Abstract. Growth of population affects the increase in demand for
development of new areas. The article discusses current problems and trends
in the development of vertical cities of the future. The last decade has seen
the consolidation of the urban environment and the transition of urban
planning from horizontal to vertical. The structure of future vertical cities
minimizes land use and contributes to solving environmental problems and
de-urbanization. The authors analyze the origin of «utopia» word and its
meaning in the concepts of utopian cities since ancient times. The formation
of a comfortable vertical city is a utopia aimed at turning it into the reality
of the future. A general analysis of space-planning and architectural
solutions of modern concepts helped to formulate the basic principles of
creating a vertical city. The identified criteria of the architectural space will
allow humanity to live in a comfortable environment, including the period
of forced critical conditions. During the research, we presented a hypothesis
of the emergence of vertical cities in the world and in Russia. The study can
become the basis for forecasting the processes of urbanization and de-
urbanization, also as a concept creation for the development of a sustainable
model of the future vertical city.
Keywords. Vertical city, utopia, sustainable urbanism, architecture,
overpopulation, urban planning structure.
1 Introduction
The problem of overpopulation and increasing population density in cities is particularly
relevant in the last decade. According to the UN, there will be about 10 billion people on the
planet by 2050. Large cities need to adapt to the rapid pace of land development. Nature is
losing the war against urbanization, this affects climate change, the purity of air, water
resources, soils and, in general, the violation of the ecological state of the environment [1].
The psychological aggravation of all spheres of human life led to isolation, to the limitation
of life processes, to the desire to create a more reliable and comfortable living environment
around oneself in the 2020 pandemic [2]. The restructuring of the priorities of mass services
is taking place on new values: safety, longevity, comfort, ecological environment, culture,
reduction of global risks and active visual perception of the environment by humans. Massive
development of «consumer» planning creates uncomfortable, unsafe and unhealthy cities.
The projects of architects and researchers have always contained ideas for the development
and reclamation of new lands, work with extreme climatic zones and relief, with the elements
of earth, water and air. Interest in architectural fantasies and concepts of future cities did not

fade away, it was a constant catalyst for the creation of a limitless number of ideas for everyday
life in the urban space. Architectural concepts and research on future cities were in the works
of Charles Fourier, Ebenezer Howard, Le Corbusier, Yona Friedman, Buckminster Fuller,
Frank Lloyd Wright. In the 21st century, Luca Curci Architects is actively developing projects
for the vertical arrangement of cities. Vincent Callebaut puts forward many concepts for future
cities with an ecological aspect. John Wardle Architects and Stefano Boscuitti showcase the
Multiplicity project. This is the vertical development of the existing city by the end of the 21st
century. The eVolo 2021 Skyscraper Competition, The SKYHIVE 2020 Skyscraper and
various competitions for creating master plans for new cities are the driving force behind the
creation of future vertical cities and solving global problems.
The modern world is not like the one that past generations dreamed of. After
industrialization, the place was taken by urbanization, megalopolises were actively built. The
space-planning structure of cities developed horizontally, the height of buildings and the
number of floors increased [3].
Utopia appears in all concepts and forecasts of the future world that will make our life
more comfortable [4-6]. These are often idealized projects that contain the fears and hopes
of the society. Many researchers and architects were involved in the development of vertical
cities. Vertical construction is a reality. Future vertical cities are utopia. What is the
difference between isolated skyscrapers and vertical cities?
The concept of a vertical city means that it is a set of vertical buildings with a developed
infrastructure [7, 8]. It is a whole ecosystem in the air environment, which is many times
larger than a building spot on earth. Each person must have their own living cell, adaptable
and safe in a vertical city [9-11]. Lack of leisure drives a person to a vicious circle between
work and home; therefore, it is important to create a compact planning structure with public
places. As a result, the formation of the architecture of the future vertical city [12-14] and
conceptual ideas for residential complexes should contribute to solving environmental
problems and de-urbanization. Projects should combine a model of high sustainability and
high-quality living standards of the population [15]. Active development of innovative
technologies in building materials [16, 17], design features of high-rise buildings [18, 19], in
the field of landscaping facades [20, 21] contributes to the expansion and systematization of
the vision of future vertical cities [22].
