What are the extra costs for a garden room?

There may be some extra costs when it comes to designing your garden room. Let’s break it down so you don’t encounter any hidden costs or surprises when you come to order.


Groundworks and Base

  The base for your garden room is NOT included in your price and is an extra cost that will be added on, whether you choose to have concrete or ground screws for your garden room. The price starts at £1,780 and varies depending on the size of your garden room, which can be determined at your FREE site consultation. We also offer groundworks services at an additional cost to remove any pre-existing sheds, small trees or plants. 



For your garden room, our electrical connection services are an extra cost within your quote and price. Likewise to the groundworks, the electric fittings will be cost dependent on the size of your garden building. However, our prices start from £1,540.


Planning permission

 If your garden room project needs planning permission, we offer planning services to our customers. Household application is £707 and full application is £882 for planning. Not every garden room will need planning permission, find out if your building needs planning by reading our other blog post: Planning permission. 



 Previously mentioned earlier in the blog post, FREE delivery for your garden room is included within 50 miles of our factory based in Thurston, Suffolk. However, anything over this will be at an additional cost. You can enquire further by speaking to our friendly sales team, just simply call us on 0800 242 5559.
