How does Vestige approach it?
- 1
Conservation area appraisal review
We start with the local authority's adopted character appraisal and management plan, identifying what specifically contributes to character on your street and frontage.
- 2
Article 4 and constraints check
We confirm whether an Article 4 direction applies and what permitted development rights have been removed, critical before any design work begins.
- 3
Design dialogue with the team
We work with architects to refine materials, proportions and detailing so the proposal preserves or enhances character, the statutory test under section 72.
- 4
Heritage and planning statement
We prepare the supporting documents that engage directly with the conservation area appraisal and demonstrate compliance with local heritage policy.
- 5
Submission and negotiation
We submit the application, respond to officer comments, and negotiate amendments where needed to reach consent.

Conservation Areas vs Conservation Area Advice
Conservation Area Advice is a focused written opinion on a specific issue; Conservation Areas is the end-to-end planning service.
Conservation Areas vs Listed Buildings
Listed Buildings covers the LBC regime for designated listed buildings; Conservation Areas covers planning controls for unlisted property within designated conservation areas.
What are the common pitfalls, and how do you avoid them?
Assuming permitted development applies
Consequence: Unauthorised works become enforcement risk.
Fix: Check both the conservation area designation and any Article 4 directions before relying on PD rights.
Non-matching materials
Consequence: Refusal under design and heritage policies.
Fix: Specify materials that match the prevailing palette of the conservation area and document the choice.
No reference to the conservation area appraisal
Consequence: Reads as generic; officer applies a stricter test.
Fix: Cite the specific conservation area appraisal and engage with its identified character.
Front elevation alterations without heritage justification
Consequence: Refusal on character and appearance grounds.
Fix: Prepare a heritage and design statement explicitly addressing the front elevation impact.
Worked example
Context
Conservation area Victorian terrace in Hammersmith & Fulham with an Article 4 direction removing PD rights for windows and roof alterations.
Challenge
An earlier scheme had been refused for excessive bulk and non-matching materials.
Approach
Vestige reviewed the conservation area appraisal, identified the prevailing rear extension typology and prepared a planning and heritage statement aligning the revised design with the borough's design guidance.
Outcome
Approved at first submission with no further revisions and no committee referral.
Which policies and statutes shape this service?
Conservation areas are designated under section 69 of the Planning (Listed Buildings and Conservation Areas) Act 1990. Section 72 imposes a statutory duty on decision-makers to pay special attention to the desirability of preserving or enhancing the character or appearance of the area. The Town and Country Planning (General Permitted Development) (England) Order 2015 reduces several permitted development rights in conservation areas, and local planning authorities can remove further rights through an Article 4 direction. NPPF paragraphs 200–208 apply to all heritage assets, including conservation areas as designated heritage assets. The local conservation area appraisal is a material consideration in every application.
