Water Responsive House Semarang 2050

project 1

Semarang, Indonesia | 2021 Academic, Final Project Supervised by Wahyu Setyawan, S.T., M.T.

Due to the natural land subsidence occurring since 11.000 years ago, Semarang is prone to rob flooding that reaches 10–13 cm in height every

year. By 2050, Climate Central predicts that most northern and central parts of Semarang will drown by rob flooding. Consequently, it risks the

resilience of Semarang communities in the long term, especially for the lower economic class, in retaining housing as their fundamental need due to their limited adaptive capacity. This study proposes a settlement that

can help lower-class communities corresponding to Semarang’s flood in

both short and long terms in 2050.

This study resulted in a government-owned floating co-housing settlement that enables the community to mitigate communally, considering the design’s formal, spatial, material, construction, landscape, and utility. It highlights four main concepts: low-cost floating co-housing,

detachable modular structure, social connectivity through linked pathways and public spaces, co-housing with up to 15 family members of accommodation, water entry exclusion, and sustainable drainage system. Lower-class communities will be able to rent the housing if dwelling loss occurs due to rob flooding.

For these few years, rob flooding in Semarang has amplify severe

loss to the city, infrastructure, and its community. If this keeps happening, this disaster will eventually cause permanent loss of houses and lives of many people. Semarang’s sea level is threatened to reach up to 21 cm in 2050 (ACCCRN, 2010). At that year, people will have to move to higher places or rent new housing in order to survive. With the inclining demand of housing, prices will also rise to compete the market. Here, lower class communities that are affected in rob flooding are in

concern as their low economic capabilities will be a difficulty to gain

better, decent housings for them to live.

With the concern focusing on Semarang lower class communities that are affected by rob flooding in 2050, this project will resolve the

following question, How does housing be able to support lower class communities in Semarang in adapting to rob flooding at 2050, either in a short term “ or in long term?

Social connectivity is gained through the seamless access created by the wooden bridge that connects the housing to the public building. The public building and the bridge is a static building that doesn’t adapt with the water level, while the housing and the public building deck adapts with the water level rise.

Meanwhile, public community are able to access the housing through the bridge that connects to the third level of the public building. Frame rigid structure is used to hold an equal load for the structure.
