Altering your home
If you want to alter your home or add an extension, check whether you need planning permission or building control approval before you start.
You may need planning permission if you are:
- extending your home by constructing an extension or a dormer window
- putting up a garage
- putting up a boundary fence or wall
- extending your garden onto adjacent land
- hard paving the front of your garden
- putting up outbuildings or garden structures, such as a summer house, shed or swimming pool
- having a wind turbine installed
You can find detailed guidance on when you need planning permission on the Planning Portal.
Work that usually requires a building control application:
- extensions
- loft conversions
- new buildings
- removal or alteration of a load-bearing wall
- installation of sanitary applications such as baths and toilets
- underpinning
- removal of a chimney breast that requires structural support
- cavity wall insulation
- installation of replacement windows
- change of building use
You will not normally need to apply for building control approval if you are constructing:
- a porch
- a conservatory
- a detached garage or shed
- a carport
- a covered walkway
- a greenhouse
- a temporary building
You can find detailed guidance on building control for specific projects on the Local Authority Building Control website.
