Editing a drafted heritage statement to match the asset

A drafted heritage statement will describe a type of building well and your building poorly. That is the single most useful thing to know before you edit one. Heritage statement editing significance is mostly a matter of replacing generic description with what is actually there, because the conservation officer's first question is whether the author has looked at the asset.

The statutory duties make that unavoidable. Sections 16 and 66 of the Planning (Listed Buildings and Conservation Areas) Act 1990 require special regard to be had to the desirability of preserving a listed building, its setting and any features of special architectural or historic interest it possesses, and section 72 requires special attention to the character or appearance of a conservation area. A document that does not identify those features cannot engage the duty.

Why a heritage statement has to be asset specific

National policy requires an applicant to describe the significance of any heritage assets affected, including any contribution made by their setting, in a level of detail proportionate to the asset's importance and no more than is sufficient to understand the potential effect of the proposal.

Three words in that formulation drive the edit. Describe, which means the building in front of you. Significance, which means what matters about it and why rather than a list of dates. And proportionate, which means a Grade I church and a Grade II terraced house get different treatments and a drafted statement usually pitches both at the same middle register.

What a generic draft typically gets wrong is not the policy. It is the identity of the asset: the grade, the list entry, the date of listing, the later alterations, the relationship to neighbours and the specific features the entry singles out.

Getting significance from the record and the fabric

Work from three sources and say which you used.

1. The list entry on the National Heritage List for England, which gives the grade, the date of listing and a description that often names the features considered important. Read it in full, including the parts that seem incidental.
2. The Historic Environment Record held by the county or unitary authority, which holds archaeological records, previous interventions and sometimes earlier building recording.
3. The building itself, walked through with the drawings in hand, recording what survives, what has been replaced and where the phases of alteration are legible.

Add the conservation area appraisal where one exists, historic maps to establish the plot's development, and any earlier applications on the same asset, whose officer reports will tell you what the authority has previously said matters.

Then write significance by interest and by element. Architectural, historic, archaeological and artistic interest are the usual headings, and within each you should identify which parts of the asset carry that interest at what level, including the parts that are neutral or that detract. A statement that grades every element as highly significant is as unhelpful as one that grades none.

Describing the asset as it is, not as its type

This is the paragraph most often lifted from a template and it is the one an officer reads first.

Replace phrases such as "a typical Victorian terraced property" with what the building actually presents. The bay that was rebuilt in the 1970s. The replacement windows in the rear elevation and the surviving sashes at the front. The original staircase with its handrail intact and a missing newel. The cornice in the front room and the plain ceiling in the back. The rear extension of about 1990 that has already removed the original scullery.

Two habits help. Take photographs in a numbered sequence keyed to a plan and refer to them by number in the text. And be explicit about what you could not see, whether that is a floor void, a roof space or a concealed structure, because an honest gap is better than a confident guess and the officer will find the guess.

Where the drawings and the description disagree, the description usually loses credibility. Check that every feature you describe appears on the survey drawings and that every alteration shown on the drawings appears in your description. The same discipline applies across all drafted documents, as set out in our note on factual errors to look for in a drafted planning document.

Assessing the effect of this proposal

Effect is assessed element by element, and this is where a drafted document usually collapses into a conclusion.

Take each part of the proposal in turn and say what it does to the significance you have just identified. Removal of a chimney breast: which floor, what survives, whether the stack is retained, what is lost. A new opening in a spine wall: the age of the wall, whether the opening is reversible, how the head is formed. Replacement windows: the survival of the existing, the profile proposed, the glazing bar arrangement, the reveal depth.

Then reach a conclusion in the language of the policy test, and reason it. Where harm arises, say whether you contend it is substantial or less than substantial, state where within that range you place it, and identify the public benefits you rely on. A conclusion of "no harm" on a proposal that removes historic fabric will be rejected, and it damages the credibility of the rest of the document.

Setting deserves its own short section where the proposal is near rather than to a listed building. Describe how the asset is experienced, identify the views that contribute to its significance, and assess the effect on those views rather than on the asset's fabric.

Proportionality to the grade and the works

Match the depth of the document to what is at stake. A like-for-like repair to a Grade II building needs a short, precise statement. A change of use with internal reordering in a Grade II* building needs a full account of the plan form, because plan form is often where the significance of a higher-graded interior sits.

A useful test is whether every page of your statement is doing work for the decision. Historic background that does not bear on the proposal, general observations about the period, and long policy recitation can all be cut. What cannot be cut is the description of the affected fabric, the assessment of effect, and the justification.

Shopfronts are a recurring case with their own conventions, and our note on a heritage statement for a listed shopfront goes through the elements an officer expects to see addressed.

What the conservation officer checks first

In roughly this order.

Whether the grade, list entry and address are correct, because an error there suggests nothing else has been verified. Whether significance is specific to the asset or generic to its type. Whether later alterations are acknowledged rather than airbrushed. Whether the effect of each element of the proposal is assessed rather than summarised. Whether the harm conclusion is reasoned and consistent with the description. And whether the drawings show what the text describes.

Anything left as a placeholder is read as a gap in the work. A draft that carries "[TO BE CONFIRMED]" against the list entry number or the date of listing is telling you precisely which check to do before submission, which is a safeguard rather than a defect, but it has to be closed out.

Where specialist input becomes necessary

There is a line beyond which a well-edited statement is not enough, and it is worth recognising early.

Loss of historic fabric on a higher-graded asset, structural intervention, a scheme touching below-ground archaeology, or a proposal involving substantial demolition all call for specialist authorship. Where a building is to be altered or lost, a council may require Historic Building Recording to the appropriate Historic England level, and councils usually expect a suitably qualified author for that and for archaeological work, with professional review strongly advised. You can see the route for review and sign-off through the professional directory.

One honest uncertainty. The boundary between substantial and less than substantial harm is a judgement that has been litigated repeatedly, and practitioners disagree about where a given intervention falls. State your position and your reasoning rather than asserting a category, because the reasoning is what an inspector will engage with.

PlanScope drafts the Heritage Statement structured to UK planning policy, citing its sources and flagging the facts it cannot verify, which turns the work into an editing task rather than a writing task.
