Bamboo housing design accessible for the middle class in the Philippines

12 Jan 2022

A social enterprise in the Philippines is building bamboo houses that are appealing to the middle class.

Kawayan Collective, a bamboo social enterprise initially launched in partnership with the non-governmental organisation Base Bahay Foundation, is introducing an affordable new bamboo housing design in the Philippines, that with a crew of 10 people can be built in just eight months.

The construction of the house uses a traditional building technique known in the Philippines as ‘tabique pampango’ or more widely known as wattle and dau or bahareque. The technique was used in the Philippines, and other countries in Latin America, during the Spanish colonial period. Bamboo and timber, and a plaster (a mixture of mortar, seashells, gravel, clay and other materials) were combined to form walls for churches and other buildings of the time. Examples of bamboo buildings that deploy this technique have stood for over 200 years, withstanding large earthquakes, paving the way for bamboo being recognised in the building code of countries in South America.

This cement-bamboo-frame house is a 130m2 loft with two bedrooms on the ground floor. Bamboo features as the primary structural support, and including the interior and exterior finishes the house is 80% bamboo. A large, insulated roof and screened windows allow for good airflow and minimize the need for air conditioning or daytime lighting, and the design is beautifully crafted to celebrate the traditional forms of the Philippines’s Architecture. The house costs PHP 2.5 million (roughly USD 50,000).

Nowadays, Base Bahay Foundation, with its mission to improve socialized housing with treated bamboo, is leading the use of the ‘tabique pampango’ technique in the country under the name cement-bamboo-frame. The houses using this technique have withstood major typhoons with winds of 220 km/h, making them safer but also cheaper, they are 20% cheaper than the concrete hollow block and steel equivalents.

These types of bamboo houses help to create sustainable cities and communities, not only for the house dwellers but also for the supplier of the bamboo: the farmers, cutters and processors who can build a livelihood from a previously undervalued local resource. Not to mention the climate change mitigation while using the world’s fastest-growing grass that captures carbon.

“In our design, bamboo is no longer confined to a ‘poor man’s timber’ or high-end tropical resort”

Kawayan Collective facilities in Dauin, Negros Oriental also processes over 300 bamboo poles a week into construction-grade treated poles, engineered bamboo panels and houseware products.
