I was disappointed by the interior size, only 8' x 5'. Removing the protective film was a real exercise in patience. All the plastic washers were still connected to each other so I had separate them one by one. Very thin gauge material, very sharp edges on some pieces. Very easy to strip the screw holes. The instructions (if you want to call them that) showed some screws with no washers required and there really should be washers on them. I had to run to the Hardware store and buy some. Some of the pictures of a few of the assemblies left me hanging. Looks nice though. It took me about 15 hours to complete and I am a retired sheet metal fabricator.
