Most outbuildings in England do not need planning permission. Garden sheds, workshops, home offices, and similar structures can usually be built under permitted development rights.
Permitted Development Limits
- Located in rear or side garden, not front garden
- Total area covered by outbuildings does not exceed 50% of the garden
- Single storey with maximum eaves height of 2.5 metres
- If within 2 metres of a boundary, maximum overall height is 2.5 metres
- If more than 2 metres from boundaries, maximum 4 metres for dual pitched roof or 3 metres otherwise
- Not used as a separate dwelling or sleeping accommodation
- No veranda, balcony or raised platform
Home Offices and Garden Rooms
A garden office is treated the same as any other outbuilding. As long as it meets the limits and is used as a home office rather than a dwelling, it is almost always permitted development.
