The city of Busan contains two characteristic sights watching the city from above. Firstly the mountains. The city structure surrounding the mountain area with its organic areas and streetlines is strictly ruled by the form of the mountains. The second topic is the Pacific Ocean shore for which a masterplan already exists. The challenge of the competition is to connect the old city with the new shoreside through the space of the main station by showing a possibility to develop the masterplan of the harbour.
