I have a room at the front of my coop that I use for storage, a built-in brooder a.k.a Maternity Ward and the nest boxes.
I have since installed 4 divider panels in this box to make five nest areas. As many as 28 hens have used these 5 boxes with no issue.
I like the curtains. I don't think the hens care. The rooster sure doesn't!

If you will be building exterior access boxes, I would make a solid, immobile pitched roof with about a 3-4" over hang and a panel that drops down in back like you see above. Having a roof that raises up leaves a pivot point along the wall where water can penetrate into the coop and get the nests wet.
I like this building design for bump out nests.
To keep my eggs from freezing in the winter, I use
seedling heating mats. I laid three along the bottom of the above box and anchored them with thin strips of wood screwed to the bottom of the nest box, not through the mat. I plug them into a switch controlled receptacle and turn them on when I need them to be on. They could also be controlled with a thermo-cube but that would leave them on all night when no one is in there laying.
The mats are vinyl so can be easily cleaned if they become soiled.
I used to put chopped straw in the nest boxes but have found that a flake of baled wheat straw works wonderfully and it keeps the eggs much cleaner. As the straw breaks down, the chaff will stick to the bloom when it's drying. It's annoying to have to get all that off the eggs.
