The Institute for Aviation, designed by Curt Siegel and Rudolf Wonneberg, was built between 1962 and 1964 and was in need of comprehensive technical and energy-related upgrading. The brief was to preserve the character of this exemplary Stuttgart Late Modernist building and convey it into the present. The original facade was preserved through internal insulation. Glass partitions separate the corridors from the main hall for fire safety without compromising the building’s transparency. All new additions are integrated into the clear tectonics of the existing structure.

The institute consists of two perpendicular buildings: the institute building and the testing hall, connected by a bridge and an underground passage. The institute building is a reinforced concrete skeleton structure with an exposed aggregate concrete facade. It houses office spaces, seminar rooms, laboratories, a large and a small lecture hall, as well as a library.

The testing hall is characterized by its distinctive external steel structure and profilit facade. This is where the foremen’s offices, workshops and changing rooms are located. Fire protection renovation was carried out on ceilings, walls, columns, doors, and individual parts of the facade. A new escape staircase on the north side of the institute building allows for evacuation from the first and second floors. Furthermore, the technical building equipment was completely renewed.
