Text in English and German. Despite their usually very large volumes, works by Eckhard Gerber's Dortmund practice are structurally light and transparent, precise in their detail, and make an unmistakable impact on the urban space. Presenting the new exhibition centre in Karlsruhe, this Opus volume is devoted to a building complex with all the self-confidence of a city-within-a-city. Admittedly visitors are not aware of that until they have passed a breath-taking exhibition loggia whose daring roof, protruding powerfully along the whole length of the building, attracts attention even from a distance. The basic concept, tailored to the urban landscape, the functional ground-plan arrangement, the unusually subtle use of structures and materials for a large building of this kind, and not least the high design quality of all structural parts will certainly mean a high level of acceptance and a long future for the Neue Messe in Karlsruhe.
