Collective Creativity and Complexity in Urban Laboratories: El Campo de Cebada

: Cities are complex systems requiring urban design models that balance order and disorder. Collective creativity initiatives engage citizens in these processes, empowering bottom-up approaches that prioritize people and social well-being within urban development. This paper investigates an ‘Urban Laboratory’ as a case study, examining the potential of collective creativity to address urban complexity. The successful and ongoing project ‘El Campo de Cebada’ in Madrid, Spain, demonstrates how a community transformed a vacant lot into a vibrant social hub. The phases of this study include case selection, data collection, data analysis, and presentation of the results. This study identifies key enabling factors, including agents, management, social dynamics, infrastructure, and actions. These insights offer a methodological framework for designing future collaborative, resilient, and inclusive urban spaces, addressing the complex needs of communities within our cities.


Introduction
Contemporary cities are complex and face a range of challenges, from inequality to a lack of sustainability.However, urban models based on traditional hierarchies and processes do not adequately address these problems.Instead, the cities of the future could be built through new strategies, considering today's complexity and challenges.In this sense, there seems to be some consensus on the importance of collaboration and citizen participation to achieve more liveable, sustainable, and equitable cities.In this regard, the Sustainable Development Goals, specifically SDG11 [1]-sustainable cities and communities-aim to make cities more inclusive, resilient, safe, and sustainable.Looking towards 2030, the United Nations identifies three major issues that cities must address: guaranteeing universal access to public spaces, increasing citizen involvement in urban governance, and intensifying efforts towards sustainable urban development.
'Social collective behaviour' builds biological communities, digital networks, and cities indistinctly, first to survive and lately for the common good through profit-based exchange.'Swarm intelligence' is based on emerging systems that could become brilliant innovators and adapt better to changes than any other model with rigid hierarchies.They are network structures distributed through self-organised systems that build their complex itineraries with bottom-up logic.In this sense, Michael Hardt and Antonio Negri [55] assert that "likewise, a network without a centre that commands, those who only think according to traditional models believe that there is no organisation at all and only see spontaneity and anarchies. . .but when looking from within the network, one could observe that there is an organisation, rationality, and creativity.It is swarm intelligence".On the other hand, Lévy [56] defines 'collective intelligence' as "shared intelligence everywhere, constantly valued, coordinated in real time, that drives an effective mobilisation of competences".This coordination requires a sort of appropriate communication, with the communication and information technologies being those that better harmonise the interactions.In this way, "cyberspace appears as the organisational tool for all kinds of communities, and all dimensions in existing collectives, but also an instrument which permits that allows intelligent collectives to link up between them" [57].

The Right to the City and Urban Complexity
The concept of 'the right to the city' was defined by Henri Lefebvre [58] as the right of city inhabitants to build, decide, and create the city.The author proposes a city model based on citizen participation and the right of everyone to enjoy the city.He opposes the concept of the city as a space of consumption, transit, and work in order to defend the city as a space of life.Under this approach, it is a social space produced by human action that claims the 'right to the city' as a fundamental right that must be recognised by the state.On the other hand, Harvey [2,4] adds that it offers an alternative to traditional forms of 'urban governance', which generally exclude citizens and perpetuate social inequalities.Additionally, he asserts that the city is not only a physical structure, but a product of the social relationships and the political struggles that happen within.It is a political instrument to mobilise citizens in the search for more equal and fairer cities [5].
In a context where cities are 'complex', their main character is the diversity of their population, activities, and structures.Such diversity supposes many challenges, as well as an opportunity for design, allowing us to tackle these challenges in a creative and innovative way [30].Here, design could play a fundamental role in the creation of more habitable, more sustainable, and more fair cities.This potential must be able to adapt to the complexity of cities and to the constant uncertainty that are its main characters.If we tend to models that identify cities with complex systems, it could be convenient to abandon traditional urban planning to emphasise citizen participation and collaboration [35].The growing complexity of today's cities could also be defined as the set of interconnections, interdependences, and heterogeneities that are the main character of urban spaces.This is a phenomenon that has grown exponentially in recent decades, and it is necessary to understand why to face its key dimensions-diversity interconnection and inertia [29].Three concepts are key in the science of complexity and are very relevant to collaborative design: (1) emergency-it cannot be foreseen from its individual elements; (2) adaptation-ability to adapt to the new conditions on the environment; (3) self-organisation-to be able to spontaneously organise without needing any external agent [33].In fact, 'self-organisation' is fundamental to building positive conditions for interacting and cooperating between urban actors.In an urban scenario, it could emerge through informal networks, local initiatives, and innovative practices.It is a proper approach to handling the complexity and the uncertainty related to the contemporaneous cities.It can be concluded that these concepts aim to generate more resilient and sustainable urban processes that, simultaneously, could improve the quality of life of citizens [37,38].

