Yes — Westminster has Article 4 Directions in force. Multiple Article 4 Directions — office-to-residential restrictions, HMO conversions, retail to residential in shopping zones. Article 4 removes specific permitted development rights that would otherwise apply, meaning full planning permission is required where PD would normally be sufficient. We check Article 4 status for your specific property before quoting.
Westminster has 56 designated conservation areas, including Mayfair, Belgravia, Marylebone and others. Planning applications within conservation areas require additional heritage consideration and often a Heritage Statement.