2 Materials and methods
The materials of this study are based on theoretical works and projects of architects,
philosophers, and researchers. Since ancient times, thinkers and philosophers have been
trying to envision an ideal life. Urban planning and architecture were also a base for such
concepts. Babel Tower embodies the connection with the Almighty, the imagined world of
Atlantis – known from Plato’s dialogues – is the eighth tetralogy, telling about the problems
of an ideal city with centric planning schemes and defined outskirts. Hippodamus of Miletus
developed an urban planning principle which was based on rectangular residential blocks and
a defined grid of streets. This principle was named grid plan and has been widely used as a
base for numerous cities. Vedutas of the mid – 15th century are an embodiment of the views
about ideal cities. In 1516, Thomas More first defined the concept of utopia. According to
More, Utopia is a country that existed in the past or exists now. This country is located on an
island and the humanity has not reached it yet, even though it is theoretically possible. In his
work, Thomas More brought together the thoughts of philosophers of the past, for whom a
harmonious world was a union of people and gods.
In the article «Notes on Utopia, the City, and Architecture», Antoine Picon, the professor
of the history of architecture and technology, examined the question of how urban and
architectural projects were presented by utopian thinkers. Antoine Picon writes that utopia,
urbanism, and architecture are intertwined, creating many possible scenarios [4]. It was the city
that was the space for transformations. During the Renaissance, many projects of ideal cities
were created. In the 18th century, architectural utopias were developed while being closely
connected to social processes. The ideal urban structure, according to its authors, is based on
ideal architectural forms. The utopianists were convinced that the creation of an ideal world
would be impossible without a change. Many projects of perfect utopian cities were created to
remain on paper, unrealized; such projects received a name «visionary architecture». These
fantasy worlds were unfeasible because of technical restrictions of the time or because they
contradicted the political views of the state. In the 19th century, utopia took on the effect of
reality and detail; new concepts of ideal cities are based on facts and scientific objectivity. There
were less and less unexplored places left on the map of the world, less and less places to idealize
the unexplored. Robert Owen and Charles Fourier, the creators of ideal cities, presented the
concepts of small low-rise settlements. In 1833, Chicago appeared on the map. The city was
based on the grid plan, and its first skyscraper was built in 1885. In 1898, Ebenezer Howard
introduced «Garden Cities» which references Plato's utopian planning of Atlantis.
At the beginning of the 20th century, the world faced various cataclysms. Hoping that
architecture can bring salvation, the architects were developing new cities in the spirit of utopian
ideals. Some were based on the development of technology, some – on the development of new
lands, and others were meant to solve social issues. Antonio Sant'Elia presented the futuristic
concept of «La Città Nuova», which was heavily based on the use of vertical dimension. It
included such innovative elements as skyscrapers, bridges, and cable cars.
Le Corbusier believed that with the rational planning of the city, it was possible to solve
social issues by reduing the time spent on reaching the destination – e.g., shortening the
period of construction could lead to the industrialization of housing [4]. He argued that it is
vital to modernize the construction process, stepping forward from outdated methods. Le
Corbusier created experimental utopian concepts with his own vision of ideal cities: «Plan
Voisin», an idea for a city center with vertical construction plan and green gardens; «Ville
Radieuse» – a plan that lacked the human scale and the elements of nature and which became
an inspiration for many cities.
