Compact, not easy but not hard to do.  2 person- 3 hour.  Instruction so so.  The screw, nut and bolt just mixed in a big bag which is not cool at all!!!   Dent, bent, some scratches but do not want to wait for I use it anyway.  Other than the negatives above, this storage is very good.  fit if the  5' clearance side of the house perfectly.  

Pros: Great product / design 
Cons: packaging / shipping VERY BAD .  No corner protection - packing was not very tight. Things shifting around. Too heavy, corner of the box got damaged
