Hi! Welcome to BYC!
Edited to add - I highly recommend this article.

There are others you can search here on BYC.
I've now used a variety of chicken tractors & our coops have become "offshoots" of them. I LOVE open air hoop coops made from CP. I used tarps as roofs, some have actually been not so nice looking, but they have worked. I have also hooped pens that were here on our property as well as one 10x10 chain link dog kennel (for the dogs, not chickens).
CP hoop coops can be made some what light weight or can be really heavy or even be stationary. They can have walls of wood, tarp, tin or garden panels - back & front. The hooped portion can have a variety of roof styles - tarp, tin/metal & different garden panels. They can be covered completely from front to back & all the way to the ground on the sides or any variation that you like. You could even do a completely enclosed coop, above ground, w/I the hoop.
There are many other styles of hooped coops in the BYC article section under Coops. There are also other styles that would work here in NC.
The main thing would be to decide what you are looking for in a coop. I know lots of folks that LOVE having a coop w/ a floor & foundation & having poop boards. I do not. Even if I did a shed, I'd want it pole barn style w/ the floor being the ground. No poop boards.
I still regularly go through Google images & Pinterest, as well as BYC. I read & evaluate different ideas to see if they'd be improvements to what I have. Some look like they may be & I'm looking to incorporate some new things this year while updating some coops we have. Some are easier (dog kennel panels w/ gates - both welded & chain link for the fronts of my permanent hoop coops. No wood), but I can already tell you the gates are too narrow - wheel barrel won't go in. Mabe ok on the 4x8 or 8x8 size, but not the 10x16... So, will need to build or purchase a gate/doors for the rear wall that will allow a wheel barrel (gorilla cart) access.
If your coop is close enough to or will have power run out to it, you can run fans or set up a mister. A sprinkler can also be set to "water the roof". This will help in the heat & oppressiveness.
Deciding what you want & how to build it, is part of the fun.
Nothing fancy. Some of what I've done using mostly what was on hand & yes, the 1st 3 hoop coops were made w/ chicken wire. We learned that was not a good idea as on current property we have ground predators that can rip right through it. I also like to recycle & upcycle. Some of our CP panels traveled from MT to NC in 1997 -

Chicken tractors. The four a-frame CP ones (5x8') are wired w/ 2x4" wire. Updating w/ 1/2" HWC. The treated wood bases were built in 2019 & all have rotted out.
