Some garden projects will need to apply to the local planning authority for planning permission prior to commencing any works. However, there are several scenarios where planning permission may not be required*. As a guide, outbuildings are generally considered to be permitted development, without the need for planning permission, subject to certain conditions. For example:
- Outbuildings must be single-storey with a maximum eaves height of 2.5 metres and maximum overall height of 4 metres with a dual pitched roof
- For outbuildings within 2 metres of the property boundary, maximum height is 2.5 metres
- Verandas, balconies or raised platforms are not permitted
- No more than half the area of land around the original house should be covered by additions or other buildings
- If your property is a listed building, on designated land or within a national park, further restrictions apply
