Francis Kéré’s Revolutionary Slingshot Towards Architectural Sustainability
Imagine a typical day during the hot season at Gando Primary School in Burkina Faso, where a building designed by architect, Diébédo Francis Kéré, has transformed the learning experience since its completion in 2001. As the sun rises in the small, Burkinabé village of Gando, the students are arriving at Gando Primary School already feeling the heat of the region too intense to beggar our human, evolutionary ability to adapt to anything. Across the dry savanna landscape, there is dust everywhere just as the roofs of the nearby traditional buildings are becoming one with the sun. However, as the students enter their respective classes, their daily sigh of anticipation and relief is resounding: the temperature has dropped considerably enough to make even them think they are in a completely different climate; soft, natural light filters through the perforated ceiling; the zephyr moves smoothly through the classrooms, courtesy of the elevated roof design; the sound of wind also flows through the building’s ventilation gaps; and the texture of the compressed earth blocks stay cool to the touch. The students are comfortably working at their desks, and the teachers are moving between corridors without sweating. What seems to have been an almost irrepressible reality has been conditioned by sustainable architecture, headed and made possible by the innovative brilliance of Kéré.
Kéré, born on 10 April 1965, is a Burkinabé-German architect from Gando, a village in Boulgou province located 223 kilometres from Ouagadougou, the capital of Burkina Faso. In the early 1970s, at the age of seven, he had to leave his immediate family to study in the city. At the age of 20 in 1985, he travelled to Berlin, Germany on a vocational carpentry scholarship, learning how to make furniture and roofs by day while attending secondary school at night. Awarded another scholarship in 1995 to attend Technische Universität Berlin and train as an architect, Kéré graduated with an advanced degree in 2004. However, three years earlier, he had accomplished what would define him as a visionary and revolutionary architect. He created a building in collaboration with the people of his community in Gando, using local materials from clay to local woods—the now famous Gando Primary School. The project was funded through a foundation called Schulbausteine für Gando (Bricks for Gando), which he founded in 1998. As architecture curator and critic, Kate Goodwin, notes in the anthology, Sensing Spaces, this charity, ‘raises money to improve life for the people of his home village.’ The foundation was renamed Kéré Foundation in 2005, conscribing Kéré’s socio-cultural capital and image to give the charity more visibility.
For someone who comes from such extreme weather, a national reality grappling with high levels of poverty (according to Global Finance, Burkina Faso sits as the 16th poorest country in the world as of 2024), and a village with no schools, electricity, or clean drinking water, Kéré’s mission as a trained architect was simple and his question towards his revolutionary idea-turned-accomplishments even simpler: to build schools that inspire both the community and the students about the possibilities that abound in their small community as well as in the locally sourced materials they think so little of; the question was: ‘How can we use the most available material just because it is cheaply available to create something sustainable?’ As the Polish scholar and sociologist, Magdalena Matysek-Imielińska, argues in her 2024 paper, problematizing the West’s interest in African architecture and positioning Kéré as, ‘a spokesperson of African architecture:
Kéré’s architecture is modernist in the sense specified by the first German modernists… It is an instrument of social change involving the emancipation of the local population, including women and children; it also takes into account and respects the local environmental, social, and economic context.
Therefore, with every project Kéré has taken on since 2001 after the completion of Gando Primary School, Kéré has found many ways to answer that question addressing climate and social challenges of his home country through creativity as well as his determination to educate and inspire through his architecture. In ‘Beyond the West: Francis Kéré,’ his 2020 interview with the publication, gestalten, Kéré essentially states what is central to his work as an architect and visionary: ‘Inspiration is a source of development; it is a source of energy. We need vision; we need ambition. Do not fear criticism. Just go.’ His works in Africa, and across the world, convince us that he is the physiognomy of that vision and ambition, both of which he wears so well because he goes at the possibility of being able to inspire with a monomaniac energy.
THE REVOLUTION OF LOCAL MATERIALS
When Kéré came back from Berlin and started rallying his community in the early 2000s, trying to convince them of the architectural potential of those local materials that they had in abundance but failed to utilize for construction purposes, he sure had a long way to go. Regardless, one can argue that he arrived early on the architectural scene, given his apt understanding of his communities’ architectural needs. For Kéré and his community in Gando, it is not enough that potential abounds in clay and the eucalyptus trees, for instance, they also needed to see what new and improved uses to which they could put these abundant materials without compromising on quality and durability. It is also not enough that there is sound science to back it up that clay is the perfect material for the intense climate of the savanna landscape because it is rich in thermal mass—that clay, more than the cement brick boxes conventional for construction in the region, has the ability to store, absorb and release heat.
