The iconic competition-winning design for MTN House, Accra was lozenge-shaped on a plan offering a curved elevation to independence Avenue. The circulation core, however, was extracted from the floor plate into the separate tower at the rear, connected to the main building by bridges. The curtain wall was to be shaded at each level with horizontal aluminum sun louvers. A glazed, enclosed atrium spanned the height of the building from the basement to the roof and at ground floor level the floor of the atrium was glass allowing natural light to penetrate the basement.
