A new landmark will soon be lighting up Copenhagen harbour! Already nicknamed “The Opal” for its reflective and luminary qualities, the expectations precede the actual building. The new extension has an almost weightless quality that seems to suggest that gravity has somehow ceased to exist on this prominent spot at the center of Copenhagen harbour. An intrinsic light design will allow for the surface of the building to mirror the play of colours of the water in the harbour – thereby adding a touch of splendor to an otherwise unglamorous part of the harbour.

The light design is made possible through a visionary design concept developed by Dorte Mandrup and the engineers from Søren Jensen Rådgivende Ingeniører.

According to the jury, who chose Dorte Mandrup’s design as the winner of the competition in August 2016*, the Opal offers a “unique architectural approach for creating a visionary and distinctive new landmark for IDA's headquarters. The building has great potential to become a focal point for illustrating the symbiosis between the art of engineering and architecture. Both IDA and Copenhagen will benefit greatly from the new addition”.


The design concept allows for the building to rest on just four V columns made of steel. The triangular surfaces of the facade alternate between transparent and opaque and the technical textile cladding incorporates LED lights allowing for a spectacular staging of the building at night.
