Have you seen this coop? It's not mine, but I'm a BIG fan of how gorgeous this coop is. I'd probably make the run a bit bigger, but otherwise, it's adorable. There is a blog that talks about it and has lots of inside pictures of it as well. Then if you scroll to the bottom, they have a very in depth construction set of plans for sale that lists lumber, cuts, etc. Should be pretty easy.
Here is the blog:

Lots more photos and the upside, it has storage built in for feed, etc. I'd show you MY coop... but from your responses of the others, I think mine will be way too large! But I do have a picture of a mini coop I'm building for my brother-- it's not finished yet, but it gives you the general idea. He lives in town and needs a small coop for 5 hens.
***I bought the window for $5 at Habitat's ReStore. Definitely check that place out for windows! Super cheap and you can find cute ones. Keep checking back if you don't find what you want, as they get in new stuff constantly.
I also built this little one--- (i need to get a current picture of it, because it's finished now) for a trio of silkies I have:
And if you have a deck on stilts, then this is an idea.... I built this too! (I'm a building fool around here) Anyway, I have a raised deck that is 6 feet tall, and I don't have to bend under there. I put a grow out pen for my chicks under the deck. This is it:
ETA (edited to add) I figured I'd go ahead and put on the picture of my large coop. You never know, it might spark an idea for you on a smaller scale.
