Besides the main stage, the building also includes a small stage for experimental theatre, a so-called "black box" theatre called Takkelloftet. It was named after the original Takkelloftet, a building just south of the Opera 280 meters long and built between 1767 and 1772 for storing ropes for the navy. Thus the opera maintains a connection to the marine history of its location.
Everything on the stage and in the audience area is totally black, and the audience's seats can easily be removed in order to make the room much easier to configure for alternative setups. There are up to approximately 200 seats for this stage.
Takkelloftet has its own foyer. In this room, some of the walls are decorated using the same Jura Gelb limestone as outdoor. These stones are mounted on the wall in a way that makes it possible to use the stone plates as a kind of music instrument just by knocking on them with bare hands.
