Biology museum near Porsuk River represents the organic structure of a living organism. Using many biological references, the concept of fluidity defined the interior forms. And the exterior form was the result of interior decisions. Just like the interior of a living organism, there is no linearity. The circulation is through the guidance of curves, with the experience of the organic atmosphere inside a living organism. The interior columns and entrances mimic the microscopic section of bone tissue(biomimicry). Having a similar form, a stretched slimy gum has been an inspiration for the bridge. The façade entrance is designed referencing the curvaceous forms of intraoral structure.
