The project attempts to develop a typology of public toilets for highways. In order to facilitate the travellers, the project is designed as a refreshing facility with amenities such as an ATM machine, free WIFI, bathing, changing rooms, mobile charging station, changing station for mothers with infants and a sanitary napkin dispenser. The project scoops out a central void within the toilet block to form an arrival and waiting plaza. The key issue concerning toilet is the odour, which is a result of poor maintenance and lack of natural light and ventilation. This project develops a modular skin which, through its geometry, enables continuous natural light and ventilation within the toilet block. The skin is made up of triangular pre-fabricated modules that can be mass produced and put together through dry construction.
