Our House Extensions Supplementary Planning Document (SPD) will benefit householders and their agents when planning extensions and houses' alterations.

It illustrates the criteria which the Council will usually apply in assessing proposals for house extensions. 

The House Extensions SPD will benefit residents, ward councillors and Parish Councils interested in developments in their area. It provides advice regarding designing domestic extensions to ensure that the neighbourhood character and amenity are maintained. 

We adopted our current House Extensions Guidelines in 2003. While it's a useful and well-used document, it is now out-of-date. It requires revision to reflect current national and local policies better. This clarity will improve assurances to applicants on the likely acceptability of proposals before submission and, in turn, will allow officers and councillors (through the Development Management Committee) to make more robust decisions.  

Therefore, we're proposing to introduce a new, revised set of householder extension guidelines. The current, existing document contains a lot of relevant guidance, so we're not re-writing the whole document. Instead, we're making revisions that will bring it up-to-date.

Benefits of updated householder extension guidelines

  • Revising the guidelines provides the opportunity to reflect better issues that are being dealt with daily by our Development Management Team.
  • It provides the opportunity to consolidate advice for householders by, for example, including more information on issues such as parking standards, trees and heritage matters. 
  • Applicants will be able to submit with more confidence that their proposals meet with the guidance. 
  • Our officers will have a firmer basis for their recommendations to ensure good quality, sustainable development.
  • It will reduce the need for negotiating improvements to proposed developments, as all parties will have a more specific, up-to-date document.
  • It will provide confidence to those involved in the planning process that the right decisions are being reached.
