The expandable house combines a conventional steel-reinforced concrete frame with an aerated concrete block cladding and an innovative composite bamboo cladding:
Tailored to and learning from the rapidly expanding peri-urban fringes of Asian cities like Batam – the world’s fastest-growing in 2015 – this new sustainable dwelling type is designed to be flexibly configured around its residents’ often precarious resources over time.
Locally made retractable bamboo screens are used for rain screens, shading and privacy:
Its steel-reinforced concrete frame has aerated concrete block cladding at ground and composite bamboo cladding or retractable bamboo screens above.
Hydroponic cultivation of leafy greens in the companion vertical kitchen garden (or kebun susun):
It is based around the following five principles:
(1) Sandwich section: the roof can be hoisted to add levels – the foundations can support up to three floors.
(2) Domestic density: the house encourages densification at domestic and neighbourhood scales.
(3) Decentralised systems: rainwater harvesting, solar panels, septic tanks and passive cooling principles are integrated.
(4) Productive landscapes: a vertical kitchen garden and bamboo nursery are included.
(5) Seed package: the technology, resource strategies and design guidelines can be developed in different ways depending on local social, cultural and environmental conditions.

The project supplements the dynamic logics of auto-construction endemic to rapid urbanisation in peri-urban regions:
