Check out these preliminary layout plans!
A welcoming entryway and coat closet, an absolutely HUGE living room (we should probably rename it the party room), a formal dining room and, to top it all of a crazy/cool/huge/awesome/spectacular kitchen—that island is 12ft long!! 12 ft!!
2 big bedrooms, a master complete with an ensuite and a smaller living space
Cross section–gives you an idea of the ceiling heights and how the stairs will work.
