The architectural concept for the Peace and Security Building of the African Union (AU) is an architectural rendering of the AU’s role in the peaceful resolution of conflicts among member states. The flexible use of space is a key component in this open, democratic configuration, providing a European architectural approach fitting for the African context.

Inside, the structure offers the range of spaces needed for the AU’s complex internal workflows. Outside, the institution signals its openness by prioritizing its function as a public space. The ground floor of the building is an open plan space that only takes shape when reconfigured for various types of public usage. Three layered office levels in a square shape cordon off the public space and define the ground floor structure. The core of the building – the identity-shaping plenary chamber of the AU’s Peace and Security Council – is a circular hall with broad seating tiers. A generous staircase leads from the entrance area directly into the plenary chamber. The three expansive upper floors, outfitted with flexible configuration of office and conference space, are organized in an inverse fashion: the workstations face the interior courtyard to allow access to natural light and ventilation. This reverse configuration positions the access routes in the exterior envelope, serving as both a boundary for internal communications and an interface between the non-public and public space.
