AFRICAN architecture is as diverse as the different cultures and peoples that make up the continent.
Islam and Christianity have produced astounding churches and magnificent mosques. The mix of colonial and modern influences have clashed in the urban environment, in some cities economic or political turmoil resulted in an eclectic clash of styles and little consideration of aesthetic beauty, and in rural areas the local environment was often the driver in the influence of design and structure.
Recently, however, something different has sprouted on the continent. There is a new breed of architect whose work is suffused with social responsibility, and the designs that emanate from them are nothing short of genius.
Their structures created are carefully crafted to fit in with the various demands or pressures of modern day society in Africa.
Here we take a look at a few examples of these extraordinary architects:
Diébédo Francis Kéré
Even though he’s had international success and is based in Berlin, Germany, this hasn’t stopped Burkinabé architect Kéré from making waves back home, in Burkina Faso. Founded in 2005, Kéré Architecture is dedicated to supporting the educational, cultural, and sustainable needs of communities in Burkina Faso through sustainable building practices. Using his formal training as an architect, Kéré has developed strategies for innovative construction by combining traditional Burkinabé building techniques and materials with modern engineering methods.
His projects in Burkina Faso are impressive. In the village of Gando, his birth place, Kéré made a great push for education by constructing schools, along with the help of the local community, and the necessary teacher housing, library and wells to support them.
Each structure was carefully conceived to support the learning environment and be as adaptable as possible to the areas geography. Mud brick walls combined with raised tin roofs use material which is locally available and keep the buildings cool and dry. The school library has a roof with traditional clay pots that have been cut in half and inserted in the ceiling, letting in light and allowing air to circulate.
In June this year the “Surgical Clinic and Health Centre” was opened, serving a population of over 50,000 people from the town of Léo and its surrounding communities. In planning for the most sustainable building solution with least ecological impact, the main construction of the centre is compressed earth bricks.
Their high thermal mass capacity allows them to absorb the cool night air and release it during the day, helping keep the interior spaces cool. The clinic also features ten large overlapping roofs that protect the walls from rain and shade the interiors from the hot daytime sun. The vibrantly-coloured buildings are sited around a central outdoor corridor – a friendly characteristic which is important for the success of the centre, as it attracts patients who would normally not seek medical attention.
Kunlé Adeyemi is a Nigerian architect and urbanist – heavily influenced by the fast-paced urbanisation of African cities. After studying at the University of Lagos in Nigeria, followed by Princeton in the US, Adeyemi founded NLÉ – an architecture and design practice based in Amsterdam, Netherlands.
One of his recent projects has focused on his homeland and its fast urbanisation rate. In 2013 Adeyemi completed the “Makoko Floating School”, a prototype floating structure, built for the water community of Makoko, located on the lagoon heart of Nigeria’s largest city, Lagos. This pilot project took an innovative approach to address the community’s social and physical needs in view of the impact of climate change and a rapidly urbanising context.
At a cost of less than $7,000 the school accommodates 100 students, uses 256 plastic drums to keep it resting on top of the water, and the frame is constructed from locally-sourced wood. Electricity is provided by solar panels on the roof, and rainwater harvesting helps to keep toilets operational.
Adeyemi has been able to produce an ecologically friendly, alternative building system that could revolutionise Africa’s urban water societies. Now, he is taking the project a step further. He is now looking to expand on his pilot and create a group of floating structures in Makoko, allowing its estimated 250,000 inhabitants better access to sanitation, fresh water and waste disposal.
Another notable Adeyemi project is the community-built Chicoco radio, in Port Harcourt. The radio station is a floating media platform that provides a voice to 480,000 residents of Port Harcourt’s waterfront slums which line the creeks fringing the city. The governor plans to demolish them all. Not only is the innovative design sustainable and resistant to flooding, but the architecture has also merged with media to become a platform for modern communication and civic participation.
Zimbabwean architect Mick Pearce is dedicated to designing low maintenance buildings with low running costs, using renewable energy systems. His aim is to ensure buildings are suited to their natural environment and the people who use them. Over the past 20 years his work has focused heavily on bio-mimicry – an the imitation of natural processes and the use of natural materials.
One of his most famous examples is the Eastgate Centre in Harare. Largely made of concrete, the Eastgate Centre has a ventilation system, which operates similarly to the self-cooling mounds of African termites. Because of its altitude, Harare has a temperate climate and the typical daily temperature swing is 10 to 14 °C, making a passive cooling system a viable alternative to artificial air-conditioning. Passive cooling works by storing heat in the day and venting it at night as temperatures drop. Without relying on conventional air-conditioning or heating the building stays regulated all year round, dramatically reducing energy consumption and the building uses 10% of the energy a conventional building of its size would use.
Tsai Design Studio
Architectural genius is most of the time a combined team effort, on the part of a firm or when two firms come together. It would be impossible to have a list looking at architectural efforts linked to social reform or environmental sustainability without mentioning South Africa’s Tsai design studio. Even though it was established in 2005, this small team of architects has earned a number of design accolades and awards for its architecture and design work – though their community work, re-purposing shipping containers is what stands out.
The studio first became famous for this in 2010 when South African shipping company Safmarine commissioned the studio to develop several designs using recycled containers for community projects. The first Sport Centre prototype was built under a month to coincide with the 2010 FIFA World Cup. The centre allowed disadvantaged children and communities to be twinned with a Dutch football club who trained local coaches with football techniques and life skills.
The design included a grandstand seating social area, a sheltering roof and an advertising billboard and movie screen as an extension of the roof structure that folds down vertically at one side. This can be used as a possible source of income for the sports centre or be converted into a movie screen for the children. Since then, the containers have been re-purposed for a variety of other community projects.
One example is “Vissershok primary school”. Sponsored by three South African Companies; Safmarine, Afrisam and Woolworths, “Vissershok primary school” was created. Serving as a classroom in the morning and a school library in the afternoon, the container provides a well planned environment for the pupils. The large roof keeps out direct sunlight and reduces heat while the windows staggered along the sides of the container ensure cross ventilation.
