If the kitchen island – made from a huge, illuminated piece of smoky quartz – wasn't enough, this kitchen in a stunning $57.5 million penthouse (£45m) comes with two exquisite decorative pieces thrown in. There's the rare, grey hutch (left of picture) by the extremely sought after mid-century designer Paul Evans and a stunning modern crystal chandelier by Magna of London. Bespoke aluminium cabinetry and glass countertops keep the look sleek and modern. Best of all, when you're entertaining you can close off the kitchen with the touch of a button as an electronic wall will move into place. Though with a kitchen this desirable, why would you want to hide it?
