Recreational Structure in Hylkedalen

The project aims to protect Kolding’s city centre from flooding by temporarily retaining large volumes of rainwater within Hylkedalen. Two transverse earth embankments create a passive damming effect on the Seest Mølleå stream, allowing it to overflow into the valley during heavy rainfall events.

As part of the project, we collaborated with NIRAS to design a recreational structure positioned centrally within the valley— a cultural element nestled in nature where visitors can pause, sense the shifting landscape, and experience the site from a fresh perspective. The structure simultaneously functions as an integral part of the technical infrastructure; it manages water overflow and safeguards the valley banks. Constructed from dark-pigmented concrete and timber-clad surfaces, it appears as a calm, embedded form within the open valley landscape—inviting presence without disrupting the character of its surroundings.

This extensive climate adaptation initiative is developed by Kolding Municipality and BlueKolding A/S, and its strength lies in the interplay between function and narrative. The climate resilience measures are not hidden necessities but are embraced as part of the landscape’s renewed identity. Materials have been selected with sensitivity to the environment—drawing inspiration from the earth’s natural tones and employing a design language that firmly anchors the structure to its place.

Additionally, the project delivers a range of ecological and recreational benefits: restored meandering streams, new ponds, and wetlands enhance habitats for amphibians and the rare birch mouse, while extensive grazing promotes biodiversity across the open natural habitats.

For local users, Hylkedalen has become more accessible and rich in experiences. An expanded trail network, mountain biking paths, training facilities, and a new trail centre at Seest Sports Ground generate activity and cohesion. On the eastern embankment, known as the “Bottle Neck,” rest areas with views over the valley have been established—places where technical infrastructure helps to create a new spatial landscape.
