TGB Superior Pent Shed

tgb lead timeThe TGB Superior Pent Shed is a good quality, well made garden shed from one of the UK’s best manufacturers. It is made to the same robust, traditional British quality as the TGB Superior Pent shed, made using Redwood Pine from well managed sustainable forests, however it is much taller.

All TGB Superior Pent Sheds 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.

The TGB Superior Pent Shed is available in 11 popular sizes – 4×4 up to 12×8, all combining traditional style with an unbeatable price. Our range of TGB buildings are available pre-treated in a Honey Brown preservative at no extra charge. You can choose from any one of 10 door positions at no additional cost, as well as one of the many options that are available for this range, including double doors, stable doors, opening windows, and additional security… please call for details. Our TGB Superior Pent Sheds product range is second to none, featuring hundreds of great quality buildings, accessories and optional extras, however it is difficult to show everything fully on a single web page. We are an OFFICIAL PREMIER STOCKIST of all TGB products, therefore you are welcome to visit our Edinburgh display site to see the buildings in person.

Quality Construction

This TGB Superior Pent 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 buildings are supplied pre-treated with an Eco-Friendly preservative Light Brown basecoat. Strong, smoothed, rounded and planed framing has been used internally, which is doubled at the corners for extra strength. Mineral roofing felt is supplied to keep the roof watertight.



TGB Superior Pent 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.

DIY Assembly Video

TGB Sheds, Playhouses and Summerhouses come with all the fixings and fastenings you need, but to make things even easier, here is an installation video that you can follow showing the assembly of a typical TGB building.




Optional Extras

This TGB Superior Pent Shed is supplied as a full kit, complete with all necessary fixings, fastenings, glazing and roofing materials. Optional extras include professional assembly, framing and wall thickness upgrades, double doors, opening windows, heavy flooring, verandas, log-lap cladding, toughened glass etc. The building can also be made to a bespoke size or configuration… please call for details.

This TGB Superior Pent shed has an expected lifespan 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. Roofing felt should be regularly inspected, and replaced if required.
