Renovation of a three-story building located in Minami-Aoyama, with one basement floor and three above-ground floors. The residential portion, previously occupied by the owner’s two households, has been converted into office space. Two tenant spaces have been prepared on floors 1 to 3.

While keeping the tenant spaces as simple as possible, the insulation reinforcement areas on the outer perimeter are deliberately highlighted by incorporating colors extracted from the existing exterior walls and contrasting them with the existing concrete. The entrance incorporates design elements that reveal the characteristics resulting from the removal of the upper transom, which is one of the features of a residential setting, and the flattening of the floor (revealing the repair lines caused by the floor being lowered and the foundation of the staircase). During the renovation, areas that are typically treated negatively, such as repair areas and concealed parts, when existing elements are dismantled, are turned into design focal points. The interior design was planned to fill the existing framework with new elements.
