Frankfurts newest, Northernmost urban quarter is connected to the Frankfurt subway system by the newly built train line 18 „Frankfurter Bogen“. The terminal stop lies directly on one end of the urban square „Gravensteiner Platz“. The architects had to work with a very narrow platform (only 4m) on which - due to the neccessary passage widths of 2m on either side - no furnishings were possible. Consequently the waiting area with seating possibilities and weather protection is located at the end of the platform under the wide area of the roof structure. Apart from purely functional features such as protection from wind and rain, waiting areas have to have a high sense of orientation, whilst being easy to maintain and keep clean, all the time being completely vandalproof. The main interest of the architects was to create a thin, quiet and consequently elegant structure whilst maintaining all the necessary budgetary needs, functionality and robustness. 12 stainless steel roof elements consisting of upside down pyramids lie on thin stainless steel columns. All the neccessary elements such as lighting and speaker fixtures are flushly integrated into the descretely folded roof structure, emphasising the appearance of the wing of an aircraft.
