Danish architect Bjarke Ingels Group (BIG) has unveiled the design for a contorted bridge over the Randselva river outside Oslo.
The twisted structure will contain the Kistefos Museum, featuring works of art by Anish Kapoor, Olafur Eliasson and Fernando Bottero.
The 1,400 square metre "inhabitable bridge" will be located in a sculpture park on the site of a former paper mill.
Bjarke Ingels said: "We stumbled upon our first experiment with social infrastructure – a building that serves as a bridge – or a cultural institution that serves as a piece of infrastructure.
"A simple twist in the building’s volume allows the bridge to lift from the lower forested area towards the south, up to the hillside area in the north.
"The warped geometry of the building volume merges the vertical and horizontal in a single motion, forming a fanning staircase inside.
"The staircase doubles as an informal seating area, as well as an ideal space for video projections, performance art, and other such events"
BIG worked with consultants AKT II, Max Fordham, Davis Langdon and GCAM on the project.
Construction is due to begin next year and will be completed in 2019.
BIG has recently designed a foliage-covered residential project in Stockholm.
