Our garden rooms are available in a wide range of sizes. But when it comes to the maximum size, there are limits before you need to consider planning permission. Garden rooms should be a maximum overall height of three metres, or four metres for a dual-pitched room. They should also be no larger than 10m2, and 2.5 metres is the maximum height of the eaves. There are other restrictions, and it may depend on the size of your garden, so ask us and we will let you know if you need planning permission.
