Extension experimenta Heilbronn

Heilbronn, Germany, 2019

The five storeys of the geometrically challenging building have similar, pentagonal floor layouts and are stacked like boxes offset to one another. They each consist of an exhibition area, or “theme world”, and a circulation area serving as a link between storeys as part of a spatial spiral of rooms connecting all floors.
Covered by a cupola, the two-storey "Science Dome" with a movable auditorium is hidden underground.
Truss girders along the atrium and composite steel girders create trussed tubes that connect to a reinforced concrete core on every floor. Thus forming a solid construction, the interiors can be designed without any supports. The suspended spiral construction and large glass panes provide a maximum of transparency and panoramic view. Triangular-shaped facade elements form the external skin of the themed worlds.
The extension building for the "world of learning and experience" has already become an architectural landmark in Heilbronn.
