Locally listed buildings and what a local list changes

Locally listed building rules are not rules in the way statutory listing produces rules. A local list is a register the council compiles of buildings and structures it considers to have local heritage interest, and inclusion creates no new consent requirement, no offence and no restriction on permitted development. What it does is establish the building as a non-designated heritage asset, which changes how any planning application affecting it is decided. For a householder that distinction is the whole of the practical answer: you do not need listed building consent, and you may still be refused permission for the extension.

How a local list is compiled

Councils compile local lists using published selection criteria, often following the national heritage body's advice on local heritage listing. The criteria typically cover age and rarity, architectural or artistic interest, group value where a building contributes to a terrace or a set piece, archaeological interest, historic association with a person or event, landmark quality, and social or communal value such as a chapel, a school or a former cinema.

Adoption varies. Some authorities adopt the list as a supplementary planning document following consultation, some adopt it by committee resolution alongside a local plan policy, and some maintain it as an evidence base without formal adoption. The route affects how much weight the list carries and whether there is a formal review cycle, so ask the conservation team how yours was adopted.

Owners are not always notified. Some councils write to owners before adding a building, and some do not, so the first indication may be a comment in a pre-application response. It is worth checking the list for your property before you commission drawings, because a local list is one of the constraints that a standard search will not necessarily surface. Other designations behave the same way, and non-statutory designations that still stop schemes covers the wider set.

What status it carries in policy

National policy treats a non-designated heritage asset as a material consideration. Where an application directly or indirectly affects one, the effect on its significance must be taken into account, and in weighing the application a balanced judgement is required having regard to the scale of harm or loss and to the significance of the asset.

Read that carefully, because the wording is deliberately weaker than the tests for designated assets. There is no statutory duty of the kind that applies to listed buildings and conservation areas. There is no presumption. There is a balance, and the heavier side of it is determined by how important the building actually is and how much of that importance your scheme removes.

Local plan policy sits on top and is where the real weight comes from. Many authorities have a development management policy requiring proposals affecting a non-designated heritage asset to conserve those elements that contribute to its significance, and some go further in identifying particular features. Read the policy rather than the list entry, because the policy is what the officer applies.

What consent you actually need

Nothing additional. Local listing does not create a consent regime.

Three consequences follow, and they surprise people in both directions.

Permitted development rights are unaffected. A locally listed house outside a conservation area retains the householder rights in Schedule 2 Part 1 of the GPDO 2015 in full. A rear extension within the limits, a rooflight, replacement windows, render, a garden room: all permitted, and the council cannot refuse what it has no power to determine.

Where an application is needed, the local listing becomes a material consideration and can support a refusal. So the same extension that would be permitted development at 3 metres deep may be refused at 5 metres because of the effect on the building's significance.

And the council can remove the permitted development rights, but only by making an article 4 direction over the property or the area. Local listing itself does not do it.

The balanced judgement in practice

The judgement really is a balance, which means schemes succeed on locally listed buildings regularly. What decides it is whether the scheme affects the features that make the building interesting.

A Victorian villa may be locally listed for its front elevation, its bay windows, its chimney stacks and its relationship to the street. Extending at the rear, below the ridge, in a subordinate form with matching brick, touches none of that. Replacing the timber sashes on the front elevation with white plastic units touches all of it.

So the design strategy is to identify what carries the significance and leave it alone. Rear and side extensions set back from the principal elevation, interventions below eaves or ridge level, retention of chimneys and original openings, and reversible alterations internally all tend to be acceptable. Loss of the principal elevation's composition, removal of a landmark feature, and changes that break the group value of a terrace or a pair do not.

Be aware of the group value point in particular. Where a local list entry covers a row, the harm is assessed against the row rather than against your house, and a change that reads as a gap in a rhythm carries more weight than its size suggests.

Demolition

Demolition is where the weakness of local listing becomes obvious, and where councils respond with other tools.

Demolition of a building outside a conservation area may fall within Part 11 of Schedule 2 to the GPDO 2015, subject to prior approval of the method of demolition and the restoration of the site. Those are the only matters the authority may consider on that prior approval. The heritage significance of the building is not among them.

Councils faced with the demolition of a locally listed building therefore reach for two other mechanisms. An article 4 direction removing the demolition right, which takes time. Or a building preservation notice under section 3 of the Planning (Listed Buildings and Conservation Areas) Act 1990, which gives the building temporary protection as though it were listed for six months while the Secretary of State considers statutory listing.

A building preservation notice is a serious step for an owner. During the six months, works need listed building consent, and if the building is then listed the protection becomes permanent. If you are contemplating the demolition of a building on a local list, expect that response and take advice before serving any notification.

Evidence expected with an application

The evidence should be proportionate to the significance of the asset and to the scale of what you propose. A rear extension on a locally listed terrace does not need a hundred page report, and a case officer will not thank you for one.

1. A short statement of significance identifying what the building is valued for, drawing on the local list entry, the authority's criteria and your own observation.
2. Historic mapping and any available historic photographs, which are usually held by the county record office.
3. A photographic record of the elevations and the features affected.
4. An assessment of the effect of the proposal on each element of significance, stated element by element.
5. The design response: what has been avoided, what has been set back or reduced, what materials match.
6. Where harm remains, the justification and the public benefits offered against it.

Point four is the one that carries the decision. An officer comparing your assessment with their own will look for whether you engaged with the features named in the list entry. Silence on a named feature reads as avoidance.

An illustrative example. A locally listed 1890s end-of-terrace, listed for its brickwork, timber sash windows and the unbroken parapet across the row. The owner wanted a full-width rear extension and a loft conversion with a front dormer. The rear extension went ahead as designed. The front dormer was dropped and replaced with conservation rooflights on the rear slope, because a dormer would have broken the parapet line the entry specifically identified. The sashes were repaired rather than replaced. The application was approved at officer level with no heritage objection.

Getting a building added or removed

Nominations usually come from residents, amenity societies, parish councils and ward members, and most authorities publish a nomination form and the criteria against which it will be assessed. Nominations are commonly used to try to prevent demolition, and a nomination made after a demolition notification has been submitted will not slow that notification down.

Removal is harder and the route depends on how the list was adopted. Where it forms part of a supplementary planning document, removal happens at review. Where it was adopted by resolution, the conservation team can usually bring a reassessment to committee. The case for removal has to be evidential: that the building has been altered so that the features identified have gone, that the attribution in the entry is wrong, or that the original assessment applied the criteria incorrectly. Arguing that the listing is inconvenient will not succeed.

Two final points of comparison. Local listing is a planning matter and it operates entirely separately from private law restrictions on your title, which behave differently again, as set out in restrictive covenants compared with planning rules. And if you are buying rather than extending, a local list check belongs in the same exercise as checking a site for constraints before you make an offer, because it will affect what you can do and the search may not mention it.
