Planning permission for caravan storage on farmland

Parking caravans on a field is a material change of use, so caravan storage planning permission on a farm is needed even where nothing is built and the surface stays as grass. Agricultural permitted development rights cover buildings and works reasonably necessary for agriculture, and storing other people's touring caravans and motorhomes is not agriculture. In the Green Belt the application then turns on openness rather than on whether the caravans can be screened, which is a harder test than most applicants expect.

Why storage is a material change of use of agricultural land

The definition of development includes a material change in the use of land, and using a field to store vehicles for other people is a change from agriculture to storage. It does not matter that the caravans are movable, that the field is still grazed in summer, or that the business is small.

Two rights are sometimes cited and neither helps much. The temporary use right in the permitted development order allows land to be used for any purpose for a limited number of days in a calendar year, which suits an event rather than a storage business operating through the winter. And the agricultural rights in Part 6 apply to development reasonably necessary for the purposes of agriculture on an agricultural unit, which a commercial storage compound is not.

Site licensing is a separate question again. The caravan site licensing regime is concerned with caravans used for human habitation, so storing unoccupied units does not usually engage it. That is helpful to know and it is not a planning permission.

Where farm diversification policy in the adopted plan supports the reuse of land and buildings for rural enterprise, storage of this kind often fits well, particularly where it uses an existing yard or a redundant building rather than open field. Say so in the planning statement and cite the policy by number.

Surfacing, drainage and run-off from hardstanding

The surface decides how the application is assessed. Storage on grass with no works is a change of use alone. Laying hardcore, concrete or a permeable grid is an engineering operation as well, and it usually pushes the scheme into needing a drainage strategy.

Set out the build-up in section with thicknesses, say whether the surface is permeable, and calculate where the run-off goes. Where a sealed surface is proposed, attenuation and a discharge route have to be shown, and an infiltration feature needs field testing rather than an assumption.

Choose the surface with an eye on the landscape as well as the drainage. A reinforced grass or gravel matrix that stays green reads far better in open countryside than a black tarmac apron, and it keeps the restoration case simple.

Contamination is a live issue with older vehicles: oil drips, waste tank discharge and battery storage all belong in the management arrangements, and a chemical toilet disposal point needs a proper connection rather than a soakaway.

Green Belt openness and rural character

In the Green Belt, the analysis is about openness, which has spatial and visual aspects. A field containing sixty caravans is less open than an empty field, whatever hedge is planted around it, so screening is an argument about visual impact rather than an answer to the openness point.

That normally makes the proposal inappropriate development, which can only be approved where very special circumstances clearly outweigh the harm. Those circumstances have to be more than the applicant's wish to diversify. Genuine arguments include the absence of alternative sites, the removal of caravans from residential streets where the council has a stated problem, the temporary and reversible nature of the use, and a restoration obligation.

Outside the Green Belt the test is character and appearance rather than openness, and the same scheme becomes much more arguable. Look at the landscape character assessment for the area, site the compound against existing built form or woodland rather than in the middle of a field, and keep the stacking low and the rows aligned so the visual mass is broken.

Best and most versatile agricultural land adds a further objection. Where the field is graded in the higher categories, permanent hardstanding removes it from production, and a reversible surface with a restoration condition is the answer worth offering.

Access, gates and visibility on a country lane

Highway officers treat these applications as generating slow, wide vehicles turning off a rural road, and the visibility case is the part most often underprepared.

Provide a drawing with visibility splays dimensioned to the standard appropriate to the recorded vehicle speeds on the lane rather than to the speed limit, showing what vegetation has to be cut back and confirming that the land within the splay is controlled by the applicant. Show the access width and the internal geometry, proved by vehicle tracking for a four by four towing a twin axle caravan.

Set the gates back far enough from the carriageway that a towing vehicle can wait clear of the road while they are opened, and show the turning area inside. Access movements are seasonal and concentrated, with peaks at Easter, bank holidays and the start and end of the season, so describe that pattern rather than quoting an annual average. The same reasoning about intermittent rural trip generation applies to other roadside enterprises, as the note on a mobile catering unit on private land sets out.

Security lighting and its limits in dark landscapes

Storage compounds want lighting and dark rural landscapes cannot absorb it. Treat the two as a design problem rather than a specification to be added later.

Rural sites usually fall into one of the darker environmental zones used in obtrusive light guidance, with tight limits on light spilling onto neighbouring windows, on the intensity of a luminaire as seen from a receptor, and on upward light, tightening further after a curfew hour set by the council.

Design accordingly. Low mounting heights, full cut-off optics with no upward component, presence detection with a short over-run rather than dusk to dawn operation, and a switch-off time. Where security is the concern, a camera system with infrared illumination and a monitored alarm does the job without lighting the field, and it is worth saying that in the application because it removes the officer's main objection.

Seasonal occupancy and the risk of residential use

Councils are alert to storage compounds becoming something else. A caravan that is occupied, even occasionally, changes the use, and an unauthorised residential use on agricultural land is a difficult enforcement problem the authority would rather prevent.

Address it directly. Confirm that no unit will be occupied, that no services will be connected to individual pitches, that there will be no washrooms or facilities capable of supporting occupation, and that the operator keeps a register of stored units with owner details.

Offer the condition yourself. A clearly worded restriction prohibiting occupation or residential use, and prohibiting the siting of any caravan for human habitation, is easier to live with than a refusal, and it makes the difference on marginal applications. The distinction between storage and occupation is the same one that runs through applications for an electric vehicle charging hub and other rural commercial uses, where the description of the use has to match what will actually happen.

Conditions, restoration and temporary permissions

Expect the following, and consider offering them.

• A maximum number of units, with the storage area defined on an approved plan and no storage outside it.
• A restriction on the height of stacking and on the siting of units against the most sensitive boundary.
• No repairs, servicing, sales or hire from the site, since each of those is a separate use.
• Surfacing as approved, with any change requiring consent.
• Hours during which the site may be accessed.
• External lighting only as approved, with a switch-off time.
• Landscaping planted in the first planting season and replaced if it fails.
• Restoration of the land to agricultural condition within a stated period if the use ceases.

A temporary permission of three or five years is often the way through on a contested site. It lets the council see the impact before committing, and a well run site with no complaints is in a strong position when the renewal comes. Ask for it rather than waiting to be offered it, and make sure the restoration condition is drafted so the obligation survives the expiry.
