The University Library does not only make a spectacular architectural statement with its building, it also provides excellent service and an optimal learning and working environment for its users. The full renovation of the University Library took place from 2009 to 2015. The building was designed by architectural firm Degelo Architekten in Basel. They used an innovative lighting, energy and air-conditioning concept to give the building a new, transparent façade made of metal and glass. Heinrich Degelo, the architect behind the design, calls it a polished diamond.
The building is known for its openness between the mostly freely accessible stacks and the reading rooms on the upper floors, with more than 1,750 separate user workstations, ranging from quiet zones to learning lounges. The library is open seven days a week and offers modern facilities. With up to 16,000 visitors per day, it is one of the most frequently visited facilities of its kind.
