I have a friend in Indiana who has plenty of cash, acreage in the city and designed or sketched his house he wanted built. One huge bedroom, equally huge living room and normal size everything else. The architect said he had never drawn up a one bedroom house, much less one with 2000 sq ft.
It's perfect for him, he is divorced with no intention of getting married again and he has air mattresses for his guests. He had a barn built to house his tractor collection along with every antique tool he can find. He's happy as a clam.
