WHY BAMBOO FOR HOUSING? Growth rate is three times faster
than eucalyptus and it conserves water
High annual yields of about 17 tons per acre in a well managed plantation
Bamboo matures in 4-7 years compared to other trees that take over 15 years
Due to its lightweight, high elasticity and great resistance to rapture, bamboo is ideal for numerous construction uses
It is cheaper than steel and concrete
When well treated, it is durable upto 50 years

The two types of houses employed different construction techniques:

ENGINEERED BAMBOO HOUSE - MASENO
Engineere bamboo is a bamboo product designed to function as timber
This was mainly imported from China
The construction process comprised a bamboo framed structure which was then plastered and painted
The verandah was polished to promote durability

NON- ENGINEERED BAMBOO HOUSE- MASENO
In this house, bamboo from Kakamega Forest was used
Mature bamboo culms of between 3-5 years were selected for harvesting since they had low amounts of starch
A total of 10 youths were recruited as construction workers from the Kisumu slum areas and were trained by two bamboo housing experts

The selection and harvesting process

The bamboo culms were harvested and treated within the forest using a Boron – Borax solution
Treatment of bamboo culms is essential in order to reduce attack from biological agents e.g. insects
Preservation of bamboo was achieved using a 5% Borax solution, which was pH neutral.
The pH neutral solution was made using equal amounts of Boric Acid (2.5%) and Borax Oxide (2.5%), both in powder form, and dissolving them in warm water.

Bamboo is as durable as any other construction material such as timber, for as long as it’s weaknesses are considered during the design process.
More demo houses, this is the only way to demystify bamboo- train more people
Address policy gaps
