Registered parks and gardens: what registration means for planning

England has a national Register of Parks and Gardens of Special Historic Interest covering more than 1,700 designed landscapes. The entries range from country-house parks and formal gardens to public parks, cemeteries, town squares, institutional landscapes and other deliberately designed open spaces.

A registered park or garden is a designated heritage asset, so its significance must be taken seriously when planning permission is sought for development affecting the registered landscape or its setting. Registration does not, however, create a separate registered-park consent in the way that listing creates Listed Building Consent.

That distinction is important. Development is controlled principally through the ordinary planning system, but the heritage status materially changes the assessment, consultation requirements and weight given to conservation.

What is a registered park or garden?

The national register identifies designed landscapes of special historic interest. Historic England administers the Register, which was established through the National Heritage Act 1983; the statutory register provision now sits in section 8C of the Historic Buildings and Ancient Monuments Act 1953 as amended.

The word garden is much broader than a domestic garden. Registration can cover landscaped estates, urban parks, cemeteries, public squares, institutional grounds and other intentionally designed landscapes. The interest is in the historic design and development of the landscape: its layout, structures, planting framework, views, circulation, water features and relationships between its component parts.

The official record is on the National Heritage List for England. Always read the individual list entry when assessing a site: the name alone tells you little about which parts of the landscape and which historic relationships make it significant.

The three grades

Registered parks and gardens use the same three grades familiar from listed buildings:

• Grade I – landscapes of exceptional interest;
• Grade II* – particularly important landscapes of more than special interest; and
• Grade II – landscapes of special interest.

All three grades are designated heritage assets. The grade becomes especially important where substantial harm or total loss is alleged. Under the current August 2026 NPPF framework, substantial harm to or loss of a Grade II registered park or garden should be exceptional, while Grade I and II* registered parks and gardens are treated among the assets of the highest significance for which substantial harm or loss should be wholly exceptional.

That does not mean minor change to Grade I or II* land is automatically refused. The first job is still to identify the actual significance of the landscape and the degree to which the proposal would affect it.

There is no separate registered park or garden consent

Registration itself does not create a special consent application. If the proposed works need planning permission, their effect on the registered landscape is assessed as part of that planning application. If the works are not development or are genuinely permitted development, registration alone does not create a separate application simply because the land is registered.

Other controls can overlap. A registered landscape may contain:

• listed buildings and listed garden structures;
• scheduled monuments;
• conservation areas;
• Tree Preservation Orders;
• archaeological remains; and
• ecological or landscape designations.

Those controls must be checked separately. Registration does not replace them.

How is a planning application assessed?

The starting point is the general designated-heritage-asset framework explained in our guide to heritage significance and harm. The authority needs to understand what is significant about the registered landscape, how the proposal affects that significance and what weight should be given to any harm.

Relevant matters can include:

• historic layout and designed routes;
• formal or informal landscape structure;
• views, vistas and visual sequences;
• relationship between a principal building and its grounds;
• historic boundaries, entrances and approaches;
• parkland trees, avenues, woodland blocks and planting structure;
• water features, terraces, garden buildings and monuments;
• archaeological evidence of earlier landscape phases; and
• the contribution made by the wider setting.

A proposal can therefore affect significance without physically removing a historic garden feature. New development outside the registered boundary may harm an important approach, designed view or the relationship between the landscape and surrounding countryside.

Setting does not stop at the registered boundary

The registered boundary identifies the designated asset; it does not define the maximum extent of its setting. As with other heritage assets, setting is the surroundings in which the asset is experienced and its extent is not fixed.

For some parks the setting may be relatively contained. Others were deliberately designed around long views, borrowed landscape, approaches through adjoining land or a strong visual relationship with an estate village, church, ridge or wider countryside. Evidence is what matters, not an arbitrary buffer.

Equally, being visible from a registered park does not automatically mean development causes heritage harm. The assessment must explain how that part of the surroundings contributes to significance and what the proposed change would actually do to that contribution.

Historic England and the Gardens Trust consultation

Registered landscapes have specific consultation arrangements. Historic England states that local planning authorities must consult it on planning applications affecting Grade I or Grade II* registered parks and gardens. The Gardens Trust is consulted on applications affecting registered parks and gardens regardless of grade. The Government has now confirmed statutory consultee reforms that will replace this statutory role with a notification requirement for development within registered parks and gardens, but the change is not yet operative and the current consultation duty remains until the implementing regulations commence.

That does not transfer the planning decision to either consultee. The local planning authority remains the decision-maker, but their specialist heritage advice can be highly material, particularly where the application affects the integrity, significance or setting of the registered landscape.

What should a heritage statement cover?

A planning application affecting a registered park or garden should include a proportionate heritage assessment. Depending on the proposal it may need to cover:

• the Historic England register entry and designation history;
• historic maps, plans, photographs and documentary evidence;
• the evolution of the designed landscape;
• surviving historic features and landscape structure;
• key views, approaches and spatial relationships;
• the contribution of setting;
• any overlapping listed buildings, archaeology or other heritage assets;
• the proposal’s effects during construction and operation; and
• opportunities to avoid harm, restore lost features or better reveal significance.

For major development or particularly significant landscapes, a specialist historic-landscape assessment may be necessary rather than a generic architectural heritage statement.

Can development ever improve a registered landscape?

Yes. Registration is not intended to fossilise a landscape. Well-considered development can repair fragmented layouts, restore historic routes or planting, remove intrusive later features, improve management, reveal important views or secure a viable long-term use for associated buildings and land.

The current NPPF heritage framework expressly supports proposals that sustain and enhance significance. Where a scheme produces genuine heritage benefits, those should be identified and evidenced rather than treating heritage solely as a constraint.

A useful example is City & Country Bramshill Ltd v Secretary of State for Housing, Communities and Local Government [2021] EWCA Civ 320, which concerned a Grade I registered park and garden alongside Grade I listed Bramshill House. The Court of Appeal confirmed that there is no single mandatory method for balancing heritage harm and heritage benefits: the decision-maker must identify significance, assess harm and benefits lawfully, and give them the weight required by the statutory and policy framework.

Permitted development

Unlike a listed building, a registered park or garden is not by itself a category of Article 2(3) land. Registration alone therefore does not automatically switch off the GPDO rights that use that definition.

But the position on any particular site can be more complicated because the land may also be within a National Park, National Landscape, conservation area, World Heritage Site or another category with its own GPDO restrictions. Separate listed-building or scheduled-monument controls may also make apparently permitted works unlawful without the relevant heritage consent.

Always check the exact permitted development class and every overlapping designation rather than assuming registration either removes all rights or leaves the site unconstrained.

A future statutory duty has been enacted but is not yet in force

Section 102 of the Levelling-up and Regeneration Act 2023 would insert a new section 58B into the Town and Country Planning Act 1990. When commenced, it would require special regard to the desirability of preserving or enhancing registered parks and gardens and their settings when specified planning permissions are considered.

As at 20 August 2026, section 102 has not been commenced. The current planning assessment should therefore not be described as though the new section 58B statutory duty already applies. Registered parks and gardens are nevertheless designated heritage assets under the NPPF and their conservation already carries substantial planning-policy weight.
