This project located on the Road intersection (Beihuan Road and Yiyuan Road), architects designed a border-less plan layout making the nasty toilet blank out behind greening surrounded, assimilate into nature. Boundary between architecture and nature becomes ambiguous. Working as a shortcut towards the park, it includes several leisure seats for passengers to rest and wait. 8K mirror stainless steel is adopted as facade material that varies along with different time and lighting. Architecture is integrated with surrounding in harmony and fading behind nearby forests at the same time. Besides,passengers also play a part in the appearance of facade, while the toilet is vitalized and being an infectious art installation.
