TGB Groundsman Apex Shed (Storm Braced)

tgb lead timeThe TGB Groundsman Apex Shed (Storm Braced) is an immensely strong garden shed from one of the UK’s best manufacturers. It’s a traditionally built British garden shed, featuring double-doors, high walls, diagonal wind bracings, ultra-heavy 75x50mm framing and this apex model also has ultra-heavy roof trusses.

The TGB Groundsman Apex shed is manufactured using Scandinavian Redwood Pine from well managed sustainable forests, and is available in 9 sizes – 8×6 up to 12×10.

TGB Groundsman Apex 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.

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 5 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 Apex Shed is made using EXTREMELY STRONG 75x50mm (nominal) framing. The entire building is manufactured using high quality, slow-growing, sustainable Scandinavian Pine from well managed, sustainably certified forests.

All Groundsman 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.

These TGB Groundsman Apex Sheds are supplied pre-treated with an Eco-Friendly Light Brown preservative basecoat. 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 TGB Groundsman Apex Storm-Braced sheds are very strong, and all have diagonal internal bracing 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 Groundsman Apex 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.
