I know the type of chicken coop you are thinking of. We used to have them years ago. Basically, it is elevated roosting areas with a roof over it and no floor. Sometimes they had walls, and sometimes not. We used fencing under the roosts to keep the predators from getting at the the birds at night. The poop just falls through to the ground below.
In this area, we don't have to deal with cold weather, shade is more of a concern.
The only thing I would do differently now, is put a layer of styrofoam insulation between the top of the coop and the tin roof.
I am in Phoenix, so the coop I have now is more or less a large tractor type. We built it low so that no one could see the chickens. They are behind eight foot walls, but you never know.
Build your coop out of sight, and do it on weekends. You don't want a visit from an officious building inspector.
