The main floor of the J-2018 plan is 1660 sq. ft. If you would like to see the total square footage of both floors at 1500-1600 sq. ft., that would be a problem.
If we were to add a floor over the upper part of the greatroom, we could get two bedrooms and a bath up there. We should not have to use dormers as we already have the large eyebrow to work with. But this would put your total square footage in at approx. 2350 sq. ft.
It might be best if you were to call me. 877.325-6617
