Planning permission isn't normally required for outdoor swimming pools. An outdoor pool is considered by planning authorities to be a 'garden project' but you should check with your local authority just in case. There may be additional restrictions if your property is:
- In a national park
- On greenbelt land
- In a conservation area
- On designated land
- In a listed building
There may also be legal covenants attached to your property.
The building that houses an indoor pool is normally classed as a 'permitted development' which does not need a planning application, depending on previous development on your property and subject to the following conditions:
For the purposes of planning, outbuildings must be a single storey. The eaves should have a maximum height of 2.5 metres and a four metre maximum overall height if there is a dual pitched roof or three metres for any other roof.
No verandas, balconies or raised platforms (a platform must be no higher than 0.3 metres) are allowed on the building. This includes decking – decking above 0.3m requires Planning consent.
The building can only be a maximum height of 2.5 metres. The outbuilding cannot be situated on land forward of a wall forming the principal elevation (in front of the house). Only half the area of land surrounding your house should be covered by buildings or other additions.
Contact your local planning office before starting work on the project.
