OPod Tube House is an experimental, low cost, micro-living housing unit to ease Hong Kong’s affordable housing problems. Constructed out of low-cost and readily available 2.5m diameter concrete water pipe, the design ultilises the strong concrete structure to house a micro-living apartment for one/two people. OPod Tube Houses can be stacked to become a low rise building and a modular community in a short time, and can also be relocated to different sites in the city.
