In the Braunschweig airport district, directly at the Lilienthalplatz, the “Lilienthalhaus I” was finished in 2017 after a construction period of only 16 months. The central visitor and service centre for aerospace and mobility is excellently located between the A2 motorway and Braunschweig airport. On four storeys, the futuristic-looking building accommodates flexible office spaces, a divisible event room and a team bistro on an surface of approx. 5,000 m². The sky lounge offers an impressive view over the entire research airport.
The eye-catcher in the publicly accessible atrium is the self-supporting spiral staircase that stylishly connects the four levels of the building. It is the elliptical shape of this expressive staircase with folded steps that catches the visitor’s attention. The floor plan was particularly challenging for the production process. In order to achieve an even radius, the entire realisation of the steel construction had to be very precise. However, the MetallArt experts managed the job excellently. A tread step cover made of Jura limestone completes the modern design of the spiral staircase and blends harmoniously into the ambience of the bright atrium.