Collective Creativity in Urban Spaces: Participation, Collaboration, and Co-Creation
If the architecture repurposes its connection with the society and develops an interest for the common, it will surely generate more human cities.In cities, there is a facade of disorder and chaos, but it is actually the concealment of a complex order.To better understand urban order, one must understand cities and neighbourhoods as living organisms that are able to generate and maintain safety on their streets and to ensure freedom within the cities.Cities build their order 'bottom-up', and, as emerging systems, cities have the ability to learn and recognise patterns."Metropolitan space is usually portrayed as ascending lines over the horizon, but the true magic of life in cities comes from its bottom" [59].To enable these synergies, it is important to have real urban integration.In this sense, neighbourhoods are the more efficient local units of self-government.Furthermore, every action-as little and humble as it seems-is essential, because as Jacobs states, "despite so many experiments, planned or unplanned, there is no substitute for lively streets" [60].
Our starting point is that the city is a valuable resource that should be managed and preserved in a collective way.Therefore, democratic governance is forced to promote the participation of citizens in the decision making about the future of their neighbourhoods [61].This trend of citizen integrations in the creation of public spaces has three fundamental elements: citizen participation, co-creation, and social transformation [62].It handles the implying of citizenhood, building spaces for the dialogue and the collaboration, but also participation in the design and the construction of these spaces.It is certainly remarkable that participation has four key dimensions: political, social, cognitive, and spatial.And four types of participation can exist as follows: formal participation, linked to the authorities; informal participation, out of the established frameworks; direct participation, in which citizens make decisions and are accounted for those decisions; and indirect participation, in which there are citizen representatives [32].Moreover, it could be defined as participative creativity in the collective process, located and distributed in what is produced in the context of interactions and social relationships.Therefore, spaces of creative participation represent a promising way of promoting collaboration, innovation, and empowerment of the citizens through connection, experimentation, and recognition [63].
Today, there is abundant research on 'co-creation' as a tool for designers who are interested in creating innovative solutions.Furthermore, it is argued that co-creation can build stronger relationships between designers and users [64].Among the elements that are linked to the dynamics of urban co-creation, it is notable that the active citizen participation, the facilitation of agents for the creation of collaborative environments, and the organisation must have a clear structure and a well-defined process [23].Furthermore, the promotion of urban resilience requires the development of effective tools for participation, which are based on co-design approaches linked to the network and open code [41].Specifically, the so-called 'creative places' have grown in relevance today.Spaces such as cultural and art centres, but also co-working and digital manufacturing spaces, play an important role in promoting collaboration, innovation, and social development within cities [65].There are three key dimensions that describe these spaces: social cohesion and citizen participation; innovation and economic development; and sustainability, both social and environmental.Their potential lies in their capacity to generate synergies between various social agents, institutions, and economic sectors.In this line, it is held that collective culture in public spaces should not be limited to traditional spaces.It handles hybrid spaces, where commercial, cultural, and social activities are blended, and are especially suitable for the development of new forms of collective culture [48].In all these spaces, even those ruled by collaborative processes, conflicts and disagreements also emerge.Therefore, it is necessary to develop tools that help in their management to obtain satisfactory results for all the parties involved [10].

