In 1973, the subsidiary Hanno Austria was formed in Himberg, near Vienna. HANNO expanded constantly in the years thereafter. In the 1970s, four new production halls were constructed at the Laatzen site. The last new hall was built at the old site in 1991. HANNO (Schweiz) AG was formed as Swiss subsidiary in 2000, followed, in 2005, by a sales office in Moscow and, in 2010, the foundation of HANNO Vito Corp. in New York. Formerly a residential building, the old premises became too small and Hanno started planning the move to the new site in the industrial estate as early as in 1996. The project made progress with the completion of stages in 2001, 2007 and 2011.
The purchase of the adjoining administration building in mint condition by the end of 2013 marked the beginning of the “reunification“ of all departments. In a Herculean effort, the administration moved to the new site in only three days at the beginning of March, followed by the last production departments.
