The very first PERI school in Kenya opened its doors at the end of February 2024 for over 200 children. In Kibera, the largest slum in Nairobi, the first school in the PERI sustainability initiative “Building Sustainability” was built in less than a year. In collaboration with the social enterprise “Start Somewhere”, PERI developed what are known as TwistBlock Moulds for hollow concrete blocks, which were designed specifically for use in slums due to the simple and flexible manner in which they can be used. The new school building has created not only learning spaces, but also new local job opportunities.
