Frequently Asked Questions

New Builds and extensions

Do I need permission to build a garage extension onto my home?

Yes you do require permission to build a garage onto your home however a carport extension, open on at least two sides and less than 30m2 in floor area, is exempt. You should ensure a carport does not interfere with the proper working of a low-level flue outlet from an oil or gas appliance.

Do I need permission to build an extension to my home?

Normally you would need permission to build an extension to your home however if you are building a ground level porch or conservatory under 30m2 in floor area this is generally exempt provided the glazing complies with the safety glazing requirements of the Building Regulations.

You should not construct a conservatory where it will restrict ladder access to windows serving a room in the roof or a loft conversion, particularly if any of the windows are intended as a way of facilitating escape or rescue if there is a fire. Additionally you should not construct a conservatory over a public sewer without the permission of the water authority.
