Dorte Mandrup Arkitekter won the competition to design an extension for the headquarters of the Danish Society of Engineers (IDA). ‘‘The Opal’’ will form part of the scenic Copenhagen Harbour, accommodating a conference hall and restaurant. Of all shortlisted designs, the IDA stated that The Opal best-reflected "[their] vision of engineering."
The eye-catching design alludes to the gemstone it is named after, which reflects light to take on multiple colours. This reference is seen both in the structure and form of the new addition to the Copenhagen Harbour.
