Tucked between layers of sliding cabinetry, the essentials cooking can  be found hidden at the core: stove, oven, faucet, sink with a  preparation surface in between and a refrigerator to one side. Why stop  at the kitchen? This same strategy could be applied to beds, televisions  and other household objects in various rooms just as easily.
 When not in use, the constituent elements can be slid up and down to  move them out of the way and create varying layouts and spatial  configurations. Of course, those of you with some construction  experience and keen eye for functionality in design will notice one  small problem: unlike in these idealized illustrations, it would be very  difficult to allow plumbing-or-piping-required fixtures to float freely  in space.
