the international architecture biennale rotterdam (IABR) 2009, in collaboration with ikatan arsitek indonesia (indonesian institute of architects jakarta chapter), has announced the winners of the ‘gotong royong city’ competition, which asked for individuals to submit ideas on envisioning the future of jakarta, indonesia.

the first place winner is ‘jakarta bersih!’. jakarta struggles with issues of overpopulation, pollution, shortage of green area, poverty, floods and vast waste-volume. ‘jakarta bersih!’ is a vertical cleaning kampung (a very condensed community) consisting of a two-sided high-rise building on top of a waste processing machine. relocating the kampungs to buildings will create space for green open areas, improving quality of life. waste processing also provides jobs and income for those who are struggling financially.

‘field estate’ is a platform for symbiotic urbanism. the third place winner is an urban development game. the aim is to achieve a city-scape of typological diversity and cooperative coexistence, combining normally segregated urban conditions into strategic partners. the game is played with two components: towers and platforms which move interdependently, their formation mimicking a water lily. the purpose of the towers is to provide density. the platforms are meant to adapt to the existing infrastructure; their employment following the logic of community and preservation. a bio-textile semi-transparent roof absorbs and recycles water, then dehumidifies, cools and cleans the air.

a project which received honorable mention was ‘stitching the strip’ which makes reference to the jalan sudirman in jakarta, which is an example of a modern corporate strip. a metaphoric symbol for ‘stitching the cut’ between the existing urban structure of jakarta, its purpose is to reconnect kampungs by a series of bridges and reorganize the space around skyscrapers.

‘ojek city’ is a nest – an organic shelter that can be built everywhere and can function as a temporary place for the community. it can fill lost spaces turning them into social spaces, easily maintained by and belonging to the community.
