A Nigerian engineer built his first model house with 14,800 sand-filled plastic bottles; the experiment later grew into 15 houses, including a five-bedroom duplex

Nigerian engineer Yahaya Ahmed is building homes using thousands of discarded plastic bottles. His initiative has constructed up to fifteen houses across Nigeria and beyond. This method significantly lowers construction costs and provides excellent insulation. Sand-filled bottles are incorporated into walls, creating durable and long-lasting structures. The project addresses plastic waste while offering an affordable housing solution.
