A former colleague at Boeing went to work for Eastern Airlines and moved to the grater Miami area in the early 1970s. I visited once during a Boeing trip and saw their house.
It was a three bedroom rambler in a major development and houses were still under construction in the neighborhood. I was amazed by the construction techniques. Vertical sections of rebar were planted about every 18" in the concrete foundations after they'd been poured. Walls were made of hollow concrete blocks threaded onto the rebar with concrete "gluing" them together.
Once the wall reached the required roof height, another concrete rectangle, similar to the foundation, was poured in forms around the top of the wall, also with horizontal rebar going all around it.
Outside doors all opened outwards so the wind couldn't blow them in. The development got hit pretty hard a few years later, but damage was minimal. I don't know if that type of design/construction was common in Florida.
