In Dogon country, boulders are like dusty play blocks scattered
over an immense scale. Even the baobab fails to give us a sense
of place or proportion. It is hard to imagine how one enormous
tree has witnessed millennia of human industry and survival.
The vast Bandiagara escarpment stretching 150 kilometres in a
diagonal cut across Southern Mali does little to comfort us under
the unfathomable works of nature. Relief comes from high above:
sandstone cliffs reaching as high as 500 metres are punctured
with round structures built with mud and stone. They, too, would
be scaleless were it not for the windows cut out at shoulder height
to let light in and frame a view of the outside.
Last January, I accompanied the architect Diébédo Francis Kéré and a few colleagues to Dogon country, near the border with Kéré's native Burkina Faso. We met up in Mopti to discuss two recent projects commissioned by the Aga Khan Trust for Culture to mark the 50th anniversary of Mali's independence from France. One is the visitor's facility at the Great Mosque of Mopti, a public space for the display of Mali's vernacular mud architecture. The building was completed following the 2006 renovation of the adjacent mosque. During the 14th century, the expansion of Islam in Mali led to the creation of adobe brick mosques with elaborate mud turrets. An internal wood lattice structure doubles as a scaffold system for the annual re-application of mud. The second project is the National Park of Mali set in the capital of Bamako, representing one of the most important civic projects ever to take shape in West Africa.
The first time I met Kéré was in New York, at the Museum of Modern Art exhibition Small Scale, Big Change: New Architectures of Social Engagement, curated by Andres Lepik, which featured Kéré's masterful 2001 Gando Primary School. Here in Dogon country, our afternoon spent conversing together reframed my understanding of Kéré's attitude towards architecture as a complex mediation between technology and the vernacular. It was Kéré's first visit to Dogon country, an area populated by a people who arrived here in the early 15th century. The location of their original homeland is unclear, although one oral tradition places it in present-day Burkina Faso. As Kéré observed, "Dogon country is a very special place. The landscape is not something nice and domestic like it is at home in Europe. In Dogon country it is spectacular. When you're there, you think about the architect, and then you think about what nature is able to do."
Massive baobab trees grow at a distance from one another, since their massive roots need space. These trees have textured bands where the Dogon cut away part of the bark for medicinal and ritual purposes, and the bands form a pattern across all the baobabs. While walking along the savannah plain set between two sheer cliffs fringed with Dogon villages, Kéré commented how the array of baobab trees resembles architecture. "You have a single element, when you see these beautiful trees," Kéré reflected. "One baobab is solitary—it's like a single note. With many trees, you have a rhythm. You need repetition, but also different notes. The space in between the trees is so great. It's architecture."
The "in-between" space of the baobabs is a concept carried into Kéré's Gando Primary School, and again mirrored in his aspirations at the National Park of Mali. For the urban park, the Aga Khan Foundation commissioned Kéré to design the entrance pavilions, a restaurant and a sports complex. In partnership with Mali's government, the foundation converted the remains of a French colonial-era botanical garden into an immense park for strolling, relaxation and exercise. The rational stone walls of the sports complex also form the "in-between" space, an enclave where people can interact, take refuge and retreat from the bustle of urban Bamako.
Kéré asserts: "For me, the outside space was the most important—
the space in the middle of the park. For the sports centre, it is a
special area that is open but also closed. The walls give intimacy
to the space where you do the sport."
Kéré designed the entrance pavilions, the restaurant and sports complex with a similar pattern. A base clad with vertical bands of stone is then capped with a steel-truss roof. The roof functions as a shading device and directs rainwater, while also allowing natural ventilation in all spaces except the restaurant, where the client insisted on installing air conditioning.
Kéré's aim was not simply to recast the vernacular, nor impersonate the modern aesthetic through building with local materials. Instead, his project is marked by the search for a tectonic rationalism. Kéré creates an architecture of lightness by doubling the number of members in each truss in order to make finer, more delicate parts. The steel-truss roof appears to float away from the base, a tectonic trait of Mies van der Rohe's Crown Hall at the Illinois Institute of Technology. "They were using local stone for the pavement, and I suggested using it for the walls," explains Kéré talking about the facades. "But they said it wasn't possible. Usually they cut the stone in a natural way. Instead I told them to make it rational, not decorative. So in the end they cut stones in different sizes to make a kind of repetition." The horizontal bands of stone create patterns that contrast with the upward force of the roofs.
Kéré notes that Mies van der Rohe and Louis Kahn were the architects who had the greatest influence on his development, which explains his mediation between technology (innovation) and tradition (the vernacular). This balanced approach is difficult in Africa, where projects tend to carry either a primitive aesthetic or a high-tech curtain wall to mirror the Western notion of progress.
In contrast to Kéré's complete control over the building process in the Gando Primary School, the park buildings followed a different design path. The fabrication of the truss roof was the most problematic aspect. Although Kéré produced a prototype in Burkina Faso to demonstrate the feasibility of making the roof on site, the Aga Khan had it fabricated in Turkey since local engineers could not be found. Kéré wishes to bring technical prowess to Mali that can be achieved by the local people, yet such incremental advancement is at odds with the client's aspirations to produce a powerful symbol of progress.
Kéré stands apart in a world where architecture is sometimes
viewed as an interchangeable product, and the architect as
producer. In early discussions regarding the design of the Mopti
project, Roberto Fabbro of the Aga Khan Trust for Culture asked
Kéré to come up with a building similar to Gando. Kéré answered,
"I am not a supermarket." He is instead a process-based architect,
applying a different tactic in response to each new condition.
He built the centre, as in Gando, with bricks stabilised by earth and five per cent concrete, and built a similar truss roof. For the interior, meanwhile, his design features innovative shallow vaulting between the steel members.
Kéré lies between various worlds—one morning he wakes up
in developed, globalised Germany, the next day he can be in
Burkina Faso, and then in Mali, with clients who wish to design
for the future. As an architect, Kéré has the delicate task of fusing
design with national identity, vision and reality.