'Urban Laboratories' and Temporary Use of the City
Currently, both architectural collectives and emerging citizen processes focused on collaboration are multiplying and have generated several 'Urban Laboratories' whose experimentation is placed in the avant-garde of 'new economic, cultural, social, and political configurations within cities' [14].Crisis has served as a great impulse in recent years, as it has generated realities that have stimulated the solidarity and action of neighbours that share a common place.Projects take advantage of situations of non-occupation and obsolescence to relaunch the urban fabric and the social cohesion, recovering the public space for the citizens.The growing interest in participative practices of public space creation is a sign that citizens are willing to take control of public spaces in the era of urban austerity.While working with citizens, establishing bonds, empowering them, and evaluating public spaces, urban planners could create more inclusive, resilient, and fair spaces [66].Creative initiatives that combine both participative approaches 'bottom-up', and formal strategies 'top-down', can create unique public spaces and not only commercial ones.
Architecture collectives have applied their new processes of production-without rigid hierarchies-to the urban projects in which they are working.Related to recent urban scenarios, Adolfo Estalella states [67]: "cities are mutating from one side of the globe to the other.Inhabitants that used to transit through its streets or walk through its gardens now live in the cities to furbish their places and occupy their lots.A new form of citizen urbanism emerges through which urban space is redesigned on and by the street".The collective 'Paisaje Transversal' adds that "reformulation of the axioms that ruled the last century goes through subverting the object and process logic, claiming instead the value and potential of the process the image, the icon.It is also essential to recover the social value of architectural practice.In other words, let us be able to provide our knowledge and tools for the civil society to facilitate social transformations" [68].
'Urban laboratories', also known as urban social laboratories or urban living laboratories, are a way of open innovation, of experiencing, and of co-creation that use citizen participation to address urban challenges [18,21,[69][70][71][72].The European Union officially recognised this concept in 2006, when the European Network Living Labs (ENOLL) was founded [73].However, its beginnings date from the early 1990s, when a research team from the University of Pennsylvania developed a problem-solving method for a neighbourhood in Philadelphia [74].The potential of these laboratories consists of their ability to generate new forms of social interaction, economic production, and political participation in urban space.In addition, it offers methodologies that address complex and emerging urban challenges [20,69,75].Therefore, this participatory approach not only improves the quality of urban design, but also promotes social cohesion, civic participation, and people's empowerment [76].On the other hand, urban innovation practices are not only reactive responses to crisis situations-as proved on many occasions-but represent a commitment to social transformation and building more equitable and sustainable cities where people's well-being increases [19,22,50,77].
'Urban Laboratories', which flourish in many cities, have a common 'adhocracy' and recovery of spaces for participation and citizen management.This concept contrasts with bureaucracy, and is defined in organisations management framework as the absence of hierarchies.Robert H. Waterman describes this term as "any form of organisation that beaks bureaucratic lines in order to reach opportunities, solve problems, and obtain results" [78]."Alternative processes to conquer urban wounds that stimulate new empowerment of the city and resistance to commodification of the public" [79] are being implemented.Selfmanaged urban spaces, as well as collectives of architects and designers, have thrived in recent years, empowered by gathering movements and social claims of the citizenhood."It makes clear that there is another way to participate in the composition of the city by building spaces and designing needed so it is possible to live in common" [67].It handles "urban self-managed spaces of all kind: public spaces, social spaces, cultural spaces, central or peripheral spaces, citizens, neighbours spaces or whatever you would like to call it, they are occupied, squatted, transferred, rented. . .Spaces that have returned to the city and to the street its essential function of scenario, outline and environment of life in common" [80].The challenge now is to make these claims, initiatives, and principles effective through public policies, promoting a new combination of disciplines to integrate the social, economic, and environmental development of urban contours [81].
This urban transformation movement has a holistic scope that goes beyond a simple physical transformation of the urban space to also cover social relationships and the fabric of the community [82].Some of its contributions are the improvement of the quality of life of citizens, the strengthening of the link between local authorities and neighbours, the improvement of the development and quality, the acceleration of decision making and smooth implementation of solution implementation, stimulation of learning, and the continuous improvement and boost of the flexibility and adaptability of spaces, inter alia [19,70,72,76].The so-known 'DIY Urbanism' (Do It Yourself) [82,83] also promotes the solidarity, cooperation, and collective action of citizens, contributing to fairer, more democratic, and more sustainable societies.It is remarkable that some research which has focused on digital 'Urban Laboratories' especially favours issues such as accessibility, efficiency, innovation, open democracy, and collaboration [84].However, it also takes into account challenges, such as the lack of financial resources, resistance of institutions, and lack of legal background [50,83]; the constraint to define goals clearly, in a clear way, and the conflict management and scalability of conflicts [19]; social inequities, environmental degradation, and lack of available spaces [85]; pressures from authorities and agents of the real states [82]; integration into physical reality, validation of ideas, or consent of local governments [84].
The 'Occupancy' of public spaces has as a primary goal the claim of 'the right to the city', and it handles an emerging trend that is transforming the urban landscape [86].Furthermore, this practice is understood as a way of urban activism and as a strategy for the temporal reuse of public space [27,87].Several case studies of 'Temporary Urbanism' examine this kind of intervention that promotes citizen participation, as well as the creation of dynamic and comfortable spaces [24][25][26]88].In all this research, it is concluded that it handles the temporary transformation of abandoned or underused urban spaces into meeting places, cultural events, and leisure activities.This temporary utilisation offers opportunities for the regeneration of public spaces, as well as experimentation with new models of urban development.Linked also to the concept of 'Urban Laboratory', these spaces are characterised by promoting innovation, flexibility, and collaboration in their quest to create more liveable and sustainable environments [89].When a quality and well-managed 'Temporary use' is achieved, especially those related to ecological activities, it can make a significant contribution to the sustainable development of a neighbourhood.Similarly, 'Temporary use' could reduce the negative impact of vacant urban spaces [26,90].In essence, our cities have always been the subject of transformations and redesigns, but the contribution of temporary uses can be a shunt for these processes-dealing with the important role of technology and current social networks [91].

