The current trend nowadays is to create extra space in the house by doing a single storey rear extension either with a flat or a pitched roof along with patio doors.

Most houses in the UK have capacity to extend to the rear and every homeowner has a right to extend upto a certain prescribed limit. Depending on the size of the extension, the homeowner may apply for permitted development or Planning permission.Doing a rear extension to your house can be a cost effective way to increase the area of your current home as well as its value.


Do I Need Planning Permission?

Most rear extensions may be considered Lawful Development. An extension or addition to your house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions:
•    If you are planning on putting an extension within 2 metres of a boundary, the eaves height cannot exceed 3 metres.
•    If you live in an attached house (say a terraced or semi-detached house for example), the maximum depth of an extension cannot exceed is 3 metres and 4 metres in the case of detached house.
•    Assuming the rear extension is only single storey; its maximum height can be no more than 4 metres.
Planning permission will be most likely required if:
•    Materials used to build the extension are dissimilar in appearance to the existing house.
•    The proposed extension is forward of the principal elevation or side elevation fronting a highway.
•     The proposed extension has an eaves and ridge height greater than that of your property, you will need planning permission.
•    The proposed single storey rear extension (when taken with existing extensions, outbuildings and decking for example), will cover more than 50% of the land around your home.
•    You will require planning permission if you wished to add a veranda or raised platform to the structure.
Rear Extension in a Conservation Area: If you are planning a rear extension to your house in a conservation area, Planning Permission would be required prior to beginning any works. 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.
