Questions about planning in Kingston upon Thames
Do I need planning permission for my project in Kingston upon Thames?
Some house extensions, loft conversions and outbuildings can use permitted development rights in Kingston upon Thames, 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.