Le Corbusier actively developed the principles of urban planning and mass housing
construction. His utopian thoughts contain the idea that there should be no mixing of different
functions in the city. One day, the plan of the city of Chandigarh was brought to life, where
«Utopia» was adapted to the context of the area [5]. In 1932, in his concept of «Broadacre
City», Frank Lloyd Wright described an idea of an aerator, an unmanned transport accessible
for every family. Numerous futuristic concepts perfectly reflect the view of utopia –
impeccable worlds with innovative ideas of life within different elements –under or on the
ground, under the water, in the air, and in space. Utopia was a mean of self-expression, where
many of the ideas included a wide variety of «vertical cities» of the future.
In the 21st century, utopia is the discovery of new possibilities in the present. Indeed, all
the concepts of the future that architects and researchers envision seem to be utopian:
automated cities, aerial streets for self-piloting transport, waste-free construction. Utopian
projects shape our view for the future; create the contours of space and plot lines.
Practical experience and regulatory documents impose restrictions and adjustments when
detailing the space [6].
In the course of the research, the method of comparative analysis of architectural projects
of the future high-rise buildings was used. The idealization method is used to derive the
hypothesis for vertical cities.
The examples of utopia on the verge of reality, innovative projects of foreign architects
created over the past few years are presented in Table.

Table. Future city projects.
The projects are considered as residential units of a vertical city. The comparison of
objects is based on the following criteria: the placement of objects in an urban environment,
their shape, and planning structure.
1. The placement of the objects in an urban environment: objects in an urban environment
can consist either of separate units in an existing structure, or they can be formed by several
objects and creating the structure of a vertical city.
For the sustainable growth of the cities, a development of the scenarios of response to
various disasters and pandemics is required [7].
2. The structure is based on simple streamlined shapes. The wind resistance of the
structure, the dependence of the wind load on the air density, the energy consumption of
buildings should be taken into consideration for creating an energy-efficient form for the
optimal density of a sustainable city [12, 19]. It is worth noting that the construction of the
future will rely on the emergence of new materials and technologies for waste-free production
[16]. For example, «Epidemic Babel» is a project of a medical skyscraper designed to quickly
respond to pandemics by assembling the object's framework.
Architecture is a way of visual consumption. The architecture of high-rise buildings is
defined by the internal framework of the building and its functionality, and it is also important
for it to reflect the identity of its surrounding area [8, 14]. The architectural image of the objects
«Verticality» and «Epidemic Babel» is created by the modular structural network of the facade.
3. Planning structure. The internal spaces of the planning structure should allow
functional flexibility for a quick adaptation to changing circumstances.
The aesthetic appearance and mobility of the building's planning are connected to the
creation of unique facade and shape [9, 11]. The project «Metallic Villadrone» imagines a
city in 2100 with flying multifunctional capsules serving as living units. Conservation of
nature with the help of concise planning solutions is presented by «Post-Pandemic City of
Tomorrow» and «The Link» as a response to the environmental problems.
3 Results
The analysis of volume-planning and the architectural features of vertical construction
revealed a number of trends in the projects created in recent years.
- Sustainable urbanism is an integral part in creating future paradigms of vertical cities [1].
The importance of strategic planning of high-rise construction is determined by the
planning structure, the population density of the city, functional diversity, transport
structures, and landscaping.
- The height of the existing skyscrapers and the innovative technologies used during their
creation are outstanding. It is important to develop the optimal height for future vertical cities,
whether there will be dominants or all objects will have the same number of floors. The height
of the building is related to the population density. A vertical city is not a single building, but
a system of high-rise structures. Architecture and its visual perception is one of the key
aspects of human existence in vertical cities. Human scale is an important factor for
consideration while creating lower floors in high-rise buildings.
- The formation and the planning structure of high-rise construction should be adapted to
its aerodynamic needs. Vertical cities involve innovative technologies, renewable energy
sources, and water-saving systems.
In high-rise buildings, the area of the facade allows for the use of solar energy and the
integration of photovoltaic systems [17].
- Functional content of the building. It is important to create the paths for the development
of a future vertical city and take into account many influence factors [22].
