This paper outlines the outcomes of the deployment of selected heuristic methods in the initial stages of the design process for a modernised public space. The process was carried out in accordance with the objective of adapting the space to contemporary user needs and environmental conditions. The research is situated within the broader context of exploring solutions for shaping public spaces inspired by nature, with the aim of contributing to the enhancement of both the psychophysical condition of humans and the state of the environment. The Research through Design (RtD) methodology presented in this article is based on the use of two, different invention methods: ‘brainstorming’ (brainstorming) and the Theory of Inventive Problem Solving (TRIZ) (in Russian: Teoriya Resheniya Isobretatelskikh Zadatch). In addition, the Design Thinking (DT) method was employed at the stage of data collection regarding user preferences. The subject of this research is a specific building object, which simultaneously represents and exemplifies the city space. In consideration of the project's assumptions, the principal objectives for the station's modernisation proved to be identical when employing both inventive techniques. An investigation into the potential for the modernisation of the bus station into a model public space through the utilisation of Nature based Solutions (NbS) and the advancement of a healthy lifestyle (wellbeing design) will facilitate the formulation of more comprehensive recommendations for the design of contemporary public spaces.
