New Construction - Bonus Room Over 3 Car Garage
I'm in the early stages of considering building a new home. I've looked at a set of plans that include 2800 square feet plus a 900 square foot bonus room over a three car garage. Based on my discussions with contractors and other recent home builders, I believe I can build my house for approximately $110 per square foot. Is there a way to figure the cost per square foot of the bonus room? At this point I'm looking for a very rough estimation. It obviously won't cost the full $110, but I have no idea what to plan for? I would plan to heat and cool the area and would have electrical. Any ideas?
