However, as the cost of timber is going up and supply is limited, people are switching over to concrete, thereby abandoning a rich architectural tradition. This building is built not only for earthquake resistant structure but to preserve and promote the traditional architectural form. Constrcution
Bamboos are well known for their lightweight, flexible, strong poles that enhance the earthquake resistance of the buildings they are used to construct.The size of the final bamboo structure is 100m2, which at a cost of approximately US$140/m2 is roughly half the price of an equivalent local timber building. For the construction, all bamboo was treated using a Modified Boucherie System, which impregnated boron compound into the bamboo as a prophylactic against pests. Modified Boucherie System offers a fairly simple but effective preservation

The house is built to last, with an expected life-span of at least 20 years, and its earthquake resistance has already been proven — immediately after completion in September 2011 the house withstood shocks from an earthquake in nearby Sikkim, India, without suffering any damage.
