It is a plan for a small beauty salon with a complete reservation system, which is a renovation of one room in the building. One circular furniture that aggregates functions was placed in the center of the room, and while properly blocking the line of sight from the entrance, the sign (light/sound/wind, etc.) can be felt anywhere. Have a cut while looking at the sky through the mirror, and receive a head massage while listening to the faint sound of the city. The one-action intervention of placing one circular furniture made it possible to create a rich space unique to this place.
