COALESCE interrogates the social condition in Marseille, which has manufactured the segregation of a community settled on an industrial wasteland, by neighbouring southern communities. This issue has materialised and matured over the course of the cities long and rich history, catalysed by in uxes of immigration as a result of war and con ict, which in turn has lead to overpopulation and the collision of cultures, languages and religious beliefs within the city. The scheme proposed seeks to promote social integration, a complex notion that demands the consideration of various elements within the realms of politics, economy and culture.
