Permitted Development  Extensions - Oct. 1st 2008.

Extensions for permitted development to domestic dwellings fall under class A of the GPDO in most cases. There is other criteria for extensions to a dwellings roof for example but this section will simply concentrate on permitted development for home extensions.

The PD rules have changed from a building volume or area based assessment to a more impact based assessment which now has dimensional limits one can extend a property usually from the original rear or side elevation of the existing dwelling house wall.

This combined with eaves & roof heights limits & minimum distances to boundaries make for a more reasonable assessment of what the permitted development rights are for extensions. This does allow greater freedoms for people who wish to install extensions to their properties without the need for Planning Permission but the dimensional limits and physical size of what you can do under the PD rules needs to be fully understood.

Another major trap that can make your extension fall outside of the Permitted Development allowances is the fact that the 4M & 3M maximum projection distances for single and two storey extensions relate to the ‘original’ house wall. Therefore if you are intending to extend from a previous extension wall no matter how old, then you will probably fall outside of the PD rules and require formal planning consent.

Side windows on the upper floor the permitted development extension are also prevented unless they are obscure glazed and any opening sash must be at least 1.7M above the floor level which is a new restriction compared to the previous permitted development rules.
