One of the most popular ways of expanding a home is to add a side extension to the property. It can be a single storey side extension or can be a double storey depending on various factors. A side extension can have a flat roof or pitched roof depending upon the design of the original house .Depending on the size of the extension, the homeowner may apply for Planning permission.

If you live within any area that enjoys a statutory designation such as a conservation area or national park, do remember that it will not be possible to build a side extension without planning permission.


Do I Need Planning Permission?

It is most likely you will require planning permission if you are planning to build a side extension to your house. As per the latest planning legislation an extension or addition to your house is considered to be permitted development, not requiring an application for planning permission if it fulfils the following criteria:
•    No extension forward of the principal elevation or side elevation fronting a highway.
•    On designated land no side extensions. Designated land includes conservation areas,national parks and the Broads,Areas of Outstanding Natural Beauty, and World Heritage Sites.
If your side extension does not fall in the above categories then it is likely that Planning Permission will not be required if:-
•    The extension to the side of the property is only single storey and no higher than 4 metres and no wider than half the width of the original dwelling house.
•    Materials must match the existing.
•    No more than 50% of your private garden area can be built upon. In this calculation, you must include any outbuildings that already exist here.
Side Extension in a Conservation Area: If you are planning a side 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.
Side Extension in Flats or Maisonettes: If you live on a ground floor flat and plan to add an extension to your flat you must apply for planning permission. If your flat is a listed building it is likely you will need listed building consent and you should contact your local planning authority for advice before you start work.
Please note that works to a listed building that affect its special historic character without consent is a criminal offence.

Do I Need Building Regulations?

Yes, you do need Building Regulations to build a side extension.
