Gazebo Preparation

You will need a firm and level base for the Gazebo to go on such as concrete or slabbed paving. The unit will require anchoring down to the ground (anchor bolts not included).

To ensure the longevity and structural integrity of your Gazebo, the posts need to be securely and safely anchored to the ground / your chosen base.

Please note that we do not include any anchors, footings or ground fixings with this product. Suitable anchoring techniques are listed below.


The Gazebo will arrive on a pallet delivered by our trusted courier. It will be delivered on an 18ton vehicle and a tail lift / pallet truck will unload the pallet. If there are any access problems for an 18ton vehicle (similar to the size of a bin wagon) then please advise us when placing the order so we are able to make alternative arrangements.
