As a backlash to the traditional introverted sports centre I designed, in collaboration with architect and industrial designer Marcus Vagnby, a covered tennis court, which from the outside showed the activities taking place inside the building. With its location in Sweden we used the faceted appearance of a cone as the inspiration to create a modular system that with its elements gave the building a living expression with exciting light and shadow experiences, made it extrovert and naturally well lighted, without compromising the main function - playing tennis.The project would be built in a new town, where all the buildings had to be built in wood, and it was here especially important for us to have a big focus on sustainability. We used wood in the bearing structures and the facade elements, had a well thought out natural lighting plan and used recycled rainwater to mention just some of our actions. Everything was made in interaction with the overall architectural idea of the cone.
