ENIn most post-socialist cities modernist mass housing comprises a remarkable share of urban housing with a substantial population living there. Therefore, socialist large housing estates (LHEs) have been a fruitful source for research to gather systematic knowledge concerning segregation and housing preferences. Less is known, however, of contemporary LHE-related urban policies and planning interventions. This study asks how in the post-privatisation era, when former governance structures had disappeared, did new urban governance arrangements related to LHEs begin to emerge. We take a closer look at two LHE areas in post-Soviet cities: Annelinn (Tartu, Estonia) and Žirmunai Triangle (Vilnius, Lithuania). The research is based on expert interviews and document analysis exploring the formation of governance networks in both cities since the 2000s and the rationale behind recent planning initiatives. A common new spatial expectation for housing estates’ residents and contemporary urban planners seems to be a perceptible differentiation of the public, semi-public and private spaces, instead of the former modernist concept of free planning and large open areas between buildings. As the heightened planning interest came at a time when European cohesion measures supported urban budgets, it also has led to tangible investments, and builds the consensus that the public sector should return to post-privatised LHEs. We argue that public space has been a great medium for modern governance networks and bringing LHEs back to the urban agenda in post-socialist cities and that the lessons learned in the post-socialist context provide an insight for the wider global marketization debate. Keywords: post-privatisation period, large housing estates, public spaces, governance, urban planning. [From the publication]
