Autoban has created an interior shell at parapet level, which distinctively separates itself from the architectural contours of the building by a lighting channel, and becomes a stand-alone structure of its own. Its distance from the architectural shell of the building also makes room for hiding the lighting as well as other mechanical and technical systems, and therefore becomes a functional solution for the interior. The said interior shell is made of wood (material changes at the pool and fitness area, and becomes marble in two different shades) to contrast with the concrete structure, and add warmth to the space. It is designed at parapet level to create a rather enclosed space of human scale.
