I bought this coop last week it took about 4 days to get it. Its made very well for the price. I don't think you could buy the materials and build it yourself for the price. I added a wire floor and coverd a few holes its has (in the roof area) to keep mice out. Its about chest high 2 feet wide to give you an idea of size.  I would recommend this coop to any beginner. I may just buy more as i get more birds and hook them together. I painted.mine to help with weather. I will be using mine for ducks. The egg box has no lock and the floor comes out so it would be easy for a predator to get in i screwed the floor down and put a lock on the nesting/egg box. Over all amazing buy
