In urban areas only the emerging middle class can afford government-built housing. Other migrants to the towns buy plots of land and build cheap shacks of corrugated iron and waste materials, principally near Port-Vila and Luganville. The vast majority of villagers still build their own homes from local materials. The majority of dwellings are traditional Melanesian houses with earth or coral floors, no glass windows, and palm, bamboo, or cane walls and roofing. The most widely used exterior construction material was bush. In February 1987, a cyclone damaged 95% of the buildings in Port-Vila. In 1998, 87% of the population had access to safe drinking water.
