Registered parks and gardens and the setting test

A registered park and garden setting assessment is the whole game, because registration itself controls nothing. There is no consent equivalent to listed building consent for a registered landscape, and no statutory duty on the decision-maker of the kind that applies to listed buildings and conservation areas. What registration does is identify the landscape as a designated heritage asset, which brings national heritage policy into play and triggers consultation with heritage bodies.

So a scheme near a registered park succeeds or fails on whether it harms the significance of the landscape through changes to its setting, and on whether any harm is outweighed.

What registration means and what it does not control

The Register of Parks and Gardens of Special Historic Interest in England is compiled by Historic England under the historic buildings legislation. It records designed landscapes of historic interest: country house parks, public parks, cemeteries, hospital and institutional grounds, town gardens and a handful of twentieth century landscapes.

Registration does not require consent for works inside the registered area. An owner can fell a tree, alter a path or build a shed without any registration-specific permission, subject to the ordinary controls that apply anyway, such as planning permission, tree preservation orders, listed building consent for structures within the park, and scheduled monument consent where relevant.

What registration does is two things. It makes the landscape a designated heritage asset for policy purposes, so the conservation of its significance carries great weight in decisions. And it triggers statutory consultation: the national heritage body must be consulted on development affecting the higher grades, and the national body for historic designed landscapes must be consulted on development affecting registered parks and gardens of any grade.

That consultation is why applications near registered landscapes attract detailed responses from organisations the applicant has never heard of, often several weeks into determination.

Grades and how they affect weight

Registered landscapes are graded I, II* and II, on the same scale as listed buildings. Grade I and II* are the higher grades and attract consultation with the national heritage body as well.

Grade affects weight rather than the test. A Grade II registered park is still a designated heritage asset, and harm to its significance still carries great weight. What changes is the strength of the case needed to justify harm, and the likelihood that the national body will engage in detail.

One practical consequence: a scheme that would pass with a short heritage note near a Grade II urban cemetery may need viewpoint analysis and photomontage near a Grade I landscape park, because the consultee's expectations differ.

Setting and how it is defined for a designed landscape

Setting is the surroundings in which a heritage asset is experienced. Its extent is not fixed, it is not a buffer zone, and it is not the same as the registered boundary.

For a designed landscape that definition is unusually demanding, because the landscape was laid out to be experienced from and towards particular points. Setting for a park may include:

• Views out from the house, terraces and principal walks, framed deliberately by planting.
• Views in from roads, approaches and public rights of way, including the arrival sequence along a drive.
• Eyecatchers, temples, lodges and obelisks placed in or beyond the park to terminate a vista.
• Borrowed landscape: hills, church towers and woodland belts outside the boundary that were incorporated into the composition.
• The agricultural or parkland character of the land around the park, which provides its context.
• Quieter contributors such as tranquillity, darkness at night and the absence of modern intrusion.

A development half a mile outside a park boundary can affect setting materially if it sits in a designed vista. A development immediately adjoining can have no effect at all if it is screened by a belt planted for that purpose. Distance tells you very little on its own.

Assessment method and viewpoint selection

Use the published five step approach for assessing setting rather than inventing a method.

1. Identify which heritage assets and their settings are affected, including listed buildings and scheduled monuments inside the park.
2. Assess whether, how and to what degree those settings contribute to the significance of the asset.
3. Assess the effect of the proposed development on that significance.
4. Explore ways to avoid or reduce harm, and to enhance where possible.
5. Record the judgement and its reasons.

Step two carries the weight and is the one most often skipped. The question is not whether the site is visible from the park. It is whether the part of the setting affected contributes to why the landscape is designated, and how much.

Viewpoint selection should be agreed rather than chosen unilaterally. Ask the council's conservation officer and the designed landscapes consultee for their preferred viewpoints at pre-application stage, and include the ones they name even where they are unhelpful to you. A viewpoint set that omits the obvious view invites a consultee to produce their own photographs, which is a worse outcome.

Seasonality matters more here than almost anywhere else. A park screened by a mature deciduous belt in July is open in January, so photography should be taken with the trees bare, or both conditions should be shown. Historic mapping is worth including too, because it shows which planting was part of the design and which arrived later and might be removed by a future owner.

Where the scheme is large or the view is contested, a Townscape and Visual Impact Assessment or, in a rural setting, a Landscape and Visual Impact Assessment provides the visual evidence. Neither replaces the heritage judgement, which is a separate exercise using heritage method. Submitting a landscape assessment and calling it a setting assessment is a frequent and easily spotted shortcut.

Harm and public benefit in the balance

National heritage policy distinguishes substantial harm, which requires an exceptional justification, from less than substantial harm, which is weighed against the public benefits of the proposal. Most cases involving registered landscapes fall into the second category.

Two points are worth being disciplined about.

Less than substantial does not mean minor. The category covers a wide range, and the weight given to harm rises across it. Say where in that range you think the harm falls and why, rather than using the label as though it settles the matter.

Public benefits have to be public. Housing delivery, public access, heritage enhancement, economic activity and biodiversity gain can all qualify. The applicant's profit does not. A benefits list padded with private advantages weakens the credible items on it.

Where harm can be reduced by design, do it before submission rather than offering it at committee. Moving a building 40 metres, dropping a ridge, relocating lighting away from a vista, or planting to restore a lost belt are all more persuasive as part of the scheme than as concessions.

What the heritage statement should contain

Proportionate is the operative word, but proportionate to the asset rather than to the application. A small scheme near a Grade I landscape needs a proper assessment.

A Heritage Statement covering a registered park should include:

1. Identification of every designated asset affected, with grade and list entry reference.
2. A summary of the significance of the registered landscape, drawn from the register entry, the historic environment record and any conservation management plan, with historic mapping.
3. An account of the designed intent: who laid it out, when, and what the composition was meant to do.
4. Analysis of setting, identifying which elements of setting contribute to significance.
5. Assessment of effect, with viewpoints, photography in leaf-off conditions and photomontage where the effect is contested.
6. Mitigation and enhancement incorporated into the scheme.
7. A reasoned conclusion on the level of harm and its place in the balance.

Councils usually expect a suitably qualified author for this work, and professional review is strongly advised before submission. Where archaeology is also engaged, which is common in parkland with earlier earthworks, that is a separate assessment again.

The comparison with other area designations is instructive: what a conservation area designation controls is a control regime, whereas registration is a policy designation with no consent attached.
