Wow beautiful location, beautiful materials, beautiful house, beautifully built !You guys are blessed with huge bamboo species that grow in such a neat way and they're straight.If only we didn’t consider bamboo invasive; Rather consider it an incredibly regenerative renewable resource that we can use every day in construction and heating.Very good job, In North East India they use bamboo curtain and plaited bamboo from split bamboo sheens that can be used for the walls. Almost 30% of material can be saved. Moreover so many pins and bolts usage can also be minimized. The lower deck looks over re-inforced. The spacing can be increased leading to lesser material usage.
