Have you seen her home designs? (Link, below) They’re very nice & practical. I have way more house than I need, but I wanted the LAND, and not the house. We, too, are only 2 people (and two dogs and two cats) in a 3-story house, that used to house five and sometimes six of us. We’re mid-40’s now, and our “farmette” it’s a little Midwest Goldmine, so we’ll hold on for another decade, then greatly downsize. ;) (I can’t wait, actually!)
I've heard stories of woe from people who had a custom house built. I've never met someone that went that route twice. Even people in the house building industry have little desire to build their own custom house. Apparently it's a big headache.
