Are you outgrowing your apartment? Need an extra room? Well, just hang one outside your window (hope those cables are strong!). Here's a "walk-in sculpture" called the Rucksack House in München, Germany.
The cube is a light and empty space, free from connotations and open to its user's needs. While still being inside a private atmosphere, one has the impression of floating outside of the confines of the actual dwelling above the public space. Folddown furnishings and a multitude of built-in openings on the inside provide extra living space with direct daylight. Sections of the walls unfold, with the help of hidden magnets, into a desk, shelves, and a platform for reading or sleeping. The Rucksack box is suspended from steel cables that are anchored to the roof or to the facade of the existing building. The construction is a welded steel cage with a light birch veneered plywood interior cladding. The outside cladding is exterior grade plywood with an absorbent resin surface punctuated by plexiglas inserts.
