Quality Construction

The TGB Sunflower Pent Potting Shed is manufactured using high quality, slow-growing, sustainable Scandinavian Pine from well managed, sustainably certified forests.

All models are constructed using 16mm nominal (approx. 12mm finished) tongue and groove shiplap timber walls, along with tongue and groove roofs and floors, however this can be upgraded to a massive 22mm nominal thickness (approx. 18mm finished) if required. Please note that NO chipboard or OSB is used in the construction of ANY TGB building.

These TGB Sunflower Potting Sheds are supplied pre-treated with a Light Brown Eco-Friendly preservative basecoat. Strong, smoothed, rounded and planed framing has been used internally, which is doubled at the corners for extra strength. Standard 20kg grade mineral roofing felt is supplied to keep the roof watertight, however this can be upgraded to 40kg if required.



TGB Sunflower Potting Sheds are supplied pre-treated with a quality brown, non-toxic preservative base coat. This ensures that your garden building is ready to accept any preservative colour of your choice.

Alternatively we can supply them made from long-lasting Tanalised pressure-treated timber with a 15-year anti-rot warranty, or you can have your building factory-painted in a choice of 12x popular colours (maximum 2x colours per building). These look great, and don’t require any additional painting immediately… please contact us for details. Please remember that the colours shown below will look slightly different on your device, and from batch to batch.

Please contact us prior to purchase if you have any queries regarding the dimensions. Sizes shown above are finished sizes (not nominal), however you should note that the roof will extend beyond the Body Size shown above.

Information shown above has been supplied by the manufacturer, and is as accurate as possible (errors and omissions excepted), however it is intended only as a guide. This high quality building has an expected lifespan well in excess of 15-years. We recommend that you install the building on a solid, free-draining base, with at least 60cm free space all around for maintenance and to avoid splashback.

You should treat all sections with a high quality, spirit-based preservative prior to assembly, and subsequently every year in accordance with the manufacturers instructions. Please ensure that regular general maintenance is carried out on all moving parts, and that the roofing felt is regularly inspected, and replaced if required.
