It sounds like you're doing great in pre-planning Too many of us get our birds, THEN decide to hurry up and build a coop! Then we often make it just big enough to handle the minimum, not thinking of how we might like to expand....sigh.
The roosts should be higher than the nest boxes to prevent the chickens from roosting (and dirtying!) in the boxes. My boxes are 18" off the ground so that they can walk around under the boxes. My roosts are above the droppings board which is 32" off the floor. First roost about 36", then the next one about 48". I have a ramp so that it makes it easier for my heavier Jersey Giant to go up and down w/less wear and tear on her joints.
The roost and boxes are on opposite sides of our 8x8 coop. The top pic shows a small "holding" area we made when integrating our younger chicks to ones that were 5 weeks older. We had to put a lid on the holding cell so that the older girls would not fly in with the younger ones!
Good luck!
