When designing multi-family buildings on plots that have not yet been developed, an important element is their location and its careful preparation. Pre-design analyses allow for the simulation of various solutions in order to select the most advantageous location of individual volumes and accompanying spaces. Appropriate arrangement of architecture and other land development functions helps to meet a number of formal and legal requirements, but also provides an opportunity for effective and comfortable living in a future multi-family development. The aim of the study is to show the possibilities offered by pre-design analyses in terms of sunlight and the organisation of space between buildings. Another goal is to outline the benefits of performing such analyses. Thanks to them, it is possible to use compromise in design solutions when it turns out that individual variants of a building location have better or worse properties, or certain conditions are mutually exclusive. The results were presented in the form of variants, presenting various land development solutions and relating directly to the previously conducted analyses. The analyses presented in the article allow for precise formulation of conclusions, and their selection is justified by the possibility of transparent and graphical interpretation of the algorithms performed during design.
