Description / Additional Information
Describe the key innovation and technology aspects of the project
Project Narrative
The initial library, dating from the 70s showed architectural and energetic deficiencies and had to be rebuilt. By cutting away parts of the building, Degelo Architects not only reduced the disproportionately large volume of the old library, but also made the building react to its urban context. Thus the building became a cut diamond. The façade of this crystalline sculpture is composed of electrochemically treated chrome steel. The façade sees itself as an interface, which communicates between university and city.
