Eco Space - structural space of the city, determinesand formed by the quality of the relationship between separate entity and thecity as organismic –integral system (city - spatial expression of the existenceof organisms) with the environment. It Involves the regeneration of the city,the exchange of energy and its recovery, equipment and maintenance of urbansustainability and autonomy. Development opportunity for the city as aself-sufficient system is environmental space integration as a structuralcomponent of the urban fabric.

I see the future development of urbanism asprogressive understanding of the city as an integral system, spatial expressionof existence, interaction of parts in the whole what will require amulti-disciplinary tools. The idea of ​​sustainable design should be expressed in supporting the viability, cultivatingand stimulating constituent spaces ofurban fabric where all elements ought to be strictly differentiated andcorrelated.

  1) Space of exchange (exchange at all levels, informationspace, economic elements)
Investment and profit. / Exchange and trading space. Necessary toencourage interaction between local businesses, communities, to develop a"space of exchanges."/ To provide new jobs and provide incentives forthe private initiatives development toencourage the emergence of new services./ Information framework stimulation. Activationthe “space of knowledge” and “know-how exchanges”.

  2) Material-spatial environment.
a) Artificially-constructed. The frame and fabric ofthe city. Provision of connectivity, density, intensification of territorialresources. / Flows. opportunities for mobility / Polycentric city. / QA of theurban environment. Video ecology / A variety of spaces and space capabilities.
b) Natural environment. Climate and weather. Shadow / Water / Soil / Greenspaces.

  3) Eco space . Renewable energy/ Rain watercollectors / Materials recycling / Sound, photo pollutions / Green facades/Living machines

  4) Social space. Community / Safety / Training. Attracting attention / Biophilia

Rostov-on-Don is a typical image of Russian citynowadays with such problems as car primacy, human scale degeneration,fragmentation, dilapidated environment,
losses of the "spirit of place" and also of safety. Russian architecturalpractice has fragmentary orientation in these fields and has no concept andidea of ​​theecological space of the city as an integral part of its structure. This approach aggravates thesituation and doesn’t solve problems in general. The idea of ​​the project involves spatial modeldesign of sustainable urban local interior as a starting point of the sequentialregeneration of the urban fabric as a “Whole”. Key principles of architecturalpractice turn from static object design to cooperation with dynamically evolving systems of relations.

Three major hubs wereidentified in recycled area which forms the basis of the cell stimulation ofthe urban fabric. Each community is threaded on a rapid transit line. Idea ofgreen transport utilization realized inbounds of communities. A paradigm shiftfrom “the city for the cars” to the “city for the people” as ​​a compact walking city accomplished on a large scalealternative of pedestrian routes.

First hub, “theatrical quarter”, combines city center withwaterfront with broad pedestrian thoroughfare; includes both a green terrace complex equipped with three types ofcommunication: stairs, ramps and escalators for accessibility in the builtenvironment; and the new bridge interconnecting structure to the left bank."The Green Mile" is transformed into a pedestrian overpass/squarewhich extends at the level of a second green artery passing horizontallythrough the top mark of the rugged topography of the waterfront area. These peculiaritieswould impress walkers by the variety of multilevel routes and opportunities toexplore the space. On the base level of the area placed reservoirs for collectingrainwater used for technical needs and embankment aeration.
Multifunctional spaces of adjoined complexes on theeastern side not only stimulate the social life and communication betweentenants but help in solving a number of issues of everyday life. For example,the presence of the common areas for children (games room) allows creating akind of "home” kindergartens to significantly reduce costs for families tocare after children on weekdays.

Second hub is cultural and educational cluster. It isbased on the adaptation of the environment of the former factory. There were used methods of theatrical and new “information -navigation landscape”integration to make former gray space a kind of "artistic quarter" thatwill transmit animating impulse to adjacent neighborhoods and run mechanism oftheir transformation into a comfortable and scenic urban environment. The newspace-behavioral scenario assumes porous borders of culture-educational cluster.That assumes the design to be not isolated but open to the city system.

The most part of the Third hub converted into boutiquecomplex. Roofs are adapted to recreational areas and public gardens. Museum ofTechnology, former bus plant, is located near to the new LRT station and transportnode. At the museum will be presented not only the types of transport but and next-generationtechnologies of environmental sanitation and alternative forms of energy. Ecoparkadjoins at the south-east side to the museum and involves the idea of ​​industrial tourism to attract socialattention to environmental issues. Hard river edge was transformed intoself-purifying landscape (natural lagunage and phyto-purification). Eye-contactwith landscape is facilitated with hiking paths and bicycle routes. It alsorenews the notion of fish farming in artificial ponds, and the system of urbangardens developed further to the idea of vertical farms, which can beintegrated into the urban tissue.

Conceptual space model was based on the priority ofthe pedestrian traffic and principles of the video ecology. Buildings are onsupport pillars forming comfortable integrated shaded places, or ground floorsare given over to cafes, shops, offices and storefronts facing the street. Thecoastal driveway is assigned for car traffic, from above is the elevated road,light rail line. At the same time the flow of transport and pedestrians arelaid in different spatial levels: communication channels, passages, pedestrianbridges, overpasses in different levels - pierce through thewhole space forming a multi-layered fractal framework of streets, enrichingenvironmental model with new spatial capabilities, providing spatialvariability of choice.

Wide range of public spaces was formulated on thebasis of the conception of so-called “third place («1st place" - home, «2nd"- work). Icon of the "third place" is a city café, local site for ​​communication, and working place forcreative professionals. It puts into reality the principles of mixed-useactivities, of integration of various strata of population, and of co-working and collaboration between professionals in different fields.Public spaces can also be used as a venue for business meetings, kind of newoffices.

Saturation, as a redundancyof multi-functional public spaces supply for human and social development,requires activation of community from itself. Self-organisedgroups of citizens can proactively arrange a variety of actions, developmentcenters, gaming space, etc. This space of redundancy of opportunities expandsthe horizons of co-creation and motivates community to get involved in the evaluativeevents in the city.
