My wife and I built our own home, the best advice I can give you is location, location, location. We couldn't find a plot in the area we wanted, but found a great plot 1/2hr away from where we lived. We thought just half an hour wasn't a big deal, but it turned out that we ended up feeling isolated from everyone and everything we knew, and missing out on things we wouldn't otherwise. Yes, we were sitting in a great house in a great plot but wanting it to be back in a location we were familiar with and could nip out and easily see the people we wanted to and do the things we wanted. The extra distance from work also became a slog when we weren't enjoying where we were. We sold our 'forever home' and moved back to where we wanted to be for the location alone.
