Project description by jury
Jakarta’s communities who live along the river have never been equipped with proper sanitation facilities, entailing a series of impacts on both the ecosystem and people’s health. The design proposed by this project reconciles the ecosystem of the river with the local community through an affordable, culturally aware and environmentally attentive solution. The idea is to revitalize existing vernacular structures, embedding sanitary features with an optimized plant-based filtration system. Floating platforms made of bamboo and wood are placed along the waterway in a diverse array of functions: a roofed space hosts a toilet and a washing area for the residents, water is provided through rainwater tanks, a coral allows for catfish breeding while several containers are used for hyacinth cultivation, essential to filter lead, mercury, strontium and other carcinogenic compounds found in the river. A deck that connects the edge of the river to the platform acts as a trash collector. A major asset of the project is to propose an easily replicable system so that environmental benefits can grow incrementally until the benefit at the scale of a city or territory becomes tangible.
The LafargeHolcim Awards jury Asia Pacific acknowledged the project’s endeavor to highlight the urgency in finding solutions for the urban poor in South East Asia. The project was found simple yet effective and well-contextualized. The proposed solution upgrades a vernacular typology to make it more functional and environmentally sound: a modest gesture that once implemented and multiplied across a larger scale can provide a remarkable impact on the environment and on people’s quality of life.
Wellness: in between top-down and bottom-up approach
The government considers the river as a risk and therefore opts to close the river with high walls or prefer to move all the settlements that are adjacent to the river. But this solution is unsuccessful since it’s never easy to move all the housing away from the rivers and it will be ineffective if the rivers remain polluted and choked with rubbish. On the other hand, the residents along the riverbank adapt to these conditions. What is really surprising is while people who live far from the river tend to see the river as a dirty place and threat of flooding, people living near it tend to see the rivers as a habitat for living. The re-adaption is the pilot project to reconnect community, culture, and nature.
Embeddedness: Re-adaption means improving the existing vernacular
Local housing is very humble and removed from the modern world. It’s a vernacular treasure that we always neglect. The people create a facility for their activities inside the river from a very reusable and rich material – bamboo. They already have their own flexibility space programming, and they already declare their way of living. The idea of the project is to revamp the existing vernacular structure, embedding improved features that meet sanitary standards. We are designing the natural filtration system for clean water supply. The existing architecture symbolism the attachment of them as an integral part of the river ecosystem.
Advocacy: Hygiene is an important aspect for community health
Hygiene is an important standard for everyone, including people living near the river. The sustainable principle implies to advocate a greater understanding of the importance of hygiene, without separating them with their genuine behavior and culture. The proposal includes catfish breeding and the water hyacinth box to neutralize the toxins in the river. This project is intended to revamp the river communities in the Jakarta metropolis, cultivating the mindset that seeing the river as the center of various living activities. We hope that someday the river will be the source of inspiration and delicacy, not the emblem of disastrous floods and diseases. It starts with small and measured scales, focusing on the value of participation to enhance the efficacy and communication among stakeholders.See more
The districts in Jakarta that lie directly on the Cilliwing River have no sanitary infrastructure to speak of. This leads to untold problems for people and nature. Rionaldi Gunari, Nicholas Rodriques, and Gani Wiratama,students of Parahyangan Catholic University in Bandung, Indonesia, propose upgrading one of these districts using an environmentally responsible approach. “The community has made the river the center of their lives,” explains Co-author Rionaldi Gunari, “so our approach is not to take them away from the river but to allow them to use the river even more with our environmentally and socially adaptive architecture.” Existing structures are to be renovated and upgraded with the addition of new elements. Floating platforms made of bamboo and wood are designed to treat wastewater with a plant-based filtration system. Public toilet facilities are also provided. Rainwater is harvested and stored in tanks for use. Water hyacinths extract pollutants such as lead and mercury from the river. The project is simple but effective, says the jury. The solution is environmentally sustainable and functional. “The project is innovative and gently scalable,” says Marilyne Andersen. “On a larger scale, it could really have an impact on the river and its inhabitants.”Read more »

Our website search engine covers the web pages including project descriptions and expert profiles, PDFs, images and videos on the Holcim Foundation website. To improve your search results, here are some tips:
Our search defaults to term-pairing AND. If you search sustainable construction - then the search engine will look for any items containing sustainable AND construction
photovoltaic OR solar
Looks for either word
(clay OR mud) AND (school OR university)
Combine alternative terms for more specific searching
Excludes a term from results, automatically ANDs other terms listed
Use quotation marks to search for a specific phrase or combination
Asterisk (*) matches any word or phrase - so archit* will find architect, architecture, architectural as well as architrave
