Do you need planning for a garden gym?
Like any type of garden building, a garden gym does not require planning permission as long as it meets specific requirements. Garden gyms are permitted developments, but your garden gym should be no larger than 10m x 10m, the eaves should be a maximum of 2.5 metres high, the overall height should be under 4 metres with a dual pitched roof or 3 metres with any other roof. If it is located within 2 metres of a property boundary, it should have a maximum height of 2.5 metres.
