Abstract: An Innovation Center is a multifunctional facility that concentrates a wide range of functions such as business, research, production, education and culture. The issues of innovation centers architectural design are based on the creation of favorable conditions for scientific activity, communication and cooperation. Public space is a component of the multifunctional structure of the innovation center. It contributes to the emergence of interdisciplinary communities, increasing productivity in the creation and production of science-intensive products. The article considers the public space of the innovation center as a set of connected elements. The dependencies between the elements make it possible to create an environment that satisfies the various needs of users, taking into account the accessibility of the innovation centers functional areas. Based on the study of project documentation and field surveys, spatial schemes of 70 objects were made. The schemes indicate the elements of public space, the main ways of moving users, multi-light spaces and functional areas. Through a comprehensive analysis, horizontal and vertical connections of elements were identified. These include integration, blocking and dispersal. Then the methods of planar and multi-level architectural formation of public space were established. As a result, public space modules were obtained that provide variability and flexibility of the structure of the innovation center with the rational use of resources.
