Copenhagen to turn into a landmark harbor swimming destination in 2026

The Water Culture House on Christiansholm – better known as Paper Island (Papirøen) – is set to become one of Copenhagen’s most exciting new waterfront attractions when it opens in the second half of 2026.

Part of a wider vision for the island, the project anchors the development of PAPIRØEN, a brand-new urban district designed as a relaxed oasis in the heart of the Danish capital. The area will blend water culture, dining, housing, and public spaces, inviting people to unwind, experience culture, enjoy good food and take in sweeping views over the harbor and inner Copenhagen.

A structure wished by Copenhagen residents

The Water Culture House itself is described as a gift to Copenhagen residents and visitors alike. It will offer a unique swimming experience right in the Port of Copenhagen, combining innovative design with year-round indoor and outdoor aquatic facilities.

The concept was born from the public. In 2015, the City of Copenhagen launched a competition inviting residents to propose ideas for a new recreational and cultural center on Christiansholm. The majority called for a swimming facility — underlining Copenhagen’s deep connection to its harbor.

An international tender for the design followed in 2017. The winning team was led by Japan famed architect Kengo Kuma & Associates, alongside Danish companies. The overall island redevelopment began in 2018, representing a total investment of US$124 million (DKK 865 million).

Japanese-style contemporary architecture

Located on the northwestern corner of Christiansholm, the building will introduce a striking Japanese-inspired architectural expression to Copenhagen’s harborfront. Designed as a cluster of cone-shaped brick volumes in soft grey tones, the structure will appear to rest lightly on a ribbon of glass.

The standout feature will be a heated outdoor pool set within a “valley” formed by the roofscape, delivering a one-of-a-kind bathing experience with harbor views. Additional outdoor pools of varying depths will sit close to the quay, catering to both adults and children.

The Water Culture House will span up to 5,000 square meters and include swimming facilities, club and association spaces, a promenade, meeting rooms and community areas, positioning it as both a leisure landmark and a social hub. No precise date for the opening has been so far provided but it is confirmed that it will be available for the public in the second half of 2026.
