In front of the two entrances, metal portals give the building a perceptible address in the street. They are covered with light-coloured wooden slats on the inner surfaces. The same wood is also used as wall cladding in the lobbies and this creates a seamless transition from from outside to inside. The use inside creates a bright and modern ambience in the common areas, too. Wood and warm colours are also the guiding elements of the design concept in the newly developed rental areas. A new lighting concept, efficient cooling sails and natural ventilation of the office spaces are further highlights of the revitalisation. 

The previously unused green areas in front of the building will be redesigned as an attractive outdoor space with activity and recreation areas and seating. The inner courtyard is enlarged by the removal of the surrounding glass roofs and becomes an additional, green lounge area. On the rooftops, two roof terraces offer a magnificent view of the Frankfurt skyline.
