Treetop - Stormproof Heavy Apex Shed
Treetop's Traditional Heavy Apex Sheds are one of the best quality sheds available in the UK. They are built to
a very high standard using redwood pine shiplap and smooth planed & chamfered interior framing. Diagonal storm-proof bracing frames will ensure that the shed remains solid against strong winds. These buildings are manufactured throughout with quality tongued and grooved timber, and come with mineral roofing felt, glass windows and an internal lock-and-key.

Our Treetops Traditional Heavy Shed range features 22 sizes - 8x6 up to 20x12. Each model is manufactured with 12mm boarding (19mm optional), and glass windows are supplied as standard. No chipboard, OSB, or inferior sheet materials have been used, and the walls, roof and floor are all made from treated tongued and grooved interlocking pine.

Why Choose Treetops Traditional?

Q - Why choose Treetops Traditional when there are so many other buildings on the market?

A - Treetops Traditional Buildings come in hundreds of different styles and sizes, and because they are made to order (and aren't stockpiled), they can be your own requirements by choosing one of the many options available, such as double doors, heavy floors etc. All models are manufactured to a high standard using good quality materials. The high quality preservative used is the best available on any factory-treated building.

Quality Construction
All buildings are manufactured using 45x45mm framing throughout with diagonal bracing on some models. Standard workshops come with 12mm thick shiplap cladding, but a 19mm option is available. A combination of fixed and opening glass windows are supplied as standard.

Quality Preservative
All sheds in the Treetops Traditional range are treated inside and out with a high quality preservative colour treatment. *Due to recent legislation, the preservative compound used has recently been changed to an eco-friendly LOW VOC treatment. The colour shade will change slightly. Updated images are currently unavailable, however please feel free to contact us if you require any further information.

Doors and Locking System
Standard 30" wide doors are supplied as standard, but double doors can be fitted. All are supplied with an internal lock with key. The doors have extra framing which improves strength and combats excess twisting and warping.

Straight-forward Assembly
These buildings are supplied in an easy to assemble flat-pack. Only basic tools are required, and no professional experience is necessary. Normally 2 people can usually complete the job in 2-5 hours, but an erecting service is also available at an extra charge (depending on your area) if required. Please ask when placing your order.

*Our professional erecting service may not be available your area, and may be subject to additional charges if you are in an outlying area. Certain areas of mainland Scotland will be subject to an additional delivery charge. Please check for exact costs before ordering. We cannot specifically guarantee any garden building against excessive natural occurrences, however these models are designed to remain much stronger than standard garden sheds during storm-force winds (especially if upgrading to 22mm nominal weatherboarding, and/or 75x50mm framing option).

All products are delivered sectional/flat-packed to kerbside unless stated otherwise. Delivery times and sizes given are approximate and are intended only as a guide, you should contact us prior to purchase if you have any queries regarding the dimensions or if you require precise sizes (although please note that we are unable to be exact as manufacturers allow a tolerance of +/- 1.5mm when machining). Please read our terms and conditions before ordering. For a long lifespan, you should treat your timber products regularly with a high quality preservative. Moisture dictates the amount that wood expands and contracts, and natural cracks and knots may appear. This is a completely natural occurrence which gives wood it's unique character, and is not be classed as an imperfection or flaw. Generally, plastic or metal sheds are not supplied with a floor as standard, and may be prone to condensation.
