Katie Broad from Ringwood asks...

"I want to extend my home; do I need planning permission and what is permitted development?"


Architect Peter Robinson from Western Design Architects explains.....


Permitted Development
Planning permission will be required for most major additions and alterations to your home. However, there are a number of permitted development rights that allow certain works to be undertaken without the need for a formal planning application. These include, within certain parameters, rear and side extensions, porches, sheds and loft conversions as well as many more minor works. Some two storey extensions or single storey extensions as large as 8m deep could fall under permitted development, but would require the implementation of the neighbour consultation scheme and the notification of the Local Planning Authority. If objections are raised there is a chance your proposal may not be allowed.


Permitted development rights can be restricted in certain areas such as, national parks, areas of outstanding natural beauty, conservation areas or if your property is listed. They can also be removed completely through an Article 4 direction. You should have been made aware of these restrictions when purchasing your property but if you are unsure it is worth contacting your local council to advise of any restrictions that may apply to you.

What can be done without planning permission will vary depending on the type and context of the property, particularly with regard to extending.  For example detached or terraced houses will have different size limits and the distance from the boundary and whether it fronts a highway will also have an impact on what can be done. Generally if the proposals could have an impact on the public realm then planning permission will need to be sought.  


Other Approvals

Other statutory approvals such as Listed building Consent (if the works affect a listed building or a structure within the curtilage of a listed building) and Building regulations approval may still be required depending on the nature of the work.
