Coop build!

[I am the Chicken Lord]

Building a coop for the flock. Deep enough for deep litter method, two large access doors, lots of ventilation, roost space enough for 30 birds (?), 5 nesting boxes, chicken-sized entrance will lead to the run, predator-proof underside will have PVC auto-feeders and two doors for easy access to change their water (can’t do auto until it warms up). Still a work in progress, but I’m proud of it so far. What are your thoughts? I really care about my chickens, so I want to do a good job. Any tips or advice would be helpful, This is the first time I’ve built a coop this size.

Here are some of my thoughts , as well as ideas on some revisions.
Your coop is 4 foot x 8 foot. At 4 square feet needed/suggested per chicken,,,,,,,,,,,,, that makes your coop able to handle in the general population of 8.
You can probably squeeze a couple more in, but overcrowding brings about more issues than desired. If you want to raise battery hens,,, 30 hens in your coop, the site will not be pretty.

Spoiler: Battery hens, unpleasant view

If you decide to keep under 8 hens, then I suggest making your roost across the back of coop, a single board, and having the area below, for hens to walk around on and scratch. Other option is to only keep 2 of your existing roost bars, and remove the other.
I would only do Deep litter method, if it was on the ground. I would keep wood shavings, or hay/straw on elevated coop floor. Throw soiled bedding into outdoor run, or compost pile.
Ask anything else you are not sure of. What kind of chickens are you desiring. (meat, or egg layers)

I agree that you cannot keep 30 hens in that coop.
However, if you build on a large, fully predator proof run, where you never have to close the pop door, that coop could serve 10 or 11 chickens. I had one that size with the setup I described and they did well with it. I didn't do well with it as it's a real pain to work in a coop you can't walk in.
Your roosting bar set up isn't going to work very well either. It will be difficult for the chickens to jump up between the tightly spaced bars. You'd be better off running a single 8' roost bar down the middle, centered along the 4' width.
How do they access the nest boxes? The nest box arrangement looks too low.
I would enclose the soffit area with 1/2" hardware cloth and cut out the top 8" or so of your gable peaks and install 1/2" HC there as well. Because you do not have overhangs on the rakes, you'll need a louver style gable vent to keep out rain and snow.
I would also cut about 1" off each side of the peak of the roof decking and install a ridge vent before putting on the roofing.
Are you planning on installing any top hinged windows for additional ventilation in the summer? It will be very dark in there without some windows. You can use old windows for this purpose and just cover the openings from the inside with more 1/2" hardware cloth.

roost space enough for 30 birds (?)

I would question that number of birds too.

Give us some dimensions, please.
Rule of thumb:
9-12" of roost length per bird, roosts 12" from walls and 18" apart.

Ditto Dobie's suggestion of a weather and predator proof run in your climate.

Thanks for adding your location.

I have to agree with the others, if that's 4x8(?) I cannot see any way of fitting 30 in there even if they strictly use it for roosting and laying. Roost bars appear very close together (where you'll get squabbling and possibly vent cannibalization) and ventilation would be insufficient for that many birds. Also not possible to do deep litter in that particular set up.
