As a backlash to the traditional introverted sports centre I designed in collaboration with architect Peter Sand a covered tennis court, which from the outside shows the activities taking place inside the building. With its location in Sweden we used the faceted appearance of a pine 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 pine cone.
