Planning appeal 3339027 at 224 Preston Hill, Harrow, HA3 9UJ (London Borough of Brent) was allowed in part (a split decision) on 12 September 2025 by Inspector Harbottle M, by written representations. The main issue, as the Inspector framed it: Whether the roof form was altered as alleged in the enforcement notice.
Without planning permission, the material change of use of the premises to a House in Multiple Occupation (HMO) and flats and, without planning permission, the erection of a part single-storey and part two-storey rear extension, conversion of the former detached garage to primary living accommodation including the installation of a bathroom, kitchen and mezzanine floor, the erection of extensions to the rear of the former detached garage, and alterations to the roof form of the premises

Main issues, as the Inspector framed them
- Whether the roof form was altered as alleged in the enforcement notice
- Whether the alleged rear extension has planning permission by reason of permitted development rights or express planning permission
What decided it
The alleged rear extension that was actually constructed was a different development from those permitted under the certified permitted development rights and express planning permission, as it combined both extensions into a single more extensive development carried out without the required permission.
