18ft x 12ft Heavy Duty Apex Garden Shed

Write the first review


Extremely spacious, the 18ft x 12ft Heavy Duty Apex Shed is designed and built to a very high standard, with enough floor area for both the storage of garden equipment and any DIY projects you may wish to undertake.  

Two inch framing has additional diagonal cross bracing that creates a very strong structure with a single zinc hinged and braced door fitted with a rim lock as standard. If wider access is required, why not upgrade to double doors?

You won't find any chipboard in the construction of this shed, only excellent quality Scandinavian FSC timber. The floor and roof are tongue and groove, and traditional coach bolting and galvanised nails are used instead of pins and staples.

The exterior is interlocking shiplap cladding that has been treated, Georgian windows add to the shed's attractive appearance and durable mineral roofing felt is fitted as standard.
