A functional, optically pleasing auditorium is to be found housed within the traditional buildings of the Welfengarten University in Hannover. The existing steel and concrete sub-construction received new covering and air conditioning vents were set into the stairwell. To fit the existing stair depth of only 820mm and the chosen fixed desktop, our spring-assisted tip-up mechanism was installed, allowing adequate walkway in spite of narrow stairs. Frames with corresponding stair angles are fixed to the front of the steps.
