TGB Groundsman (Storm-Braced) Pent Shed

The TGB Groundsman (Storm-Braced) Pent Shed is an immensely strong garden shed from one of the UK’s best manufacturers. It’s a traditionally built British garden shed, featuring free double-doors upgrade, high walls, diagonal wind bracings, and ultra-heavy 75x50mm framing. The TGB Groundsman Pent is manufactured using Scandinavian Redwood Pine from well managed sustainable forests, and is available in 9 sizes – 8×6 up to 12×10. 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. 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 10x door positions at no additional cost. An optional timber workbench is available with this building.
Our TGB 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

The TGB Groundsman is made using EXTREMELY STRONG 75x50mm (nominal) framing. The entire 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 an Eco-Friendly preservative basecoat in a choice of two colours – Red Cedar or Light Brown. Ultra-strong 75x50mm nominal (70x44mm finished) 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.

Our Storm-Braced sheds are very strong, and all have diagonal internal bracings on the walls to help the building withstand the effects of storm-force winds. Unfortunately mother nature can be very cruel at times, therefore we aren’t able to guarantee any shed against extreme weather conditions, however these buildings will definitely last much longer than standard models.



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 12x popular colours (maximum 2x colours per building). These look great, and don’t require any additional painting immediately… please contact us for details.

Doors, Locking System & Windows

A single 760mm (30″) door or a free double door 1220mm (4ft) wide door is supplied complete with an mortice lock c/w keys and galvanised hinges. Sheds up to 10ft in length will have up to 3x (2x fixed + 1x opening) glass windows as standard, however 12ft long sheds will have up to 6x windows (4x fixed + 2x opening).



Professional Assembly Included

We will install your TGB garden building at NO ADDITIONAL CHARGE although some geographical limitations apply. Our PROFESSIONAL ASSEMBLY SERVICE covers approx. 90% of the UK mainland population, and requires non-restrictive access and a suitable base/site.


DIY Assembly Video

Assembling your building yourself can be very satisfying and it has several advantages: you probably won’t have to wait as long for delivery, you can assemble it on a day suitable to you, you can pre-treat the panels beforehand allowing the best possible protection for your building, and we may even be able to offer you an additional discount so you’ll save even more money! 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 garden building 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, verandahs, log-lap cladding, toughened glass etc. The building can also be made to a bespoke size or configuration… please call for details. A solid timber workbench (852 x 1650 x 635mm) is available as an optional extra.
