Heritage & Design Access Statements in London

A heritage statement sets out what is significant about a building or its setting, assesses the impact of the proposed works on that significance, and explains the design response that minimises harm or delivers benefit. For listed buildings and sensitive conservation-area sites, it is a central part of the application, and the weight a case officer gives a proposal often depends on how clearly significance and impact are articulated.

We make sure the heritage case and the architectural proposal are developed together rather than written to justify a fixed design after the fact. We prepare heritage statements in-house, and for the most complex or highly graded heritage assets we can involve specialist heritage consultants where that adds value. We are transparent about which applies to your project.

A heritage statement is only as good as its understanding of why a building matters. We assess significance through the building fabric itself and, where warranted, historic maps, archive records and the development of the area — distinguishing the elements of real architectural or historic interest from later, lower-value alterations. That assessment is what allows a proposal to be directed towards the least sensitive parts of the building, and it is the foundation a conservation officer expects every heritage case to rest on.

For a designated asset, national policy frames the decision in specific terms: any harm is categorised as substantial or less-than-substantial and must be weighed against the public benefits of the proposal, with great weight given to the asset’s conservation and a requirement for clear and convincing justification. A heritage statement that ignores this language leaves the officer to make the case for you. We write to these tests directly, setting out the level of harm honestly and the justification or benefit that answers it.

A good heritage statement is scaled to the asset and the works. A modest alteration to a Grade II house needs a focused, evidenced document, not a generic essay that buries the relevant points; a complex change to a highly graded building needs more. Over-long, templated statements actively weaken an application by obscuring the argument. We pitch the depth to what the proposal genuinely requires, so the case is clear and the officer can find it.
