Extensions to Residential Dwellings

Building Extensions and Permitted Development

A building extension is often a cost effective method of adding value and function to a home. In order to erect an extension without Planning Permission, the following should be adhered to. It should be noted that any other design concept beyond these can still be accepted within reason.

New Planning Policy for extensions (as of 30th May 2013)

The new planning policy changes include an increase in the permitted development rights relating to single storey extensions and applies to residential and business owners (excludes conservation and AONB areas). Below details the original requirements for permitted development, however for the next -1031 days, extensions of up to 8 metres (for detached buildings) and 6 metres (for attached buildings) are now possible without formal Planning Permission. There is a stipulation that proposals are submitted to the local authority, who will then notify adjoining neighbours for any objections. Neighbours have 21 days to raise an objection to the proposals.
