By the requirement of the Municipal Council of Prague 7 to revitalize the neglected subways at the Vltavská metro station in Prague, we proposed the transformation of a dark "no-go" zone into a shared streetsports area. The basic technical idea was to avoid reconstruction and to implement new elements into existing structures. The operating idea was not to separate the sports from the transport function of the subway, but on the contrary to contribute to the sharing of public space. Safe and "friendly" zone, accessible 24/7. Skateboard and BMX obstacles, boulder wall with overhang, basketball hoop, bistro, servis point and amphitheater. Permanently lit space under the roof. Browsing supplemented with meeting options.
We believe in the concept of a cohesive city, within which we try to blur the barriers between functions and individual groups of residents and visitors. The solution we propose has the ambition to promote freedom, openness, safety and sharing. And in accordance with the requirements of the hot present, we believe in the power of sport as a medium for personal development and intergenerational and intergender communication.
Similarly, there are countless "sleeping" places in Czech cities. You just have to want to change them.

A concrete floor (smooth for users of roller sports, but at the same time respecting the comfort of pedestrians and cyclists) and concrete obstacles were implemented in the place of the underpasses. A boulder was placed on the existing bridge structure (concrete overhang was used) and a workout trapeze. In place of a natural "amphitheatre", the existing concrete cascades were used as an auditorium and a basketball hoop was placed in the middle. In the part of the underpass near the amphitheater, a bistro in the form of a bus with service point has been located since spring 2021. The area is equipped with new lighting (outdoor and indoor), which allows riders to use the area in any weather and time of day.
Due to the nature of the building, the most durable materials are chosen - concrete and metal.
