COOL PENTHOUSE A prestigious modern penthouse terrace for Diane Benussi Diane wanted a sophisticated, contemporary, yet fun terrace for her new penthouse apartment in the city. A scheme that would link the stylish interior with the exterior, but not detract from the fantastic city views. Based on spheres, reflective surfaces were used to make the most of the space together with glass and stainless steel. Smart topiary reflects the theme and glass lights were used to create a party zone at night.
