Equestrian arena and stables in a National Landscape

An equestrian arena and stable block in a National Landscape is a full planning application, not an agricultural notification, and the reason catches out most owners. Keeping and riding horses for recreation is not agriculture in planning terms, so the agricultural permitted development rights in Part 6 of the General Permitted Development Order do not apply, and both the buildings and the change of use of the land need permission. What follows is an illustrative walkthrough of an equestrian arena planning application on a 4 hectare paddock inside a National Landscape, based on the way these schemes are normally assessed rather than on any real site.

The illustrative applicant keeps four horses, wants a 20 by 40 metre sand and fibre arena, a four-box timber stable block with a tack room, and lighting to allow riding on winter evenings.

Why equestrian use is not agriculture

Agriculture, as defined in the Town and Country Planning Act 1990, covers grazing land used in connection with farming. Grazing horses kept for sport or recreation has long been treated as a separate, non-agricultural use, and the consequence is practical: no prior notification route, no 465 square metre agricultural building allowance, and a change of use of the paddock to be described in the application.

So the description of development on the form covers three things at once: the change of use of land to equestrian, the erection of the stable block, and the formation of the arena with associated lighting. Underdescribing it is the commonest validation failure on these applications, because officers cannot condition what the description does not include.

Commercial livery, riding lessons and competition use are different again, with their own traffic and noise implications. The illustrative scheme is private use by the household, and the application says so, because that is what the conditions will be tied to.

Siting the arena within the landform

National Landscape status brings a statutory duty. Public bodies must seek to further the purposes of conserving and enhancing natural beauty, a duty strengthened by the Levelling-up and Regeneration Act 2023, and the National Planning Policy Framework gives great weight to conserving landscape beauty in these areas. In decision terms, that means siting is the argument you win or lose.

The illustrative site slopes gently from a lane down to a stream. Three options were tested: the flat top of the field beside the lane, the mid-slope, and the lower corner beside an existing hedge and barn group. The lower corner won, for reasons that read well in a statement:

• the arena sits below the skyline, so the fencing is seen against the hedge rather than against open sky
• cut and fill balances on site, with a maximum 600 millimetre cut into the slope
• the stable block joins the existing barn group instead of forming a new built element in open field
• the hedge on two sides gives immediate screening without new planting

A level arena on sloping ground needs retaining, and the drawings should show the levels honestly. Officers look for cut and fill sections, because an arena that appears to sit lightly in plan can involve a metre of made ground once the platform is level.

Surfacing, drainage and run-off

An arena is an engineered structure: a subgrade, a permeable membrane, a drainage layer with perforated pipes, and a sand and fibre riding surface. It sheds water differently from grass, so the application needs to say where that water goes.

The illustrative scheme discharges to a filter drain and a soakaway inside the paddock, with an overflow to a shallow swale that runs to a wet grassland corner rather than direct to the stream. That matters where a watercourse is close, because an unfiltered discharge carrying fibre and manure particles becomes an Environment Agency issue rather than a planning one. Manure storage is the other half of it: a bunded, covered midden away from the watercourse, with a stated collection arrangement.

Where a site lies in Flood Zone 2 or 3 or is one hectare or more, a flood risk assessment comes into play as well, and that is worth checking on the Environment Agency flood map before the design is fixed.

Lighting and dark skies

Lighting is where these applications most often fail. National Landscapes are usually treated as environmental zone E1 or E2 under Institution of Lighting Professionals guidance note GN01, the darkest categories, which set tight limits on upward light and on vertical illuminance at windows, with stricter limits after a curfew time the council specifies.

The illustrative scheme uses four columns at 4 metres rather than two at 8 metres, with flat glass, fully shielded luminaires, warm colour temperature and no upward tilt. Hours are offered as a condition: use until 20:00 in winter, no use on Sundays, and a manual switch with no override timer. Offering the restriction is better than defending floodlights at appeal, and the officer can then rely on it.

An illustrative worked point on the lighting calculation: the assessment should report maximum vertical illuminance at the nearest residential window and the upward light ratio for the scheme as designed, not as a generic product specification. Those are the two numbers a consultee checks.

Landscape and visual assessment scope

A scheme this size does not need a full landscape and visual impact assessment to the Landscape Institute methodology. It needs a proportionate landscape and visual appraisal: the landscape character assessment for the area, the sensitivity of the receptors, four to six representative viewpoints including a public right of way and the lane, and a night-time view.

Photographs taken in winter, with the hedges bare, carry more weight than summer ones. If your appraisal only shows July, expect the objection to arrive with a January photograph attached. The approach we set out in the walkthrough for stables and a manege in the Green Belt applies here too, with the landscape test replacing the openness test.

Access, parking and horsebox movements

Private use generates little traffic, and the honest statement of that is usually enough. What the highway authority cares about is the access geometry for a horsebox or a trailer: the turning radius at the field gate, the visibility along the lane, and a hardstanding inside the gate so that a vehicle is not left on the carriageway while the gate is opened.

Set back the gate, keep the surfacing permeable, and show a swept path for the largest vehicle you actually use. If the lane is single track with passing places, say how often movements occur rather than leaving the officer to imagine a lorry a day.

The submitted pack

The illustrative application was submitted with:

1. Location plan, block plan and site sections showing cut and fill.
2. Elevations and floor plan of the stable block, with materials and finishes stated.
3. A planning statement covering the non-agricultural use, the landscape duty and the case for the siting chosen.
4. A landscape and visual appraisal with winter viewpoints and a night-time view.
5. A lighting assessment with an isolux plot, the upward light ratio and proposed hours.
6. A drainage note with the arena build-up, the soakaway calculation and the manure storage arrangement.
7. An ecology appraisal covering the hedge, the stream corridor and biodiversity net gain, prepared by a suitably qualified ecologist.
8. A transport note with the swept path and a statement of vehicle movements.

Biodiversity net gain applies to most new planning permissions, and the statutory metric has to be completed by a competent person, so that part of the pack is not a drafting exercise. The report types by category page shows which of these documents PlanScope can draft and which need a professional author.

Conditions to expect

Conditions on these permissions tend to cover lighting hours and specification, a restriction to private rather than commercial use, no external speakers, a landscape and hedge management plan with a five year establishment period, surfacing materials, and the removal of the arena and restoration of the land if the equestrian use ceases. Read the drafts before they are issued. A condition limiting use to daylight hours, agreed casually, is harder to vary later than one specifying 20:00.
