Abstract.The purpose of the author's research is to determine the actual content of sustainable architectural design for suburban residential development. In accordance with the methodology of area sustainable development the traditional architectural design according to the rules and regulations is completed with additional approaches and methods. As a result, methods of bio-positive design of buildings have been studied and defined, including: the principle of planning transformations, the use of environmentally friendly, local building materials and design concepts, energy-efficient architectural design, the use of alternative energy in building operation, the design of the energy intake and accumulationsystems, the architectural and landscape design that ensures stable functioning of autonomous, sustainable biosystems on the site, nonwaste functioning of architectural objects, introduction of waste disposal systems in the project.

The article deals with the strategy of the architectural and urban planning formation of bioecoagrocentres in the Middle Volga Region and city-farming as the forms of public employment in cities, commuter belt and countryside, justifies the system of Universal design that is innovative for the Russian Federation. The hypothesis about the actuality of senior age labour recourses’ engagement is made in the context of the population ageing problems, lack of qualified labour resources and general out migration from the countryside. It is proved that the planning of innovative, highly comfortable agrocentres environment (including the cities) may be necessary at all major target levels, i.e. urban planning, architectural, objective-spatial on the basis of the Universal design principles as a project tool. The gradual realization of environmental projects is planned. Correspondence with the principles of Universal design in this case is the element of environment accessibility quality control for all the categories of users including the mobility impaired ones.

The articletouches upon the issues of information spaces formation in the environment of large Russian cities exemplified by Samara. The taxonomy of city information spaces with the consequent placement of the integrated sites of information distribution characteristic for Smart City, i.e. infoboxes, is determined. The main criteria of an urban environment informative value are formulated. The results of architectural and urban planning research of the urban environment fragments with the consequent experimental projecting are given.

The current aspects of the formation of the sociospatial concept of a Healthy city are considered. The basis of this concept is being studied the framework of an accessible urban environment. Based on modern information technologies of design, operation and reconstruction of elements of the urban environment, the advantages of creating and using digital twins of an accessible urban environment are shown. The possibilities of modern city monitoring systems are analyzed. An algorithm for monitoring the accessibility of the urban environment is proposed to provide cities with information about the operation of the components of the system and intelligence for quick reactions and decision-making in various situations.

The article examines the problems that the station areas of the largest cities face in the process of their development. The article reveals such concepts as the landscape-recreational frame of the territory, its functions, the search for possible reserves for spatial development and improving the quality of the ecology of the environment. Natural and anthropogenic factors influencing the formation and operation of the frame elements are analyzed.
