Guidance for residential properties

Guidance for residential properties

The Planning Portal gives advice on whether planning permission is needed. The Portal's interactive house guide for terraced or semi-detached houses provides visual guidance and information on permitted development (extensions, conservatories, loft conversions, outbuildings and porches). 

Any definitive view on whether a planning proposal is acceptable will need to be the subject of a planning enquiry and should be submitted on the 'planning enquiry form' with plans and the relevant fee.

If you are considering making an alteration to your home please see our web pages on Pre-application advice and the Planning Duty Rota.
