The main office of the Chamber of Commerce and Industry for Munich and Upper Bavaria is an important urban reference point. It consists of two listed buildings surrounding a covered inner courtyard. Over the years, both buildings have been subject to multiple alterations and adapted to meet the requirements at the time. In addition to strengthening the fabric of the building, the aim of the renovation was to restore the prestigious look of the listed ensemble. The architects’ design involved a reorganisation of the functional areas. As a result, two busy public areas were created that were intended to be as transparent as possible, as well as a compact core, which combines the main offices and vertical access through the building. The ground floor is where the public areas, such as the consultation zones and the Börsencafé, are located. The functions are separated via steel/glass partition walls with doors of the same material. The atrium on the ground floor and the exclusive rooms on the first and second floors serve as conference spaces. The rest of the space on the upper floors is used as office and meeting areas. The old façades were carefully restored. The existing window and door units that were retained were updated and supplemented in places; all the other opening units were constructed to replicate the original style.
