Feels thin and maybe flimsy but havent completed putting together. If I can update I will. Lots of pieces and a lot of screws but excited. Almost finished looks like about and 9 hour job with three people. However, we did actually take about 45 minutes going thru each piece and making sure we had everything.  Labeled well. Gladly a Protective film on the panels to prevent packing and installing scratches. My husband hated the directions toward the end he said they were worthless. Special about the door and vented windows.