Methodology
For the development of this research, the complexity of a unique case was studied as a reference of 'Urban Laboratory' (Figure 1).The 'El Campo de Cebada' project has been examined as a paradigmatic case study of this type of collective urban production process, in which multiple collectives of architects and designers have participated.This study analyses a series of variables that show the capacity of collective creativity processes to address urban complexity and to articulate actions for the regeneration of degraded urban lots.In this research process, a literature review was carried out to describe the circumstances surrounding the 'El Campo de Cebada' project and the entire development process.Furthermore, the phenomena of collective creativity in this case, as well as the elements that define its level of complexity, have been studied in an exhaustive and qualitative way.

Study Case Selection
'El Campo de Cebada' has been chosen as a case study (Figure 2), located in the neighbourhood of Madrid, not because it is a common space, but an "urban experience based on community, inclusion, and connection, and not just the cold and individualistic logic of capitalistic speculation" [92].Despite its very innovative and risky approaches, it has proved long-term stability and great success within the community [16], with a guild of collectives with a large trajectory of social success, from its beginning in 2010 until its closing in 2017."El Campo de Cebada is a critical position that is woven together to build positive actions.It is a public space that does not look for profit or for advantages for the associations and people who are in charge, but to learn a way of considering the city in a very different way, in which the public returns to be common, belonging to all the people" [93].

Criteria for Case Selection
'El Campo de Cebada' has been selected because of its long trajectory over time and repercussions.The project began in 2010 and closed in 2017, but it could be said that it was completed when the new sports centre was built in 2022-the competition, design, and construction of which were the reasons for the creation of the citizens' initiative.It is also a large space, covering 1.2 hectares, which made it possible to generate a multifaceted urban project.It is a space with great evolution, resistance, and transformation over time, demonstrating its capacity for adaptation and resilience.'El Campo de Cebada' is located in a strategic place, with great accessibility and open spaces that facilitate the development of multiple collective activities.In an initial analysis, this space manifested itself as a complex urban project and, therefore, seemed suitable for this type of study.Finally, the high level of intrinsic motivation of citizens to create and maintain the project was taken into consideration, mainly due to the feeling of loss of a community space in the neighbourhood-the sports centre of 'La Latina'.

Analysis of the Case Study
The case study was carried out through direct observation using a variety of resources, as listed below.First, an exhaustive review of the literature and publications in nonacademic media was carried out.In addition to the review of the available scientific literature, social networks and digital publications of citizen initiatives-active even after the closure of the laboratory as a physical space-were monitored.We also analysed graphic documentation, identifying, for example, the activities carried out and dates, the actors involved in them, the management mechanisms and the infrastructures used-produced by citizens and professional groups.In addition, press publications have been reviewed to record both the important chronologies-on the evolution of the urban space-and characteristics of the events that took place.Finally, interviews were conducted with the collectives of architects involved in the project, and available audiovisual materials were viewed to confirm the variables identified.Once the necessary data had been collected, they were analysed and interpreted.In general, the information obtained was classified to define the study variables involved in the description of the evolution of the level of complexity of this urban space throughout its history.

Study Variables
Once the possible variables were identified during the case study analysis, they were refined and classified.An attempt was made to establish variables that were easily distinguishable and characteristic of the diversity and richness of the case study.It was also important to establish factors that could be extrapolated to other urban spaces.The variables identified were classified as follows: (1) times-chronology of the events and elements that emerge in 'El Campo de Cebada'; (2) agents-actors that are part of the project; (3) management-forms of administration and governance; (4) social dynamicsstructures and organisation; (5) Enabling infrastructures-material elements built and used; and (6) actions-activities developed.

