The main entrance of the building is located on the west side of the roof, with a semi-circular shape that extends from underground. From here, people can enter the interior of the building through the descending passage. The interior of the building is composed of multiple interconnected “cave” spaces. The architect drew inspiration from the surrounding sea eroded landforms and created an organic and dramatic space through mimicry.
