The design starts with the existing two trees on the platform. By method of avoiding or enclosing the trees, three courtyards in different levels are formed thereby to expand the view and to have an opposite scene. Equipped with corresponding functions in different courtyards, the courtyards become quiet and exclusive spaces and an idyllic place where tourists feel themselves far from the noisy cities. The repetitive transitions of corridor stretching from south to north interpret a classic Chinese gardening concept that the visitor may have varying sceneries with changing view-points.
