The essence of need based development relates to resources, the environment, and sustainability. The Bruntland Commission report defined sustainable development as “meeting the needs of the present generation without compromising the ability of future generations to meet their needs.”

Global warming and climate change are the result of rapid urbanization and the over exploitation of natural resources by many developed countries. There was a time in Nepal when we could proudly exclaim “Hariyo Ban Nepal Ko Dhan”(Nepal’s Green Forests are it’s wealth)but sadly, today we cannot make that claim because our Nepal forests are being depleted at the rate of 1.7% per year. We also have to learn to meet our developmental needs while protecting the environment. One way to do this is by promoting renewable resources such as bamboo, particularly in the housing sector.

Bamboo is a versatile, strong, renewable and environmentally friendly material. It is a member of the grass family, “Gramineae”,

and is the fastest growing woody plant on earth. It is called by different names in various regions of the world; “Wood of the poor” in India, “Friend of the people” in China and “Brother” in Vietnam. Now it has been termed the “Green gold” of the 21st century. Bamboo grows from sea-level up to altitudes of 3800m. Most bamboo species can survive temperature ranges from -28°C to +50°C. It grows quickly and easily, and can be sustainably harvested every 3 to 5 years.Bamboo has played an important role throughout human history and is still widely used by the rural poor. It has been extensively used for household utensils,fencing material, fuel, handicrafts, house building, scaffolding, tube well piping, food, and the list goes on. Apart from traditional uses, bamboo can also provide three strategic social and economic roles: environmental sustainability, livelihood security, and income generation.

Present Scenario of Bam-boo Resources

There are about 75 genera and 1250 species of bamboo found around the world. Southeast Asia is considered the home of bamboo even though the largest groves in the world are in South America. Nearly 150 species grow on the Indian subcontinent and India alone has

Building Bamboo Pre-Fabricated House: Background


100 species. Bamboo groves in India make up 13% of the total forest area. In Nepal there are 61 species of bamboo under 17 genera. 73 of the 75 districts in Nepal are known to have one or more species of bamboo. Due to the humid climate, eastern Nepal has more biodiversity than western Nepal. According to the Department of Forest Research and Survey, there is an estimated total growing stock of bamboo in Nepal of approximately15 million cubic meters with an approximate biomass value of 1060 M. tons.

The total coverage area of bamboo is 63,000ha, 60% of which is in natural forests. The annual production of bamboo culms is 3.01 million, 2.64 million being domestically consumed and 0.64 million exported to India. On average, each household consumes about 46 stems per year. An estimated 102 M. tons of bamboo shoots are produced and consumed in Nepal annually. It is estimated that there are around 81 processors and 509 trading firms working with bamboo in Nepal, directly employing over 1500 people.

HFHI-Nepal’s promotion of bamboo as an environ-mentally friendly con-struction material

Habitat for Humanity International-Nepal has been intentional in incorporating sustainable building technology into their projects. This has created public awareness and has been a strong advocate for the use of locally available and environmentally friendly construction materials. Bamboo is one of the oldest materials used in the construction of houses and other structures. It is strong, flexible and versatile; therefore a most appropriate raw material for almost every house building component. Habitat house owners are encouraged to use bamboo in their house construction.

Bamboo can be used for purlines, rafters, pillars and walls. Walls made of woven bamboo strips and cement plaster are becoming popular in the eastern region of the country. More than 70% of the families served by Habitat have built their houses with bamboo. Approximately 70 bamboo culms are required to construct a 330 square foot house and 80 culms are required for a prefabricated house.

Habitat is establishing a bamboo based enterprise in Jhapa , in the Eastern Region of

Nepal in partnership with “Sahara Nepal” to produce Corrugated Bamboo Roofing Sheets (CBRS). This project has been funded by the Canadian International Development Agency (CIDA) and Habitat for Humanity Canada. CBRS are not only environmentally friendly but also provide a healthy environment for the house occupants.

Additionally this enterprise is providing employment to the “Village Banks”, “Save and Build” groups, “Microfinance” groups and local farmers who cultivate and harvest the bamboo and weave the mats. One CBRS requires 4 mats and an expected 256 sheets per day will be produced during peak production levels consuming an estimated 479,232 culms.

ConclusionChristian philosopher Francis Bacon

once said, “We can only command nature by obeying her”. The natural environment has given us everything but we have to take responsibility to use our natural resources in a wise and sustainable .

We Our responsibility is to use natural resources in a sustainable manner without disturbing the ecological balance. Irresponsible environmental practices have created serious damage to our natural environment. The housing needs of an ever increasing population, both urban and rural, have brought intense pressure on our natural resources, particularly in the forestry sector.. One way that we can maintain a natural balance is by using renewable resources which in turn help reduce consumption and promote regeneration.

Additionally we have large tracts of wasteland, damaged riverbanks and degraded land that need immediate rehabilitation. In this context, trees require 25 years to mature but bamboo matures within three years. Cultivation of bamboo therefore, can be more effective in restoring wasteland and will provide for household use and bamboo based enterprises.

Many people can engage in the growing, trading, harvesting and processing of bamboo that will support and improve the lives of poor people. Nepal has been chosen for carbon business that can be promoted by commercial bamboo plantations because bamboo can sequester 12 tons carbon per hectare which is more compared to timber.


