The Angola pavilion - made for Expo2015 in wood and concrete - was presented as a well-identifiable sequence of volumes and elements: the "exhibition machine", the representative wing/central offices, the concluding volume of the stage and the technical and management services, the vertical connection wing of representation (main staircase). The unifying element was the wing in line on the north side, where the vertical connection systems (stairs and ramps) and the technical and service spaces were placed. The project developed the idea of the "Exhibition Tree" which, in turn, resumed the meaning and centrality of the "Imbondeiro" (Baobab) in the Angolan culture: the tree was transformed into the bearing structure of the entire "Exhibition Machine", supported by a central "castle" consisting of four large pillars and two powerful truss beams of over thirty meters. The articulation of the volumes was clearly readable in the plans: - The "Exhibition Machine", with the main exhibition path, characterized by a large space at full height;- the "representation/conference wing", seat of the Commission offices and the "temporary exhibitions/exhibitions" area; - the "technical wing and stage", with the management and press areas, as well as the stage for outdoor performances; - the roof garden: Angolan nutrition learning and experimentation area (garden, laboratory and restaurant). A large "scenic stage" solved the main prospectus of the pavilion as a key element for external "communication". A part of the pavilion was dismantled and recovered in Angola for the realization of a museum of the Angolan culture.
