The published feed does not show a live status for this application; the register on Harrow's own portal holds the authoritative version.

Householder applications cover work to an existing house and its garden, such as extensions, lofts and outbuildings, and cannot create a separate dwelling or change what the building is used for. More in our guide to planning application types.
