Housing SPD

The Housing supplementary planning document (SPD) can help if you are preparing or reviewing a planning application for a residential extension or conversion. It can be used by:

  • Applicants
  • The public
  • Design professionals
  • Planning officers

The SPD encourages high quality design and dwelling standards and can help you to prepare a successful planning application. Detailed guidance for applicants undertaking rear extensions, works to basements and roof extensions are included in this document.

We have also provided further non-legal guidance on planning and other matters relating to basement extensions, which refers to the guidance given in the Housing SPD. The Planning Portal website provides the most up-to-date information on permitted development rights including an interactive householder guide.

The SPD was adopted in November 2016.
