Bought this to add living space in our back yard. Packed & delivered in two well protected boxes. Manufactured and assembled very nicely. Take your time & read/prep in advance, and it went together nicely. Did with my wife over two days (between doing other chores). The key is to take your time. Had a drill for drilling in wood (soft wood so don’t go too fast). Multiple  ladders to move around (when doing roof). Prepped washers on the screws. Take your time and look closely at the pictures.
