It's a great design...but the one in the photo appears much more sturdy than what I received.  Also, the pictures on the website show that both the top of the house and the top of the pen are hinged and open....and have nice supports to hold them open.  The one I received did not have hinged tops.  I put hinges on the roof of the house so I could open it.   It works with a 2x2 to hold it open....but the roof itself was warped a little, so the whole thing is a little kiddywumpus. 
 The whole unit went together easily, but it isn't rigid enough to be able to move it around.  I plan on doing some reinforcing to make it more stable and it should suit my purposes.  I bought it to have a way to introduce new hens to my flock and give them a safe place.  Would I buy it again....probably not.
