Facade Handover:


„In pursuit of the classically modern tradition“

The project comprises of approximately 1.500 m² fully glazed ribbon glazing together with exposed concrete balustrades emulating an office building, which on behalf of Roche Pharma AG was given the project name of “Opal”.

The façade is composed predominantly of linear supported triple insulated glass with a weight of up to 750 kg. Factors which particularly distinguish this project include its challenging installation logistics which were closely coordinated with the shell construction contractor, as well as the various special glazing solutions needed for the construction.
