The existing building from the late 1980s was dated, had a compelling structure and a closed character. Parts have been demolished, while the remaining parts have undergone a large-scale transformation and have been combined with new construction. In addition to a large area of office functions for various government departments with very diverse and stringent security requirements, the program includes a comprehensive, flexibly usable and subdivisable conference and meeting centre for government agencies.
