Materials provide the decoration. A room designed for a company's c-suite embodies monotonous but chic atmosphere by material combination with shades of grey and brown: furniture and closet doors in noce canaletto; furred out walls covered with grey stone slabs; a meeting table in grey marble and dark brown chairs. A customized built-in closet with handleless doors (w/ pivot sliding hardwares) equips a dry bar and a wardrobe.
