What does it mean?
Below is a brief explanation of the three main terms that you will hear when starting a building project.
Permitted Development is your right to carry out specific building projects without the need for Planning Permission.
You can use your permitted development rights to build:
A loft conversion within the original external walls. The ridge height of the roof cannot be raised.
A single storey extension up to three metres for a semi-detached or terrace house and four metres for a detached house. The measurement is taken from the back of your house towards the end of your garden. The highest point of the roof cannot exceed four metres.
There is also the Neighbour Consultation Scheme which extends your permitted development rights. More information on the Scheme can be found here.
Your local Council’s planning department are responsible for granting planning permission and there is a fee involved.
You need this if you want to build:
A loft conversion where the ridge is to be raised or the roof is to be extended beyond the original external walls of the property (such as over a side extension).
a two-storey rear extension
a single storey extension that projects more than 3 metres from the back of your house for a semi-detached or terrace or 4 metres for a detached house.
An extension to the side or front of your property.
All the above building work is subject to Building Regulations. The regulations ensure that any work carried out is safe and fit for purpose. An application needs to be made to the local building control office. There are also approved contractors that can do this for you so you have a wide choice of providers.
