A new bio-based building processed by winding technology, using bamboo and straw as based material and biowaster as filler.

  It has more advantages of beautiful form, heat insulation, sound insulation, excellent wind resistance and seismic resistance, convenient installation, reasonable mechanical performance and low cost etc., compared with traditional houses.

  The bamboo winding house has broken the construction tradition of modern architecture and abolished the concept of wall, tile and beam.

  The bamboo winding house has been decorated for a single room in the factory, and even the furniture has been placed well. After the whole construction is transported to the site, several rooms can be integrated and assembled together, so that the building decoration rubbish will be left to zero. And it’s construction can avoid the noise pollution on site.

  The integral building has outstanding wind resistance and seismic resistance performance, so in the earthquake and disaster prone areas it will greatly reduce the harm of natural disasters upon mankind.

  Units square cost of bamboo winding house is only RMB 1200~2000, 50%~80% lower than wood structure houses.

1)Market capacity of rural housing

There are 180 million households in rural areas of China. If they all change their houses to bamboo winding houses in 30 years, every year 6 million households need a change. Assuming 20  ton/household ·200 m2, 120 million tons of bamboo winding houses are needed, so the annual output would be more than RMB 2 trillion.

2)Resource conservation

Rural housing replacement alone, would save 18 million tons of steel per year (China’s total annual production of crude steel is 790 million tons), 970 million tons of cement (China’s total annual production of cement is 2350 million tons), and 300 billion pieces of bricks (China’s total annual production of brick is 500 billion pieces).

3)Poverty alleviation with straw

24 million tons of straw would be used every year. Assuming every ton of braided straw is worth RMB 2500, 24 million tons of straw would be worth RMB 56 billion. If a poverty alleviation criteria of RMB 4000 is applied, 14 million farmers would be lifted out of poverty.
