A modular structure
The Danmarks Nationalbank building consists of narrow modules measuring 420 x 420 cm as the load-bearing structure, partly with a view to reducing the construction height and making room for an extra storey without the building becoming taller than the neighbouring blocks. The modules are visible both on the façade and inside the building, e.g. in the office corridors with double walls of cupboards, on panels and in the IT floor of the banking hall.
Curtain wall
The façade of the Danmarks Nationalbank building is based on a "curtain wall" principle, which means that the façade has been mounted on the building without being part of the load-bearing structure. That was very innovative at the time.
