Using a bottom-up approach, the Floating City Apps Foundation, aims to upgrade waterfront slums with small scale instant solutions. Comparable to adjusting a smart phone with apps according to changing needs, the infrastructure in a slum can be adjusted by adding functions with City Apps.
These apps are floating developments built using a standard sea-freight container, the container is assembled in the Netherlands and shipped to the wet-slum where it is placed on a locally constructed floating foundation. Because of their flexibility and small size they are suitable for installing and upgrading facilities for sanitation, housing, communication etc. They can be added to a slum using the available space on water.
