Kengo Kuma's Kai Water Culture House Nears Completion in Copenhagen
The brick-clad aquatic center transforms Copenhagen's historic Paper Island into a cultural hub.
1Project Scope and Location
The Kai Water Culture House is a 5,800-square-metre facility located on Copenhagen's artificial island, Christiansholm. Known locally as Paper Island, the site is undergoing a major redevelopment. The project features ten indoor and outdoor pools, wellness facilities, and cultural spaces, serving as a new landmark for the city's waterfront transformation.
2Collaborative Architectural Design
Kengo Kuma Associates led the design alongside Danish firms Cornelius Vöge, Søren Jensen, and Vilhelm Lauritzen Architects. The structure consists of five staggered, pyramidal towers perched on a glazed base. This design integrates a wooden pier providing direct sea access, effectively bridging the gap between industrial history and modern recreational use.
3Materiality and Brick Construction
The building's exterior is constructed from 300,000 handmade bricks arranged in a staggered, stepped pattern. This choice provides a distinct sculptural character and texture to the tapered volumes. The brickwork serves both an aesthetic and functional purpose, defining the building's identity while anchoring it within the surrounding urban harbor landscape.
4Light and Spatial Dynamics
The facility features 403 windows of varying sizes, acting as viewing apertures that frame the harbor surroundings. Triangular and square openings in the brick volumes filter dappled light into the indoor pools. These apertures create shifting natural light patterns throughout the day, enhancing the sensory experience for visitors within the aquatic center.
5Functional Tower Distribution
The five volumes serve distinct purposes within the complex. The tallest structure, the Culture Tower, hosts cultural programs and a third-floor events space. The remaining four towers are dedicated to housing lofty indoor pools. This vertical distribution allows for a clear separation between high-activity aquatic zones and quieter, community-focused cultural programming areas.
6Wellness and Outdoor Amenities
A key feature of the design is the outdoor pool nestled between the brick volumes on the first floor. The facility also includes an open-air Onsen, a Japanese-style hot spring overlooking the harbor. These spaces are framed by the building's sloped facades, creating an intimate connection between the users and the water.
7Broader Island Redevelopment
The Kai Water Culture House is part of a larger redevelopment of Paper Island led by the Danish studio COBE. Recent projects in the vicinity include a 20,000-square-metre apartment complex inspired by the island's 300-year-old warehouses. This development strategy aims to preserve historical context while introducing modern residential and recreational infrastructure.
8Timeline and Strategic Impact
The facility is scheduled to open to the public on December 5, with the wooden pier completion expected early next year. This project marks a significant shift in Copenhagen's harbor identity, moving from industrial utility to a community-centric cultural hub. It serves as a focal point for public engagement with the water.
