In order to extend the relationship between the shaped arc-shaped building and the interior, rippling spiral strings are placed in the space, with softly curved walls connecting the structural columns of the site, and large-scale curved holes are opened on the curved walls, causing a feeling of exploring a cave when people can travel through them. The natural elements also extend to the use of furniture, which is also the installation in the space, using natural stone and wood and organic curves to meet the function while conveying the space with a texture and language that fits nature.
