My wife bought the plans for our larger replacement coop. They are very good plans and since I live in Portland I have seen the coop first hand. The instructions are very good and easy to follow. Unfortunatly I didn't exactly follow them I built something much larger though I did follow the plans to build the door, and the run portions. I had to attach the run a bit differently. Oh heck I just built a massive 8x8x9 foot cube with a roof on it. and two doors (one people and one chicken) and two windows and a 5 box nest box. and then added a very large 15x10 enclosed predator proofed run. (still in progress.)
But, the point is the plans are good and easy to follow. I just used them as a starting point.
Good luck with your coop building.
