Building the future of nature based resiliency

How can we address the immanent threats of rising sea levels derived from climate changes, the urgent need to repurpose surplus materials from the building industry, while envisioning the creation of new development areas with recreational spaces?

The answer unfolds in the form of Lynetteholmen: A future-forward neighborhood emerging as a key factor in Copenhagen's climate and flood protection strategy. Situated as an island in the Copenhagen area, Lynetteholm signifies a bold commitment to proactive climate resilience, transcending the conventional notions of urban planning.

Lynetteholmen is filled with surplus soil from construction sites in Copenhagen and the surrounding areas. This ensures that Lynetteholmen becomes a guarantee for Copenhagen Municipality to make beneficial use of the surplus soil for decades to come. Soil filling directly in Copenhagen gives the advantage of reusing the soil close to where it is excavated, minimizing transportation, and consequently lowering CO2 emissions, while creating a whole new development area in the Capital region of Denmark.

275 ha
New land
By receiving surplus soil from the Capital Region starting 2023 the island is expected to be finalized in 30 years.
Key numbers
35.000
Inhabitants in 2070
The island will allow for an estimated 20.000 new homes and 35.000 workplaces
60 ha
Public coastal landscape
A public nature-based coastal park on the outer perimeter of the island future-proofs Copenhagen against storm surges.

Perimeter complete 2026
The construction of the stone perimeter dam is made using waste storne material from Norway and is to be completed in 2026.
Establishing a new urban nature

A crucial element of Lynetteholmen is the establishment of a climate- and flood-protected dock-gate at the Northern harbor entrance, serving a dual purpose: Shielding against environmental perils and laying the foundation for a nature-based urban development, merging ecological responsibility with urban innovation.

Lynetteholmen envisions an expansive and robust coastal landscape dedicated to nature-based climate protection. This protective belt not only serves as a defense against temporary high water levels and permanent sea level rises but also fosters a rich natural habitat. The variability in width, curved coastline, and diverse ecosystems create the foundation for a species-rich natural area, offering an immersive and unique nature experience both above and below the water's surface. It is a structural approach to biodiversity, where we rely on nature’s own systems, using these to foster an acceleration in biodiversity.

Connecting the city with nature

The project of Lynetteholmen creates not only climate adaption for of residential and commercial spaces. The neighborhood's commitment to fostering a cycling culture and integrating a metro line connecting to Copenhagen's center underscores a dedication to collective transportation, aligning seamlessly with the broader vision for an interconnected and regenerative urban future.

Lynetteholmen's design ensures that every resident and visitor is in close proximity to the coastline, fostering a profound connection with the natural environment. Lynetteholmen showcases a forward-thinking approach, where cities can proactively integrate nature-based solutions to combat climate challenges while simultaneously nurturing vibrant, regenerative communities.