Complexity Map
The application of the variables at different times, which show the evolution of this urban space, was carried out graphically by means of a so-called 'Complexity Map'.This map is a data graph that aims to order and visualise the complexity of 'El Campo de Cebada'.Mental or conceptual maps [94] are graphic representations of interrelated ideas, concepts, flows, or processes.In this study, the map is original and has no similar antecedents, as it was elaborated especially to visualise the complexity of 'El Campo de Cebada'.In this graph, all the study variables have been articulated chronologically, visually showing the complexity of this urban space during its historical evolution to the present day.This map shows the variables represented by different geometric shapes and colours to identify the changes in complexity that occur in this urban space.Specifically, it is possible to appreciate the proliferation of items that arose which are linked to the variable diversity of types of agents, modes of management, social dynamics, enabling infrastructures, and actions or activities.This map was the analytical approach used to draw conclusions.

Results and Discussion
4.1.Description of the Study Case: 'El Campo de Cebada' as a Complex 'Urban Laboratory' 'El Campo de Cebada', located in the 'La Latina' neighbourhood, it is the history of an urban void [94] or the result of the demolition of a shared space.During the XVI century, the 'Plaza de la Cebada', one of the oldest squares in Madrid and a space full of life and history, was turned into a concrete hole in 2009.This square was built over an old Muslim cemetery that was outside the walls of the town.There, the barley for the kings horses was separated from that intended for the cavalry regiment, and it was the place where peasants coming from the surroundings of Madrid came to sell the grain.It was used as a market for cereals, vegetables, and pork products, with an outdoor stand, which resulted in the "unifying element that generated the activity was the void itself, which opened in the city to host whatever activity required" [95].
Due to the growth of the population during the last decades of the XVIII century, the construction of the 'Mercado de la Cebada' was projected [96].It was inaugurated in 1875 by the king Alfonso XII and, during the beginnings of the XX century, became one of the biggest and most important markets in Madrid.The modernist building was replaced by a new one, "but the location of the market neglected the public space, forgetting what it owed, and the square was resigned to a background spaces that lost connection with other little squares of the area, in addition to the growth of rolling traffic made that pedestrians to be kept limited to a functional perimeter, and the main door was left of the public space" [95].In 1968, the downturn of the public market-due to the appearance of other ways of commerce-and the growing worry in the city for hygiene provoked that half of the building was transformed into a sports centre that occupied the last empty space of the square.The building was constructed with a covered swimming pool and turned out to be the only place for relationships in that quarter.
By the in XXI century, only half of the market stands were occupied, and the local administration approved the 'Special Improvement Plan' [97] in order to rearrange the area.One of the goals of the plan of action for the revitalisation of the urban centre of 2004 was the realisation of a complex equipment.The so-called 'Plan E' was the starting point of an idea competition for the refurbishment convoked in 2006-the first prize turned out null-and in a later call during 2007, which was won by the proposal entitled '+Público'.The preliminary design was submitted on 7 December 2007, and the final project was delivered on June 2008.This proposition raised a much more modern and functional market, a sports centre, an underground car park, and the creation of new green areas that built meeting points and that favour urban habitability.Although the problem related to the money scarcity was well-known, the demolition of the existing sports centre began in 2009.In 2010, it was publicly admitted that there was no budget assigned to carry out the project, and it all turned out in a concreted and fenced void of 2500 square metres attached to a decadent market (Figure 3): "La Cebada was nothing, it was a hole in the centre of Madrid" [98].Lozano-Bright defines the situation of urban spaces "For a time and due to the heat of a neoliberal climax, city is no longer a place for reunion, discussion wandering, commercial exchange, in order to be fragmented into a parcel conceived just for the mere transit and consumption" [99].

