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. For security, an internal lock c/w key is fitted as standard, and mineral roofing felt is supplied to keep the roof watertight.


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.

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.

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 Scotland and England, however delivery to outlying areas may be subject to an additional charge, see map below.

Delivery lead time shown is typical for most areas, however this is approximate and cannot be guaranteed. Assembly will add an average of 1-2 weeks to your lead time, therefore please check before ordering if delivery time is critical. Buildings supplied with a non-standard option or bespoke sizes cannot be returned under any circumstances, therefore please ensure that you order correctly. We're here for advice if you're not sure!

Reviewer: Erinn Mackay from Thurso, Caithness   5 Stars

We are absolutely delighted with the summerhouse... There is nothing better than to get the housework done in the morning, dinner organised, then I am away out to the wee hoosie for the rest of the afternoon. I either read, or have a wee snoozy! Great life. I've spent many hours in the "wee hoosie" since it was installed. Thanks for all your help.
