Appeals against refusal of consent for relevant demolition

Demolishing a building in a conservation area needs planning permission for relevant demolition, and a refusal is appealed under section 78 of the Town and Country Planning Act 1990 like any other refusal. Conservation area consent was abolished in October 2013 and folded into the ordinary planning permission regime, so there is no separate consent to appeal and no separate appeal form. What is different is the criminal exposure: carrying out relevant demolition without permission is an offence under section 196D of the 1990 Act, and that changes how a developer should behave while an appeal is pending.

Most refusals of relevant demolition turn on one of two things. Either the building makes a positive contribution to the character or appearance of the conservation area and its loss is unacceptable, or the replacement scheme is not good enough to justify the loss. The second is far more common, and it is the easier of the two to fix.

Why demolition in a conservation area needs permission

Section 72 of the Planning (Listed Buildings and Conservation Areas) Act 1990 requires the decision maker to pay special attention to preserving or enhancing the character or appearance of a conservation area. Demolition of an unlisted building that contributes to that character is the sharpest form of change the area can experience, which is why it was brought inside the permission regime rather than left to the prior notification route.

Outside conservation areas, demolition of most buildings falls under Part 11 of Schedule 2 to the General Permitted Development Order 2015, with a prior approval for the method of demolition and site restoration. That route is not available for relevant demolition in a conservation area.

What counts as relevant demolition

Relevant demolition means demolition of a building in a conservation area, with exceptions. A Direction made by the Secretary of State describes classes of building whose demolition is not development at all, covering small buildings below stated volume thresholds and certain gates, walls, fences and means of enclosure below stated heights. That Direction has been reissued more than once, so check the version in force rather than working from an old note.

Two traps come up repeatedly.

• Partial demolition. Taking down a rear wing, a chimney stack or a boundary wall can be relevant demolition in its own right, and a scheme described as alterations may need the demolition element expressly applied for.
• Facade retention. Removing everything behind a retained front wall is demolition of the building for these purposes in most officers' view, and an application that calls it refurbishment invites a validation query at best.

The criminal offence of unauthorised demolition

Section 196D makes it an offence to carry out or cause relevant demolition without the required planning permission. Conviction can lead to an unlimited fine, and the offence attaches to the person who did the work as well as the person who caused it to be done.

There is a statutory defence where the demolition was urgently necessary in the interests of safety or health, the works were limited to the minimum immediately necessary, and written notice justifying the works was given to the local planning authority as soon as reasonably practicable. That defence is narrow. A structural engineer's letter obtained the week before, with no notice to the council and a site cleared to ground level, has failed it often enough that it should not be relied on as a strategy.

The practical consequence is simple. While an appeal is pending, nothing comes down. A developer who demolishes during an appeal destroys the appeal's subject matter and acquires a prosecution risk at the same time.

Grounds of appeal against refusal

The appeal is a full planning appeal, so the grounds are the ordinary ones: the decision misapplied policy, misjudged the contribution the building makes, gave inadequate weight to the benefits of the replacement, or failed to consider the condition of the building.

Lead with the contribution question, because it sets the test for everything else. Where the building is a neutral or negative element in the conservation area, the section 72 duty is satisfied by a replacement that preserves or enhances, and the heritage balance never engages. Where it makes a positive contribution, the loss is harm to the designated asset and has to be weighed against public benefits.

Evidence that moves this argument:

• An assessment of the conservation area's character that identifies which elements carry the significance, not a general description of the street
• A dated survey of the building's construction history, with the alterations that have eroded its interest
• Condition evidence where repair is said to be uneconomic, with costings prepared by a surveyor rather than asserted
• Photographs from the public viewpoints the officer relied on

A Heritage Statement that follows Historic England's guidance on assessing significance is the right vehicle for the first three. Where the refusal turned on the statutory balance rather than on the facts, the note on heritage harm refusals and the statutory balance sets out how inspectors have structured that exercise.

Replacement scheme evidence

An appeal against refusal of demolition alone, with no replacement, almost always fails. The Framework's historic environment policies expect the decision maker to look at what will stand in the building's place, and a cleared site in a conservation area is harm with no counterbalancing benefit.

So appeal the demolition and the replacement together wherever the application allowed it. Where the original application was demolition only, consider a fresh application for the full scheme rather than an appeal that cannot answer the obvious question.

Illustrative example. A 1960s infill shop unit in a Victorian high street conservation area, refused demolition and replacement with three flats over a retail unit. The officer accepted the existing building was a negative element but refused on the design of the replacement. On appeal the stronger case was not about the demolition at all: it was a revised elevation with a parapet height matching the neighbours and shopfront proportions taken from the surviving Victorian examples. The demolition argument followed the design argument rather than leading it.

Conditions requiring a contract before demolition

Where permission is granted for demolition of a building that contributes to a conservation area, authorities commonly impose a condition preventing demolition until a contract for the redevelopment works has been made and permission implemented. The purpose is to avoid a gap site, and the practice has long-standing support in national guidance on the historic environment.

Expect such a condition and plan for it. It affects funding sequence, because the building cannot come down until the construction contract is signed, and it affects programme where the site needs early enabling works. Where the condition as drafted is unworkable, negotiate the wording before decision rather than applying to vary it later under section 73.

Recording the building before works

Where demolition is permitted, a condition requiring recording of the building before it is lost is standard. The level of recording follows Historic England's recording levels 1 to 4, and the condition usually requires a written scheme of investigation approved in advance, with the archive deposited with the local Historic Environment Record.

Commission the historic building recording while the building is still accessible and before any strip-out. Recording a building after the plaster has come off and the staircase has gone produces a poor archive and an unhappy conservation officer. And where the recording condition is pre-commencement, demolition cannot lawfully start until the written scheme is approved, which is a programme item rather than a formality.

Appeal decisions on comparable buildings are useful here, within limits. They are indicative of how inspectors approach contribution and replacement quality rather than binding precedent, and the guide to using appeal decisions in a planning application explains how to deploy them without overstating their weight.
