[Text as submitted by Architect] At more than 20,000 m2 Karen Blixens Plads is one of the largest public squares in Copenha- gen. Situated between the University of Copenhagen and the Danish Royal Library’s buildings at the university’s campus, the open and welcoming urban space is an innovative, spectacular and multi-functional design that accommodates and promotes green transportation, climate change adaptation and biodiversity. The project was supported by a generous donation from the private Danish foundation A.P. Møller Fonden.
Innovative bicycle parking
The combined public square and university plaza is designed as a carpet that covers an undula- ting terrain of small hills and breaks the large space up into smaller zones with room for activities both on and inside the hills. The three bicycle hills were created as cast concrete shells clad with hand-laid tiles in colors echoing the exteriors of the surrounding university buildings.
In addition to serving as an active meeting place for students, employees and locals, the square also contains a high-capacity bicycle parking space for the many users of the university, includ- ing 16,000 students and 2,000 employees. The innovative and unique design has room for more than 2,000 parked bicycles.
”Copenhagen is one of the world’s leading bicycle cities, with more than 40 per cent of the city’s inhabitants riding their bike for their daily commute. That requires a new and flexible approach to bicycle parking. In previous projects we have developed innovative bicycle parking solutions that form a natural element in the environment. By Nørreport Station, for example, we create
the so-called bicycle beds, and here, at Karen Blixen Plads, the solution is bicycle hills. The integrated hilly landscape creates a space with a large capacity for bicycles, two-thirds of them in covered spaces inside the bicycle hills,” says Dan Stubbergaard, architect and founder of Cobe.
In a soft transition, Karen Blixens Plads brings together the university’s need for urban spaces with the open landscape of the neighboring commons. The north side of the square, where the three main entrances to the university are located, is an open and multi-purpose space. To the south, hilly, undulating meadowland connects the campus with the commons. In addition to bringing nature into the campus the landscape also contributes to climate change adaptation by adding a capacity to handle stormwater. Delaying rainwater in depressions in the landscape utilizes the recreational values of the water and creates small wet biotopes that support bio- diversity, enable rainwater evaporation and supplements the canal in case of extreme preci- pitation, thus contributing to climate change adaptation. The design uses simple, sturdy and durable materials, just as lighting and furnishings are kept to a few, simple elements to ensure a sustainable urban space. All the selected elements are low-maintenance and contribute to the square’s green profile.
A central feature is an outdoor auditorium with seating for up to 1,000 people on the manmade hills. The hilltops offer additional standing room for concerts or other large public events.
”All in all, we have created a unique urban space based on three main principles: improving the connection between landscape and urban space, integrating optimal green spaces with a large capacity for bicycle parking and creating a space that offers good social meeting places and learning environments. The almost cathedral-like form of the bicycle hills further offers an aesthetic experience in its own right, both when people park their bikes and when they meet at the hills for lectures, group work, concerts or Friday afternoon socializing,” says Cobe’s founder, Dan Stubbergaard.
