Here is another question for someone... I am looking to build a home, a bit out of the norm though, really like the precast concrete look and love the speed it goes up with... I have pricing on the enclosed package, a wide open concrete interior ready for me to do interior finish etc. I don't really want to harass contractors though on stick frame since I am not going that route..... but looking for comparisons. So here is the question -- if I say a finished house is $350 a sq ft -- how would you split finished exterior to interior finishing?? Is exterior half?? More? Less? I realize this is loaded with variables, but high level comparison would be great.
