What this refusal means

Merton refused this application for the reasons on the decision notice; only the applicant can appeal, and refused schemes often return in revised form. More in our guide to what happens after a planning decision.

About householder applications

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.
