In this paper I will focus on the rising of the “diaspora neighborhoods” in Mekele, the capital of Tigray region (Ethiopia). In particular, I will consider the diasporic commitment in the house-building process, disconnecting it from “homecoming” projects, and linking it to the reproduction of the diasporic affective networks. Drawing on an ethnography of an apparent failed return from the diaspora, I will anthropologically explore the unsettled dwelling practices constituting the diaspora houses fruition. I will specifically focus on the transnational regimes of mobility facilitating, impeding and orienting the housebuilding processes, as well as on the interconnection between the movers and those who stay behind in the housebuilding decision. Diaspora houses, in this perspective, will be analyzed as proper infrastructures of mobility, as nodal points of the familiar and affective networks sustaining the diaspora social life.