A high-rise building may be monofunctional: it can consist of a residential area with
public spaces, while the first floors are used by commercial entities. The visual appearance

of the building affects the functional features of the space, and may also bring to life the
concept of a «vertical street».
- Healthy environment. The presence of landscaping is important for the surrounding
areas of vertical complexes. These requirements may be attained by the use of facade
landscaping and green public spaces.
Such «oases» in residential buildings satisfy the social functions by supporting mental
health and reduce the level of stress [21]. It is planned that landscaping should be
implemented in 30-50% of the densely populated areas of vertical cities [20]. Green spaces
need to be organically intertwined with the structure of the building. Healthy cities should
take into account the consequences of COVID-19 while adapting the spaces.
- Transport and communication framework. The basis of the urban structure is streets,
pedestrian accessibility and transport infrastructure, which are wide enough for the
movement of pedestrians and vehicles, including those specialized for vertical
communications. A well-developed pedestrian network involves not only streets, but also
bridges, and reduces the time spent to reach a destination. It is important to analyze the jobs
and ways of employment of the future and allow the possibility of a mass switch to remote
work. It is impossible to know whether modern cities will use the systems we imagine.
Perhaps, the city development indeed will go in a vertical direction, «improving» and
adapting modern skyscrapers and designing vertical streets. With possible appearance of
accessible unmanned vehicles leading to the new ways of parking, the new limits of the
building heights will become an important question to consider. A residential unit may
become a flying object which can change its position in the frame of a high-rise building.
- A high-quality urban environment creates a solution of a seamless coexistence of the
present buildings and those of the future. Vertical complexes should be integrated into
context of the area.
A well-organized use of vertical spaces inside and outside of the buildings will allow
humanity to live in a comfortable environment. The main components of the architecture of
the future are safety and adaptability, equality and acceleration of the development of new
construction trends.
The increase in population density on the planet and the shortage of land, ecological issues
and climate change are determining numerous concepts for the vertical cities of the future. It
is important to consider the changes that will take place in the environment and how will the
future cities respond to such changes. The world is already in a transition between the past
and the future, when the trends of high-rise construction are establishing and evolving. As
the cities in developed countries are becoming more densely populated, they begin to actively
develop their high-rise architecture.
Pandemic and the fight against it became one of the main challenges of the 21st century.
There is a need for cities that provide safety from virus and infectious outbreaks [2]. The ability
to separate human flows and allow safe social isolation with an easy access to health services
are the important aspects that should be taken into consideration when designing a city.
The trend of developed cities will be a horizontal expansion with an active development of
vertical dominants [3]. It can be assumed that the first vertical city is expected to appear in one
of the developed countries in the 21st century. While such projects have been designed by
foreign architects for many years, the limits of economic efficiency, structural components,
climate or lacking innovative solutions create some difficulties for the development. The first
country to build a vertical city will do so due to the problem of land shortage or
overpopulation, with the innovative breakthrough being the reaction to the problems.
A Russian vertical city will remain a utopia for as long as there are enough land resources
for the horizontal development of the cities. There is a surplus in the information sphere and
architecture resulting in a trend towards clean facades and simple forms. Russia is a
developed country with a range of high-rise architecture including residential buildings; the
project of a Russian vertical city as a separate complex is a utopian project aimed at
improving everyday life. However, an in-depth research and analysis of the economic
efficiency of the object is needed with the understanding of how the climatic features of the
country and the terrain will affect the structure of the object.
As a result, the projects will combine a high-sustainability model for a densely populated
area aimed at creating a hybrid city with zero energy consumption and interconnected spaces.
4 Discussion
The study examines the tendencies of the utopia ideas of architects, urban planners and
philosophers since ancient times. Concepts were transformed and filled with idealistic ideas,
solving the problems of their time. In the future, they took on specific outlines in the heads
of subsequent generations. Some of the ideas have been successfully implemented, but
history has made its own adjustments.
