Imagine a garden shed that completely protects your valuable tools and bicycles, enjoys a storage-friendly design, and comes with a marvellous 20-year guarantee. Well, the 8x8 Biohort HighLine H4 Dark Grey Metal Double Door Shed offers you all this and more.

This metal shed is hand-pressed from high-tensile, hot dipped, zinc and polyamide-coated galvanised steel plate, so is robust, durable and resistant to rust. This not only makes for a superior garden shed, but one that is perfect for use on a caravan park too, where non-combustible storage sheds are compulsory.

The flat roof is made from the same high-specification material and has an exceptionally impressive snow-load capacity, ensuring your stored items receive complete weatherproof protection, the whole year round. Furthermore, the roof's integrated guttering system, which includes useful leaf traps, offers a free and sustainable source of water for your garden plants.

You gain storage-friendly access to this garden shed via wide double doors, which are fitted with a gas-assisted spring damper that ensures extra-smooth opening and closure. These doors also boast an extra-secure 3-way locking mechanism, including a cylinder lock and 2 keys, so rest assured that your prized possessions will be safe from unwanted attention.

Once inside, the invaluable integrated organisation system, comprising of a shelf set and tool hanger, allows you to keep everything tidy and to-hand. A superb feature, the acrylic fanlight, which is near-unbreakable and stretches around the shed's entire perimeter, provides ample natural light for you to work.

With dimensions of 222cm x 275cm x 275cm, including overhang, this metal garden shed is completely maintenance-free, saving you money and leaving you more time to do the things you enjoy. To top it all, every single painted-part has been coated on both sides, which makes for a handsome appearance.

Don't be concerned about the difficulties sometimes associated with assembling metal sheds, for this model is assembled via a modular plug-in system, designed to reduce the number of screws required and simplify the whole process.

**Please be advised that this garden shed is supplied without a floor and that you MUST anchor it to a level concrete, paved or timber base. An anchor kit is included to facilitate this. **

To add stability to your shed and to help you add your own flooring if you so wish, you can purchase an aluminium floor frame as an optional extra. Together with the ground anchors, this ensures that the shed remains completely secure during adverse weather conditions. The floor frame comes with 4 plastic corners, so fits the shed perfectly and allows you to build your own shed floor. Alternatively, an aluminium chequer-plate floor with connecting rails is available for you to buy as an optional upgrade to add to the frame. For a full shed floor, purchase both the frame and floor panel, then support the latter with a suitable filling, for example 2-3cm of XPS rigid foam board (filling not included). Please be advised that you MUST not purchase the floor without the frame.

Why not buy some other optional extras to customise your new garden storage shed too? Available upgrades include a 2-piece shelf set, BikeMax bicycle holder and threshold access ramp.

We stock models of this shed, boasting exactly the same premium specifications, in silver, with double doors and in a range of other sizes.
