Dutch architectural firm Groosman has unveiled a new Rwandan art and cultural centre which will feature two huge cantilevered wings.

The Rotterdam-based studio worked with engineers Geelhoed Group on the design of the Kigali Art & Culture Centre, which will be located on the outskirts of Rwanda's hilly capital. The cross-shaped block will be decorated with traditional African geometric patterns and will feature two cantilevered sections overhanging an elevated plaza, offering relief from the sun and rain, together with views of the surrounding landscape for those inside.

The Kigali Art & Culture Centre is one of several architectural projects that make up a new masterplan for the city, along with a children's cancer treatment centre by David Adjaye.

The country is frequently described as a ‘land of 1,000 hills’ and the centre will sit at the intersection of the city and its surrounding wetlands and mountains. Two further buildings – a hotel and office complex, plus a housing block – will sit on the plaza, while a subterranean shopping centre will be situated below.

Like the facade of the cultural centre, the raised public square will be covered in symbolic patterns and divided up by a grid with sections measuring 2,500sq m (26,910sq ft), each with its own design.

“Our design concept for Kigali Art & Culture Centre is inspired by African art, crafts and culture,” stated Groosman.

“Very typical of this African identity is the use of patterns. These form the basis for our design.”
