Interior Space and Exhibition Design Rotunda Sale Center by Kris Lin Rotunda is a sales center interior that also serves as a clubhouse and exhibition space. The design is organized around a central circular hall, which acts as the visual focus and connects the meeting rooms, lounges and offices. A waterfall-inspired lighting feature illuminates the hall. Iridescent glass panels and mirrored ceilings shape the atmosphere, and the glass is recyclable. Large glass panels were bent to follow the curved walls. The open and fluid layout supports art exhibitions and social interaction.
