Britain began to sponsor economic development in its colonial territories under the Colonial Development Act of 1929. The first CDA project was for housing on Antigua; other schemes for the Leewards soon followed. The isolation and poverty of this colony highlighted the practical difficulties of promoting development. Challenges included the negotiation of new methods of administration. Governors conceded autonomy in return for assistance; under pressure from Treasury, the Colonial Office learned how to supervise far-flung projects, while its subject departments gained influence at the expense of the regional. Trial and error in the design and supervision of projects on the Leewards provided information about what types of housing policy were cost-effective and acceptable locally. By the 1950s the advice of United States experts also made itself felt. Funds provided under the CDA and later development Acts were limited, but they transformed the machinery and influenced the content of colonial policy.
