That could be a pretty nice cabin or hunting shack. If you have property out in the woods something like this would be a good start for an off grid location.
I'm guessing that the building codes in the larger Houston area will just get worse after this flooding. It will probably be like New Orleans after Katrina, a lot of people will never be able to return to the area. Interestingly enough, after Katrina, a lot of people relocated to the Houston area, now they'll be forced to relocate somewhere else. Climate refugees.
