>What do you think about floating houses?
Nice, affordable and in most locations pretty good.
Typically the foundation is either maintenance free pontoons or unsinkable (low/no maintenance) concrete barge.
Steel hulls need to be pulled up once every 5 years for new anodes, the other two... maybe once every 25 years you'd need some proper inspection.
I'll try to answer more in the other bread.
Largest cost is for docking, getting water and land power is more expensive than for a villa.
If you are on a smaller lake or river, esp sweet water, just go for it.
If you get it on the coast exposed to the winds and high waves.. consider another location.
If you are on pintoons, ensure enough ventilation (equivalent to crawl space) underneath. Personally I would prefer unsinkable concrete barge over one with a basement (simply due to not having to worry about any cracks).
