When a garden pool needs consent, when it doesn’t, and what changes inside the New Forest National Park.
The good news first: most outdoor pools in a private back garden don’t need planning permission at all. They usually fall under permitted development, the set of rules that lets you make certain changes to your home without applying. But there are exceptions, and around here we meet them often.
When you usually don’t need it
An outdoor pool in the back garden of a house, for your own use, generally counts as permitted development as long as it doesn’t cover more than half of the garden and any terrace or decking stays close to the ground. Pools are dug down rather than built up, so they rarely trouble the height limits.
When you do
You will need permission if the house is a listed building, if the pool is in front of the house, or if you are building a pool house or enclosure beyond the size allowed. Flats and maisonettes don’t have permitted development rights at all. Some estates and newer houses also have them removed by an earlier planning condition, so it is always worth checking the deeds.


Inside the National Park
Inside the New Forest National Park and in conservation areas, the rules are tighter. Outbuildings, including pool houses and plant rooms, are more likely to need consent, and the planning team will look carefully at trees, lighting and the view from the open forest. None of this makes a pool impossible. It means drawing it carefully and talking to the planners early.
“We have never had a pool refused. We have had plenty improved by a good conversation with the planners.”
We handle the drawings, the tree surveys and the application for you, and we will tell you on the first visit whether we think you need consent. If in doubt, we apply for a Lawful Development Certificate, which gives you written confirmation that the pool is allowed.
