You mean like one of those big casino boats?

It makes it easier to figure out where to park
the house, it keeps the house from sinking
wandering around during normal weather, it keeps the
wooden bits away from the wood-eating dirt, and it
gives you a fixed point to which you can
anchor your utilities.
Possible, but I'd think it would be easier, cheaper,
and less of a shock to the local code inspector if
you build a concrete cellar... no this is N'Orleans,
so there is no cellar.. I'm still voting for
a concrete perimeter foundation, 12" above grade,
with a 24" sealed "barge" platform as the ground floor.
that gives you a displacement of 2cuft per square-foot
or area, which means a total building+occupancy
weight of around 120psf.. so you're limited to
heavy 1-story buildings, or light 2-story ones.
When you outgrow the house, though, you can jack the
whole thing up 10', and build a (floodable) ground
floor underneath, on the existing footings.
What you do is build a elivated structure with parking underneath. then
you run pre-cast beam between a poured concrete wall. the home is then
concrete walls in a tilt up fashon. no woood other than the cabinet's ,
doors and trim would be wood. you'll have to build over the water level
of the flood. the parking level under the structure is the only way
you'll get pass the codes, since it is uninhabitable space.