People of Gando have good reasons to think little of local materials like clay and local woods; clay, for instance, has proven, quite historically, to be seasonal and fragile: it is not resistant to rain and the buildings constructed with clay can only be enjoyed during dry seasons; wood, moreover, is susceptible to termites, making it virtually unusable for buildings in such extreme climate. Moreover, maintaining both materials is too energy-consuming and more expensive in the long term than settling for buildings constructed with conventional materials with considerably less thermal mass than clay. So, the first problem Kéré had to solve was how to improve the quality of clay and he did. In Gando Primary School (2001), his now-famous first project, Kéré devised a way to improve the local material central to his visionary architecture in clay blocks called adobe: he added up to ten per cent of the amount of clay to be used for construction in cement and mixed it to create bricks. In these earlier projects, he mixed clay, sand, cement and gravel and poured it as one would concrete to make compressed earth blocks. In addition, he got the Gando community to contribute to the construction process of the school by having them bring rocks that were available around the community to lay the foundation of the building, saving a lot of resources and energy in labour.
The most important aspect of Kéré’s innovative approach to architecture is that his primary principle of using local materials is as simple as it is broad, inclusive and flexible. For example, if clay is the material that is abundant around the location of a new project as it is in Gando and other parts of Africa, Kéré’s work as an architect is to find how to put that clay to the most durable and aesthetic use; and if the abundant materials available is something like wood, his work, championing innovation and creativity over the generic and conventional, is to devise how to best put the wood to proper use. Essentially, Kéré does not seem to depend on the materials themselves but his determination and ability to come up with solutions for each project as the problem demands, to use the available materials to inspiring effects.

Another example of the flexibility of his approach to architecture is exemplified in the project of Dano Secondary School (2007) in Burkina Faso. In this area of the region, the type of soil available in abundance is called laterite. Faced with the scepticism of the community about the durability of a material that Kéré knows and refers to as ‘a magical stone,’ the architect once again devised a method of improving the quality of the material by using a machine to cut it into bricks, which accomplishes the triad purposes of strengthening the material, making it symmetric, as well as convincing the people that clay is more than ‘a poor peoples’ construction material’ but a material with endless potential for the architectural needs of the region and of Africa at large. After cutting the material, they then dry it in the sun to harden. According to Kéré Architecture, ‘The [laterite] material provides an excellent source of thermal mass, absorbing the heavy daytime heat and radiating it at night.’ In Kéré’s architectural vocabulary, it seems, the word ‘waste’ would struggle to find an entry, and if it does eventually find an entry, it would struggle to fulfil its essence materially, and if it does fulfil its essence materially, the success would be minimal and natural in the sense of how natural materials are chipped off for qualitative transformation. Essentially, Kéré is always trying to do more with less, as he himself states during his 2020 interview with the news and programmes presenter Sohail Rahman for Al Jazeera, something we should all learn to do in our endeavours towards development in Africa.
In addition to these local clay materials, Kéré also innovates by including, along with the other locally available materials, local trees, especially the eucalyptus tree, which the local populace only uses for temporary shelter, scaffolding, and fire for cooking. For their building construction in Burkina Faso, people often import their wood from Ghana and Côte d’Ivoire, some over 1,000 kilometres away from the capital city of Ouagadougou. However, once again, Kéré found an impeccable and sustainable use for the eucalyptus trees in his project in Koudougou, Burkina Faso, the Lycée Schorge Secondary School (2016), which ‘sets a new standard for educational excellence in the region, while providing an inspiring showcase of local building materials applied to an iconic and innovative design.’ Taking inspiration from the community’s use of the trees as scaffolding, Kéré modified the usage of the trees by making them an essential part of his design and construction engineering: the eucalyptus woods are used to wrap around the entire building, ‘like a transparent fabric and creates a variety of shaded intermediary spaces between itself and the classrooms where students can gather informally to wait for their classes. In these spaces, the organic vertical elements produce a stunning play of light.’
When we compare his material choices to conventional options, the latter falls terribly short on account of energy, cost and adaptability to the intensely hot climate in many parts of Africa. There have been many reasons why Africans are sceptical about using the local materials they have for construction as mentioned earlier, each of which Kéré has squashed and barraged with his innovative and quite inventive architectural ideas. So much so that if the argument for using local materials in modern architecture is that they would not be as durable, time has proven Kéré’s architectural principles nothing less than slanted towards durability; if the argument is that clay bricks will make for less appealing buildings, from Gando to Benin, Kéré Architecture has done some of the most beautiful yet culturally resonant works of architecture in the last couple decades in Africa and the rest of the world; and if the argument is that the only reason we should give these achievements a second thought is because they are cheap, Kéré’s argument is present in his representative works: that even cheap can be revolutionary. Not only revolutionary though, but quite sustainable, too. What else does an architect have to add to make us see that our past in Africa as far as architecture is concerned is indeed a prologue of what we can achieve in the present if we pay close attention to the things our ancestors thought the world of but that we have been conditioned to think less about? Intelligence is a river; it often flows from the past: Kéré recognized the enduring value of clay, a material often overlooked in modern construction, and is now using it to build the architectural infrastructure of the future, in resonance with the culture we are letting slip out of our hands for the more fashionable though generally breathless ones.

