TGB Bentley Supreme (Storm-Braced) Apex Shed

The TGB Bentley Supreme (Storm-Braced) Apex Shed is a robust, well made garden shed from one of the UK’s best manufacturers. It’s a traditionally built British garden shed, however it features high walls, diagonal wind bracings, a 3ft wide door which is stronger than that fitted to a standard or superior shed. The TGB Bentley Supreme Apex is manufactured using Redwood Pine from well managed sustainable 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. The TGB Bentley Apex 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 Light Brown at no extra charge. You can choose from any one of 5 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 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 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 an Eco-Friendly preservative basecoat in Light Brown. 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.

Our ‘storm-braced’ sheds are very strong, and all have diagonal internal framing 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, box-framed 914mm (3ft) wide door is supplied complete with an internal lock c/w key and galvanized hinges. Doors are hinged on the RIGHT as standard (although you can request hinging on the left if you prefer). Various options are also available, such as stable doors, double doors, and various security upgrades. Please ask for details.


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, thicker roofing felt, 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.

Please ensure that regular general maintenance is carried out on all moving parts. Roofing felt should be regularly inspected, and replaced if required.
