Documents for a scheme in a National Landscape

National landscape planning documents start from a different baseline than the same scheme would elsewhere. Development inside a National Landscape, the designation that replaced the term Area of Outstanding Natural Beauty, has to show that landscape and scenic beauty are conserved and where possible enhanced, and that means landscape and visual evidence, a lighting response, a materials and detailing schedule and ecology information, even on applications that would be straightforward outside the boundary.

The designation does not prohibit development. It changes the weight given to landscape effects, and it changes what the council expects to read before it can grant.

What the designation changes

Public bodies, including local planning authorities, carry a duty under section 85 of the Countryside and Rights of Way Act 2000 in relation to the purpose of conserving and enhancing natural beauty. The Levelling-up and Regeneration Act 2023 strengthened that duty to one of seeking to further the purpose, and you should check the current wording and commencement position before relying on the formulation in an application.

National policy gives great weight to conserving landscape and scenic beauty in National Landscapes and National Parks. The NPPF (August 2026 edition) also applies a stricter test to major development in designated areas, which is dealt with below. Cite the edition when you quote it.

In practice three things change on the ground. The council will consult the National Landscape partnership or unit, whose comments carry real weight even though it is not a statutory consultee. The management plan for the designated area becomes a material consideration. And design details that would be conditioned elsewhere are often expected up front.

Landscape and visual evidence

This is the centre of the application. A landscape and visual impact assessment prepared to the third edition of the landscape and visual assessment guidelines should cover landscape character at the relevant scale, the special qualities identified in the management plan, visual receptors including public rights of way and open access land, and effects during construction as well as in operation.

Agree the viewpoints with the council and the National Landscape unit before the photography is done. Viewpoints chosen by the applicant alone are the single most common reason a landscape chapter is reopened late in determination, and winter photography from the same positions is frequently requested on tree-screened sites.

For smaller proposals a proportionate assessment is acceptable, and a landscape statement with annotated photographs and a landscape strategy covering planting, boundary treatments and the long-term management regime will often do. Councils usually expect a suitably qualified author for landscape work, and professional review is strongly advised.

Dark skies and lighting material

Several National Landscapes have dark sky status or an explicit dark skies policy, and lighting is where rural applications most often come unstuck.

A lighting assessment should state the environmental zone assumed, usually one of the darker zones in the Institution of Lighting Professionals guidance, and demonstrate upward light ratio, luminaire intensity and vertical illuminance within the limits for that zone. Then design to need rather than convenience:

• Lighting only where a task requires it, with nothing decorative
• Warm colour temperature, commonly specified at 3000K or lower in dark sky areas
• Full cut-off luminaires mounted horizontally, with no uplighting of buildings or trees
• Movement sensors and a curfew rather than dusk-to-dawn operation
• No illuminated signage, and internal blinds where large glazed elevations would spill light

Say what will be dark. An application that proposes no external lighting at all, and accepts a condition preventing it, removes an objection entirely.

Design and materials information

Expect to submit more detail than you would elsewhere. Elevations at a scale that shows the detail, a materials schedule naming products rather than generic descriptions, window and door sections, roof detailing, and rainwater goods specification.

Local materials practice matters. Where the area has a tradition of a particular stone, slate or render finish, the design should engage with it rather than reach for a national housebuilder palette. A materials sample panel on site, secured by condition, is normal.

Massing and siting carry more weight than finish. A building tucked against existing built form or landform, with a ridge line below the skyline from the main receptors, will survive scrutiny that no amount of good detailing can rescue on an exposed knoll.

The major development test in designated areas

Where the proposal is major development in a National Landscape, national policy says permission should be refused other than in exceptional circumstances and where it is in the public interest. The assessment the council needs covers the need for the development, the cost of and scope for developing elsewhere outside the designated area or meeting the need another way, and any detrimental effect on the environment, the landscape and recreational opportunities, along with the extent to which that could be moderated.

Two practical points. Whether a proposal is major development for this purpose is a planning judgement rather than a mechanical application of the statutory definition of major development, so argue it rather than assume it. And the alternative sites assessment has to be real: a one-paragraph dismissal of land outside the boundary will not satisfy an authority that knows the area.

Set that case out in the planning statement with the three limbs addressed in order and the evidence for each attached. The pattern of evidence resembles the bundle described in our note on documents for a scheme in a Source Protection Zone, where a designation drives the document list rather than the scale of the works.

Ecology and hedgerow evidence

Rural sites in designated areas usually carry more ecological interest than the applicant expects. A preliminary ecological appraisal is the starting point, and it will often recommend further survey work with seasonal constraints attached: bat emergence surveys between May and September, great crested newt work in the spring window, reptile surveys from April to October.

Hedgerows deserve separate attention. Removal of a countryside hedgerow may need notification under the Hedgerows Regulations 1997, and the criteria for an important hedgerow include historic and species-related tests that a site walkover can assess. Keep the hedgerow survey separate from the tree survey, because they ask different questions.

Biodiversity net gain applies here as elsewhere, and the statutory metric has to be completed by a competent person under the Environment Act 2021 regime. Protected species survey work and any mitigation licence require a suitably licensed ecologist, and PlanScope's draft is a starting point for that ecologist rather than a substitute for them.

Conditions on materials and planting

Permissions in designated areas come with long condition lists, and the common ones are predictable: samples of all external materials to be approved, no external lighting without prior approval, a landscape scheme with a five year maintenance and replacement period, boundary treatments to be agreed, and removal of permitted development rights for future extensions and outbuildings.

That last one is worth noticing before you accept the decision. A condition removing Class A and Class E rights means every future garden building needs an application, which changes what the property can become.

Agree the planting palette rather than accepting a generic landscape condition. Native species of local provenance, with sizes and densities stated and a replacement obligation, is what the landscape officer wants, and settling it before determination avoids a discharge application later.
