The inner core rotates 180 degrees and is equipped with all the conveniences of a conventional kitchen, including a stainless steel sink with chrome single lever mixer, a waste bin and drawers. The upper circular shelf rotates through 360 degrees to house crockery, glasses, etc. Inside it has its own lighting, electrical sockets, electronics, water and waste disposal. By utilising the volume of the circular kitchen fully, it has been possible to offer a storage capacity equivalent to that of a large conventional kitchen. “It contains the equivalent of 12 cupboards from a conventional kitchen”, says designer Alfred Averbeck.  Link
