The new national theater follows the model of a Viking-era longhouse. Historically, these buildings served as communal spaces for multiple families. The theater adopts this concept, centering around a large common hall with private rooms around it. Its classification depends on its spatial organization, not its length.

The theater’s design integrates historical context through its lateral development and central hall, reflecting the longhouse typology. It aligns with the existing urban fabric, using original foundations to define its position. The main entrance, foyer, and forecourt follow the site’s topography, establishing a strong connection to Schleswig and the Schlei.

A telescopic grandstand ensures flexibility in space usage. The event hall can be divided into two separate areas or used as one large space. Seating configurations adapt to different performance needs, either as a fully seated hall on one level or with tiered seating for better visibility and engagement.

The theater provides diverse spaces for culture, art, and community interaction. Both interior and exterior areas form distinct zones at different levels. The generous foyer spans all levels, ensuring accessibility. These spaces promote engagement, fostering a dynamic cultural hub while maintaining an open and inviting atmosphere for visitors.
