The article substantiates the necessity of combining modern methods of underground urban planning in areas of special urban planning value, which include transport interchanges and their adjacent territories. Techniques for the rational organization of service facilities and prospects for the development of accompanying functional areas are formulates. A modern multi-functional complex as part of a transport interchange hubs requires the use of new means of forming the architectural environment: external and internal organization of underground space. The purpose of the publication is to argue for the optimization of the development of public service facilities of transport interchanges due to the organization of underground spaces and to determine the main advantages of rationality. Analysis of the Utrecht and Berlin stations as examples of European experience in the operation and development of transport hubs demonstrates the main advantages of rationality in the organization of underground spaces. The concept, which reorganizes transfer points into small businesses and shopping centers, integrates them into underground spaces: places for holding exhibitions and business events, conference halls. Effective using of land resources helps to free up the territory for pedestrian areas. Using of modern technologies in the field of energy efficiency and ecology correspond to the direction of sustainable development; separation of traffic and pedestrian flows, organization of the shortest paths to various types of transport and evacuation are beneficial when used as a shelter; economic efficiency increases the urban value of the territory. The topic of conceptual design, introduced at the Department of Architectural Environment Design in Kyiv National University of Construction and Architecture when developing a highly urbanized transport hub in accordance with the concept of the location of high-rise buildings in Kyiv, approved by the Academy of Architecture of Ukraine.
