The Oberwarter Siedlungsgenossenschaft (OSG) is a cooperative housing organisation based in Oberwart, Burgenland, Austria. Its official legal name is Oberwarter gemeinnützige Bau-, Wohn- und Siedlungsgenossenschaft, registrierte Genossenschaft mit beschränkter Haftung.38 The organisation was founded in 1951 in Oberwart by 16 settlers who joined together to build their own single-family homes.1 Its construction activities began in 1952.6
OSG develops, manages and provides housing, including apartments, terraced houses and other residential projects. Its website also lists immediately available homes, a tenant-substitution exchange, commercial premises and new-build projects.1 The organisation states that it focuses on contemporary, affordable housing and has adapted its construction practices to environmentally conscious, ecological and energy-saving approaches.1
The cooperative operates across Burgenland rather than in a single municipality. OSG describes housing expertise in 165 municipalities in the province, while another company page states that 165 of Burgenland’s 171 municipalities are OSG municipalities.12 It therefore has a predominantly regional scope, with customer centres in Oberwart, Eisenstadt and Neusiedl am See.6
KommR Dr Alfred Kollar is listed as a member of the executive board, chairperson and managing director at the Oberwart customer centre.5 The organisation’s registered office and headquarters are at OSG-Platz 1 in Oberwart.38 OSG’s Instagram account is listed under the handle “osg.oberwart”.11 No official LinkedIn company page was identified in the available search results.
