On any outside wall of any home you can add a window. On a patio Villa unless your a corner lot, you will looking out at the wall of another patio Villa. The cost of adding a window is very dependent on what's in the wall. Is there plumbing or sink vent pipes that need to be moved. Wires for outlets that need relocation. Other things run through the wall there that need to be moved. Because there is no basement, most cable, phone, electric, doorbell, gas lines and any other flexible wires and pipes are run through the walls. And any that are run through that location would need to be moved. That can get expensive. So yes it can be done, but unless your opening up a nice view, consider the solar tubes as they really work well.
