The Sipopo Congress Center was designed for the city of Malabo, capital of Equatorial Guinea. Due to the high amount of solar radiation, this two-storey building features a semi-transparent metal envelope that protects the interior, yet provides and optimal amount of natural lighting. The lacy texture of the mesh grants a shady interior during the day, while providing an appearance of transparency at night.  Istanbul-based Tabanlioglu Architects have designed the building favoring natural materials like timber, natural stone and glass, with particular attention to locally available sources.

Entering the main lobby designed as a double height atrium, the interiors grant a feeling of spaciousness and create a wide circulation zone. A map of Africa made up of lights welcome the leaders at the entrance and accentuates the communicative nature of the Congress Center. The main conference hall, a rectangular space at the first floor with a circular seating design, is situated amid the structure and accessed through the connecting lobbies at three sides. VIP lounges are situated at the ground floor, adjacent to the main conference hall. The restaurant, overlooking the bay, is flanked by the foyer at two intersecting sides. A transparent connection bridge links the new building to the existing one.