There were a series of circumstances, behaviours, and actions that created a stable 'Urban Laboratory' over time.It probably took a history of social movements of assembly nature for the 'El Campo de Cebada' to become a reality (Figure 4).As an example, the citizen movements in Madrid of '15M', also known as the 'Indignados', stand out.The '15M' was formed from the demonstration of 15 May 2011, where camps and assemblies emerged, which later became formalised as collectives and even political parties.Through an emerging citizenship, from their indignation [87,103], a whole series of dynamics based on social innovation and the city open to the citizen were activated: "This is how El Campo de Cebada began to grow, people from the neighbourhood of all ages, together with young architects, came together to imagine how the space could be used temporarily, until the sports centre project was restarted" [104].The following words of Torres clarify the focus of this space: "El Campo de Cebada is a critical position that attempts to construct propositional actions.It is a space with a public character that does not seek any profit or advantage from the associations and people who coordinate it, but to learn a way of seeing In 2010, the 'Basurama' architectural collective was commissioned to take charge of the 'Noche Blanca' in Madrid, and under the title '¡Hagan Juego!', all of the population was invited to participate in an active way.The proposal was based on working with what was existing-physically and symbolically; networking-locally and globally; a proactive city; cutting production expenses = increasing number of projects; residues = resources, and second uses = continuous development projects.In this context, they discovered La Cebada as an opportunity space for the city and invited the French and English architects collective EXYZT to make an ephemeral intervention that was called 'City Island' [100,101].This collective of Parisian architects usually worked in empty spaces or buildings in the cities, buying them temporarily with the allowance of their owners and transforming them through simple structures and mobile units with a 'Do It Yourself' aesthetic that is quite cheap and easy to build.The ephemeral project included a swimming pool, a bar, and a concert space; so, over 10 days, the La Latina quarter could again enjoy a common space.From then on, this light focused on what was just a lifeless hole and served to reflect and discover its true value: "From then the concrete esplanade has been a fertile place" [102].

'El Campo de Cebada' could be defined as a collective of collectives and as a living process, where the concept of emerging citizenship stands out as a social innovation for the recovery of an abandoned space.The takeover of the city by the residents of a neighbourhood generates highly creative processes, stimulated by the feeling of loss of the only relational place they used to enjoy.From this emerges a social, political, and ecological space, where experimentation and problem solving are constant and where multiple scales and formats are developed for the revitalisation of the neighbourhood through flexibility and dynamism [90,94].A meeting place, but also a laboratory where new formulas for common debate, social cohesion, and enjoyment are tested.In this way, a multilayered city is generated-through the material-digital duality-weaving local community through the stimulation of relational activity and the creation of networks, and, at the same time, thinking about the global repercussions of the project in an open and connected way with the rest of the city.In complexity environments, architecture explores new models of production that are capable of giving answers to the rising challenges.At this point, Edgar Morin stated, as a referent of complexity as a concept: "It is complex whatever could not be summarised in a master word, whatever that could not be explained by a law, whatever that could not be reduced to a simple idea" [105].On the other hand, instability, uncertainty, and disorder look like a good breeding ground for generating changes in existing structures and facing new situations.In this context, collaboration processes-thanks to their ability to work with higher levels of complexity-are introduced in a natural way.But we need to consider global visions that integrate all the elements to help us understand the movements that surround us and that build new ways of acting over our environments.

Research Variables: Measuring Elements of the Complexity of 'El Campo de Cebada' 4.2.1. Timeline
This variable is very relevant, as 'El Campo de Cebada' is characterised by a biography of growth, continuous progress, and reinvention.Here, the figure of the promoter is diluted, and all the agents involved are part of the process and interrelate from the beginning.Among the events and actions that have took place, we can see how, from the proposal of the project to the City Council in 2010, a radical change has taken place in terms of the management and production of the 'El Campo de Cebada' space.It is a new paradigm of common space that integrates a greater diversity in the agents involved, as well as in the management of the space itself, the social dynamics, the design of enabling infrastructures, and the actions developed.There is another key concept for understanding the temporalisation of the project: expiration.'El Campo de Cebada' is characterised by the 'Temporary Use' of the space, defined by the annual renewal of the concession for temporary and free use of the property and by the date of closure due to the start of the works of the new municipal sports centre.Thus, uncertainty constitutes the backbone of the project, which encourages creativity in the search for adaptation to a transitory situation.The project is so solid that, as was finally proved, it would seek the continuity of the space in another place when the physical space was not available.Finally, 'El Campo de Cebada' handed over the keys to the City Council in 2017 to start the works of the New Sports Centre; however, it continues its activity through social networks and using other common spaces.Promises of the inclusion of a roof for citizen management in the new building disappeared, and other neighbourhood spaces in Madrid have also been evicted.Nevertheless, these are spaces of great immaterial wealth that seek new opportunities, as the place of occupation is not as relevant as the people's project and the discovery of their right to the city.As a gesture of collective care for this place, the neighbours collected each of the plants as a 'party' so that on each balcony of the citizens of La Latina, a part of 'El Campo de Cebada' survives.The works of the so-called 'Centro Deportivo Municipal La Cebada' were finished in January 2022, and at the end of the same year it was inaugurated.The complexity map shown below visualises the temporalisation of not only of the process of 'El Campo de Cebada' but also of the previous uses of that part of the city.In short, it is confirmed that this urban space is a living space in time in which-once the citizen-initiated management has begun-the level of complexity is accelerated through the intervention of the other variables.
These data, together with those explained in the description of the case study, have been categorised and ordered for implementation in the complexity map.From the 11th century Muslim cemetery, and the other antecedents of the case study, to the completion of the 'El Campo de Cebada' project, the transformations have been ordered to analyse the temporal evolution of the complexity of this urban space.

