That looks like a good start on the coop, however I agree with some of the others. If I was going to buy a coop, I would look for:
Ventilation - a must, to help dissipate ammonia and odors
Windows - for light
Hardware cloth instead of poultry wire - for predator protection
Just a suggestion - For moveability, rather than a rope to pull it around, it might be better to put handle bar type things on it - one on each side. They could be wood, placed at about the height of the support boards you have there now. Not too high or too low for most people.
