Well, unless you're better than I, even a house you build will have "some small
thing than you don't like". We built (well we paid a whole mess of folks to
build it for us) our current place about 15 years ago, and extensively remodeled
it a couple of years ago. And there are still a few things we don't like.
Maybe on the next remodel...
