Once you have established the external size of your conservatory, you will need to check with your local council whether your home is subject to local building restrictions.
There may be some limit to the size of the conservatory you can build if your home is a Listed Building, in a Conservation Area, or in or close to an Area of Outstanding Natural Beauty (AONB).
Developers of new property developments often include a covenant into their contract requiring their permission before extensions such as conservatories are allowed to be built. So make a check of this if it applies to you.
The overall height of your planned conservatory must not exceed four metres when it is less than two metres from any boundary. The height of the conservatory may equal the height of the house.
You will also need to measure and check whether the volume of space the conservatory takes up is within regulations. Check our advice on cubic meters for further information.
