Addition Question

[guy]

Ok first timer, so here I go:
I have a 4 bedroom 2 1/2 bath house colonial about 20 years old.
I would like to add a family room on the existing side of my house.

My first thought is to add a 22' deep by 14' wide addition.

Now my questions:
I would like the first floor to have a 10 foot ceiling and the 2nd floor just be an unused attic with a height of 6' to match the roof line of the existing house. I don't need extra bed or baths but i really could use extra storage space and would like to have a higher ceiling in the family room since the rest of the house has 7' 8" ceilings. Does this sound ok? Or is this a bad idea?

About how much would this cost per sq foot, I mean would I be paying for 308sq ft or 616 sq ft. with the unfinished attic. A ballpark number would be a great help.

I understand I will need to talk to a builder/designer but I'm just trying to get some ideas.

Thanks

Also this side of my house has basement windows. If I do a craw space can I block my basement window. I used 22 ft deep since this will only block one window.

All depends on where you live. Prices can vary 15 to 20 percent just because of location, and then can vary greatly accoding to the quality level you want, the problems presented by the job, current market conditions, etc., so if I gave you a number, it could be way off in either direction. Your best course of action is to speak with good local builders who specialize in additions.

There is nothing wrong with your plan, though. Good luck.