CLIMATE-SMART DESIGN SOLUTIONS
There is no doubt that the innovation and inspiration in adapting our neglected local materials for construction instead of depending on the conventional, imported materials is immeasurable for African architecture. However, since everything concrete made by humans out of nature was once an abstract idea, Kéré’s architectural accomplishments are no exception because it is how his designs respond to environmental challenges that makes Kéré’s ideas and achievements so revered on the global stage. In a place considered one of the hottest countries in the world with the annual average temperature ranging between 25-32°C, ‘with a monthly minimum temperature of 17°C in December and January and maximum temperature of 40°C between March and April,’ according to Climate Centre, an International Federation of Red Cross and Red Crescent Societies Global Reference Centre hosted by the Netherlands Red Cross in The Hague, innovating with local materials for construction seems subsidiary to the primary problem of answering the questions that the hot reality of the region poses. Therefore, the true architectural revolution, which is an unprecedented achievement, comes from Kéré’s visionary insight in finding ways to make those local, abundantly available materials as implements of counteracting the intense climate of the place. But how does he go about this? Kéré Architecture’s philosophy reads:
Our approach is local and participatory, learning from and responding to each project’s context and placing a project’s users at the centre of the design process, in order to ask the right questions. It then draws from our legacy of creativity and resourcefulness to respond with sustainable solutions that project an afrofuturistic vision, casting off dominant norms to set our own precedents.
There is flexibility at the atrium of the studio’s approach to architecture: just as what is abundantly available around the site of the construction determines what will be the primary materials for the building construction, the climate of the region also determines the sort of design and the functionality of the aspects of the resulting building.
For instance, the intensely hot climate of Burkina Faso, imposing extreme demands even on sustainable architectural innovation, gave birth to Kéré’s signature raised or overhanging roof design. Meanwhile, as time progresses, Kéré’s approach to roofing in Gando showcases an impressive evolution in climate-responsive architecture. His original Primary School design of 2001 tackled the common problem of overheating metal roofs through an elegant solution: a raised corrugated metal roof separated from the learning space by a dry-stacked brick ceiling, creating a ventilation system where cool air entered through interior windows while hot air escaped through clay roof perforations. However, when overwhelming enrolment prompted an extension in 2006, Kéré refined this concept with a sophisticated vault system. The extension building replaced the flat brick ceiling with an arched version, topped by a corrugated metal roof that echoed this curvature with a gentler arc, ‘exposing the intricate truss work’ between them. The vault design integrated ventilation gaps that allowed hot air to rise and escape naturally, which is an opposite demonstration of how iterative, local architecture can evolve to enhance both aesthetic expression and environmental performance. This architectural progression not only preserved the core principles of natural cooling but elevated them through a more dynamic form. This project marked a significant step in Kéré’s development of sustainable building practices in the extreme climate of Burkina Faso.
In addition to his unique and evolving approach to roofing, Kéré provides an innovative approach to natural lighting. For this, he has a simple question: ‘How can we take away the heat coming from the sun, but use the light to our benefit?’ His roofing system takes care of the former while his approach to lighting in his design takes care of the latter. At the Dano Secondary School (2007), for example, Kéré introduced ‘upside-down plaster vaults reminiscent of draped fabric’ that diffuse indirect sunlight while brightening spaces without increasing the temperature. This approach reached new complexity in the Lycée Schorge (2016), where perforated plaster vaults in the ceiling work in concert with a remarkable subsidiary façade of local eucalyptus wood. This wooden screen ‘wraps the classrooms like a transparent fabric,’ resulting in an organic interplay of light and shadow in the intermediary spaces while protecting the building as well as the students from direct solar gain.
Also, in Gando Primary School Library, started in 2010, he developed a distinctive ceiling system by using locally crafted earthenware pots brought by the women of the community, cut in half, and integrated into the concrete slab. These circular openings at the top of the building create a dynamic pattern of natural light on the ground, protected from direct sun and rain by an overhanging corrugated metal roof with strategically placed polycarbonate sheets above the openings. This lighting solution is seamlessly integrated with the building’s passive ventilation system, where the hot surface of the roof induces a stack effect, drawing cool air in through the windows and out through the ceiling perforations. This integration of lighting and thermal comfort exemplifies Kéré’s approach to energy efficiency, where architectural elements serve multiple functions: providing illumination while facilitating natural ventilation, thereby eliminating the need for artificial lighting and mechanical cooling during daylight hours. Even in projects where active cooling systems are needed, Kéré makes sure they are needed only minimally. For instance, in Startup Lions Campus (2021), an information and communication technology campus in Turkana County, Kenya, the studio uses local quarry stone and stacked towers for passive cooling to minimize the air-conditioning required to protect the digital equipment, thereby reducing its greenhouse gas emissions.
