The house that Xiao built

A professor on sabbatical in China has created a prototype of a sturdy, quick-to-build bamboo house designed to help the vast number of people made homeless by the Sichuan earthquake.

Prof Yan Xiao, an expert in structural design and retrofit in the Sonny Astani Department of Civil and Environmental Engineering at the University of Southern California, has been experimenting with bamboo-based materials for highly demanding structural uses in China's Hunan province, and recently built the world's first bamboo truck bridge there, in the city of Leiyang.

He went to nearby Sichuan province the day after the Sichuan earthquake hit and then returned to the Chinese Ministry of Education Key Laboratory at Hunan University, where he immediately sett to work on a housing solution.

The prototype bamboo quake relief house he built in less than two weeks adopted a modular design that can be adjusted according to specific family needs.

'The modular units are connected by bolts and are easy to manufacture and assemble,' said Xiao. 'Four to six workers can assemble a 22.3m² house in about four hours. The majority of the structural materials used are processed bamboo veneer sheets, a kind of bamboo fibre composite.'
