The article presents the results of the analysis and systematization of proposals in the direction of the assessment of design solutions and the identification of additional opportunities for typical design when applying frame industrialized building systems in residential construction. The problem of architectural style in typical design is one of the most acute problems of creativity of modern architects. In the engineering and technical assessment of building structures and building systems characterized by interchangeability, certain technical indicators that characterize the level of combinability or variability of the building may be used. It is proposed to use two indicators: the coefficient of absolute diversity and the coefficient of relative diversity, to evaluate the efficiency of design and the efficiency of interchangeability of elements. Due to the results of the research, the use of prefabricated frame for public and auxiliary industrial buildings in housing, is of particular interest and has certain prospects. And because of the urgent need to increase the volume of housing construction and the need to revive domestic industrialized construction, it is also extremely relevant. The material and technical base of the prefabricated industry and the scientific and technical potential of the 1.020 interspecific frame are best suited for this purpose. Sharing this frame with, for example, wall panels designed for large-panel residential construction offers great opportunities for creative search and improvement of architectural and styling solutions.
