Construction of new buildings and extensive changes to existing buildings usually requires consent from the local planning authority in the form of planning permission. This planning system is designed to control inappropriate development.
In certain circumstances you may be able to extend your home using permitted development rights. This is a term used to describe proposals that do not need planning permission. Great care should be taken as these rights are often difficult to interpret.
The majority of building projects are required to comply with the Building Regulations which ensure the health and safety of people in and around all types of buildings. They also cover energy conservation, and access and facilities to buildings ensuring they can be used by everyone.
LISTED BUILDING CONSENT
Listed building consent is required for all works of demolition, alteration or extension to a listed building that affect its character as a building of special architectural or historic interest.
