The TGB Combi Potting Shed is a high quality, traditional sloping-fronted potting shed, however it has a 4ft deep internal storage area to the back which is accessed via an internal sliding door. It is made from high quality Scandinavian Pine, so it will withstand many years of getting wet from watering your cuttings!

All sections (roof, walls and floor) are made from smoothed, planed, interlocking tongued and grooved boards for strength and a neat finish. The Combi Potting Shed is supplied with FREE full length staging, a stable door (with choice of positions), opening window for ventilation, and toughened safety glass on the large panes at no extra charge! It also comes with 2x 4ft shelves for the storage area.

The Combi Potting Shed is supplied with an internal lock and key for security… ideal for locking away your tools, especially if you’re on an allotment! It is available in 6 sizes – 8×10 up to 12×12, however we can also make non-standard sizes if required.

Quality Construction

This garden building is manufactured using high quality, slow-growing, sustainable Scandinavian Pine from well managed FSC or PEFC 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 buildings 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 garden buildings 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 24x popular colours (maximum 2x colours per building). These look great, and don't require any additional painting immediately... please contact us for details.

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.


All products are delivered sectional/flat-packed to kerbside unless stated otherwise. *The free installation service covers most of mainland UK, however delivery to outlying areas may be subject to an additional charge, see map below.
