As such, CMU, steel pipes, plywood, and charred wood were chosen that are easy to procure, and workable by hand. Wood charring process was done by the local farmers on site, which saved treatment and transportation costs. CMU walls attached perpendicular to the long front façade serve as buttress to the roof lateral load and add vertical rhythm to the elevation. The thin metal plate added to the top of the existing roof gives lightness to the building by exposing edges on the sides. The original room layout was kept intact with some minor additions.

The entrance to the lounge was treated with symbolic gestures. The exterior wall was demolished to create an inverted outdoor space to the entrance, and the wall section was exposed to show the construction of the wall materials – the original CMU wall, the steel pipe, and the newly added CMU. The manual roller shade is devised to shape string figures by pulling and winding the string around pins while opening the shade. The exterior light fixture and door handles are designed to enhance the atmosphere of the aged building and space. *The name Sumui (ㅅㅡㅁㅡㅣ) is a newly coined Korean word that mimics the shapes of the pitched roof, the eave, the square window frames, and the vertical CMU walls.
