Bamboo Kitchen
Happy New Year to everyone.
May this be the year of bamboo and mud. Our cantina is in its final stage. The trusses are complete. The structure is about 120 sq. meters in area. It uses locally harvested, locally treated and constructed using local labor. Its a nice example of our motto “think global, act local” It is built in a remote village called Harsar in the southern plains of Nepal. According to our calculation, the structure costs more than half compared to concrete and steel. Moreover, the structure has become pride of this impoverished but ambitious little village.

Chuli Building
The more we work with bamboo, more confident we become on the strength and beauty of this vegetal steel. It makes one wonder, why isn’t this material used more in the modern construction, as there is nothing it cant do that steel would. Yet, its cheaper, available, beautiful and yet many times more ecological. Here is one of our offices that is under construction. The cost of construction is about $200 per truss, the span is five meters and total area is about 40 sq. meter. Its a combination of earth (compressed earth blocks) and bamboo. The amount of cement used is is less than 10 percent.

Truss Fabrication
One of the main reasons for disuse of bamboo in modern construction is due to a lack of skilled human resources. For better or worse bamboo can not be standardized. Bamboo comes in different shapes and sizes which makes it a very difficult material to work with. Bamboos are very hard to produce in an industrial scale. But we take that as a blessing. Sustainability, we believe, also means scale. It is very difficult to make things sustainable and yet cater to a highly industrialized and consumerist lifestyle. Anyways, to work with bamboo requires lots of patience, creativity, improvisation and obviously skills. One has to treat every bamboo as an individual, as they look and behave differently. With a little bit of encouragement, bamboo can challenge any material. With our primitive tools, we are here fabricating bamboo trusses (10 meters), that are strong, durable and perhaps more elegant than steel.

Bamboo Pavilion
Bamboo at work. In the the village of Harsar, where bamboo has been used for ages, this demonstration does indeed come as a revelation. The word “truss” is entering the local vocabularly, and indeed the local sceptics of bamboo are thinking twice. The local carpenters are lining up to learn the new techniques.

Thatchted Roof

Here is an example of a thatched roof from Japan. Thatched roof tradition is a somewhat in danger of getting lost because it requires very intricate skills to install. However, properly put thatched roof can last for more then 30 years. The advantages of thatched roof include very good insulation, available local resources, natural beauty and cost effectiveness. The disadvantages include high skills. If not properly installed it can invite mice and bird problems and require high maintenance.

Bamboo Temporary Shelter
Here is an example of a temporary shelter built by Abari in Janakpur Nepal. It is built as a storage place for all the bamboo that we have treated for the construction. It was designed in order to resist dampness and provide enough air circulation to store and dry the bamboo.