Agents
Agents are essential for this project, as one of the fundamental pillars of the project's success is the wide variety and the vast number of components that are part of 'El Campo de Cebada'."Promoter does not exist from the technical perspective and is actually about the purchase of an unuse place by a neighbours community" [79].From its beginnings, it has been an open and inclusive initiative, in which the participation of as many elements as possible, symmetry, and hybridisation between them have always been always welcome (Figure 5).Subjects that have taken active part are, first, citizenhood, escorted by neighbours associations and federations, besides architect and designer collectives, artist platforms, cultural agents, commerce associations, universities, and research groups as well as the public administration.In terms of professional collectives that have collaborated in different stages and with different intensity, we can include the following: 'Basurama', 'EXYZT', 'Zuloark', 'Todo por la Praxis', 'PKMN', 'Taller de Casquera', and 'Paisaje Transversal'.They emphasise the new and diverse role of the architect, in service of the needs of the whole process, in a continuous way and without any predefined expiration date.Intervention comes as a form of accompaniment and mediation, designing services, managing, developing strategies, negotiating, coordinating, teaching, and even building devices.

Management
This variable is crucial in defining the nature of the organisation of 'El Campo de Cebada'.Here, it is called more precisely 'co-management' as all the agents collaborate to manage the space, generating shared responsibility.Firstly, management starts with a request for transferring the space-made by the neighbours, architects of different collectives, and the neighbours association.Then, a project was redacted and submitted to the department of governance, treasury, and public administration of the city Council.The management of 'El Campo de Cebada' is the management of complexity.It handles a chaotic environment that is always swinging between order and chaos, where system selforganisation emerges in a natural way.In this sense, there existed just a few rules as a sort of internal regulation.These rules solely pretended to give a minimum level of order through the following bases: activities would only be approved in a general assembly; noise level would not disturb neighbours [106]; access would always be free of any charge; there would exist an opening schedule; cleanliness would be maintained after enjoying the space; no violence and no discrimination would be allowed within the premises.On the other hand, the funding issue was also based in freedom, in a way that the economic sustainability would never depend on institutions, administrations, or private companies.It handles a self-funding that begins with an initial grant and without profit-making intention, feeds from 'crowdfunding' or 'microsponsorship', and forms the won prizes from the money that could have been collected during any event."Management does not depend on one or another, it depends on every single one… It is not a collective; it is not an association that makes decisions… but a common space that gives the possibility of participating in it to whom it may intervene" [98].

Social Dynamics
Firstly, the project is characterised by 'adhocracy', horizontality, and self-organisation.Beyond citizen participation, one could speak of an urban parliament where a large constellation of agents collaborates to generate collective intelligence.Like ants or bees, it is a highly advanced social engineering that creates enormous synergies through common sense and freedom.It is the construction of a real and open community-but also one digital and networked-characterised by communal and assembly-based decision making.And, as in any bottom-up process, order was created from the bottom up.In terms of conflict management, instead of fighting against it, it is decided to inhabit it, to confront it by encouraging commitment and dialogue, creating, little by little, a sense of belonging to the place that generates responsibility in the users of the space."The city, the conscious collective, associates in community swarms to recover the commons.Not only physical spaces, but also the emotional,

