➜ Short description

The Little Big Loo - Rethinking Public Toilets invites ideas that can be used to disrupt the perception of public toilets with the most innovative and efficient solution for this serious issue plaguing our future. This necessary public utility is to be designed in a way that changes the overall outlook towards public washrooms.

The designed area can be recreational, educational, social; a space that creates value for the community surrounding it. The space should be visualized as a prime component in the making of a community that develops holistically; a community that is competent in social, economic and educational terms.

Participants should unlearn how a conventional public toilet looks like and design an innovative, functional and visually appealing design that serves as a building icon, synchronizing with the surrounding context.

The primary use of the designed structure should be as a public toilet. Alongside this, the structure should be innovatively designed as a space for community interaction, in addition to its primary function. The space should be additionally visualized as a recreational/ educational/ social/ urban functional area.

The total area of the space should not exceed 150 sq.mt. All age groups of the demography should be able to use the space.

The additional space aspect of the toilet should add value to society and the site’s context. The design should be efficient in terms of planning, hygiene, odour-free surrounding and space usage. The designed toilet should be accessible, comfortable/ convenient to use.

The design intervention should be aimed to address the efficiency of public restrooms, their sanitary facilities, spatial distribution and mainly, privacy and comfort, which ultimately improve peoples’ lives.

The design can act as a module, which can be replicated in different areas similar to the site context chosen. The design should be capable of catering a footfall of 250-500 people.

Participants can select a site in an urban OR a rural context. There can be an emphasis on deprived locations, irrespective of the site being in an urban or rural area.

The site should be carefully placed to accommodate the number of footfalls (circulation in transit hours must be considered). It must be justified with the need for sanitation services.
