The shed has ledged braced doors featuring a button lock.

The shed is constructed with high quality pressure treated tongue and groove shiplap cladding, giving a smoother finish and making it more weather resistant.
The high quality floor joists give the shed a solid and sturdy feel.
The floor and roof are constructed from 12mm tongue and groove shiplap cladding.

The drivers are not insured to go into your property.

To do this you must leave a signed note detailing your instructions in a clear location for the driver to see. It is important that you sign the instructions as this will be taken by the courier as proof of delivery.

Please note we will always contact you by phone or by email to confirm a delivery date – we will not just turn up unannounced – if you do not have a confirmed delivery date please email us or call us.

we are delighted with the shed we ordered.. it arrived on time and was assembled with swiftly by a driver who was both pleasant and efficient. my only criticism would be the supply of only black roofing felt...it would have nice to have had green but that option wasn't available. I would recommend this supplier...very easy to deal with
