Fairly easy to put together. It's advertised as 4' wide by 2' deep, these being the outside dimensions, (which is actually the size of the roof). The height is given as 6'. The actual usable inside dimensions are approx 1' 5" deep by 3' 6" wide by 4' 7" high. The photo shows that a builders bag of logs, (a 900mm cube), with lengths varying between  9" to 11" has effectively filled it. (No room for kindling on the shelf).  With 8" logs it could be double stacked. Sturdy and should last a good few years.
