A design proposal for the new Oslo opera House. The multiplicity of the building program covering an entire range of genres – from opera, ballet, musical theatre and dance productions to operettas, concerts and guest performances, is all veiled under a prominent urban skin, a landmark in the city of Oslo facing the harbor. The configuration of the urban curtain foregrounds even more its effect over the skyline of the city of Oslo. The skin of the building folds into itself to generate a Pormanesque atrium to bring light in the entry of the opera house and add a sense of drama appropriate to the species of opera itslef.
