The Lonza skyscraper in Basel is a striking, 68-meter-high, 19-storey administration building owned by the Lonza Group . The high-rise is part of the inventory of buildings worthy of protection and is therefore under protection of cultural property .
history
The building was built between 1960 and 1962 by the two architects Hans Rudolf and Peter Suter from the architects Suter & Suter. The skyscraper was occupied on July 29, 1962. At the time of moving in, it was the tallest building in the city . At the same time, the F. Hoffmann-La Roche company and the Geigy and Ciba high-rise buildings were built.
On May 10, 1970 there was a fire in the evening as a result of an insulation defect in the line of a fluorescent tube on the 7th floor. A plexiglass cladding burned in a short time, accessing the aluminum cladding, which was partly made to burn and partly to melt. The fire brigade was able to put out the fire within three quarters of an hour. There was material damage of several 100,000 francs.
In 1999, extensive renovation work was carried out in several stages. In 2011, a decision by the city commission caused a sensation, which initially rejected the request to install solar systems on the Lonza high-rise. This would significantly obscure the overall concept of the building design of the listed building, so the reasoning. This decision was later reversed.
description
location
The Lonza skyscraper is located in a park-like area not far from the Basel SBB train station . The triangular property is framed by the busy Nauenstrasse, Grosspeterstrasse and Lindenhofstrasse. To the north of this is the Christoph Merian Park and the Rosenfeld Park. In addition to employee parking spaces, there is also a tennis court on the property. The long side of the high-rise has a north-south orientation and is therefore almost at right angles to the railway line running south of the high-rise.
Architecture and construction technology
The 68.4 meter high Lonza skyscraper is a concrete construction with a curtain glass facade and an outer skin made of Grinatal sheet metal made of ribbed aluminum. Light gray vertical structuring elements contrast with the somewhat wider black parapet elements. The facade covers around 7,000 square meters. The floor plan of the high-rise measures 45.3 by 14.85 meters. The stairwells and other necessary infrastructural elements are located in the sloping, tapered side parts. These external design elements earned the skyscraper the name razor . In addition to the 19 upper floors, the high-rise also has three underground floors.
To a certain extent, the stress caused by earthquakes was also taken into account. The stress is around 150% of the maximum wind attack. The house withstands a total of 400 tons of wind pressure and has a largest bend under wind of 1.9 centimeters.
The sober but delicate facade is still rated as the timeless quality of this architecture and is often compared with the Pirelli high-rise in Milan .
