Designing urban areas to be resilient and liveable

The huge transformation of Høje Taastrup C on the outskirts of Copenhagen demonstrates how we can create attractive and climate resilient urban areas. The big draw is a rainwater drainage system that doubles as the world’s longest skatepark.
Høje Taastrup C has gone from wide boulevards and clearly divided zones to a coherent, dynamic urban area with a great flow between housing, nature, cafés, traffic, and recreative spaces.
COBE has developed the architectonic design that allows residents, nature, city life and infrastructure to interact and benefit from one another. As main engineer consultant, Ramboll is responsible for planning and implementing this visionary project.
Ramboll has, among other things, been responsible for an extremely complex relocation of existing wires and pipes (water, electricity etc.). Ramboll has also led the planning and execution of all project phases, risk analysis and management, planning and execution of Sustainable Drainage Systems (SuDS), stakeholder management and much more.
Rethinking what makes urban areas liveable and inclusive
Høje Taastrup C stands out as a prime example on how to design urban areas suited for the future. The project is accommodating a need for housing and climate resilience, but also includes the aspect of social and economic sustainability. The design reflects an overall consideration of what makes a place attractive to live in, and how to design a public space that provides the best conditions for social inclusion and recreational purposes.
The result is a public park of 42.000 square meters that includes the world’s longest skatepark, climate adaptation, playgrounds, benches, fruit trees, and an advanced lighting design that will ensure lighting at all times for people to feel safe.
Circular use of materials and water
To increase the level sustainability of the project, Ramboll has reused material from previous infrastructure, making sure to decrease the carbon footprint and save resources. 5000 tons of concrete from old bridges have been crushed and reused as road base and dredged soil has been incorporated in the implementation of the green areas of the park.
Høje Taastrup C is also an amazing example of brilliant climate adaptation. To optimize the water management, separate rain- and wastewater pipes have been placed across the area. Now, rainwater will travel through rain gardens down to the park area and on to an open rainwater pond. From there, Ramboll has established an irrigation system that will use the collected rainwater to irrigate the park. During heavy rain, excess rainwater will be led from the rainwater pond to the skatepark that also serves as a detention pond.
The skatepark has a capacity of 6500 cubic meters and runs approximately 1 km, making it the world’s longest skatepark. It can handle up to a 10-year rainstorm on a daily basis and up to a 100-year rainstorm during cloudbursts. The skatepark will thus help lead and detain rainwater, while serving as a great recreational space for current and future residents and visitors.
Høje Taastrup C is already proving to be an extremely popular area, and all building plots for new housing have been sold, with the majority now being under construction.
