Design and Access Statement: what each section must do
A design and access statement explains why a scheme looks the way it does, not what it contains. Here is what Article 9 requires and how each section should answer it.
A Design and Access Statement is not a description of the scheme. It is an explanation of why the scheme looks the way it does, and the legal wording is specific about that. Article 9 of the Town and Country Planning (Development Management Procedure) (England) Order 2015 requires the statement to explain the design principles and concepts that have been applied, and how issues relating to access have been dealt with.
Most statements that get criticised fail on the word "why". They describe materials, elevations and unit mixes competently, and never explain what the site told the designer.
When one is legally required
Article 9 requires a statement for major development, with exceptions for engineering or mining operations and for a material change of use. It also requires one for development in a conservation area or a World Heritage Site where the proposal involves one or more dwellings, or a building with a floorspace of 100 m² or more. A statement is required with an application for listed building consent.
Below those thresholds, a statement is voluntary and often worth doing anyway. On a householder scheme in a sensitive setting, two pages explaining the design response does more good than ten pages of policy quotation. Check your authority's local validation list as well, because several require a statement on applications where the Order does not.
What the Order asks for, clause by clause
The statement has to explain the design principles and concepts applied to the development. For access, it has to explain the policy adopted for access, how development plan policies on access were taken into account, what consultation was carried out and what account was taken of its outcome, and how specific issues affecting access to the development have been addressed.
That second list is a checklist and it is worth treating it as one. Consultation in particular gets missed. Where you have held a public exhibition, met the parish council or taken pre-application advice on access, say so and say what changed as a result. Where you held no consultation, say that too, rather than leaving a required heading blank.
Context and site analysis
This is the section that earns the rest of the document credibility. It should cover the site's physical characteristics, the surrounding built form, the pattern of plots and streets, prevailing heights and roof forms, materials in the immediate context, boundary treatments, levels, trees, views in and out, and the constraints that bear on layout.
Be specific and be local. "The area is characterised by a mix of architectural styles" tells an officer nothing. "The terrace opposite has a 5.8 metre plot width, two-storey eaves at 5.4 metres, a shallow 30 degree pitch and stock brick with a cement render band at first floor" tells them you measured something.
Where the authority has adopted a conservation area appraisal, a character area study or a design code, use its language. The assessment of townscape character areas in an adopted document is the framework the officer will apply, and a statement that engages with it is harder to dismiss than one that invents its own categories.
Photographs help, with a numbered key plan. Annotated photographs help more.
The design evolution section
Officers want to see options tested and rejected. Three or four studies, with the reason each was discarded, demonstrate that the submitted scheme is a considered outcome rather than the first thing that fitted.
| What to show | What it answers |
|---|---|
| Initial constraints and opportunities plan | Why the developable area is where it is |
| Two or three massing options | Why this height and footprint |
| The pre-application advice received | What the authority asked for |
| What changed after that advice | Whether you listened |
| The final arrangement | How the constraints resolved |
Pre-application advice deserves a direct answer. Where you have followed it, say which drawing shows the change. Where you have not, explain the reasoning. Silence on advice you ignored is read as an attempt to slide it past, and officers remember their own letters.
On schemes where visual impact is contested, the statement should cross-refer to the visual assessment rather than reproduce it. Methodology belongs with the visual work, which is why verified view methodology appendices sit in the townscape report and the statement carries the design reasoning instead.
Scale, layout and appearance
Deal with each as a design judgement with evidence behind it.
Scale means the relationship between the proposal and what surrounds it, expressed in measurements. Ridge and eaves heights against neighbours, storey heights, plot coverage, the separation distances the authority applies for privacy, and the 45 degree or 25 degree tests in local design guidance where they apply.
Layout means how the buildings sit in the plot and how the spaces between them work: frontage and enclosure, overlooked public space, parking location, bin and cycle storage that is usable rather than nominal, and private amenity space measured against any adopted standard.
Appearance means materials, fenestration proportions, detailing and the junctions where buildings meet the ground and the sky. Name the materials and the manufacturers' ranges if you have them, because a condition requiring samples is coming either way and starting the conversation early shortens it.
Where the Nationally Described Space Standard has been adopted locally, give the internal area schedule against it rather than asserting compliance. Schedules get checked.
Access, which means more than the drive
The access section is where most statements thin out, and the Order asks for the most here. It has two halves and both are required.
Access to the site covers vehicular and pedestrian entry, visibility, parking provision against the adopted standard, cycle parking, servicing and refuse collection, and the public transport and walking connections the site enjoys. Where parking falls below standard, make the case with evidence rather than an assertion about sustainable travel.
Inclusive access covers approach gradients, level thresholds, door widths, circulation, lift provision, accessible parking bays, wayfinding and the proportion of accessible and adaptable dwellings required by policy. Approved Document M of the Building Regulations and BS 8300 set the technical standards, and the public sector equality duty under the Equality Act 2010 applies to the authority's decision. A statement that treats inclusive access as a Building Regulations matter to be resolved later is making a planning argument it cannot support.
Say plainly where the site is difficult. A steeply sloping plot cannot deliver level access everywhere, and explaining how the constraint was managed is stronger than claiming it was solved.
Using the National Design Guide as a spine
The National Design Guide sets out ten characteristics of well-designed places: context, identity, built form, movement, nature, public spaces, uses, homes and buildings, resources and lifespan. Structuring the statement around those headings has two advantages. It maps onto the language officers and design review panels use, and it forces you to cover nature, resources and lifespan, which design statements routinely omit.
Where a local design code exists under the National Model Design Code framework, the code's requirements take priority and should be answered point by point. Codes are written to be checked, so answer them in the order they appear.
What loses marks
Four patterns show up repeatedly in officer reports.
Repeating the Planning Statement. Policy compliance belongs there. Design reasoning belongs here. Where both documents assess the same policy, the reader stops trusting either.
Writing it after the drawings are finished. A statement produced to accompany a fixed scheme reads as retrospective justification, because that is what it is.
Describing instead of justifying. Every design claim should answer a question the context asked.
Omitting the honest difficulty. Every site has one constraint that the scheme handles imperfectly. Naming it, and explaining the trade-off, is how experienced authors signal that the rest of the document is reliable.
This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
When is a design and access statement legally required?
Article 9 of the Development Management Procedure Order 2015 requires one for major development, excluding engineering or mining operations and material changes of use, and for development in a conservation area or World Heritage Site involving one or more dwellings or 100 m² or more of floorspace. One is also required with a listed building consent application.
How long should a design and access statement be?
Long enough to explain the design reasoning with evidence. Two or three pages can be enough for a householder scheme in a sensitive setting. A major residential application usually needs twenty to forty pages because the context analysis, option testing and access sections each need drawings alongside the text.
What does the access section have to cover?
Both halves of access. Access to the site means vehicular and pedestrian entry, visibility, parking against the adopted standard, cycle parking, servicing and public transport connections. Inclusive access means gradients, level thresholds, circulation, lifts, accessible parking and the accessible dwelling proportions required by policy, with Approved Document M and BS 8300 as the technical standards.
Should the statement repeat the planning policy assessment?
No. Policy compliance belongs in the Planning Statement and design reasoning belongs in the design and access statement. Where both documents assess the same policies, officers tend to stop trusting either of them. Cross-refer between the two instead, and keep visual assessment methodology in the townscape or visual report.
Does the National Design Guide have to be followed?
It is national guidance rather than a mandatory format, but its ten characteristics map onto the language officers and design review panels use, so structuring the statement around them helps. Where a local design code has been adopted, answer the code's requirements point by point and in the order they appear.
