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.Contact Us

Delivery & Installation
Full installation and delivery all included in the quote for your building. What's more, delivery is included in Band 1.
Obstacles & Boundaries
Make the most of your garden space. We can build as close a 400mm to any obstacle or boundary when constructing your garden studio building.
The design of our garden buildings means that, in most cases, you will not require planning permission, saving you time and hassle.
We use industry-leading, 'extra clear' double-glazing as standard for our garden buildings' window and door options.
Low To Zero Maintenance
Basebox is completely maintenance-free. The garden room will need painting within 6 months of purchase – then that's all!
The eco-polymer foam insulation used in every Basebox building makes it fully insulated for year-round use.
10 Year Guarantee
Inclusive 10-year comprehensive guarantee. By using the finest materials, we estimate a minimum 30-year life.
