Not all extensions require Planning Permission. Under new rules that were introduced in October 2008 some extensions are permitted without the requirement to submit a formal planning application as it is granted automatically Under "Permitted Development Rights". Although Permitted development rights are intended to be universal across all local authorities as they derive from a general planning permission granted by the government, interpretation by local authorities may vary. 

There are certain limits to extensions which one can build under permitted development. Adding an extension to your home will be considered permitted development, not requiring  planning permission, subject to it meeting the following restrictions:

At Drawing and Planning, we are well aware of what is likely to be granted in each particular borough and always bear this in mind when compiling our designs for your extension.

We offer a standard Permitted Development Package which covers all the elements you will require to gain approval to build an extension.

Please note: Permitted Development rights only apply to houses and do not apply to flats, maisonettes or other buildings. you will need full planning permission for all works to a Flat or Maisonette. read more..

Permitted Development in a Conservation Area

If your property is in a conservation area, your permitted development rights are more restricted than other properties.  

Under your permitted development rights, an extension to a property in a conservation area is restricted to being a single storey rear extension, cannot include any side extension or exterior cladding.

It is very possible that your proposals for an extension will not meet all the restrictions to be considered permitted development. You may want to extend to a greater depth than the allowance permits, perhaps you are thinking of creating a front facing dormer or extension. You could also be considering the addition a raised decking platform, a balcony or a veranda to complement your extension. In whichever way your plans may differ from the restrictions, even the use of alternative materials; you will require planning permission prior to commencing any works on your extension.

Extensions Exceeding Permitted Development

An Extension will require Full Planning Permission where:

Flat or Maisonette

The planning regulations for flats and maisonettes differ in many important ways to that which covers houses. If you plan to build an extension for a flat or maisonette you will most likely require full planning permission even it your proposals are within the permitted development restrictions. this is because the rights do not apply to maisonettes and flats. More on Flats and Maisonettes

Building an extension in a Conservation Area

If you have lived in a conservation area for some time you are likely to be aware of the regulations and how these can affect home improvements. However if you have recently moved into the area it is most likely to be all new to you. That being said, one of the reasons that you purchased your new home may well have been the character of the area and the preservation the conservation status has provided. It is important to note, Conservation areas are not intended to lock an area in the past as a form of living museum, new development is often permitted but it will have to be undertaken sympathetically to conform to the existing environment. In a conservation area you will require planning permission for most extensions. It is absolutely necessary to obtain the required conservation area consent prior to beginning any works. Going ahead without this may result in a fine or imprisonment, or both.
