Warszawska Spółdzielnia Mieszkaniowa (WSM) is a housing cooperative based in Warsaw, Poland, with roots in the Polish cooperative and trade-union movements. It was established on 11 December 1921, when its founding members formed the first nine-person supervisory board; its statute was subsequently registered by the Warsaw District Court in January 1922.234 The founding group included activists such as Jan Hempel, Maria Orsetti, Stanisław Tołwiński, Stanisław Szwalbe and Bolesław Bierut.8
WSM’s original purpose was to provide members with affordable, healthy housing built through collective self-help, while also addressing members’ cultural needs.8 Housing development began in Warsaw’s Żoliborz district after the cooperative received land near Wilson Square in 1923.8 Over the course of its history, WSM has developed housing estates and residential colonies in several Warsaw districts, including Żoliborz, Rakowiec, Koło and Białołęka.10
The cooperative’s principal activity is the management of residential property, a function it states it has performed since 1921.1 Its managed resources include residential buildings, commercial premises and related infrastructure located in Warsaw.9 The organisation’s website currently describes a portfolio of 491 buildings and more than 27,000 apartments.1 Earlier WSM information states that the cooperative has more than 33,000 members and serves approximately 100,000 residents.10
WSM operates primarily within Warsaw and is therefore a local organisation, although its scale makes it one of Poland’s largest and oldest housing cooperatives.9 Its registered office is listed at Elbląska 14, Warsaw.611 The available sources identify historical founding officials, but do not establish the current leadership team.
