More children in the same amount of space can be a recipe for temper tantrums, hence the need to think of rooms vertically when accommodating new mouths to feed (and heads to put to sleep).

These sliding, folding and fixed loft bedroom ideas from IMA Mobili are interesting products in themselves, but the layouts photographed also provide good inspiration for do-it-yourself interior design options.

Some solutions simply build to the ceiling with a combination of beds and storage spaces, while others deploy strategically at night, taking up floor space after it is used for other purposes during the day.

One of the unusual aspects of these mostly-asymmetrical systems is how they carve out unique corners, cubbies and otherwise-differentiated areas of occupation, giving each child the sense of having their own distinct portion of the shared area.
