Diébédo Francis Kéré has been commissioned to build a new national assembly building for Burkina Faso in Ouagoudougou, capital of the West African country made up of over fifty ethnic groups. Born in the Burkina Faso village of Gando and working from his office in Berlin, Kéré has designed a stepped pyramid of concrete and stone with passable roofs and terraces incorporating food gardens where new farming techniques will be tested. The inside accommodate a chamber seating 127 representatives and a garden inspired in local tradition, evoking the meetings of African village elders in the shade of a large tree, gathered to discuss important matters. The masterplan also includes transforming the old national assembly building, which was destroyed in 2014, during the popular uprising against dictatorial rule. It is to be turned into a monument in remembrance of those who lost their lives during the conflict, with a tree-planted square beside it. The project was unveiled at the 15th Venice Architecture Biennale, in an exhibition on view through 27 November.
