Please Note.
This information is a guide only. Existing house means the original house, the way it was built to start with. Changes to the original house could have been made before by other owners. Sometimes it is hard to tell if a house has been extended or altered in any way.

Please refer to your house deeds and other information held inside the property archives within your local council to double check everything before you proceed with any Permitted Developments.

Builders GB do not take any type of responsibility and have provided this information in good faith and as a guide only. More detailed and precise information is freely available from your Local Council.
