What you must do
If an application is required, there is a choice of procedure:

	a full plans submission
	a building notice
	a regularisation

In either case you must lodge an application prior to starting work. You can be prosecuted for failing to do this.

A full plans submission requires you to complete a standard application form available from your local Building Control Office and to provide the following:-

	two copies of plans, sections, constructional details
	a site location plan and a block plan showing boundaries and adjacent buildings
	a plan fee (see Building Control Fees leaflet) and where required an estimate of cost
	for non-domestic work, a further two sets of plans showing compliance with fire safety regulations are required.

You should ensure that you use the services of an architect/agent or professional designer who has a good working knowledge of Building Regulations.
