number of units is modest. What is assessed is the number and position of units, the parking and access, the effect on the landscape, and the facilities serving them.

Conditions commonly restrict occupancy to holiday use, prevent occupation as a sole or main residence, require a register of occupiers to be kept, and sometimes limit the season. Those conditions are enforceable and lenders treat them as material, so read them before building a business plan around year-round letting.

Where the operation grows to include a reception, a shower block, hardstanding and lighting, it becomes a caravan site rather than a few huts in a field, and the landscape and visual impact assessment will be looking at the whole operation. The wider assessment resembles that for other visitor uses, and the issues set out for farm diversification into events and weddings apply to the traffic and noise questions in the same way.

Use as worker accommodation

Accommodation for an agricultural worker is a different argument with a different evidence base.

National policy allows isolated homes in the countryside where there is an essential need for a rural worker to live permanently at or near their place of work. The evidence is functional and financial: what the enterprise is, why someone must be on site at night, what the labour requirement is, and whether the business is viable and established.

Temporary permission for a caravan while a new enterprise proves itself is a recognised route, usually for three years, with a condition requiring removal if the business fails. That is a reasonable outcome to accept on a new holding.

The seasonal worker exemption in the 1960 Act operates differently again and is limited to accommodation for workers employed in agriculture or forestry on the land. It does not cover a family member's long-term home.

Services, drainage and permanence

The services are what convert a hut from a temporary structure into a fixed one, both physically and in the eyes of an officer.

Keep the connections demountable. Flexible supply pipes and cables, a portable or cassette toilet, or a hookup that can be disconnected preserve the caravan characterisation. A foul connection needs its own thought, and a foul sewage assessment is usually required where a package treatment plant or septic tank is proposed, along with a permit or exemption from the Environment Agency for the discharge.

Hardstanding is the other trap. An area of compacted gravel for a hut base is engineering operations and can itself require permission on agricultural land, quite separately from the hut.

Decking, pergolas, hot tub platforms and fenced enclosures around each hut are the features that turn a modest proposal into a visible installation, and they are frequently what triggers the complaint.

An illustrative example

A smallholder sites three shepherd's huts in a paddock for holiday letting, each on wheels with a cassette toilet and a flexible water feed from a standpipe. Permission is granted for change of use of the paddock, conditioned to three units, holiday occupancy only, no hardstanding beyond a gravel path, and a landscape planting scheme. A fourth hut added two years later without permission is unauthorised. This example is illustrative.

Enforcement risk and how to reduce it

Unauthorised caravan siting is one of the most frequently reported breaches in rural areas, and neighbours report it quickly.

A material change of use that has continued for long enough may become immune from enforcement, and the time limits in England were extended to ten years by the Levelling-up and Regeneration Act 2023, with commencement arrangements that need checking against the date the use began. Relying on immunity means running a business that cannot be sold or refinanced until it is proved.

The lower risk route is the ordinary one:

1. Establish whether the structure meets the caravan definition, measuring the dimensions where it is a twin unit.
2. Check whether any Schedule 1 exemption covers the intended use as described.
3. Where it does not, apply for change of use, with a planning statement setting out the diversification case.
4. Keep the structure and its connections demountable throughout.
5. Where you intend to grow, apply for the number you want rather than adding units annually.
