The bricks are made using sack cut from a long roll into individual bags and filled with local earth, clay and just a little cement to bind the mix.
Originally designed to build shelters on the moon, Leila says that the bricks are easy to transport and fill on site.
They are also the ideal building material for the hot climate because the earth and clay mix soaks up the cold air at night and deflects the heat during the day, keeping the classrooms cool as well as being resistant to rain.
