Interior Space and Exhibition Design Private Penthouse Residential by Fouad Naayem The furniture layout give the space an open, airy feeling. As one enters the apartment, they can not but notice the staircase that serves as the backbone of the apartment, connecting both horizontally and vertically, physically and visually, from the bottom all the way up to the rooftop and modern pool. While furniture, lighting and contemporary art contribute to the subtle refinement of the penthouse, the choice of noble materials has played an equally vital role. The penthouse has been designed to make the urban feel both at home and at the retreat.
