I notice the house to the left seems to be built on pilings. And front door to house one right seems like second floor.
And the livable dwelling of the house the wing cars were in is elevated too
The codes in the Florida hurricane flood zones now require the living space to be elevated. I think it is 12 or 14 ft now. The space underneath can be enclosed, but the walls have to be designed to wash out so that the force of the moving water doesn't knock the structure over. Also you can't put your electric service panel in the lower area and you can't have any openings into the sanitary sewer. So the ground level is supposed to be considered a disposable, temporary space for garage or recreation room or something that could disappear in a hurricane.