In his architecture for the healthcare industry, Kéré takes his climate-smart design and innovation a notch higher, this time through the water management system, implying Kéré’s deep understanding of local climate conditions in his home country of Burkina Faso. His approach to water management is particularly evident in the Léo projects where water systems are integrated at multiple scales. At the Léo Surgical Clinic and Health Centre (2014), Kéré developed a panoramic water management system recognizing that, ‘water collection and management is extremely important for the health and welfare of the local community, as well as the environment.’ The design incorporates ‘a rainwater and greywater collection and filtration system’ for irrigation, with solar panels powering the oxygen treatment of greywater—a particularly crucial feature in a region where, ‘it only rains during three months of the year.’
This water-conscious design philosophy reaches its most refined expression in the Léo Doctors’ Housing (2018) project, where Kéré creates an integrated ecosystem of water management. The building’s corrugated metal roof is specifically sloped to direct rainfall into an onsite water reservoir for irrigation, while the landscaping features an innovative ‘cooling system of drainage ponds’ that serves several functions. These ponds are thoughtfully designed with ‘water lilies to limit evaporation, while fish eat the larvae of mosquitos [sic] and other disease-transmitting insects.’ These nonpareil water management strategies not only conserve resources but also address public health concerns through what he calls ‘an interplay of functions and provision of quality of life.’ In summary, in these buildings, particularly through these last two buildings, we see Kéré’s architecture is as much engineering and design as it is poetry with abstraction and symbolism breathing livelier energy into the already inspired buildings, particularly because they are climate-smart and solve big and pressing problems in the region.

THE FUTURE OF AFRICAN ARCHITECTURE
If Kéré’s work as an architect tells us anything about the future of African architecture, it is that the future is in each and every one of our hands as Africans. In convincing us that this is the case, he begins the conversation by being at the front of the new wave of African architects doing impressive works not only in Africa but in the world. This is easy for him not only because he wants to give back to the community that raised him as the first educated person from his small village but also because he is a bunch of men in a single body: a visionary, architect, aesthete, artist, carpenter and, ultimately, an educator.
The people of the communities where he has worked in his home country of Burkina Faso have been central to his architectural projects through their active participation, either through the women fetching water and bringing wood to the sites of construction or the youths of the community helping with labour. No doubt this community participation considerably reduces the cost of resources, and the energy spent on labour because there are always many people helping out, further accelerating the construction process without improvising on the quality and the aesthetic structure of the buildings. According to Matysek-Imielińska, ‘Architecture is not about buildings, but about the process of building—a process during which the transformation of each member of the community, of everyone building, takes place. It strengthens ties and makes people feel proud and empowered, but also teaches craftsmanship, the understanding of construction processes, and material consciousness, while also granting livelihood.’
Hence, community participation is neither central to Kéré’s architectural philosophy because it contributes handsomely to the cost-effectiveness of adapting local materials for modern buildings nor because it saves a lot of time and energy in labour. Rather, community participation is central to his work because it gives him the opportunity to sensitize the people about the potential that abounds in the materials available abundantly locally that are well-suited for modern, sustainable construction. Also, coming together as a community to work on those projects has economic consequences because through their active participation, as Matysek-Imielińska figures, they are well positioned for economic opportunities through their acquired experience. But most importantly, community participation helps Kéré himself fulfil his major goal of training the younger generation of African youths on how to make use of available materials in their localities for sustainable construction.
Kéré believes the future of African architecture is in the hands of the youths and that there is as much talent in Africa as there is anywhere else in the world. Just as much, he believes that what these African youths need to make proper and productive use of their talents is opportunity. He recognizes this condition and is addressing it through his work. For example, in the building of Gando Primary School Extension (2008), Kéré Architecture mentions explicitly how the ‘building benefits from the lessons learnt and skills acquired by community members in the construction of the Gando Primary School.’ In his 2020 interview with gestalten, Kéré claims that he wants to build inspiration. Though abstract and evidently difficult, he is nonetheless accomplishing his goal not only by constructing buildings that resonate with and inspire people in Africa and around the world but also by building younger people along the way—by showing them there are possibilities in places even as financially poor and generally resource-scarce as Burkina Faso⎈
