Cost to add top floor addition on brownstone

Categories: Configuration

Can anyone give rough cost to add a top floor addition to a small (3-story) brownstone, which is NOT on a landmarked block. I know there are lots of variables, but if you’re just trying to add something that is say 450-550 sf (say a master bedroom with bath), is there a ballpark? 100K? More? How big a deal is it to break through and then have to add a new roof/skylights?
