Lebanese architect Leila Meroui is using a technology devised to build housing on the moon's surface to build sustainable schools in the Senegalese village of Tifuan Boleh.
The bricks are made using a bag cut from a long roll into individual bags and filled with local earth, clay and a bit of cement to bond the mixture.
Layla's method was originally designed to build shelters on the moon's surface, and she says the bricks are easy to transport and manufacture on site.
It is also the ideal building material for hot climates because the mix of earth and mud absorbs the cold air at night and reduces the heat during the day, keeping the classrooms cool as well as being rainproof.
