As a stunning answer to the Royal Danish Opera House across the water, the Royal Danish Playhouse sits in a prominent location on Copenhagen’s harbour front. Its structure is about the interplay between three compositional elements: an oak-clad promenade standing above the water; a brick stage building and copper-clad tower; and the green glass of the building’s overhanging first floor, which gives the actors and production team spectacular views.

For this striking building’s high-traffic toilet facilities, d line products play a reliable supporting role to a dramatic black interior punctuated by lipstick-red doors and bulbed, dressing room-style mirrors.
