In Holland, they have built houses on reclaimed 'land' that is just an

I thought there was a fully floating 'house' on the Thames that looked
like a house (rather than a houseboat) and could float up and down on
some pile / tracks.

I think they had to ballast the thing up to compensate for the
furniture (grand piano) but that might be a small inconvenience
opposed to bailing out the ground floor (or worse).
