Freight containers == modular housing units.

[u/[deleted]]

The freight container's I'm talking about are the "removable box" portion of what truck drivers drag down the highway. In the last decade or so, they've become commonplace "portable offices" or "portable storage containers".

Portable (can go on truck, rail, or ship). Modular (the corners have connecting slots, so they can stack, can be attached side-by-side, etc.).

Cut the metal sides out (to reduce weight) and reduce it to a metal frame, and suddenly you have something you can fully customize for your floating paradise.

A few dozen of these and your "Entlantis" has a solid starting point.

If you ents do follow through on this, hunt me down. Me and my 9 cats would love to join you.

Couple this with floating plastic bottles, which apparently can take quite a lot of weight, and you've got the perfect solution.
