On 1 July I will deliver the paper “Banks, Sweat and Shelter in Addis Ababa: Sites and Services in Performance” at the No Cost Housing Conference, hosted and organized by the ETH Wohnforum—ETH CASE at the ONA Building of ETH Zurich in Zurich-Oerlikon. The two-day conference is developed in collaboration with the Hub on Informal Urbanism of UNI (UN-Habitat’s Partnership with Universities Worldwide). My paper will be presented in the thematic Paper Session "Community Based Housing Strategies", moderated by Dr. Jennifer Duyne (UN-Habitat) & Dr. Marie Glaser (ETH Wohnforum-ETH CASE). My paper aims at examining the nexus between design decisions and the performance of a site and services settlement through time. I will discuss the case of the Nefas Silk sites and services settlement, a World Bank-funded project with approximately 3500 serviced plots developed in Addis Ababa in the 1980s. The results and insights of the conference will lead to a joint statement, submitted to the executive office in preparation of Habitat III in Quito (17.—20. October).
