This thesis explores the effect of climate on the development of high density housing. With the situation in Lagos there is a tendency to neglect the effect of climate. The low income housing project proposed under the Ijaiye housing scheme is used as a vehicle to investigate this climatic concerns. The conditions that generated the design included site conditions, climate, human comfort criteria, building materials, and construction. The issues that were dealt with include ventilation, protection from direct solar radiation, treatment of common spaces, orientation, drainage, and the choice of building materials. The design solution submitted in this thesis is influenced by various sources from the field of tropical architecture with the understanding that these studies are not definitive and that further investigation still needs to be made. / Master of Architecture
