Go for it. If the concrete slab is already there, that is. Otherwise, check out the building codes for where you live, first.
But, as for looking down on the coop? Man, I'd love to be able to do that! My chicken run is very close to my bedroom window, but the coops - yes, plural: coops - are a tad bit further away. My chickens range freely on the property, so I hear crowing and clucking and lovely chicken sounds all over the place when they're out.
I have several roosters. Their crowing from inside a coop at night or really early in the morning isn't deafening.
And as someone else has said, if you get flies and mites and poop odor inside your house from a close exterior coop, you're doing something wrong. No, wait, flies happen. But the rest? Pshaw.
Do NOT be surprised, though, if some day a chicken is looking in your bedroom window from the outside sill. If that is a possibility that pleases you, forge onward! (I'd love it.)
