Article 4 Restrictions in Westminster

This page checks the local rule itself without assuming any particular project.

Current source position

Where the exact designation is not verified, treat the result as unresolved and check the property with the authority before relying on permitted development.

What to verify

  1. The exact property and the planning authority responsible for it.
  2. The live Article 4 direction, mapped area and schedule covering that property.
  3. The precise permitted development right withdrawn by the direction.
  4. The date the direction took effect and any later variation.
