Infinite cityscape of grid panels Korean Society of Interior Architecture Designers (KOSID) and SPACE B_E (space branding firm) invited Archi@Mosphere and three other firms to partake in a design festival. This event engaged each firm to design a Pavillion, representative of their design ideology, in a 4M*7M*3M space. In designing space, details, which can be seen when observed, influence the overall experience of the space. Archi@Mosphere  focuses on bringing such details to finesse in the stage of development. In the festival, however, Archi@Mosphere gave a spotlight to the details as the protagonists. In the process of reversing the role of details, Archi@Mosphere designed a pavilion. It is composed of 45 grid panels of various scales and colors. Each panel consists of 8 large parts; each part has over 360 individual parts. Depending on the viewer's location inside, one can experience color transitions and panels that can serve either walls or ceilings. Some can be even deemed as furniture by its practical use. Then, a mirrored surface that box the Pavillion furthers the illusionistic effect of the infinite space of interactions.
