Citibank Head Office – Nigeria
Deliberately designed with a low-tech facade, the building is the head office of the prestigious Citibank Nigeria Limited. The primary structure consists of four office floors with a bank branch on the ground floor; a provision for an additional floor can be accommodated should the need later arise. The building is energy-efficient through the use of insulated cavity walls and double-glazed windows surmounted by aluminium sun louvres to minimise glare and heat gain from solar radiation. The engineering services in the building are state-of-the-art, and were designed on the basis of Nigerian, British and American engineering and building codes.
