Brett,
My best advice is to leave your checkbook with the builder and get a plane ticket to somewhere else (Brazil?) for 3 or 4 months. /forums/images/graemlins/tongue.gif /forums/images/graemlins/crazy.gif /forums/images/graemlins/shocked.gif
One suggestion would be to look at the design of the bathrooms very closely. Is it exactly what you are looking for/need? Will it still be workable for you in 10, 20, 30 years?
Second suggestion is to spend the extra few dollars per door and get wide doors. This makes moving furniture easier, and helps with handicap access. My parent's house (1960s ranch) has extremely narrow doors (put in before they bought the house). A remodel was done in the basement many years back, and there is a washer, dryer, stove, and fridge that will not come out of the house without demolition. /forums/images/graemlins/shocked.gif
Are you hiring a builder to do the work, or doing it yourself? Check the prior work on any builder to make sure it is up to your standards. I've seen some very shoddy new work in some expensive homes.
How long will you live in this house? Plan to stay forever, or sell in five years? If moving again is in the cards, remember that additions/subtractions could affect the resale value. The previous owners of our current house enclosed the front porch and removed the front door. /forums/images/graemlins/frown.gif
We sold our house we built about 7 years ago, and have remodeled 2 houses since then. I dont know which is more work.
