Currently Addis Ababa is recording high rates of urbanization. And urbanization comes with emerging demands. One of these demands is access to urban space which is managed through new ways of space usage. One of these ways is multi-functionality of streets other than being walk-ways or drive-ways. These spaces accommodating various activities can be termed as conscious spaces, functioning as a self-shifting living organism; referred here as Interface Spaces. They are easy to relate to the inhabitants and to the settlement as a whole where they are the medium of spatial and economic transformations besides being the social link. Thus, the “in between” space of house against street, which is prone for diverse adaptation, is the focus of this research. It aims in analyzing interface spaces as part of the urban spatial pattern where space is being produced and used in relatively new way. This shift away from the norm/design forms a space that is very unique to the city alone. The study reaches to a conclusion where Interface Spaces take this role leading towards a new urbanism, Interface Urbanism.
