Hartwall Arena is the largest sports stadium and entertainment complex in Helsinki. The infrastructure of the arena is dimensioned to meet the peak demand during large public events. This happens 2-5 times per year in events such as major ice hockey matches and rock shows. For the remaining time the vast potential of the arena remains unused. The unused infrastructure could supply for another 50.000 square meters of new construction.
We propose a new building on site to take this potential into use. Peak attenuation systems help to overcome the large public happenings. Simultaneously the rough public space around the arena is upgraded from an empty asphalt field into an exciting landscape of action. Site conditions provide clear starting points making tall building the only sensible approach. The proposed tower is close to 120m tall consisting of apartments, offices, and a rooftop restaurant with a viewing deck. The podium contains a sports centre with various sports programs. The roof of the podium extends the current deck surface of the Leijona square providing for the public space in terms of green landscape and various sports uses like basketball and wall climbing.
The arena is separated from the surrounding city structure by two railways and massive road networks. They provide access for the stadium and the new project, and also cause the lack of neighbours who might potentially be disturbed by a tall building nearby. The project is a strong contribution to densification and diversification of the existing urban fabric of Helsinki. By building on the bad we can add quality, usability, visibility, connectivity and sustainability to the area and the whole city of Helsinki.
