The Old Woman of nursery rhyme fame who lives in a shoe could end up with a neighbor who lives in a concrete drain pipe.

OPod Tube Housing was conceived by Hong Kong-based James Law Cybertecture and is an experimental, micro-living housing unit aimed at easing Hong Kong’s affordable housing problems.

The units are built from 2.5-meter-diameter concrete water pipe, and can accommodate a 100 sq.ft. apartment for as many as two people, with space for living, cooking and a bathroom. Each house is equipped with smart phone locks for online access.

The tubes may be stacked to become a low-rise building that can be located in different sites across Hong Kong and other cities.

The firm's initial venture in tiny house concepts was the 2015 AlPod, a container-sized mobile pod house made of aluminium. It was lightweight and designed to be a prototype for a new kind of modular, mid-rise residential tower. The container offered 450 sq. ft. of living space and cost $64,000.

As part of the design, a flat floor is installed to provide an internal size floor space of 100 sq. ft., which feels more like 150 sq. ft. because the curved walls accommodate for the built-in furniture.

Law estimates the cost to buy and outfit a concrete water pipe to be around $15,300.
