Housing is the most omnipresent urban typology. Housing is also the essential architecture of the human condition. Perhaps more than any other architectural species, housing determines how urbanites construct their lives and build their shared futures. The full-scale Russian war against Ukraine has disproportionally affected housing and residential infrastructure. The destruction is so targeted and the damage so significant that it has disfigured entire neighborhoods and erased entire cities. With the scale of damage and loss in mind and the future wide-ranging reconstruction that will inevitably occur after the war, this study examines the history and typologies of mass housing in Ukraine. It does so to evaluate what is lost, explain the diversity of modes of urban living in Ukrainian cities, and finally, reconsider the narrative of how Ukrainian housing came about. The study covers the last 100 years: the time of the most dramatic expansion and changes in the character of Ukrainian cities.
