Forest 8 x 12 ft Overlap Shed

EAN: 5013053177983

(5) Based on 1 Review


This is a marvellous structure, that is full of opportunities, as the Overlap 8ft x 12ft Shed can have many uses including storage, as a hobby room, perhaps a workshop.

The largest shed in this range has six windows glazed with unbreakable polycarbonate that won't become brittle or turn yellow, the interior will certainly be bathed in light. There's a high ridge and eaves, so moving about inside will not present any difficulties.

Lockable double doors of course offer excellent access, whether you are carrying small or bulky items. They are reinforced with 'Z' bracing and the hinges hidden for extra security.

Square cut FSC softwood makes up the cladding, it is in the attractive overlap style and pressure treated. With a fine appearance, the cladding is also weather resistant with a fifteen year guarantee. There's no need for any preservative and, considering the size of this shed, will save a lot of time and money.

A black sand felt covered roof keeps the shed dry, particularly important if there are electrical items inside. Any heavy goods will be supported on a robust pressure treated board floor.

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 the manoeuvring of the item. Once you are happy, we will ask you to check the condition of the goods and sign for the delivery. Assistance with unloading may be required.

The windows on this shed look blanked out. Are they windows or could you put windows in and at what cost?

Dear Tracey Thank you for your question. This product comes with 6 windows as standard for the price shown and the side panels are interchangeable so they can go on either side.
