20ft x 12ft Heavy Duty Apex Garden Shed

Write the first review


As the largest in the range, the 20ft x 12ft Heavy Duty Apex Shed offers many opportunities for gardeners and DIYers alike. With so much room for the storage of large gardening equipment, there's also space to work on various other projects.

Heavy duty isn't a phrase that's used lightly. The materials in its construction are excellent quality and highly durable. Scandinavian timber is used throughout instead of chipboard while traditional coach bolting and galvanised nails are favoured rather than pins and staples.

The sturdy 50mm x 50mm framing has diagonal cross bracing to create a very robust structure. The door, which has a rim lock, is fitted with zinc hinges and is braced as well. For such a large shed, double doors are probably a wise choice and these are available as an option.

The floor and roof are tongue and groove, interlocking shiplap cladding forms a tough exterior, and Georgian style windows complete the shed's handsome appearance.

When the item is delivered on a pallet, the pallet and packaging are non-returnable and the goods can only be manoeuvred on a flat and level surface (i.e. not a gravel driveway) by a pallet truck. On some occasions the driver will split the package to assist with manoeuvring of the item. Once you are happy, we will ask you to check the condition of the goods and sign for the delivery.
