Yahaya Ahmed, a Nigerian engineer, made a house in Kaduna utilising 14,800 sand-filled plastic bottles as bricks.
Premium Times reports that Ahmed is the director of a non-governmental organisation, Developmental Association of Renewable Energies in Nigeria (DARE).
The engineer said the house was made by his organisation to promote recycling of waste materials, create jobs and ensure a more protected environment in Nigeria.
Describing the process of building the house, Ahmed said workers loaded the plastic bottles with sand and linked them at the neck by an intricate network of strings.
He said the building is the first of its kind in sub-Saharan Africa, adding that it is more economical to build because the building materials are available on the streets and trash dump centres.
The house has three rooms, a toilet and a kitchen.
In terms of strength and durability, Ahmed said the house is “20 times stronger than brick walls houses and can last for over 300 years if constructed properly and carefully.”
According to him, the building is fireproof, bulletproof, earthquake-resistant and can adapt to all kinds of climate changes.
Ahmed said anyone with masonry skills can be used as labour in the construction of one building, adding that his organisation has trained many youths.
