In strict axial symmetry, the new exhibition grounds continue Karlsruhe’s and its palace complex’s tradition of being a “green city “, integrating buildings and landscape: A green axis extends across the entire exhibition grounds, starting at the landscaped lake in front of the exhibition ground’s main entrance past a garden courtyard in its middle and ending in the open countryside. Omnipresent views make orientation within the buildings simple and integrate the landscape, complete with a view of the Black Forest foothills, into all areas.
An overhanging, seemingly weightless roof, accentuates the main entrance, under which is located the four-story high exhibition loggia, which is separated by a glazed light interstice from the roof with its 26-meter projection. Special areas, such as conference and press centres, occupy the second floor and a restaurant the third floor of the wood faced structure. These are reached via galleries from the glazed-sided events hall, which provide views of the adjacent exhibition halls and the surrounding countryside. Irrespective of spatial and functional divisions, the conference rooms thus enjoy a direct visual connection to the exhibition halls.
Around the entire garden courtyard is a glazed gallery that connects the events hall to the four symmetrical exhibition halls situated on either side of the gallery. All the halls, each measuring 80 meters wide, are covered by curved wood constructions, which, because of bodice–shaped light interstices arranged diagonally, possess a certain rhythm. The structural cross stays are consciously “brought to light“ underneath the glazed interstices. Three of the four 160 meter long halls have smooth soffits, in contrast to the multifunctional hall that is characterized by a load-bearing rhombic-shaped wood construction with continuous overlaying girders. The roofs’ exteriors are faced in metal, as are all hall facades, as well as the roof wing above the entrance building.
