Examination of Interventions and Defects on Façades: The Case of Selamsız Low-Cost Mass Housing in Istanbul, Türkiye

Abstract

Conservation of 20th century mass housing is discussed considering their heritage value. On the other hand, intervention might be required since they do not meet the today’s requirements and defect might have occurred. In that case, primary objective should be the managing of changes to sustain existing building stock. Within the study, the current situation of one of the modern period mass housing projects in Istanbul/Türkiye Selamsız Low-Cost Mass Housing was documented for interventions and defects on the front façade. Besides, determining the frequency of intervention and defects, examining relations between them and external factors, and identifying reasons for the interventions were also aimed. Data collected about 108 existing buildings and photographic research was made through literature review/archive search/site visits. Collected data were evaluated with a systematic order. As a result, almost half of the defects are caused by interventions on building/element/component scale to fulfil spatial and performance requirements.
