A three-storey floating school will soon be used in Makoko, a poverty stricken community on the flooded coastline of Nigeria’s capital. The new primary school in the Lagos slum is built on a foundation of 256 plastic drums. Powered by solar panels on the roof, it will be able to accommodate more than 100 students.
