An architectectural firm in Madrid designed this modern, efficient space from a small apartment. One half is a fixed living area (seen on the slideshow) and the other half is divided into rooms using movable walls. The kitchen units and bathroom are on either side, and 3 plywood units can be moved to create kitchen, bedroom and sitting/utility area. The room collapses when the units are moved to another configuration. The walls themselves double up as storage and closet.
Technology is such that nowadays, movable walls and doors made from heavy materials can be moved with one hand. The walls are suspended from the ceiling and move along using tracks similar to what is used in libraries and archives. The bathroom looks quite small and narrow and it can get to be a pain to raise/lower the bed everyday. These are the only negatives I can see, everything else looks super. Of course, this is pretty much only suitable for people who live minimalistically and tidy up as they go about their day.
The name of the firm is PKMN pronounced pac-man, it shows they have a sense of humour. The video is fun too:
