TwistBlocks Moulds
Local people can produce Twistblock moulds in local workshops – this creates jobs and boosts value creation within their community.
The Focus Areas of Our Social Engagement
Strengthening Education
Together with our partners, we support school construction and education, primarily in the Global South, to create opportunities for children and young people and help build a better future.
Strengthening Communities
By supporting non-profit initiatives in the areas of local aid, nature, culture, sports, science and education, we help build strong and thriving communities around our locations worldwide.
Making a Personal Contribution
Our employees contribute their time, knowledge and commitment to social and environmental projects, helping to drive positive change in their communities.
Our School and Education Projects
By building and developing schools, we help create better opportunities for children and young people, particularly in the Global South.
We focus on long-term partnerships and sustainable structures. When new facilities are built, school operators primarily use the TwistBlock formwork system co-developed by PERI.
School in Kibera (Nairobi, Kenya)
The first school supported by PERI was built in 2024 in Kibera, one of East Africa’s largest low-income urban communities on the outskirts of Nairobi. The Global One Foundation constructed a three-storey primary school building using locally produced TwistBlocks.
The ground floor houses the teachers room, kitchen and restrooms. The upper floors feature eight classrooms, each accommodating up to 40 children, as well as washrooms. The rooftop serves as a play area, as there is very little open space for children to play in the densely populated community.
The school is run by the Global One Foundation. Since 2012, the foundation has been supporting disadvantaged communities in Africa through a holistic approach, providing education, healthcare, daily meals and access to clean water. It currently operates three schools serving 700 children.
More than 200,000 people live in Kibera under challenging conditions, often without reliable access to electricity, water or sanitation.

Elementary School with Boarding Facilities in Syangeni (Kitui, Kenya)
Together with the PATRIZIA Foundation and Welthungerhilfe, we expanded the PATRIZIA School in Syangeni in 2025, a village in Kenya’s Kitui region near Tsavo National Park. As one of the country’s poorest regions, Kitui is affected by frequent droughts and limited economic opportunities. Education therefore plays a vital role in opening up better prospects for the future.
The new buildings were constructed using TwistBlocks. The hollow blocks were produced by independent manufacturers using reusable TwistBlock Moulds developed by PERI.
As demand for education continued to grow, the existing school had reached its capacity. The expansion included:
- Dormitories for 50 boys and 50 girls
- Six teachers’ houses
- A new “Future Room” for digital learning and vocational education
- Sustainable infrastructure including solar power, a water tank and garden irrigation

Opportunities Beyond the Classroom – Through Innovative Construction
The PERI co-developed TwistBlock Moulds are used for the construction of most of the supported projects. They enable efficient and resource-conscious construction while also promoting local value creation. The production of building components by independent local manufacturers creates jobs, builds expertise and opens up new income opportunities. As a result, not only do children and young people benefit from better learning conditions, but families and entire communities also gain long-term development opportunities.
