What Article 4 restricts in Hammersmith and Fulham, how it affects extensions, lofts and HMOs, and how to plan around it.
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.

In detailYes — Article 4 removes PD for HMO conversions; restrictions on ground-floor shop-to-residential in certain streets.
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.
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 designation changes a Hammersmith and Fulham scheme inside an Article 4 area: Hammersmith & Fulham Council maintains 45 conservation areas, including Brackenbury Village, Fulham Palace Road, Parsons Green.
