What’s the Maximum Size for a Garden Room Without Needing Planning Permission?
If you’re planning to build a garden room, you may not need planning permission as long as it meets certain conditions. Generally, it must be single-storey and no taller than 2.5 metres if within 2 metres of a boundary, or up to 4 metres if further away. Additionally, the total area of outbuildings cannot cover more than 50% of your land. However, if you live in a listed building or conservation area, or if the room is intended for sleeping, different rules may apply. Always check with your local planning authority to confirm the guidelines.
