  1. Like Jock said, it would really vary depending upon how you plan on using the space. If it’s an individual apartment, then it’s probably going to start at $200 a square foot or more. If it’s just living space and you don’t need all the plumbing and such associated with kitchens and baths, then it would be a bit lower. Hope that help a bit.

    The next step for you would be to call an architect and discuss the specifics of it.

  2. It would depend upon what you want to add to the new floor. An additional unit vs. just additional living space will impact the cost.
