The article presents research on the issue of shaping greenery in the 21st century in the context of modernist architecture. The studies include an analysis of the characteristic features of gardens designed during the modernist period and contemporary concepts, a case study of a green space project in Poznań, and the formulation, based on data, of a set of features which, according to the author of the article, should characterise a modern garden designed among modernist buildings. The comparisons, examples and conclusions refer to gardens designed within urban developments in private, semi-private and public spaces. The research emphasises the role of creating well-thought-out green space layouts that highlight the characteristic features of architectural objects, combining existing details with new ideas and creating environmentally friendly spaces. The information provided can serve as guidelines for the design of greenery in the context of modernist buildings for the development of future architectural concepts. The method of green space design presented in the article may also serve as inspiration when developing concepts for the creation of landscape interiors in the context of other styles.
