There is nothing wrong with wood construction, not normal in UK apparently means crap to some people. Ever seen the barns people love to convert, often hundreds of years old and made of wood?
Wood is a strong, durable material, with proper maintainance there is really nothing to prevent a brick or wood house lasting well beyond anyones lifespace.
As with essentially every single thing in life, its in the quality of manufacture. You can build a brick or wood house that can last 200 years easily, and you can build a house made from either that will fall down in a year, and most of the rest fit inbetween there somewhere.
Anyway, Florida sucks, hot with huge humidity, no thanks. Probably a high crime area, hurricanes, old people, republicans
