What a design and access statement costs to produce

Design and access statement cost is mostly a question of hours, and the hours are set by three things: whether the site carries a heritage constraint, how much of the design rationale already exists in a form you can use, and how many rounds of client change the document has to absorb before submission.

For a practice, the number that matters is not what a consultant would charge. It is how much of the fee proposal was allocated to the planning submission and how much of that allocation the statement consumes.

When a statement is required

Article 9 of the Development Management Procedure Order 2015 sets the requirement. A statement is needed for major development, and for development in a conservation area or World Heritage Site where it comprises one or more dwellings or 100 square metres or more of floorspace.

Listed building consent applications require one regardless of scale, and that is the case most practices meet most often on small jobs.

Householder development outside a designated area does not need one. Councils sometimes ask anyway, and a short design note is often worth writing on its merits, but it is not a validation requirement and should not be priced as if it were. Check the local validation list before you agree to produce one.

What the content requirement actually demands

The statement has to explain the design principles and concepts applied to the development, covering amount, layout, scale, landscaping and appearance, and it has to explain how issues relating to access have been dealt with.

For listed building consent it goes further: the statement must explain how the design takes account of the special architectural or historic interest of the building and the physical features that justify its designation.

That is a short list of requirements and a wide range of possible responses, which is where the cost variation comes from. A statement that answers the requirement in eight pages of specific reasoning is a better document, and usually a faster one to produce, than a thirty page volume of context photographs and policy extracts. The structure and expected sections are set out on our Design and Access Statement page.

Why the design section takes the time

Writing the design section is not transcription. It is the point at which the practice has to articulate decisions that were made intuitively over several months.

The expensive part is the evidence chain: why this massing, given what is either side. Why this material, given the palette of the street. Why this window rhythm, given the host building. Each of those needs a supporting observation from the site analysis, and if the site analysis was never written up, it has to be reconstructed.

Practices that record design decisions as they are taken, with a dated note and the sketch that settled it, produce the statement in a fraction of the time. Those that leave it to the week before submission pay for the same thinking twice.

There is a second cost that nobody prices. Writing the statement exposes weak decisions. That is valuable and it is also how a two day task becomes a five day one, because the honest response to an argument you cannot make is to change the design.

Access and inclusive design

The access section is routinely the weakest part of a submitted statement and the quickest to improve.

It has to address how everyone will approach and use the development: the approach from the street and from parking, level thresholds, door widths, circulation, changes of level and how they are handled, and the provision made for people with reduced mobility, sight or hearing.

Where the local plan carries accessible housing policies or a proportion of wheelchair user dwellings, say which units meet which standard and show it on the drawings. The statement should also record any consultation with an access group or with users, because the requirement refers to consultation undertaken.

Budget for coordination rather than for writing. The words take an hour. Confirming that the drawings actually deliver what the words claim takes longer, and that check is the part that protects you at condition discharge.

Heritage work and what it adds

A listed building or a conservation area site changes the document from a design explanation into an argument about harm.

You need the significance of the asset described before you can explain how the proposal responds to it. On a listed building that means understanding the phases of the building, the features that contribute to its interest, and the elements that do not. That work belongs in a heritage statement, and the design and access statement should reference it rather than repeat it.

The practical question for a fee proposal is whether the practice is producing both documents or only one. Two documents by one author risks duplication. Two documents by two authors risks contradiction, which is worse, because a case officer reading a design rationale that conflicts with the heritage appraisal will ask which one the applicant stands behind.

Pricing a listed building submission as if it were the same exercise as a commercial refurbishment is the most common underpricing error in small practice.

Reusing practice material without templating

Every practice has a library: site analysis methods, standard access text, sustainability boilerplate, the studio's design philosophy. Reuse is legitimate and it is how the document becomes affordable.

The line is between structure and substance. Reusing a structure, a set of headings and a house style saves time and improves consistency. Reusing paragraphs about a different site produces a document that reads as generic, and officers spot it immediately because the specifics do not connect to the drawings.

A workable rule: reuse anything describing how your practice works, write fresh anything describing this site, this building and this proposal. Where a drafting tool assembles the structure and flags the missing site facts, the time saved sits in the first category rather than the second. PlanScope prices that at one free report, then £50 per report, with a Professional tier at £150 per month or £600 per year that removes branding and adds your own logo. See pricing for what each tier includes.

Any drafted statement still needs the practice's review before it goes out, because the design argument has to be one the author can defend at committee.

Where the unbilled hours go

Four places, in my experience of watching fee proposals go wrong.

1. The statement is written after the drawings are frozen, so every inconsistency becomes a drawing revision rather than a text edit.
2. Client comments arrive on the document rather than on the design, and each round costs a day.
3. The access section is coordinated late, and the coordination finds a problem.
4. The council asks for something the validation list did not require, and the practice produces it without a variation.

The fourth is worth resisting politely. Ask which validation requirement the request relates to, and if there is not one, offer a short addendum rather than a new document. Officers ask for things they would like. That is different from things you agreed to provide, and the difference is billable time.

Where a scheme has already been refused once, the cost of revisiting the statement usually exceeds the cost of a condition you did not negotiate, so build the resubmission risk into the fee.
