Twisted art museum by BIG to be built across a Norwegian river

Bjarke Ingels' firm has won a competition to design an art gallery for a Norwegian sculpture park, with plans for a building that twists across a river (+ slideshow). Described by Ingels as an "inhabitable bridge", the Kistefos Museum will span the Randselva river that winds through the centre of the Kistefos Sculpture Park near Oslo.
