366 Kashiracho is a minimal renovation located in Kyoto, Japan, designed by NAAD. The purpose of this renovation project of a late nineteenth century building in Kyoto is to renew the reception area of a guesthouse, Kaikoan, and to create a new space for a costume rental shop. Due to the differences of programs, the upper level and the lower level bring distinct atmospheres to the users. The lower level, which is used for the reception, is a public area of the building and has a more open atmosphere. The existing columns and beams, which were formerly hidden behind panels, are now exposed with a continuous white painted wall. The new wall is featured with rounded corners and wraps around the columns.
