Definitely a two person assembly project.  Over all pretty easy to build, some of the drawings are very clear, but if you put something in backwards, it is self critiquing and easy to fix.  The shape doesn't give quite the square footage you would expect, and the angled walls make using other shelfs or building any a bit more challenging.  Looks good, just with the 8x8 would have fit on my 8x8 pad.
