Hong Kong’s notoriously expensive housing makes owning an affordable home a pipe dream for many residents.

Now a local architect has proposed a novel idea to help alleviate that problem: building stylish micro-apartments inside giant concrete drainage pipes.

James Law’s OPod Tube Housing is at the conceptual stage, but it has attracted attention as an innovative if untested way to deal with housing shortages.

At 100 square feet the tube houses are not that much smaller than Hong Kong’s infamous “cubicle homes” — older apartments subdivided into cramped and squalid living spaces.

They are roomier than other types of tenement housing, such as so-called “coffin” and “cage” homes.

The idea came to Mr Law when he spotted leftover storm sewer drain pipes at a construction site.

They might be converted into “really cute micro-living architecture”, he said.

He has only built a prototype to test public interest but has already received inquiries from around the world.

There is a lot crammed into the OPod. It consists of two sections of 8ft diameter pipes fitted with glass doors on both ends.

A living area includes a bench that converts into a bed, opposite shelves on the facing, curving wall.

Another shelf fits a bar fridge and a microwave next to a galley sink beneath an air conditioner. A tiled bathroom at the end includes a combined shower and toilet.

The OPod cost 15,000 US dollars (£10,000) to build.

Mr Law said he envisions renting them out to recent graduates on low incomes trying to get a foot on the housing ladder at a fraction of the market rate.

“My dream is the OPods will be a new kind of living for young people just starting out in life,” Mr Law said.

It is less a long-term solution to Hong Kong’s housing crisis than a novel way to make use of leftover spaces where conventional housing does not fit.

The pipe homes could be stacked into gaps between buildings, under highway overpasses or on the roofs of existing buildings.

“This kind of house is really portable. We (can) actually make it in a construction site and then we lift it on to a truck and we can deliver it anywhere,” Mr Law said.

“So it represents a new, affordable architecture.”
