Café Loge is located on the first floor of a typical office building in a commercial area in East Pangyo, Republic of Korea. The upper part is enveloped with a curtain wall, and the lower part is covered with a dark stone finish, transparent glass, and an exaggerated sign, so it represents a newtown but dry commercial street. Café Loge needed to get out of this existing commercial street, boldly. A boundary of unconventional space was made in the dull city center, using arches that could have firm formal vocabularies based on white mosaic tiles with a solid, strong property instead of transparent material called glass, and through the glass arch, bluish green colored interior space and nature in the raw could be seen from the street.
