Malawi’s ambition for every child to receive a primary school education is challenged by severe lack of resources. In many rural communities, rudimentary school buildings are dark, overcrowded and unsafe; others lack even the most basic facilities. The need for 17,000 new schools was addressed in a pro-bono project for the Clinton-Hunter Development Initiative in Africa and the Malawi Ministry of Education. Twelve prototype buildings designed in collaboration with Arup were constructed at low cost, using locally available materials to make seismically safe structures, and use no energy in operation. Providing sheltered social spaces alongside daylit and naturally ventilated classrooms, the pioneering primary schools are also focal points for the wider community.

Appropriate technology
The prototypes reimagine the conventional Malawian school blocks, balancing practical simplicity with environmental performance. The typical plan for rural classrooms – two concrete-walled rooms back to back – is reinterpreted as a pair of classroom blocks separated by an open, roofed terrace. This central space serves multiple functions: a place for informal teaching, a meeting area, and a venue for health or community programmes. At each end, broad verandahs extend the roofline to create shaded thresholds where lessons can spill outdoors and parents can gather.

The design team developed a construction system following the principles of ‘appropriate technology’ – one that is suited to local social, economic, and environmental conditions, empowering communities by promoting self-sufficiency. Each building sits on a concrete slab supported by brick spread foundations, a cost-saving method that reduces the amount of material required. Walls are made from soil-stabilised blocks, produced on site using local soil and hand presses. This approach avoids the need to transport heavy materials over poor roads and provides valuable construction training and employment for villagers. A timber roof structure, braced with slender steel ties, supports a cranked corrugated metal roof designed to bring in daylight and encourage airflow through the interior.

Durable and sustainable
As most rural schools have no access to electricity, the buildings rely entirely on passive systems for light and comfort. Sophisticated daylight and thermal modelling guided the design of window sizes and roof openings, ensuring that classrooms are bright yet protected from glare and overheating. The result is a calm, evenly lit interior that enables children to read and write without eye strain, even at midday. Cross-ventilation and shaded outdoor areas keep temperatures several degrees lower than those of conventional concrete schoolrooms.

All elements of the school buildings are simple enough to be built and repaired without specialist tools. Rainwater is collected from the metal roof, and the buildings’ orientation makes the best use of prevailing breezes and solar angles. The plan and construction system also gives the buildings a flexibility which will enhance their longevity; the typical school building has been modified in a number of cases to provide other forms of accommodation, including housing for teachers on site adjacent to a number of the classroom blocks.

The prototype Malawi schools – adopted by the Ministry of Education as a model for future development – show how thoughtful design can multiply the social value of scarce resources. Each building provides a healthy, adaptable learning environment for around 100 pupils, at the same cost as a typical rudimentary classroom: just $25,000 for each 280-square-metre school. By linking environmental design, local participation and educational ambition, the buildings make a tangible difference where it matters most.
