Think about doing deep litter at least in the coop. Saves so much time, effort and you get wonderful compost at the end of the season.
Protect against the predators prevalent in you area. A yard of woven wire or hardware cloth can save lives.
Think about your keeping style. I'm a lazy keeper, so they can go in and out the pop door without me opening it up in the am. I keep all my food stuff and water jugs at the feeding station outside, drop in feed, pour water, mix, let sit til next day. Feed. Actually, I make about 3 days at a time. There is always water inside the coop they can get to. Turn your bedding every so often, helps keep the bottom dry and chickies like to scratch at it for goodies.
If you don't have water near the coop, invest in a couple of the 5 gallon kerosene jugs to use. Nothing worse than being in the middle of the mornings chores and discover no water.
Make your water automatic. That way you can fill a big container and it lasts a couple of days.
If you go with dry feed, try to make it as tight a container as you can. Either they will bill out a lot of it, or just straight up spill it. This attracts vermin and raises your feed bill. Never leave food out overnight uncovered. It will attract vermin and predators like possum and coons.
Build a table of some sort. Nothing like carrying out a bottle of water with you while you watch chicken TV, setting it down, and go to pick it up but it's been knocked over and rolled in poo.
Think about your wind direction. You don't want any air moving directly over your birds. They can handle lots of cold, but if they are wet or damp, they will lose heat to the air. Vents on the north side, low down, are great for summer, it brings in cool air to flow up and carry the hot air out of the coop. Have a cross breeze for summer too. Make them coverable for winter time.
Good luck, take pics.
