On the 2nd of October 2022, the third edition of Roca One Day Design Challenge was celebrated at PAM Centre in Kuala Lumpur. This edition of the contest attracted over 300 students from all over the country, who participated in a design race against the clock. 

Nowadays, all major cities are facing the necessity of installing public toilets, which would improve cleaning and hygiene conditions, as well as improve quality of life in neighborhoods. In this context, the participants were challenged to design an urban public toilet, which apart from the above-mentioned characteristics would also be feasible in function of maintenance and economic installation. 

This year’s title was claimed by Pang Jian Sheng, who won MYR8,000 thanks to his project Flower Pot, which consists in a spacious toilet well-integrated into its environment. The design includes a self-sustaining micro-ecosystem that provides for the basic needs of the flora that live on it.  The jury valued its celebration of the natural world and the way it conceptualized humanity’s connection to nature.

Second prize was awarded to Tengku Amirah binti Tengku Johari for her Gnuyap  project, which has brought her MYR5,000. Gnuyap features a toilet, which is perfectly integrated into the urban landscape, with emphasis both on form and function.

Alison Leong and Belle Chin from the One Academy have been granted the third prize, receiving MYR3,000 for designing a piece of remarkable flexibility. Their design The Orbit is a portable public restroom, conceived as a simplistic circular space with an overall harmony between form and function, which blends within its surrounding through its play of external features.