After studying the theoretical base, there was a demand for a comparative analysis of
modern high-rise buildings and in determining the general trends in construction. Analysis
of space-planning and architectural solutions helped to formulate the main directions in the
development of a vertical city through projects in recent years. The hypothesis showed a
possible vector of thoughts about what would contribute to the construction of a separate
vertical city.
The significance of the topic based on the fact that the concepts of vertical cities are aimed
at improving the quality of the space around us. The architecture is characterized by
continuity from the surrounding world. Factors such as human behavior and emotions,
sociocultural interactions, and consumption economics influence the formation of the urban
environment.
Problems environmental disasters do not occur for no reason; the earth needs to be
liberated. This is a catalyst in the development of vertical cities; new approaches appear in
the formation and constructive component of objects.
5 Conclusion
1. The study shows that since ancient times, humanity has been drawn to the sky, and upward
movement in architecture is inevitable. The concept of a vertical city is not a utopia and a
beautiful picture, but a compilation of real processes for a better life, which humanity can
only organize by joint efforts. However, only time will tell whether the architects' ideas are
utopian or realistic.
Human-environmental interactions should not be swallowed up by technocentricity. It is
important that the city remains empathic and the person remains a priority [13].
2. A sustainable and healthy vertical city is a city that improves the environment and
social environment, complements all life functions, is safe, and uses modern technologies to
control the quality of space [10, 15].
It is important to note that the identified criteria for the architectural space of vertical
cities will allow humanity to live in a comfortable environment, even during the period of
forced critical conditions and cataclysms.
3. The following trends are highlighted in the development of vertical construction:
- sustainable urbanism;
- optimal altitude for a given location;
- dependence of shape and planning on external influences;
- the correct calculation of the frame and the use of innovative technologies [18];
- functional filling of the building with everything that is necessary for the human life cycle;

of the building affects the functional features of the space, and may also bring to life the
concept of a «vertical street».
- Healthy environment. The presence of landscaping is important for the surrounding
areas of vertical complexes. These requirements may be attained by the use of facade
landscaping and green public spaces.
Such «oases» in residential buildings satisfy the social functions by supporting mental
health and reduce the level of stress [21]. It is planned that landscaping should be
implemented in 30-50% of the densely populated areas of vertical cities [20]. Green spaces
need to be organically intertwined with the structure of the building. Healthy cities should
take into account the consequences of COVID-19 while adapting the spaces.
- Transport and communication framework. The basis of the urban structure is streets,
pedestrian accessibility and transport infrastructure, which are wide enough for the
movement of pedestrians and vehicles, including those specialized for vertical
communications. A well-developed pedestrian network involves not only streets, but also
bridges, and reduces the time spent to reach a destination. It is important to analyze the jobs
and ways of employment of the future and allow the possibility of a mass switch to remote
work. It is impossible to know whether modern cities will use the systems we imagine.
Perhaps, the city development indeed will go in a vertical direction, «improving» and
adapting modern skyscrapers and designing vertical streets. With possible appearance of
accessible unmanned vehicles leading to the new ways of parking, the new limits of the
building heights will become an important question to consider. A residential unit may
become a flying object which can change its position in the frame of a high-rise building.
- A high-quality urban environment creates a solution of a seamless coexistence of the
present buildings and those of the future. Vertical complexes should be integrated into
context of the area.
A well-organized use of vertical spaces inside and outside of the buildings will allow
humanity to live in a comfortable environment. The main components of the architecture of
the future are safety and adaptability, equality and acceleration of the development of new
construction trends.
The increase in population density on the planet and the shortage of land, ecological issues
and climate change are determining numerous concepts for the vertical cities of the future. It
is important to consider the changes that will take place in the environment and how will the
future cities respond to such changes. The world is already in a transition between the past
and the future, when the trends of high-rise construction are establishing and evolving. As
the cities in developed countries are becoming more densely populated, they begin to actively
develop their high-rise architecture.
Pandemic and the fight against it became one of the main challenges of the 21st century.