Preparation for Building a Bamboo Pre-Fabricated HouseRequired Tools and Equipment

� Drill � Grinder � Drill bits of various sizes � Local knife � Local bamboo/wooden mallet � Electrical equipment (extension cords, AC/

DC converter/voltage converter, generator for backup)

� Hand saw/Hacksaw � Ladder and scaffolding � Concrete mixer/Container (for mixing

plaster mortar) � Adjustable wrench � Screw drivers � Wood chisel � Shovel � Tray � Trowel � Plunger � Rope/String � Carpenter pencil � Bucket � Local broom � Brushes/roller brushes/varnish brush � Marker/chalk/marker lines � Sand paper � Cotton cloths


Materials List � Different sizes of bamboo (for vertical and

horizontal posts, rafters, purlines (roof beams), ridge, eaves, vertical strips, weaving strips)

� Bamboo nails � Wooden adhesive glue � Knots/bolts/P-hooks � GI tin sheet � Doors/windows frames and shutters � Bamboo woven mat for ceiling � Stone/brick � Cement � Sand � Aggregate � Paint– varnish/white cement/emulsion/

primer/enamel

Preparation of Bamboo Frames

� Bamboo collection/supply � Bamboo storage

� Bamboo cut/size as per requirement• Horizontal bamboo pieces• Vertical bamboo pieces• Vertical strip cutting• Weaving strip cutting

� Bamboo Treatment• Drill each nod of bamboo.• Immerse bamboo in solution of boric

acid and borax for 24 hours.

� Round hole cutting in bamboo based on house design.

� Packing, leveling and delivery.

Process of Assembling of Bamboo Pre-Fabricated HouseAssemble Frames (start with any one side frame)

� Lay vertical bamboo flat on the ground to enable the insertion of the horizontal


bamboo. � Insert horizontal bamboo in- between

vertical bamboo through the pre-drilled holes

� Measure and fix frame as per design � Measure diagonals to check the right angle

of the corners of the frame. (Diagonals should be equal. If both diagonals are not equal , adjust by pushing the corner of longer diagonal) Drill the junction parts and insert bamboo nails adding wooden adhesive glue on the joints.. This will fix the frame permanently at the junctions.

� Drilling holes in all the horizontal bamboo pieces should be done very carefully and precisely. First take into consideration the two consecutive vertical posts which are connected through the horizontal bamboo. Mark points on all horizontal bamboo at 2 inches distance from each vertical post. Measure in-between the two consecutive holes and divide it into three equal halves and mark the points.• Drill every marked hole in all the

horizontal bamboo. These holes are for inserting the vertical strips. The size of the hole should be to the width of the vertical strips.

• Insert Vertical strips through the holes of every row of horizontal bamboo

starting from the top of the frame. (Use Local bamboo/wooden mallet as a hammer from the top if the vertical strip do not pass easily through the holes.)

• After inserting all vertical strips through the holes, the frame is complete.

• Repeat same process for assembling all frames.

Foundation

� Layout foundation according to the size of the house.

� Excavation of the trench (as per design.) � Raise foundation stone/ brick wall up to

minimum 12 inches from the ground level. Level the top surface of foundation wall before erecting assembled bamboo frame. (Should leave space in the foundation wall to insert and concrete vertical bamboo posts which act as columns/pillars.)

Setting up assembled bamboo frames on foundation

� Erect all the frames and tighten temporarily. (Tighten by using ropes/


G clamp). ensure that all bamboo frames are properly placed as per design.

� Level and check all frames for the straightness of the structure.

� Drill and fix permanently with nuts and bolts.

Roofing structure/frames

� Lay bamboo ridge and eves and fix with P-hook.

� Lay rafters and fix with knots and bolts. � Lay Purlines and fix with knots and bolts.

Flooring

� Filling soil � Compaction of soil � Stone/bricks soling � Mix cement, sand and aggregate with water

to prepare a mortar for floor. (mixture should be in ration of 1:2:4)

� Pour the mixture above the stone/soil floor and smooth with a plunger. (casting should be 2 inches thick)

� Do thin plastering and cement punning above the concrete floor.

Weaving strips for the wall

� Weave horizontal and vertical strips for the wall. Make sure that the length of weaving strips is sufficient to weave between two vertical bamboo posts. (If the length of the strip is longer than the required size, cut down to correct length. Eliminate strips that are too short.)

Place pre-woven bamboo mat as the ceiling over the verandah space.

Door and window fixing

� Fix Frame by using nuts and bolts. � Fix Panel on frame with hinges.

Roofing

� Lay Corrugated GI Tin sheet over the purline.

� Drill and fix with nuts & bolts. (Drill holes of correct diameter and bolt on securely)

� After fixing GI sheets place, ridge cap to cover ridge space.

� Paint the ridge cap.

Plaster walls with cement and sand mortar

� Spray walls with a cement slurry using a brush or local broom before plastering.

� Mix Cement and Sand in 1:4 proportions in a container.

� Mix with a shovel adding water and mix well Make sure not to add too much water,- mixture should look dry. Soggy mortar is difficult to apply to a bamboo wall.

� Apply mixed cement sand mortar on wall using a trowel. (Plaster mortar slowly—don’t worry about excess mortar falling.) Better not to plaster both sides of the wall at the same time.

� Smooth plaster using trowel/plunger.

Gap filling (gap between two vertical bamboo)

� Insert bamboo strips in gap and fix properly. (Spray if needed)

Coloring

� Wall Paint• Paint the first coat of white cement on

plastered wall using paint brush, (mix white cement powder with water in a bucket to make thick solution - follow the directions given on the packet/container.)

• Paint final coat on the second day. (Emulsion/Distemper color) Follow the instruction of the color product - paint the wall bottom two rows in Blue and the remaining Green (Unless otherwise specified).

� Bamboo Paint• Rub the bamboo with sandpaper.• Clean rubbed surface with a cotton

cloth.• Apply/Paint weather proof varnish

carefully using brush. � Door /window• Rub frame and panel with sandpaper.• Clean rubbed surface with a cotton

cloth.• Apply primer as first coat.• Apply enamel as final coat.
