R/UDO improves the drainage infrastructure of an unplanned settlement in jakarta

since we first shared their ‘megacity skeleton 1‘ project, r/urban design office (R/UDO) and studio cikini have returned with the second part of their work to improve living conditions in an unplanned settlement in jakarta, indonesia. after designing an initial housing prototype to provide more natural light and ventilation, the second project involved improving the drainage infrastructure, which is one of the main issues of informal settlements.

as one in a series of prototypes, ‘megacity skeleton 2’ followed the same construction method of the first project, which combined a primary ‘permanent skeleton with a secondary ‘flexible skin’. however, this project also sought to renovate and extend the existing MCK, which is a water facility in the local community: ‘M’ = mandi (bath), ‘C’ = cudi (washing), and ‘K’ = kakus (toilet).

through the renovation and extension of the existing MCK, R/UDO and studio cikini utilized the ‘environmental void’ not only to bring ventilation and daylight into the interior but also as part of the drainage infrastructure that connects to the newly-constructed septic tank. the drainage of the surrounding houses was also connected to this septic tank so as to be easily connected to the trunk sewer which is planned to be realized in the future.

the existing building consisted of a one-story community office box and MCK. in this project, the team proposed a two-story building with community-managed rental rooms on the first floor, and designed a management scheme that uses the rent income for building construction costs and maintenance costs.

the skeleton frame was made of concrete like the first housing prototype, and the roof above it was made using a steel structure. all the columns and beams are composed of a combination of c-beams that can be transported by manual labour, allowing the structure to be easily constructed by local residents.
