In 2016 the nonprofit Ghanaian NKA Foundation issued a challenge to the architecture world to 'help generate modern mud housing for education to replace the rural mud house type. The basic idea is to generate durable and scalable mud-house types by drawing on the accumulated knowledge about ways of building in a tropical climate.'
Lida's and Penny's design used plastic bottles filled with compressed soil, a practice also known as the Bottle-Brick construction technique, that is 20 times more durable than traditional mud walls and bricks. Plastic tubes were incorporated to add ventilation and natural light.
Passive design strategies were incorporated to achieve maximum cross and stack ventilation, sun protection and water harvesting.
The foundation was raised 80 cm above ground to protect the classroom from erosion during the rainy season.
