This thesis explores the development of modular and parametrically configurable rooms for prefabricated construction, with the application of the SolidWorks 2020 computer program for the creation of an accompanying 3D model. In the context of increasing demands for faster and more efficient construction, prefabricated construction is a modern approach that enables serial production of building modules in controlled factory conditions, which significantly reduces construction time and the negative impact of external factors. The paper analyses the basic principles of modular design, as well as the advantages arising from the application of standardization and modularization in the construction industry. On the example of the concept of a prefabricated bathroom, the process of modularization of the structure and equipment is described in detail, which appear in two basic configurations: the first, which is simpler and more compact, and the second, which is more spacious, but more complex. Both configurations allow the user to customize various elements, such as door and window position, shower dimensions, the presence of a niche, colour and dimension of tiles, and the type and shape of sanitary items. In the central part of the paper, the development of a computer (parametric) model of a prefabricated bathroom is described. Parameterization of the model allows easy modification of the geometry of the prefabricated room by changing the values of the variables, thus generating a large number of variants without the need for remodelling. Special emphasis is placed on the creation of a user interface that allows intuitive configuration of the model according to the given requirements. In the final part of the paper, an analysis of the efficiency of the developed system was carried out and possibilities for further improvements were proposed. The paper provides guidelines for the development of similar configurable systems and highlights the potential of parametric design as a tool for the modernization of the construction industry and related sectors, in which flexibility, efficiency and serial adaptation of products to end users are important.
