Interested you guys brought up crawl spaces. The last house I built I borrowed part of the plans. I spent a bunch of time trying to find plans I liked. It was going to be a capital gains home, so it really wasn't going to be a long term home for me. Ever house I worked on I would wander through trying to find something I thought would work. Yes I'm picky that way. One of the houses they had me hold off on some work. The contractor called me telling me he was ready and we setup a time. When I got there he wanted me to walk through with him even though I'd already been through. The basement was half full and the other half crawl space???
Anyway talking with him while we were walking through something clicked and I started modifying in my head the issue I had with it. He offered to give me a set of the plans which I gladly accepted. Had a draftsman make the mods I wanted and started construction. Later I had the same contractor come through. He didn't think it was the same house at first, even from the road it had a different look. It was fun to see his reaction to the changes. Yes I went to full basement. I've never had a crawl space home but have been in enough to know it's not for me.
The most unbelievable part was when I put it up for sale. The husband was the driving force!!! The wife was very quiet and he handled everything. The garage was oversized (30x40) with a wash tub sink (bathroom just inside the entrance to the home) and plenty of 220v and 110v outlets inside and outside the garage, and it's own power panel with room for upgrades. The basement was set up for an apartment with it's own entrance. They turned it into a short term rental. He makes great use of the garage space modifying his vehicles. First time I've ever seen the guy in charge of home buying!!!
