The erection of exhibition buildings showed a very positive development in the eighties and a loyal clientele was gained in the field of entertainment electronics.
Meanwhile booths for brands such as ITT, Graetz, Schaub-Lorenz have been constructed for more than 20 years.
Some customers such as Nordmende, Sony and SEL-Stuttgart significantly enlarged the scope of their projects. As a result of the request of the SEL exhibition department for the CeBIT 1988 to construct an approximately 3000 m² new exhibition area, the task of the total building work was given to Holtmann as the general contractor.
