2.1. Challenging Environments: Individualisation and Collaboration in Complex Scenarios
During the Industrial Revolution, progress was made through accumulation, ignoring the environmental impact and any other collateral damages. During the postmodern period, progress does not consist only of ‘improving’, but it implies losses, setbacks, and the appearance of problems that are difficult to solve. In fact, the nondesirable effects of the progress start to be taken into consideration. Walter Benjamin [
47] inspired by the ‘Angelus Novus’ of Paul Klee adds that progress is made looking backward and not only moving forward without reflection and without considering the consequences of our actions. On the other hand, ‘Capitalism’ -apart from using a limited time frame and not considering the long-term consequences of their actions- is based on the individualism of societies, promoting competence and specialisation, and disconnecting people as a collective. Until very recent times, the specialisation has been crucial to manage the huge dimension of human knowledge; however, a more holistic view has emerged as a response to the uncertainty of the contemporaneous world. During the XX century, and usually linked to crisis periods, diverse collaborative experiences within architecture and within art. Some of the collectives that emerged during the twentieth century—surely a source of inspiration for contemporaneous collectives—that emerged during the twentieth century are CIAM, TAC ‘The Architects Collaborative’, ODAM ‘Organização dos Arquitectos Modernos, ‘grupo CoBrA’, ‘Team 10′, PAGON, ‘Grupo R’, ‘Internationale Situationniste’, ‘Metabolism’, ‘Archigram’, ‘Architecture Principe’, ‘Grupo 2C’, inter alia. Nevertheless, it is presently when much more complex collaborative processes are implemented.
‘Individualism’ is understood as an independent attitude from others. Although the concept of ‘individualisation’ also appears as the process of becoming an individual. Regarding this definition, Ulrich Beck claims the return of individuals to society and argues that individualisation makes integration possible: “As paradoxical as it seems, it is individualisation and fragmentation of growing inequities in separated biographies that make up a collective experience” [
48]. However, what has prevailed throughout history is ‘cooperation’. According to Kropotkin [
49] “the rampant individualism is a proof of more modern times, but it is certainly not a character of the ancient human”. And he continues to argue that, as much as the fight and the competence stand, it has always prevailed on the mutual support and the common good. So collaboration was the natural way to survive and move forward for ages. However, self-affirmation of the individual is also important for progress and for balancing the more than possible homogenising effect of the community. But “isolation could act against cooperation” [
50], so it could be interesting to strengthen and increase networks to optimise interactions and synergies.
‘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 [
51] 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 [
52] 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, 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” [
53].
2.2. The Right to the City and Urban Complexity
The concept of ‘the right to the city’ was defined by Henri Lefebvre [
54] 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 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 fairer cities. This potential must be able to adapt to the complexity of cities and to the constant uncertainty that is its main character. 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 cities could also be defined as the set of interconnections, interdependences, and heterogeneities that are the main character of urban spaces. It is a phenomenon that has grown exponentially in recent decades, and it is necessary to understand y to face its key dimensions—diversity interconnection and inertia [
29]. Three concepts are key in the science of complexity and very relevant to collaborative design: 1) emergency–it cannot be foreseen from its individual elements-; 2) adaptation-ability to get adapted to the new conditions on the environment-; 3) self-organisation–to be able to spontaneously getting organised not 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 handle 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 citizens [
37,
38].
2.3. Collective Creativity in Urban Spaces: Participation, Collaboration and Co-Creation
If the architecture repurposes its connection with the society and develops the 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” [
55]. 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” [
56].
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 participation of citizens in the decision making about the future of their neighbourhoods [
57]. This trend of citizen integrations in the creation of public spaces has three fundamental elements: citizen participation, co-creation, and social transformation [
58]. It handles the implying of citizenhood, building spaces for the dialogue and the collaboration, but also participating 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 be i: 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 as the collective process, located and distributed that 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 [
59].
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 [
60]. Among the elements that are linked to the dynamics of urban co-creation it is notable the active citizen participation, the facilitation of agents for the creation of collaborative environments, and the organisation that 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 [
61]. There are three key dimensions that describe these spaces: social cohesion and citizen participation, innovation and economic development, and sustainability, both social and environmental. Its potential lies in its capacity to generate synergies between various social agents, institutions, and economic sectors. In this line, it is held that collective culture in public space 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 [
62]. In all these spaces, even ruled by collaborative processes, conflicts and disagreements also emerge. Therefore, it is necessary to develop tools that help in its management to obtain satisfactory results for all parties involved [
10].
2.4. ‘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 of great impulse in recent years, as it has generated realities that have stimulated the solidarity and the action of the neighbours that share a common place. Projects that take advantage of situations of nonoccupation and obsolescence to relaunch the urban fabric and the social cohesion, recovering the public space for the citizen. The growing interest in participative practices of public space creation is a sign that citizens are willing to take control of public space 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 [
63]. Creative initiatives that combine both participative approaches ‘bottom-up’, as 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 [
64]: “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” [
65].
‘Urban laboratories’, also known as urban social laboratories or urban living laboratories, are a way of open innovation, of experiencing and co-creation that uses citizen participation to address urban challenges [
18,
21,
66,
67,
68,
69]. The European Union officially recognised this concept in 2006, when the European Network Living Labs (ENOLL) was founded [
70]. 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 [
71]. 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,
66,
72]. Therefore, this participatory approach not only improves the quality of urban design, but also promotes social cohesion, civic participation, and people’s empowerment [
73]. 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,
74,
75].
‘Urban Laboratories’, which flourish in many cities, have a common ‘adhocracy’ and the recovery of spaces for participation and citizen management. This concept contrasts with the 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” [
76]. “Alternative processes to conquer urban wounds that stimulate new empowerment of the city and resistance to commodification of the public” [
77] are being implemented. Self-managed 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” [
64] . It handles of “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” [
78]. 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 [
79].
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 [
80]. 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,
67,
69,
73]. The so-known ‘DIY Urbanism’ (Do It Yourself) [
80,
81] also promotes solidarity, cooperation, and collective action of citizens, contributing to fairer, more democratic, and more sustainable societies. It is remarkable that some research focused on digital ‘Urban Laboratories’ favours especially issues such as accessibility, efficiency, innovation, open democracy, and collaboration [
82]. However, it also takes into account challenges such as the lack of financial resources, resistance of institutions and lack of legal background [
74,
81]; the constraint to define goals clearly, the goals in a clear way, the conflict management and scalability of conflicts [
19]; social inequities, environmental degradation, and lack of available spaces [
83] pressures from authorities and agents of the real states [
80]; integration into physical reality, validation of ideas, or consent of local governments [
82].
‘Occupancy’ of public spaces has as primary goal the claim of ‘the right to the city’ and it handles an emerging trend that is transforming the urban landscape [
84]. Furthermore, this practice is understood as a way of urban activism and as a strategy for the temporal reuse of public space [
27,
85]. 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,
86]. In all this research, it is concluded that it handles temporary transformation of abandoned or underused urban spaces into meeting places, cultural events, and leisure activities. This temporary utilisation offers as opportunities 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 [
87]. When a quality and well-managed ‘Temporary use’ is achieved, especially those related to ecological activities, it could make a significant contribution to the sustainable development of the neighbourhood. Similarly, ‘Temporary use’ could reduce the negative impact of vacant urban spaces [
26,
88]. 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 an important role of technology and current social networks [
89].
