First Coop build. You Tell me please.

[MaybeTomorrow]

Im part way into this and wanted some opinions before i made it too far. Coop is 3' x 5' and 29" off the ground. Roost will be up at the higher end with nesting box(s) food water at the other. Coop will be insulated and have one window which can be opened for ventilation and opening protected by wire. Im planning a full length (wide length 5' side) fold down door basically half the wall ill fold down for egg and cleaning access. The house will be insulated, boxes water and food elevated a few inches off the floor and the floor will have a cut to fit ridgid 1/4 thick sheet of black plastic similar to ridgid mudflap material that will slide out for easy cleanup. The run will actually be 8' x 10' and 7' high bascially five wire panels with wood frame which will be somewhat flimsy until tied together at the corners and the top set on it will be ridgid and have a tarp strapped over the top to keep the weather away from the actual coop hopefully extending its own life. One of the panels yes will have a door.I realize there are a hundred thousand different ways to do everything woth these coops but i need some good advice please. I have all the skills and tools needed so dont mind doing extra work to make things right.

1. I need constructive criticism on the plan i have explained if you can envision it.
2. I need advice on the best placement and size or strle of entry door
3. What do i want for heat for these 3 birds is on3 heat buld sufficient and where does it go?
4. Will they need a ramp to reack the roost if its 3 feet up and we clip their wings?

Heres a picture what i have so far.

I see i had a bunch of typos hopefully you (if anyone) can comprehend Anyhow heres a couple pictures what i have so far. Im going to use foil backed 1.5" thick insulation panels which can be removed easily if needed. Also the higher end of the cool is 46" and the lower 43" the roof will have simple asphalt shingle but will have a run with tarp over it. Im building the run in lightweight panels to make for easy breakdown when I decide to move.

The tarp over the run, how much snow is it going to hold before it collapses? You might want to use something sturdier than tarp.
The door should be placed where the run will be attached and be whatever style is easiest for you to operate. You could even make a hole in the floor and have a ladder sloping down under the coop to the ground.
You need more than just 1 window that can be opened for ventilation. You need something for cross ventilation. Air comes in one side and goes out the other. Even if it is just some holes drills at the top of the opposing wall and covered with wire.
You may not need any supplemental heat. 3x5 is pretty small and they will generate some heat by themselves in the coop when they sleep.
If you have room for it, put in a little chicken ladder for them to get up to the roost. Depending on what breed you have, they may or may not be able to jump 3' up to get to it.
Look for cold weather coops in the search area above to get some better ideas on what you may need.
