Florida can experience many hurricanes throughout July-November in hurricane season causing many houses near the beaches and spots where the architecture can’t withstand the strength of the hurricanes causing many houses to break down, fall over, tear, get demolished, etc. In Jacksonville, there are many old houses that need to be reinforced to withstand harsh environments and to do that you would need to add a layer of framing to the house with stronger materials to make the house stronger making it able to survive.
