I helped a friend put one up not to long ago that was just like that, it came with this really nice floor, windows and even a skylight, and went up in only about 3 hrs with just two guys. He paid alot more than your price listed for. Good luck.
I think it's plastic. I bet it would get hot in summer and cold in winter. Is there any way to insulate it? I would go for a wood building. (I'm assuming you meaan it to be a coop.)
That would make such a great henhouse/ccoop. I says it's made of resin material? Did I read that right? That doesn't sound like it has much "framework" involved to me.
