This article examines the impact of economic factors, such as changes in interest rates and inflation, on the primary housing market in Poland from January 2019 to September 2022, with particular focus on the Covid-19 pandemic. The research problem is to understand howthese economic factors have affected the housing market, and the research objective is to analyze the activity of developers, building permits issued, investments started, and housing loans granted. The research methodology involves the analysis of data from various sources, including official statistics and reports from developers and investment funds. The research findings suggest that the decreased demand for housing loans has led to a significant decline in the allocation of new housing. However, the emergence of new major players, such as leading European and global investment funds, could provide opportunities for developers. The study concludes that caution is warranted in starting new construction activity and that the best performance in housing production in the transition period to 2021 is unlikely to be exceeded in the current or subsequent years. The implications of this study are that developers need to consider economic factors and market trends when making decisions about new construction and that investment funds may play an increasingly important role in the housing market.

The implementation of construction projects in Warsaw is associated with increasing difficulties in preparation, obtaining the relevant building permits and licences, partly due to the lack of water and sewage infrastructure and the inadequate management of rainwater in the city. All this leads to an increase in the cost of the construction projects undertaken. To illustrate a number of issues related to stormwater management in the city and the resulting problems, the study provides a number of different case studies, stylised facts and abductive conclusions to develop the best explanation for the existing problems. Specifically, the study presents the barriers to stormwater management in the city of Warsaw through an analysis of a hypothetical investment process (related to the Wawer Canal). The case studies analysed concern the deterioration of the “Bernardine Water” reservoir and the lack of appropriate investments in the Sluzewiecki Stream catchment, as well as a number of conflicting conditions in stormwater management in Warsaw. In contrast, examples of successful investments in stormwater management are also shown, e.g. Radex Park Marywilska, Stegny Południe settlement, Fort Bema settlement in Bemowo. In this way it is shown that with the right approach it is possible to carry out construction investments in water and wastewater infrastructure in an appropriate way, thus avoiding many stormwater management problems. The main conclusion of the study is that insufficient consideration of stormwater drainage issues in spatial planning will lead to further flooding and increasing water management problems.
