It's a regular home built to float on water. Often 2-story, roof terrace / balcony, the works. In the NL there are many examples. Designed to be anchored in quiet waters & sit there. In contrast with houseboats, which are often re-purposed old cargo ships. Which were originally designed to move often (and thus, deal with choppy waters & so on). In practice both types rarely move. But it happens occasionally. Over the course of last summer I've seen ~half a dozen crossing various lakes here. They're even for rent here (as a halfway between boat & vacation home). On land: it's been done... 'once or twice'.
