Nigeria

Nigeria spans mangrove and lagoon coasts, the Niger-Benue river system, forest belts, central plateaus and northern savannas approaching the Sahel. This geographic range produces major differences in rainfall, temperature and building culture. Earth, laterite, timber and thatch remain important vernacular materials, with courtyard compounds widespread in many regions and highly developed earthen traditions in the north; humid southern areas favour shade, ventilation and generous roof overhangs.
