Design and Access Statement for listed building consent

Every application for listed building consent has to be accompanied by a design and access statement, whatever the scale of the works. That is unlike an ordinary planning application, where the requirement bites only on major development and in designated areas. Replacing six sash windows in a Grade II terraced house needs one just as much as a wholesale conversion does, and the officer reads it before the drawings.

The structure that works is not the structure most practices use. It runs significance first, impact second, justification third.

When a statement is required by the rules

The requirement attaches to listed building consent applications through the secondary legislation governing them rather than through the general planning application rules, and it applies without a threshold.

For planning permission the position is different. A statement is required for major development, and for development in a conservation area or World Heritage Site comprising one or more dwellings or 100m² or more of floor space. Plenty of works to listed buildings need both consents, in which case one statement can serve both provided it addresses each.

There is no prescribed length. A window replacement can be dealt with properly in four pages. A conversion of a Grade II* farm group will run to forty with a separate gazetteer. What matters is that the document answers the statutory questions rather than reaching a page count.

Do not simply rename a Heritage Statement and submit it. The two documents overlap but the design and access statement has to explain the design principles, the design concepts and how access issues have been dealt with, which a significance assessment on its own does not.

Describing the special interest of the building

Start with what the building is, not with what you want to do to it. The list description is where you begin and not where you stop: it was written for identification, it is not a boundary around what matters, and unlisted features inside the building are protected just as the facade is.

Build the account from evidence. Map regression, deeds, estate records, census returns, the Historic Environment Record, and the fabric itself read on site. Identify the phases of the building, say which are original and which are later, and be specific about what survives in each.

Then assess significance rather than describing it. The established framework separates evidential value, historical value, aesthetic value and communal value, and using those headings makes it obvious which parts of the building matter for which reason. A plain rear wing may hold high evidential value in its surviving structural carpentry and low aesthetic value, and the judgement matters when you propose to alter it.

A room-by-room or element-by-element table earns its place here. Rate each element as high, medium, low or intrusive, and say why. Everything later in the statement refers back to it.

Justifying the works against significance

This is the section officers turn to first and the one most commonly missing.

Take each element of the proposal and set out what it affects, what the effect is, and why it is acceptable. The statutory duty on the decision-maker is to have special regard to the desirability of preserving the building, its setting and any features of special architectural or historic interest it possesses, so your assessment has to use that language rather than the language of design preference.

National policy then grades harm. Where the proposal causes no harm, say so and show the reasoning. Where it causes less than substantial harm, that harm must be weighed against the public benefits of the proposal. Where it causes substantial harm or total loss, the tests are far stricter and the justification has to be correspondingly stronger.

Public benefits have to be real and public. Securing the optimum viable use of a building at risk is one. Increasing the floor area of a private dwelling is not.

Design evolution and options considered

Show the options you rejected. A statement that presents a single solution as inevitable reads as though no alternatives were tested, and officers assume the least conservation-friendly option was chosen for cost.

Set out two or three genuine alternatives with a sentence on why each was discounted. Where an option was rejected because it caused more harm, say so, because that is the strongest possible evidence that harm has been minimised.

Record what changed after pre-application advice or after the conservation officer's site visit, with dates. A design evolution narrative showing four iterations, each responding to a specific comment, is very hard to argue against.

Keep the drawings and the statement consistent. Where the text says the partition is 1970s plasterboard, the drawings should identify it as such, and a survey drawing marked with the phases of construction is worth several paragraphs.

Access and how it is reconciled with fabric

Access is the part people skip, and the Order asks about it directly.

Deal with approach and arrival, entrance thresholds, horizontal and vertical circulation, sanitary provision, and wayfinding. Then deal with the conflict, because in a listed building there usually is one: a level threshold may mean cutting a historic stone, a lift may mean losing part of a stair compartment, and a handrail may mean fixings into historic joinery.

The approach that works is a stated hierarchy. Achieve access without touching historic fabric where you can. Where you cannot, use a reversible intervention fixed into later material or into mortar joints rather than stone. Where even that is impossible, explain the alternative provision and the management arrangement that supports it.

Say plainly where full compliance with modern access standards is not achievable, and explain what has been done instead. An honest statement of limits is treated far more sympathetically than a claim of compliance that the drawings contradict.

Materials and reversibility

Specify, do not describe. A statement saying repairs will be carried out in matching materials tells the officer nothing and invites a condition requiring samples.

Give the mortar mix and the sand source for repointing. Give the slate type and the fixing method. Give the timber species, the section sizes, the glazing bar profile and the glass type for windows. Give the paint system. Where a modern material is proposed, say where it is proposed and why the traditional alternative was not.

Reversibility is the conservation argument that most often carries a marginal case. An intervention that can be removed in fifty years without damage is a different proposition from one that cuts into primary fabric, so identify reversibility element by element rather than claiming it in general.

Where fabric will be lost or concealed, propose recording before the works. A Historic Building Recording at the appropriate Historic England level, secured by condition, preserves the information and often secures a consent that would otherwise be refused.

An illustrative example

A Grade II early nineteenth century house, application to remove a 1980s conservatory, form an opening between two rooms in a later rear wing, and repair windows. The statement ran to eighteen pages: three on history and phasing with a phased plan, four on element-by-element significance with a table, six on the works with an impact and justification entry for each, two on access covering a reversible ramp to the rear door, two on materials with a full specification, and one on the recording proposed before the conservatory came off. Consent granted with three conditions. This example is illustrative rather than drawn from a specific case.

What officers look for first

Conservation officers read in a predictable order, so write for it.

1. Is the significance of the building assessed, or merely described, and does the assessment go beyond the list description?
2. Is every element of the proposal addressed with its effect on significance identified?
3. Is the level of harm stated in the terms national policy uses?
4. Where there is harm, is there a clear and convincing justification and, where required, a public benefit?
5. Have alternatives been considered and discounted for stated reasons?
6. Are the materials specified rather than described?
7. Do the drawings match the text?

Get those seven right and the statement does its job. A Design and Access Statement that answers them is also the document your appeal statement is built from if consent is refused, so it repays the effort twice.

One honest caveat. Conservation officers vary in how they weigh reversibility against intervention, and a scheme accepted in one authority may be resisted in another on the same fabric. Pre-application engagement is the only reliable way to find out which view you are dealing with.
