The Latest Garden Rooms By Green Retreats
Basebox is the latest garden room design from Green Retreats, and takes over from Garden Studio as our most cost-effective quality garden room.
Garden Studio is now discontinued to make space for this new Basebox design which offers better value for money vs quality using the latest in innovative materials.
If you’re still looking for the Garden Studio designs we will be honouring orders for a limited time only. To see the details of the Garden Studio range from Green Retreats and Costco, please contact us.
