The interior of the top apartment in the by studio PROTOTYPE designed Vertical Lofts has been designed. The apartment exists out of three laters, vertically con- nected by several voids and staircases. In contrary to the brutal concrete exterior of the building, the interior feels subtle and warm. The core of the building is coated with a special wooden pattern that forms a fine continuous line through the complete house. Different intimate spots are part of this core and give the user a comforting feeling within the interior.
