The projected cost of the renovation exceeded PLN 100 million, with completion scheduled between 2022 and 2024. By August 2018, the Council of the Capital City of Warsaw had earmarked PLN 183 million specifically for the Congress Hall renovation, as part of its long-term financial planning. In 2019, the competition for the modernization of the hall was concluded. In 2021, it turned out that the amount reserved by the city was too small. The earliest completion date for the renovation is around 2025.[3]
