Building control FAQs

If you want to build a conservatory at ground level or a porch to your house, you will need to find out if you need planning permission first. You do not need building control approval if it has less than 30 sq metres floor area and you use safety glazing. A conservatory must have at least ¾ of its roof and half of its outside walls made of glass and must be separated from the rest of the dwelling by external wall and door construction. A conservatory at first floor level and a two-storey conservatory are controllable. An application is needed.

Note: conservatories are expected to be made controllable and therefore will require approval. You are advised to contact us to check if the Regulations have been changed.
