I don't see any savings in materials used.A coop with exterior nest boxes allows for a smaller, more proportional & scaled to a chicken structure and results in less materials used & lower cost, whereas a coop with interior nests requires a larger, more costly structure. There's the matter of asthetics because city people want a cute little coop that blends in with the neighborhood, not something that looks like a shanty town outbuilding and sticks out like a sore thumb.
