In the 1980’s this area was once viewed as a problem area – a large empty place without character. The new square now is an urban stage, interactive and changing, with the skyline as its décor. The Schouwburgplein is situated in the heart of the city and is surrounded by shops and flanked by the City Theatre and the City Concert Hall. The space is furnitured with 15 meter high ventilation towers from the underground parking and four hydraulic lighting elements. Their configuration can be interactively altered by the inhabitants of the city. The layout of the square is based on the expected use at different times of the day and its relationship to the sun. These sunlight-zones are reflected in the mosaic of the different materials used on the floor.The whole square is lifted 35 cm from ground level to enhance the stage-effect.
