Take a look below at our garden potting sheds in a variety of styles. Our broad range of high quality 12 & 15mm tongue and groove garden potting sheds are available in a variety of different styles and sizes and all come with a standard water based treatment. However , we always recommend upgrading to our PREMIUM TREATMENT option where you can choose from a range of colours. We also recommend protecting the bottom of your shed by adding a tantalised timber base to your order. This helps protect the bottom of your building and lifts the building off the ground whilst offering a complete seal around the base of the shed.
