The window is just a plastic cookie sheet that slides up & down.  The right door doesn't line-up correctly to lock but I'll figure that out.  We've had two storms since assembled & it still stands plus there's no water inside!  I would definitely order this again. It 's worth the price. The assembly is lengthy but I paid three young men & it took them 5 hrs.  It does have a floor.  The skylights make it easier to see inside during daylight. The little shelves are useful too. I love it!!
