ABSTRACT
Africa is a huge continent containing more than 20 percent of the earth’s land area. It extendsroughly 5,000 miles (8,000 km) south from Tunis on the Mediterranean to the Cape of Good Hope and is nearly as wide as it is long. Climatically the continent is divided into broad horizontal bands ranging from moderate Mediterranean seasons to extremely arid desert. Such a profound range of temperatures, the varying amounts of rainfall, and the many kinds of vegetation over this vast expanse has led to a variety of building solutions over the centuries.
