Interior Space and Exhibition Design Plus 81 Bar and Club by Takahiro Todoroki Plus 81 is a bar and nightclub interior set within an aging shopping mall. The facade resembles a temporary construction site clad in Japanese newspapers, and the entrance is concealed behind a figure shop, creating a gradual transition into the interior. A central bar anchors the layout, while surrounding zones support dining, lounge seating, karaoke and private gatherings. A grid ceiling with RGB lighting responds to the low ceiling height and adds visual rhythm. Materials include zinc-galvanized steel, etched mirrors and resin flooring with graphic typography.
