The expandable house (‘rumah tambah’ in Bahasa Indonesia, or rubah for short) is designed to be one part of a sustainable response to the challenges of rapidly developing cities like Batam, in Indonesia’s Riau Archipelago. Once a collection of sleepy fishing villages of a few thousand inhabitants,Batam developed to be a cosmopolitan city of over one million people in less than 40 years. This remarkable growth, fueled by a new free trade agreement and Batam’s proximity to Singapore, has not abated. Young migrants from all over Indonesia moved there to seek their fortune.
By 2015 Batam was named the fastest growing city in the world. As a consequence, the city was confronted by major planning problems: How to accommodate the influx of migrants?
How to provide sufficient housing, and appropriate water and sewage systems?
How to fund adequate transport infrastructure, and provide schools, universities and hospitals?
The expandable house project focuses on the challenge of housing. It does so by allowing the building to be flexibly configured around the fluctuating patterns of resource consumption and expenditure, or metabolism, of its residents.
Practically this means understanding the patterns of household income generation and expenditure, water, energy and food consumption, as well as waste production. As this metabolism is usually uneven and often precarious, it is important that the architecture can be a dwelling and income generating unit, that manages its own waste, water and energy locally.
