Planning Permitted Development

With certain domestic house extensions and outbuildings, planning approval is not necessary as long as one complies with certain size or dimensional criteria. This allowance is known as Permitted Development.

Details of these criteria can be found on the government’s Planning Portal website as follows:

If for any reason it is unclear as to whether a project falls within Permitted Development, this can be formalised by us with an application known as an ‘Application for a Lawful Development Certificate for a Proposed use or Development’.
