This application is at appeal, which passes the decision from St Albans to the planning inspectorate, and the outcome will replace the council's decision. More in our guide to what happens after a planning decision.

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.
