The relationship between formal and informal settlements is a major component of this project, therefore how a wider, uniform system interacts with the irregularity of informal space is paramount when understanding efficiency within the slum context.

Slums typically lack a defined layout, thus by developing an arched pathway for multi-level access to various programmes, boundaries which frame the interventions informality with efficient access to pathways and public space can be created.

The layering of various programmes within a singular structure will result in significant confusion when trying to differentiate various functions in relation to their entry and exit points, thus ornamentation will define the system's hierarchy.

Multi-vernacularism defines the function of both enclosed and open space while also being a means of celebrating Egyptian culture. Ornamentation alongside the use of exposed brick serve as a testament to the ever-changing nature of Cairo's slums.

Shared infrastructure and open space become the interface for various programmes to develop symbiotic relationships. Thus, as a collective, the system serves the purpose of reinventing waste management in Cairo.
