Space Untitled is programmed to lend some space that can adapt various stories. Thanks to the program’s characteristic, we expressed Space Untitled itself in the space, which means there’s no title. The existing frame of architecture and the stories of Space Untitled are well connected as one sequence. We directed a scene according to the function of drawing and it is the essence of Space Untitled. It is our first impression that there’s no exact distinguish between outside and inside when we first come across it. Even though it is located in the basement, the extraneous light comes into deep inside and the inside become full of light. The boundary means another dimension and the dimensional boundary starts from the dot and the line. This is the basic frame of the space as well as a factor of space interpretation. It is designed in the middle of existing architecture structure, horizontal and vertical and also by adding aesthetic function, the furniture and architecture are built similarly. We connected inside and out space by the light directly from the ceiling to express natural elements like light and shadow in the main space where people gather together and spend most of time. There is a boundary by the light and the space facing the boundary is designed to carry light in the darkness and make various darkness in the basement space. Therefore, users can feel the natural light in the middle of darkness.
