Stunning designs have been revealed for Copenhagen's new Water Culture Centre, which will feature outdoor and indoor pools, waterfalls, harbour baths and sports facilities.

The municipality has selected Kengo Kuma Associates to create the 5,000sq m (53,800sq ft) Danish Water Culture Center, scheduled to open in 2021.

Copenhagen mayor Frank Jensen said: "There's no doubt that Kengo Kuma’s vision for a waterfront cultural centre is world class and that it will bring something completely new to Copenhagen but will also fit in with the aesthetic of the city.”

Kuma’s design envisions the building as having a series of pyramid-shaped roofs, with an open-air pool passing through the gaps between them.

The project will be built on Christiansholm Island, one of the last undeveloped areas along the city’s waterfront. It has been used over the past 50 years by the Danish press for newspaper storage, inspiring the nickname ‘Paper Island’.

The Danish Water Culture Center is part of a wider masterplan for Paper Island created by architecture firm COBE.
