Osiedle Robotnicze in Kraków, Workers' housing estate in Dębniki, Kraków, Poland

Osiedle Robotnicze is a workers' housing estate on Praska Street in Dębniki, designed by Stefan Piwowarczyk with fourteen single-story blocks under the existenzminimum program. Each flat of 36 m² has a room, kitchen, hallway and bathroom. Eight buildings stand on the odd-numbered side and two on the even side; a 1950s addition of one floor and three buildings altered the original forms.

The Workers' Settlement Society launched the estate to counter a housing shortage for labourers; construction started in April 1935 near the Vistula, and the first two blocks were handed over that November. Funds ran out in 1938, leaving eight buildings on the odd side of Praska Street and two on the even side. In the early 1950s all blocks gained one storey and three buildings plus a school were added, completing Stefan Piwowarczyk's plan of fourteen blocks while altering the original forms.

The complex reflects a direct, no-frills approach to housing design, with clean lines and minimal decoration that workers could easily maintain and understand. The Social House building now functions as a cultural center and remains a gathering place for the neighborhood.

The complex is located in a residential neighborhood and is easily accessible on foot, with different buildings arranged around open green spaces. Visitors can freely enter the public areas and explore the grounds, though it remains an active residential area where people live.

The design is often credited to Fryderyk Tadanier, but the original plan came from Stefan Piwowarczyk; Tadanier only served as site manager. Part of the flats went rent-free to workers over 50 who had fought for Polish independence.
