Thank you for your kind words about my build.I'm a huge fan of this article as it pertains to coop building:

@Yakisugi Coop did a great job of doing research prior to building. Much of that research is linked in the article. And, while you may come to different conclusions, the article does a good job getting you 'thinking the right way.'
If you read through @fuzzi 's chicken journal, you'll see a great example of how the community can help and guide you as you go. This ended up with a very nice hoop coop.

Have you considered an Open Air coop? @3KillerBs has good info on those.
To really know what you want from a coop, you'll also need to know what you want from your chickens. Are you in this just for eggs? Are you looking to harvest meat? Will you cull chickens after 2 years when their production slows down? Will you raise baby chicks? Do you want a broody hen to raise chicks for you? Do you have any interest in breeding chickens for show? Many people just want the chickens as pets. Some people on here don't care about eggs and the chicken manure for compost is their primary motivation. Those answers can impact decisions you make in how you construct your coop.
Oh, before all else, check your local laws and ordinances.
