Woodland and forestry buildings: permitted development

The forestry permitted development building rights sit in Schedule 2 Part 6 of the GPDO 2015, in Class E, and they are separate from the agricultural rights most rural owners know. Class E permits development on land used for forestry, including afforestation, where it is reasonably necessary for those purposes: erecting, extending or altering a building, forming or altering a private way, winning materials on the land for those works, and other operations short of engineering or mining. What it does not permit is a dwelling, and that single exclusion accounts for most of the disappointment.

Forestry rights are not agricultural rights

Part 6 contains separate classes. Classes A and B cover agricultural development on holdings of five hectares or more and under five hectares respectively, each with its own size, height and siting limits. Class E covers forestry, and it does not carry the five hectare distinction at all.

The threshold question is whether the land is used for forestry. That is a matter of fact rather than intention, and a woodland managed under a written management plan, with thinning and felling carried out under licence and timber sold, will satisfy it. A few hundred trees planted in a paddock three years ago will not, however genuine the ambition. Evidence that carries weight includes a forest management plan, felling licences, grant agreements, contractor invoices and a record of timber sales.

Where a holding includes both farmland and woodland, the classes apply to the land in each use, and the same building cannot draw on both. A machinery store serving the arable enterprise is agricultural development on the agricultural unit. A store for forestry machinery on the woodland is Class E development. Trying to justify one building under both tends to produce a refusal of the prior notification under each.

Buildings reasonably necessary for forestry

Class E permits a building where it is reasonably necessary for the purposes of forestry on that land. The test is functional, so the application needs to explain the operation the building serves.

Buildings that ordinarily satisfy it include machinery and implement stores, a workshop for maintaining forestry plant, a timber store, a welfare and mess facility for the workforce, and a store for fuel and consumables.

Limits apply to all of it. The height of any building or works must not exceed 12 metres, reduced to three metres where the development is within three kilometres of the perimeter of an aerodrome. No part of the development may be within 25 metres of the metalled part of a trunk or classified road. And the right does not extend to providing or altering a dwelling.

Read the Order for the restrictions that apply on designated land, because National Parks, the Broads, National Landscapes and conservation areas attract additional constraints within Part 6, and those restrictions are the ones most often overlooked on the sites where woodland tends to be.

Prior notification and what to send

Where the development is the erection, extension or alteration of a building, or the formation or alteration of a private way, you must apply to the local planning authority for a determination as to whether its prior approval is required. For a building, the matters are siting, design and external appearance. For a private way, they are siting and means of construction.

The application needs a written description of the proposed development, a plan indicating the site, and the fee. The authority has 28 days, which is shorter than the period for the residential conversion classes and easy to misremember.

Three outcomes follow. The authority may determine that prior approval is not required, in which case you proceed in accordance with the details submitted. It may determine that approval is required and then grant it, with or without conditions on those matters. Or it may not notify you within 28 days, in which case you may proceed in accordance with the submitted details.

Make the submitted details good enough to build from, because in two of those three outcomes they become the specification. A sketch plan with no elevations creates an argument later about whether what was built matches what was notified.

Development under Class E must begin within five years of the determination, and must be carried out in accordance with the approved details where approval was given.

Dwellings and residential use

Class E cannot provide a dwelling, and the exclusion is read strictly. A mess room with a shower is a welfare facility. The same building with a bedroom and a kitchen is a dwelling by another name, and an enforcement officer will treat it as one.

A forestry worker's dwelling therefore needs full planning permission, assessed against rural workers' dwelling policy. The tests are functional need, meaning a demonstrated requirement for a worker to live at or close to the place of work, and financial viability of the enterprise supporting it. Both need evidence: labour requirement calculations, accounts, a business plan and a management plan. A temporary permission for a caravan for a trial period is a route some authorities accept while the enterprise establishes itself.

Where accommodation is the objective rather than forestry operations, be honest about that at the outset. A planning statement that sets out the functional need case properly will do more than a Class E notification that later has to be abandoned.

Access tracks serving woodland

Forming or altering a private way within the woodland is within Class E, subject to prior notification. Getting onto the public highway is a separate matter.

Part 2 of Schedule 2 permits the formation of an access to a highway where it is required in connection with development permitted by another class of the Order, except where the highway is a trunk road or a classified road. So a new access onto an unclassified lane in connection with permitted forestry development is covered. A new access onto a classified road is not, and needs planning permission plus the highway authority's own consent for works in the highway.

Two practical constraints on the track itself. Where the track requires materials, Class E permits winning them on the land for the purpose, which is the provision that makes a borrow pit lawful in limited circumstances, and the interaction with minerals policy is worth checking where mineral safeguarding applies to the land. And where the access or the track requires the removal of hedgerow, the notice requirements apply independently of the planning position, as set out in hedgerow removal notices and the important hedgerow test.

Also check whether the forestry regulator's own environmental assessment regime applies. Afforestation, deforestation, forest roads and forest quarries above the relevant thresholds require consent from the forestry authority under the forestry environmental assessment regulations, which is a separate consent from anything the planning authority issues.

Felling, protected trees and designations

Felling is regulated by the Forestry Act 1967 and normally requires a felling licence from the forestry authority. The usual exemption allows a limited volume in any calendar quarter, with a smaller limit on what may be sold, so routine management stays outside the licensing system while any commercial operation does not. Check the current volumes on the regulator's guidance, because they are the figures that determine whether you need a licence rather than a rule of thumb.

Three overlays sit on top.

A tree preservation order, which requires separate consent for works to protected trees. The forestry exemptions within the tree protection regime are narrow and turn on whether a felling licence or an approved plan of operations covers the work.

Ancient woodland, which national policy treats as an irreplaceable habitat with a very high bar against loss or deterioration, and which constrains track routes as much as felling.

Protected species, which are dealt with under wildlife legislation regardless of any permitted development right. Bat roosts in mature trees and badger setts in woodland banks are the common ones.

When a full application becomes necessary

Class E runs out at predictable points, and recognising them early saves a wasted notification.

A dwelling of any kind, including a mobile home used residentially. A building over 12 metres, or over three metres near an aerodrome. Anything within 25 metres of a trunk or classified road. Engineering or mining operations beyond winning materials for the permitted works.

Then there are the uses that go beyond forestry itself. A sawmill processing timber brought in from elsewhere is an industrial use. A woodfuel operation supplying customers off the holding is likely to be a separate commercial use. Visitor facilities, car parking for recreation, camping pitches, a shop and an events barn all sit outside Class E, and the route for those is the same as for any other rural enterprise, along the lines described in farm diversification into workshops and offices.

An illustrative example. A 45 hectare mixed woodland with an active management plan, a felling licence in place and one contractor. The owner notified a 180 m² machinery store and mess building at 5.5 metres to ridge, positioned 60 metres inside the wood off an existing track, with elevations in dark stained timber and a plan showing the track upgrade. The authority determined that prior approval was required, approved it on siting and external appearance with a condition on the cladding finish, and the building went up the following spring. A second proposal for a two-bedroom unit above the store was withdrawn and pursued as a full application on functional need grounds.

Notify the building first, and keep the dwelling question entirely separate.
