Came flat packed in polythene. Some water ingress during storage at their end so 1-2 planks were very damp (but clearly will dry out ok). Assembled easily in 40 minutes. Solid enough for the intended purpose for sure. I have creosoted the exterior although I suspect the timber is pressure treated. It could do with a polythene drop down flappy door thingy, but that will be easy to construct I feel confident of that. All in all pleased for the price
