Why you should get expert advice on your permitted development single storey rear extension?

An extension or addition to your house is considered to be permitted development, not requiring an application for planning permission, provided certain limits and conditions are met.

Those conditions are:

Extensions (including previous extensions) and other buildings must not exceed 50% of the total area of land around the original house. The term ‘original house’ means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.
* Sheds and other outbuildings must be included when calculating the above 50% limit.
On designated land side extensions are not permitted development. On designated land and Sites of Special Scientific Interest the regime for larger single-storey rear extensions which runs until 30 May 2019 does NOT apply.
Materials used in exterior work to be similar in appearance to those of the exterior of the existing house. This condition does not apply when the extension is a conservatory.
If extension is within two metres of a boundary maximum eaves height should be no higher than three metres to be permitted development.
Single storey rear extension must not exceed a height of four metres.
Maximum eaves and ridge height of extension no higher than existing house.
