I'm no master with regards to home design, but there are several nice designs which have been around a while that seem to be pretty good. If they didn't or weren't sound, i then don't think they'd be utilized that much nowadays. One kind of home design which has been going strong for a couple hundred years is the pier and beam design. - Austin foundation repair
It may sound like the name is too straightforward and that it would have been a lot more complicated of the design than the name suggest, however i can assure you, that's not the case. The whole thing is really made of piers and beams. A pier is dug underneath the ground to rest on stone after which piers are placed on top of that to produce up the home by connecting along with other piers. Pretty simple in terms of laying a home out, in my opinion.
This was a very popular home design before the 1960's. It is still used today, but other types have grown in popularity over time. However, the 1800's charm of your "floating house" still appeals to a lot of people, hence its still prevalent usage today. I've found the design kind of charming, myself. - Austin foundation repair