Enabling Infrastructures
This is dedicated to the material elements that have been built through direct processes and pedagogical environments.They are not designed as an end in themselves, but as mechanisms favouring the creation of events, situations, and relationships.In this way, an equipped square with infrastructures was configured, open and at the service of the citizens to facilitate its free use and enjoyment (Figure 6).The construction and manufacturing process was community-based and participatory, with a pedagogical workshop format open to all agents who wished to collaborate.As an example, the 'Hand Made Urbanismo' workshops were based on open source, recycling of materials, and collective learning.All the ideas developed had to be adaptable, accessible, and replicable so that other spaces can use them at any time.Indistinctly, projects have been generated for the design and manufacture of furniture, mobile stands, installation of devices-cultivation tables, mobile planters-for urban gardens and vegetation, viewpoints, urban art installations, sports courts, 'the device', the shade elements, and the geodesic dome.All these elements have collaborated in the construction of the common space and have been created from processes of collective creativity.These workshops have been accompanied and promoted by different groups of architects, designers, and artists, such as 'Paisaje Transversal', 'PKMN', 'Zuloark', 'Basurama', 'Taller de Casquería', 'Todo por la Praxis', and 'Prototyping'.Three workshops were held, called HMU1 (auditorium of the 40 different chairs), HMU2 (furniture Commons) and HMU 3 (Rehab of public space).They were organised with the PEI of the Pontificia Universidad Javeriana de Bogotá and the Zuloark collective and counted with the collaboration of students and interested citizens.

Actions
The last variable is a consequence of the activation of all previous structures.It is the life of 'El Campo de Cebada', which defines it, which makes visible its success as a public space, and which builds its social capital.The activities (Figure 7) that move the energy of this space are always open and free and can be classified into the following types: governance-meetings, coordination assemblies, councils, and management coordination with the administration; maintenance-repair of furniture, care of the garden and cleaning; Everyday-meeting, playing, resting, reading; sports-football, basketball, aerobics, training; cultural-cinema, theatre, literature, music, gastronomy, circus, dance; pedagogical-popular university, self-training summer school, construction workshops; and citizen Infrastructure-use of the space for groups and collectives with social development objectives.The events programme is spread through the panels at the entrance gate, the website, social networks and, of course, through word of mouth among neighbours in the neighbourhood.Programmes are always alive and active, creating periodic cycles over time when they are well received, renewing themselves, and coming up with new events all the time."The out turn of pure necessity.'El Campo de Cebada' is proof that crises also create opportunities.On the site of a demolished swimming pool, the surrounding neighbours built a place for human exchange, for creativity, for community gathering both live in the heart of Madrid and online.Everyone is invited to participate.The motto of 'El Campo de Cebada' is transparency.People decide what happens in this place" [107].

It could be said that where a thousand years ago a cemetery slept, a space full of life awoke.A place called 'El Campo de Cebada', where swarms of citizens pollinate the nodes of extensive networks that make contemporary complexity flourish.Generating a new paradigm of common spaces that claim the right to the city [108] through collective strategies of immaterial architectures.As the 'Basurama' collective-already involved since the 'City Island' project, the predecessor of 'El Campo de Cebada'-affirms: "public space processes have left to have form in order to have meaning" [109].
The ultimate purpose of the 'El Campo de Cebada' case study is to produce inductive reasoning so that from research, observation, and data collection of a particular case, conclusions applicable to other cases can be drawn.As a result, this model of variable analysis can be extrapolated to other 'Urban Laboratories' cases.It can also be used as a tool for the design of resilient and sustainable urban spaces in the future of cities.

Conclusions
From the study carried out, it can be confirmed that the collaborative production processes of 'El Campo de Cebada' assume a high level of complexity.It has also demonstrated its suitability as a reference for 'urban laboratories' and for experimenting with models of citizen-initiated spaces.It is a project that promotes collective creativity, citizen participation, and the search for alternative resources.And it opens a way to take on the contemporary complexity of cities through collaborative processes.In this type of common spaces, it is possible to recover collective social well-being.Here, beyond territories dedicated to consumption, open and flexible places are designed to encourage diverse activities and social cohesion.In times of crisis, it is interesting to promote these urban models.In fact, the recurrence of crises of various kinds is becoming more and more frequent.So, it would be pertinent to compensate for individual and collective difficulties with complex community spaces.Projects that can provide, with few resources, actions that improve the resilience of neighbourhoods and cities.
The proposed complexity analysis model could be applied to other spaces, as well as the use of variables for the design of new 'Urban Laboratories'.In future research work, the model is intended to be applied to other case studies to test their feasibility.In 'El Campo de Cebada', the evolution of the level of complexity is easily seen due to its antagonistic antecedents.However, it is possible that, in other cities, other neighbourhoods, and other urban spaces, an adjustment of the proposed model may be necessary.Furthermore, and although it has not been the aim of this paper, it would be interesting to extend the study in the future to include political and anthropological aspects in the context of a wider transdisciplinary project.
