The clubroom of the local PZKO group of Košařisky is located on the premises of the former Polish school constructed after the second world war. The rather small building features a hall that can accommodate up to 35 people. There is also a kitchen, a hallway, and a bathroom. The guests can utilize a garden with benches and a bonfire site. The building was reconstructed in 2019 – the hallway's windows were replaced and the kitchen was modernized. The replacement of the main hall's windows is planned. The clubroom is located near the town center above the schoolhouse.
