Shipping containers are designed for freight, not people, and it can be a challenge, trying to squeeze a house into them. The designers at Costa Rica's Cúbica have built some interesting shipping container houses, including this clever unit.
They keep the sun off the container (and maximise the interior space) by cladding it in metal siding, with an air space behind. Similarly the roof deck keeps the sun from hitting the container directly. A bump-out extension is added at one end to provide space for two bunks, as well as add a little visual variety. The sun shade folds down to seal up the unit for security.
Inside, the Murphy bed is hidden behind the fold-down dining room table.
Here's a view with the bed folded down.
I usually complain that shipping containers are too narrow and tight to make decent living spaces, but Cúbica have done a really good job of squeezing everything in here, including a full laundry, a workable kitchen and a bright bathroom, thanks to that shower with an exterior door.
