Access chapter of a DAS for a listed building

The access chapter of a design and access statement for a listed building has to reconcile two legal duties that pull in opposite directions, and say honestly where it lands. Design and access statement listed building access is not a compliance exercise against Approved Document M. It is a reasoned appraisal that starts from the significance of the building, sets out the access need, tests the options against both, and explains the choice, including what it does not achieve.

Why a listed building application still needs an access statement

The regulations governing listed building consent applications require a design and access statement, and the access element is not optional because the building is old. Councils return applications where the access section says only that the building is listed and no changes are proposed.

Two situations produce that chapter. The first is where access improvements are the proposal: a new entrance, a ramp, a lift, an accessible lavatory. The second is where the proposal is something else entirely, a change of use or an extension, and the access implications follow from it.

The second is where most applications go wrong. Converting a listed chapel to a nursery, a barn to offices or a townhouse to flats changes who uses the building and how, so the access strategy has to be part of the application even though nobody set out to make access the subject.

The two duties pulling in opposite directions

Section 16(2) of the Planning (Listed Buildings and Conservation Areas) Act 1990 requires the decision maker to have special regard to the desirability of preserving the building and its features of special architectural or historic interest. The courts treat that as giving considerable importance and weight to any harm.

The Equality Act 2010 pushes the other way. Service providers have an anticipatory duty to make reasonable adjustments, which extends to physical features, and public authorities carry the public sector equality duty in section 149 when they make decisions.

Neither duty trumps the other, and neither is satisfied by ignoring the other. What resolves the tension in practice is the word reasonable in the Equality Act and the word desirability in the 1990 Act. Both allow for a solution proportionate to the building and to the service being provided.

Say all of this in the statement, briefly and in your own words. An officer who can see that you understand both duties will engage with your reasoning. One who reads a chapter that mentions only Part M will assume you have not thought about significance at all.

Reversibility as the deciding argument

Where an access intervention is contested, reversibility is usually what decides it. A conservation officer weighing harm asks whether the change can be undone without loss, and an intervention that can is a smaller harm than one that cannot.

That has practical design consequences.

• Bolt-down or clamp fixings into mortar joints rather than cut fixings into stone or brick faces.
• Freestanding or lightly fixed ramps set against a facade rather than a cut-in threshold.
• New floor structure laid over the historic floor with a separating layer, rather than lifting or cutting it.
• A lift shaft placed in a later addition, a former service stair or a compromised corner rather than in the historic core.
• Services routed in existing chases and voids, recorded before the works.

Say explicitly, in the statement, which interventions are reversible and which are not, and what physical evidence would remain if the work were removed. That paragraph does more work than any amount of policy quotation.

Where an irreversible intervention is unavoidable, say so and justify it. Cutting a threshold to achieve level entry may be the right answer on a building with a modern replacement step, and honest reasoning about that is far more persuasive than describing it as a light touch.

Ramps, platform lifts and threshold options compared

Set out the realistic options and compare them on the same terms: how much of the access need each meets, what fabric each affects, whether it is reversible, and what it costs to maintain.

Ramp gradients follow the standard relationship between gradient and going in Approved Document M, with steeper gradients permitted only over shorter runs and level landings between flights. Run the arithmetic on the actual level difference before proposing a ramp, because a 600 mm rise at a gradient suitable for a long run needs roughly 12 metres of ramp plus landings, and most historic frontages do not have it.

Where the accessible route runs across grounds with mature trees, the construction of a new path or ramp within a root protection area is its own constraint, and the BS 5837 tree categories should be established before the route is fixed.

Illustrative example

An illustrative case: a Grade II former assembly hall of about 1870, three steps up to a stone entrance platform, proposed for community use. A fixed ramp to the principal entrance would need 11 m of run across a frontage 7 m wide. A platform lift in the same position would sit against the plinth and obscure carved detail. The scheme that gains consent regrades the side approach, which is already a later tarmac yard of no interest, to a level threshold at a secondary door, widens that door within an existing opening, and reorganises the internal layout so the accessible entrance leads into the same lobby as the main door rather than into a back corridor. Dignity is preserved by the internal planning rather than by the entrance position.

Evidencing that the alternatives were tested

An access chapter that presents one solution reads as a decision already made. The chapter that persuades shows the work.

Give each option a short paragraph: what it was, what it would have delivered, why it was not taken forward. Include the option the conservation officer would have preferred, if it was rejected, and say why. Include the option the client would have preferred, and say why that was rejected too, if it was.

Record any consultation. Approaching a local access group, a disabled people's organisation or the building's own users produces evidence nobody can dismiss, and the statutory requirement to say what consultation was undertaken on access is one hardly any application answers.

Where the outcome falls short of full independent access, say so plainly and set out the management measures that fill the gap: assistance on request, an alternative way of delivering the service, a review at a stated interval. A statement that claims full compliance on a building that plainly does not achieve it invites a challenge.

What the national guidance expects you to say

Historic England's advice on access to historic buildings, and its wider guidance on managing significance in decision-taking, follow a consistent sequence: understand the significance of the place, understand the access requirement, consider a range of options, and choose the one that meets the requirement with the least harm to significance.

Structure the chapter in that order and the assessment writes itself. Start with a short statement of significance drawn from the list entry, the historic development of the building and what survives. Then the access requirement, drawn from the proposed use and its users. Then the options. Then the choice, the harm, and the justification.

Where harm is caused, national policy requires it to be weighed against public benefits, and improved public access to a heritage asset is itself a recognised public benefit. Say that explicitly rather than leaving the officer to make the argument for you.

Making the drawings and the text agree

The most common failure in these applications is not the reasoning. It is that the access chapter describes a scheme the drawings do not show.

Check that every element the text relies on appears on a drawing with a dimension: the threshold detail in section, the ramp gradient and landing lengths, the lift pit or platform, the door clear opening widths, the accessible lavatory layout, and the external route surface and its falls.

Check that the fixing details in the text match the details on the drawings, because reversibility arguments live or die there. And check that the accessible route is drawn continuously from the site boundary or parking space to the entrance, since a level entrance reached by a gravel path across a fall is not an accessible route.

Scoping the supporting documents against the full list of report types early avoids the situation where the access strategy is settled and a structural or drainage constraint then unpicks it.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
