Article 4 directions in London Borough of Hounslow

London Borough of Hounslow has published 3 Article 4 direction areas in force to the national planning dataset (planning.data.gov.uk), as of our last update on 25 October 2026. 1 of them withdraws Class L — the change from a house (C3) to a small house in multiple occupation (C4) — according to the council's published record. 2 records do not say which rights it withdraws.

The national dataset holds what councils have published to it, so a recent direction may be missing — confirm with the council before relying on permitted development. An Article 4 boundary can split a postcode: check the exact address with the council.

Class L is Schedule 2, Part 3 of the General Permitted Development Order 2015; a small HMO (use class C4) has not more than six residents. A direction withdraws only the classes it names, so other changes of use may still be permitted development here — the source record shows what the council published.

Other Article 4 areas in force

0 records list the classes withdrawn without Class L; 2 records do not say which rights it withdraws. Codes such as 1A or 2C name the permitted development classes withdrawn (Part and Class of Schedule 2).
