How do you check a Hammersmith and Fulham Article 4 Direction?

On the council’s own policies map. Hammersmith and Fulham has uploaded no Article 4 areas to the national register, so the platform shows nothing — which means the data is missing, not the direction. The borough does hold 47 conservation areas covering about 959 hectares.

Where a direction applies, the removed right needs a full application at £548 instead of the £249 prior approval route.

Answers for Hammersmith and Fulham

Does Hammersmith and Fulham have an Article 4 Direction?

Yes — Article 4 removes PD for HMO conversions; restrictions on ground-floor shop-to-residential in certain streets.

What does Article 4 remove?

Article 4 removes specific Permitted Development rights — typically the right to convert a single dwelling (C3) to an HMO (C4), or office (B1) to residential (C3), without full planning permission. The right is removed only where the Direction applies.

Can I still extend my home in Hammersmith and Fulham under Article 4?

Yes. Article 4 in most London boroughs targets HMO conversions and office-to-residential, not householder extensions. Standard rear extensions and loft conversions remain available under Permitted Development unless your property is in a conservation area or is listed.

How do I check if my address is covered by Article 4 in Hammersmith and Fulham?

Check the planning portal at Hammersmith & Fulham Council or call us — we look up the Article 4 status for your specific address before quoting.

What happens if I build under PD when Article 4 applies?

If Article 4 applies and you build without planning, you face enforcement action: a retrospective application, a stop notice, or in serious cases an enforcement notice requiring reversal. Always check before starting.
