New office and administration building – Stuttgart region Chamber of Commerce

A vineyard in the heart of the city

The Kriegsberger Trollinger wine served at events hosted by the Stuttgart Chamber of Commerce and Industry is more local than most people imagine: The Chamber has its own vineyard and serves its own wine – surely a first in Germany.

In 1938, the Chamber acquired a plot of land on Jägerstrasse from Swabian nobleman Karl Moser von Filseck for the purpose of building new offices. The plot of land included a vineyard and small vineyard cottage. Due to the outbreak of World War II in 1939 and the dissolution of the Chamber of Commerce, the new offices were only finally constructed in the 1950s. Yet, the cottage and vineyard continue to shape the Stuttgart skyline.

This was also clear to Tobias Wulf and Kai Bierich of Wulf Architekten: “This vineyard in the middle of the state capital is truly special…”. Accordingly, the building is oriented towards the steep slope of the vineyard, which was expanded from 7,000 to around 9,000 square metres. The staging of the building and vineyard created one of the design’s essential features: an unobstructed view of the vineyard cottage from the city streets. The building itself opens to the vineyard and is divided into six levels. Visitors arrive through the main doors to the entrance area where the service desk is located. Some 100,000 customers visit the headquarters every year. With 17,900 square metres of gross floor area, the building provides a usable floor space of 12,000 square metres. Public areas are located on levels 0 to 2, with conference rooms and a cafeteria on levels 1 and 2. Levels 3 to 5 encompass the offices for the Chamber’s staff of around 270 people. The roof appears weightless and seems to float above it all, yet it is strong enough to support a photovoltaic system installed over approximately 400 square metres. Floors and ceilings of exposed concrete elements and walls covered with slabs of shell limestone give the facade a sophisticated appearance.

By incorporating concrete core temperature control, the building can be cooled or heated by the flow of temperature-controlled water through the concrete floors in summer and winter. Automatic sunscreens also help to maintain a comfortable working environment in summer. Energy efficient LED lights installed on the ceilings automatically adapt to the amount of daylight available, while foam ‘baffles’ provide excellent acoustics. The electrical installation uses the classic LS 990 design series in white from JUNG. A Facility Colour Touch Panel IP enables central operation of lighting, blinds, and heating or air conditioning systems, as well as other key functions, while KNX push-button sensors and BCU switches ensure convenient control of all KNX features.

The new and impressive headquarters of the Chamber of Commerce not only forms a link between the city and vineyard, it also signals the Chamber’s distinct and steadfast presence.
