Questions about planning in City of London
Do I need planning permission for my project in City of London?
Some house extensions, loft conversions and outbuildings can use permitted development rights in City of London, but size alone does not establish eligibility. Check the property type, previous extensions, planning conditions and the rules for the proposed work. Householder rights do not apply to flats. Conservation areas and Article 4 directions restrict particular rights; they do not automatically require an application for every change. Listed building consent is a separate requirement for works affecting a listed building's special interest.
