A Hong Kong architect has invented what he believed to be the solution of overcrowded cities by turning concrete water pipes into tiny homes.

The OPod Tube Housing system aims to re-purpose concrete tubes measuring just over eight feet in diameter, and turn them into 'micro-homes' with 100 square feet of living space.

It is the brainchild of architect James Law of James Law Cybertecture who designed the build as a possible solution to the lack of both space and affordable housing in Hong Kong.

Step into my pod: The OPods are created out of re-purposed concrete water pipes that measure a little over eight feet in diameter and are turned into homes for one to two people

Snug and affordable: The 'main room' of the OPod is a front room with a sofa that can be converted into a bed at night

Pod up: This prototype show the two parts of the pods, the front room/bedroom, and another with strange and a bathroom

With a population of 6,690 people per square kilometer in 2014, Hong Kong has one of the most competitive real estate markets in the world.

The tubes are designed to accommodate one or two people and are equipped with the standard amenities, including a living room with a bench that converts into a bed, a mini-fridge, a bathroom, a shower and plenty of storage space for clothes and personal items.

According to Mr Law, the inspiration behind the tiny tube homes is practical, both for young people looking for homes as well as city governments trying to provide affordable options.

Solving problems: The OPods are designed to be stacked on top of each other in order to create small communities

A pipe dream? While the pods are still at a prototype stage, they are estimated to cost £10,885 once they become reality

Saving space: In a city like Hong Kong which is extremely overcrowded, the OPod inventors claim can solve this issue

Although the structures are far from being lightweight at 22 tons a-piece, they require little in terms of installation and can be easily secured to one another, which reduces installation costs.

James Law Cybertecture envisions the OPod being installed in urban areas unsuitable for standard construction, such as narrow alleyways between buildings, for example. Multiple units could be stacked atop each other, with simple metal stairways providing access.

The pods are still at a prototype stage, but The South China Morning Post reported that if the plans come to fruition, each OPod will cost around $15,000 (£10,885).
