Was pretty easy to assembly. Took one person about 3 and a half hours to completely assemble with a second person only coming in to aide with holding pieces together until screws were in, particularly the roof. Only negative was the directions had pieces and screws labeled with letters but the hardware bags had numbers on them. There was a key at the beginning of the instruction manual but it was annoying to go back and forth. Also the pictures in the instructions were sometimes hard to decipher. Overall pretty nice shed.
