The PZKO House on Kopernikova street was constructed using the local group's collective effort. Its ceremonious opening took place in 1973. The seat was named after Adam Wawrosz. The house is adjacent to the elementary school and the forest park of Třinec. It doesn't have its own garden. The main hall for 70 people is located on the building's first floor. Next to the hall, there is a small kitchen, a bathroom, and a storeroom. On the ground floor, there is a secretariat, a storeroom, a bathroom, and two clubrooms which are currently rented long-term. In the last few years, the group invested in the modernization of the kitchen, heating, and wiring. The roof has also been replaced. The PZKO House is a place for the group's meetings, meetings of other organizations, and also private social and sports events.
