Architecture for the developing peoples; as they are now well called-the millions of India, Africa, and the Middle East who are fast becoming part of the modern world is a very great problem, particularly since education is acquired more quickly than wealth. An architect, if he wishes to devote part of his life to helping such people, should know the basic requirements of tropical building and the great difference in building for a hot-dry or a hot-wet climate. The subject is a complicated one, for there are differences not only in housing but town planning and the methods of siting buildings.

Grasping all the technical difficulties is only the beginning of the problem, because it is likely that poverty will rule out modern methods of construction, and that stabilized earth, rather than curtain walling, will prove the right answer.
