Slum communities are considered an eyesore in the urban landscape,yet 44% of Metro Lagos’ population is living in them.These settlements grafted on the fringes of the city core are fragmented,plugged away from the services of the city center.Slums are made up of the urban poor and have substandard housing in squalor conditions.Affordable housing within the city is lacking and so the expansion of these blighted areas is increasing.The increasing density in this third world city have forced a number of migrants from the countryside to the periphery of the city where residents have relocated to live along the riverbanks and further into the lagoon.Makoko,a slum community made up of 90 hectares of partially reclaimed land is a community threatened by rising sea levels.The Makoko waterfront slum rehabilitation study aimed at comprehensive solutions to the problem of housing and spatial arrangement in Makoko community.It seeks to understand current slums solutions and understand how slum rehabilitation and resettlement projects are achieved.The study reviewed past literature and publications in investigating the formation and anatomy of slums and a further understanding of the structure,growth and role of slum communities.In addition,the study looked into the concept of floating typology and the adaptation of buildings to aquatic environment.The study adopted the analysis into successful slum upgrade programs in developing countries to answer the generic “how”,“why” or “what” questions.Finally,analysis of This thesis will consider how floating architecture can exist,how it addresses the sprawling urban density and responds to natural disasters and long-term sustainable recovery.
