The former railroad repair plant in Munich-Neuaubing now forms part of a business park just outside of the Bavarian state capital. To renovate Werkhalle 3 in line with heritage protection requirements, the architects opted for Janisol Arte 2.0 from Schüco Jansen Steel Systems. Using this slimline glazing bar system, it was possible to upgrade the historical industrial glazing while preserving the characteristic appearance.
The so-called “Werkhalle 3” (“Workshop 3”) is one of the oldest buildings on the site of the railroad repair plant, which was built between 1912 and 1918 in Munich-Neuaubing. It is a reinforced concrete building clad with bricks, which was put into operation in 1906 as a carriage repair workshop and continued to be used up until the early 2000s. After the railroad repairs moved out of this location, project developer Aurelis Asset GmbH took over the premises, including the halls that had been listed as heritage protection sites since 2008. Werkhalle 3, which was formerly used as the “western carriage repair workshop”, has a floor area of around 11,000 square metres, making it the second largest of the historical halls. The existing floor area of the structure, which is up to 11.5 metres high in places, has been expanded by more than 2000 square metres by installing galleries. As part of the conversion into office and commercial units, the architects responsible for the renovation – Fischer + Steiger u. Partner Architekten mbB, Munich – arranged the structures into four independent areas, which are connected to one another by an inner courtyard. The exposed brick façade was retained during the renovation, as were the characteristic arched-head windows.
Authentic renovation of an iconic building
“The renovation of these historical halls required all of our flexibility and creativity,” said Heinz Fischer, from architectural practice Fischer + Steiger u. Partner Architekten mbB, Munich. “One challenge in particular was combining sensible structural and technically contemporary solutions with the heritage protection requirements.” Due to the structure's listed building status, the single-glazed steel profiles of the large industrial glazing were repaired wherever possible, and a thermal window layer was added on the inside. For the reconstruction of the missing windows, the architects opted for Janisol Arte 2.0 from Schüco Jansen Steel Systems. Extremely narrow
face widths and excellent performance values characterise the thermally broken steel system. By using narrow steel glazing bars, it was possible to construct the new steel-framed windows with triple insulating glazing in the desired slimline look.
Transformation of the existing properties
Following the renovation, the turn-of-the-century industrial architecture now conceals state-of-the-art technology. Heat is supplied via district heating from a nearby geothermal plant. New internal thermal insulation as well as the installation of an additional layer of insulating glass on the inside help to make sure that the valuable, historical fabric of the building can be used in an energy-efficient way. The project is an excellent example of the potential that lies in the conversion of existing properties: with comparatively low CO2 emissions, the construction has gained another life cycle. Together with the future-proof concept of use, it has been possible to increase the value of the property and preserve a piece of railroad history for the future.
