Well, having a space of your own is actually ideal. Living in a rented apartment can be all good at the start, just as long as you've got money to pay for it. But just as you said, you really can't pay rent forever, so being the boss of your own environment is the way out.
I don't think it will be boring, a home building process can never be boring lol, there's always something crazy and tangible to take home.
