Ecopolis -  integrated, diverse and circular city model that ensures economic sustainability while staying carbon neutral through integration of circular systems and green energy, at highest standards of living.

With its strategic location,  the far eastern Federal District of the Russian Federation, Sakhalin, plays a progressively more important role in the global and regional economy. The international competition is launched to develop a concept for a new city in the southern part of the island, as an example of an innovative fast developing city in the Asia-Pacific region.

Together with Wowhaus, Nomura Research Institute, and the Scientific Research Institute of Ecology and Sustainable Management of Natural Resources, TSPA developed a concept for a new city model that ensures a transformation of economic growth, green energy integration and qualitative living.


We imagine a city integrated with the surrounding social, spatial and economic context. A city that lives together with the ocean, tapping into its culture through the proximity to the port and an active waterfront.

We imagine a city for the people who live it,, with vibrant public spaces and innovative architectures, embracing diverse urban typologies, social groups and public functions.

A city that takes advantage of the rich natural resources surrounding it while respecting them; that turns natural threats into values and virtuous circular systems to foster a prosperous and sustainable economy.


The expansion of the port of Korsakov will turn it into a global hub of maritime transit, providing new economic and commercial opportunities for Russia and the Sakhalin region. However the consequences of such transformation, hind potential risks of social conflicts, extensive use of environmental resources and uneven access to the port economies. To ensure the sustainable development of Ecopolis and the future port, they need to grow together and in accordance with the surrounding urban agglomeration. This proposal thrives for the spatial integration of Ecopolis with the existing urban fabric of Korsakov, with the topography of this territory, and with the ocean and its economies.

Ecopolis extends in accordance with the topographical and natural features of the territory. It develops on top of the hills, away from the steep slopes of the rivers. Its boundaries are porous and transparent, welcoming the surrounding forests into the urban fabric. Biodiversity corridors cross the city and complement the built environment with green public spaces. We propose a compact city that minimises soil consumption and maximises the spaces dedicated to nature, including productive forests, recreational parks and agriculture fields.


A vibrant city is the one embracing heterogeneous urban spaces, a multicultural society and diverse public functions.

We propose three main urban centers – Science, Culture and Business centers – located where the street network intensifies. Each of them presents unique urban typologies, architectures and functions.

Sakhalin Tech, with its laboratories and distributed research campus, takes place in the north center. This is an innovative research and industrial park for urban technologies, operating at the regional and national scale. It integrates institutes and residential buildings and productive facilities together to combine the research with high quality living spaces. At the heart of Ecopolis stands the cultural center, a dense neighborhood provided with vibrant public spaces and cultural facilities such as the public university and the community centre. High density multifunctional buildings integrate commercial services and residential functions and intensify the urban character of the city. The business center develops along the coast, close to the new cargo port. It provides the residential neighborhoods of the ecopolis with an access to the coast and activates the waterfront with workshops and small enterprises.

Sakhalin is an energy-intensive region. Currently flows of raw materials (oil, gas, natural resources) and manufactured products (food and fisheries) cross the island and are channeled through the port of Korsakov.

Ecopolis has the opportunity to capture and reuse these flows. We propose to convert the Island economy, currently based on the production of non renewable energy sources, into a value production chain through minimizing transportation of natural resources and maximizing waste upcycling; to  make a more sustainable use of the row and processed resources while fostering local economies.

We propose to connect the existing production flows in order to turn outputs into inputs of other processes.

A hybrid system of distributed facilities scattered in the city to collect and upcycle inorganic waste produced by the neighboring city of Korsakov and the port. This is combined with a centralized waste processing facility located in the north side of the area where organic waste is heated and converted into electricity.

Part of the output energy flows back to the city and partially feeds the production sites located in the north side of the project area, namely the wood-based materials manufacturing plant, the agroindustry park, and the wastewater treatment plant. These facilities supply the city with construction materials, food, and clean water, reducing the environmental and economic externalities of imported goods.
