Planning guide
Article 4 directions explained
An Article 4 direction can require planning permission for work that might otherwise be permitted development. The exact area, property, rights removed and effective date must be checked against the authority’s direction and mapping.
At a glance
Key facts
- Effect
- Specified permitted-development rights may be removed
- Evidence needed
- Direction, schedule, map and effective date
- Do not assume
- Every property in a conservation area is affected identically
A reliable process
How to approach the question.
- 01Check whether the exact property falls inside a mapped direction.
- 02Read the schedule to identify which classes of development are restricted.
- 03Check the effective date and any later variation or cancellation.
- 04Confirm the route with the authority or a planning professional before relying on permitted development.
Worked example
Replacing front windows
A direction may target alterations to front elevations while leaving other rights unchanged. A map match alone is therefore insufficient: the schedule must be read to see whether the proposed windows are within scope.
What this does not prove
- Open designation datasets can have incomplete authority coverage.
- Boundaries and schedules may be published separately.
- A nearby Article 4 feature is not the same as a confirmed on-site restriction.
Method used
- Confirm the subject property and distinguish applications at the address from wider local context.
- Classify proposal type and outcome consistently, keeping pending, withdrawn and approved-with-conditions cases separate.
- Give more weight to recent, similar and well-documented decisions; retain contradictory evidence rather than hiding it.
