The concept of tropical architecture is one that was constructed in the 1950s to link the work of modernist practitioners in a number of locations outside the West. Tropical architecture has been represented as a form of critical regionalism, in that it offers a language based in the conditions of the non-western world. While this may be true of the movement in the Americas, in the case of the British colonies of West Africa tropical architecture was located within the networks of modernist and colonial culture as much as it was place bound.

Tropical architecture was established in the metropolitan architectural circles of the 1950s through the use of the term in books and journals, a conference and a course of specialisation in London. These forms of support assisted architects to create modern architecture in far-flung sites, under difficult conditions. Despite this enmeshment of the peripheral sites of practice with the colonial metropolis through communications, tropical architecture was seen as something other than colonial architecture. The changing political and economic opportunities at the end of the colonial period prompted architects to develop a post-colonial identity for architecture, which was done through the representation of their approach as one that could transcend national boundaries. Tropical Architecture in the Humid Zones , by Fry and Drew explicitly offers support for an imaginary architect who comes from a generic tropical zone.

The influence of the metropolis on the culture of tropical architecture remained significant, even after independence. While the consistency of approaches that marked the work of the 1950s has been replaced by a multiplicity of attitudes to design, the contemporary literature, curricula and research on African architecture share an emphasis on its climatic conditions. This content, in turn, ties the approach to authoritative sources in the West, giving it an identity that links the local and the global in complex and interdependent ways.
