The Pritzker Prize, architecture's most prestigious award, was awarded Tuesday to Burkina Faso-born architect Diebedo Francis Kere -- the first African to win the honor in its more than 40-year history.

Kere, 56, was hailed for his "pioneering" designs that are "sustainable to the earth and its inhabitants -- in lands of extreme scarcity," Tom Pritzker, chairman of the Hyatt Foundation that sponsors the award, said in a statement.

Kere, a dual citizen of Burkina Faso and Germany, said he was the "happiest man on this planet" to become the 51st recipient of the illustrious prize since it was first awarded in 1979.

"I have a feeling of an overwhelming honour but also a sense of responsibility," he told AFP during an interview in his office in Berlin.

Kere is renowned for building schools, health facilities, housing, civic buildings and public spaces across Africa, including Benin, Burkina Faso, Mali, Togo, Kenya, Mozambique, Togo and Sudan.

"He is equally architect and servant, improving upon the lives and experiences of countless citizens in a region of the world that is at times forgotten," said Pritzker.

Kere won plaudits for his 2001 project for a primary school in Gando village, in Burkina Faso, where he was born.

Unlike traditional school buildings which used concrete, Kere's innovative design combined local clay, fortified with cement to form bricks that helped retain cooler air inside.

A wide raised tin roof protects the building from rains while helping the air circulate, meaning natural ventilation without any need for air conditioning.

Kere engaged the local community during the design and building phase, and the number of students at the school increased from 120 to 700, the Hyatt Foundation said in its release.

The success of the project saw the creation of an extension, a library and teachers' housing in later years.

In Kere's native Burkina Faso, his accolade was hailed as a reminder that Burkina Faso should be known internationally for more than a violent jihadist insurgency that has gripped the country.

Groups affiliated to Al-Qaeda and the so-called Islamic State group have killed more than 2,000 people and displaced at least 1.7 million.

"In the current pain of the security crisis, our country must remember that it is also the nation of exceptional men like Francis Kere," said Ra-Sablga Seydou Ouedraogo, of the non-profit Free Afrik.

Nebila Aristide Bazie, head of the Burkina Faso architects' council, said the award "highlights the African architect and the people of Burkina Faso."

In 2017, Kere became the first African architect to design the Serpentine pavilion in London's Hyde Park, a prestigious assignment given to a world-famous architect every year.

He was also one of the architects behind Geneva's International Red Cross and Red Crescent Museum and has held solo museum shows in Munich and Philadelphia.

"I am totally convinced that everyone deserves quality," he said in his office, where he celebrated his award with his team.

"I'm always thinking how can I get the best for my clients, for those who can afford but also for those who can not afford.

"This is my way of doing things, of using my architecture to create structures to serve people, let's say to serve humanity," Kere added.
