Quality Construction

This garden building 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 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. Heavy duty 40kg 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.

Both are supplied complete with heavy-duty, hook & band galvanized hinges, and internal locks with 2x keys as standard. This building features joinery made windows featuring a combination of fixed and opening panes. The single door can be positioned anywhere around the building, however this must be decided at the time of order.

Please Note: The side door will have it’s hinges fitted on the right side of the door unless stated otherwise.


Professional Assembly Included

We will assemble your TGB heavy duty garage 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.

Look out for the FREE INSTALLATION logo:


Please note: we don’t include a fixing-down service as part of the assembly, however we do recommend taking the concrete anchor bolts (optional) to do this yourself, as any open structure can be moved (or possibly damaged) by severe winds.


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.

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.
