Addis Ababa is a city experiencing a huge population boom, and where the vast majority of housing can be classified as “slum”. State-owned kebele housing, which houses an estimated 40% of the city’s inhabitants, has very low rents but is not maintained, leading to deterioration. Thus, the city is left with a severe shortage of adequate housing. Current state-led developments intended to alleviate the acute housing problem do not address the specific situation of Addis Ababa, and do not allow for the flexibility and adaptability that is required by residents. This research and design project focusses on a specific site in Gerji, owned by the Federal Housing Corporation, and proposes a new model for mid-density, low-rise development which is specific to the context of Ethiopia and suitable for the varying and different living patterns of people in Addis Ababa. The project includes ethnographic research, looking into the lifestyles and daily habits of local residents, as well as documenting their homes and living spaces. Further research was conducted into vernacular and historical building styles and construction methods present in Ethiopia, which was used to inform the design and better understand the specific context of Ethiopia. The research concluded that many different living patterns must be accommodated in a new development, and that this should allow for flexibility and adaptability as household incomes and expectations change over time. Moreover, homes should be suitable for the climate and materials and construction techniques should be informed by local customs in order to aid social sustainability. Finally, tenure options, functions and typologies should be mixed to create a diverse and resilient neighbourhood. The proposed design addresses the research by offering three distinct typologies of building, all of which offer the flexibility needed to allow for different functions and uses. These three typologies are aimed at different sectors of the community and are proposed to be offered in different tenure models. The design is simple and uses adobe bricks and laminated bamboo lumber as its main construction materials. These both use raw materials that can easily be sourced locally and can be processed cheaply on site, using local labour. Ultimately, the proposal achieves a density similar to that of local state-funded housing developments, known as “condominiums”, suggesting that this more varied and site-specific approach to tackling the housing shortage is feasible for Addis Ababa. Adopting such an approach, which looks to local customs and vernacular styles for inspiration, is a radical alternative to the unsustainable route currently being taken in Addis Ababa.
