A renovation design project for Bangkok’s underground shopping mall, Metro Mall, located inside the MRT underground train at Petchaburi Station. When it comes to underground space we would like to contrast the feeling of being ‘underground’ with something more bright, cheer up and positive by added them into floor patterns, ceiling, lighting and fun graphics. Since the location surrounded mainly by schools and office buildings. We reflect that context on the graphic design that spreads inside the mall. Hoping that people will come and able to feel this place as a “Happy Hub of MRT”.