There is a need for cities that provide safety from virus and infectious outbreaks [2]. The ability
to separate human flows and allow safe social isolation with an easy access to health services
are the important aspects that should be taken into consideration when designing a city.
The trend of developed cities will be a horizontal expansion with an active development of
vertical dominants [3]. It can be assumed that the first vertical city is expected to appear in one
of the developed countries in the 21st century. While such projects have been designed by
foreign architects for many years, the limits of economic efficiency, structural components,
climate or lacking innovative solutions create some difficulties for the development. The first
country to build a vertical city will do so due to the problem of land shortage or
overpopulation, with the innovative breakthrough being the reaction to the problems.
A Russian vertical city will remain a utopia for as long as there are enough land resources
for the horizontal development of the cities. There is a surplus in the information sphere and
architecture resulting in a trend towards clean facades and simple forms. Russia is a
developed country with a range of high-rise architecture including residential buildings; the
project of a Russian vertical city as a separate complex is a utopian project aimed at
improving everyday life. However, an in-depth research and analysis of the economic
efficiency of the object is needed with the understanding of how the climatic features of the
country and the terrain will affect the structure of the object.
As a result, the projects will combine a high-sustainability model for a densely populated
area aimed at creating a hybrid city with zero energy consumption and interconnected spaces.
4 Discussion
The study examines the tendencies of the utopia ideas of architects, urban planners and
philosophers since ancient times. Concepts were transformed and filled with idealistic ideas,
solving the problems of their time. In the future, they took on specific outlines in the heads
of subsequent generations. Some of the ideas have been successfully implemented, but
history has made its own adjustments.
After studying the theoretical base, there was a demand for a comparative analysis of
modern high-rise buildings and in determining the general trends in construction. Analysis
of space-planning and architectural solutions helped to formulate the main directions in the
development of a vertical city through projects in recent years. The hypothesis showed a
possible vector of thoughts about what would contribute to the construction of a separate
vertical city.
The significance of the topic based on the fact that the concepts of vertical cities are aimed
at improving the quality of the space around us. The architecture is characterized by
continuity from the surrounding world. Factors such as human behavior and emotions,
sociocultural interactions, and consumption economics influence the formation of the urban
environment.
Problems environmental disasters do not occur for no reason; the earth needs to be
liberated. This is a catalyst in the development of vertical cities; new approaches appear in
the formation and constructive component of objects.
5 Conclusion
1. The study shows that since ancient times, humanity has been drawn to the sky, and upward
movement in architecture is inevitable. The concept of a vertical city is not a utopia and a
beautiful picture, but a compilation of real processes for a better life, which humanity can
only organize by joint efforts. However, only time will tell whether the architects' ideas are
utopian or realistic.
Human-environmental interactions should not be swallowed up by technocentricity. It is
important that the city remains empathic and the person remains a priority [13].
2. A sustainable and healthy vertical city is a city that improves the environment and
social environment, complements all life functions, is safe, and uses modern technologies to
control the quality of space [10, 15].
It is important to note that the identified criteria for the architectural space of vertical
cities will allow humanity to live in a comfortable environment, even during the period of
forced critical conditions and cataclysms.
3. The following trends are highlighted in the development of vertical construction:
- sustainable urbanism;
- optimal altitude for a given location;
- dependence of shape and planning on external influences;
- the correct calculation of the frame and the use of innovative technologies [18];
- functional filling of the building with everything that is necessary for the human life cycle;

- high-quality urban environment for all population groups and ages, including for people
with limited mobility;
- modernized transport and communication framework.
4. The results of this work can be used to predict the processes of urbanization and de-
urbanization in the world. The use of materials from this study will help in developing a
concept for the development of a sustainable model of the future vertical city.
For further work, it is necessary to study the trends of modern building technologies, to
develop optimal volume-planning models of vertical cities. Investigate in detail the
ecological and psychological aspects of such structures on humans and the environment.
