The amphibious house is just one solution to the ravages of climate change in low-lying coastal cities.

Nestled among hundreds of identical white and brown two-storey homes crammed in this neighbourhood for factory workers is a house with a trick - one not immediately apparent.

Hidden under the house and its wrap-around porch are steel pontoons filled with styrofoam. These can lift the structure three metres off the ground if Ban Seng village, two hours north of Bangkok, floods as it did in 2011 when two-thirds of the country was inundated, affecting a fifth of its 67 million people.

The 2.8 million baht (HK$667,145) amphibious house is one way architects, developers and governments around the world are brainstorming solutions as climate change brews storms, floods and rising sea levels that threaten communities in low-lying coastal cities.

"We can try to build walls to keep the water out, but that might not be a sustainable permanent solution," says architect Chuta Sinthuphan of Site-Specific, the firm that designed and built the house for Thailand's National Housing Authority (NHA).

"It's better not to fight nature, but to work with nature, and amphibious architecture is one answer, says Chuta, who is organising the first international conference on amphibious architecture in the Thai capital in late August.

In Thailand, as across the region, more and more construction projects are returning to using traditional structures to deal with floods, such as stilts and buildings on barges or rafts. The amphibious house, built over a man-made hole that can be flooded, was completed and tested in September 2013. The home rose 85cm as the dugout space under the house was filled with water.
