The Niger Tower is a large-scale project which aims to create a modern business center meeting the diverse needs of small, medium and large businesses. MOST is responsible for the extension of the tower and all of the interior design; this includes various services, reception, VIP lounge, and cafeteria, reception rooms, meeting rooms, offices and apartments. To meet expectations, MOST has used all its know-how to create optimized spaces adapted to efficient and pleasant use, all with a refined workmanship combining luxury and modernity. In order to work around a constraint pertaining to the lighting of the main room, we designed a raised roof with a diamond shaped structure with LED lighting. The right blend between designs rooted in African aesthetics and a contemporary approach to designing space.
