P2P (PEER-TO-PEER) URBANISM is an innovative way of conceiving, constructing, and repairing the city that rests upon five basic principles.

1) P2P Urbanism defends the fundamental human right to choose the built environment in which to live, selecting from amongst diverse features those that best meet our needs.

2) All citizens must have access to information concerning their environment so that they can engage in the decision-making process. This can be actively supported by ICT (Information and Communication Technology).

3) The users themselves should participate on all levels in co-designing and in some cases building their city. They should be stakeholders in any changes that are being contemplated in their environment by governments or developers.

4) P2P Urbanism relies on available open-source knowledge, theories, technologies, and implemented practices for human-scale urban fabric that are free for anyone to use and review.

5) Residents have the right to implement evolutionary repositories of knowledge, skills, and practices, which give them increasingly sophisticated and well-adapted urban tools.”

Discussion of the definition within the context of the New Urbanism movement, by Nikos Salingaros et al.:

“A new generation of urban researchers has been deriving evidence-based rules for architecture and urbanism, using scientific methods and logic. These rules replace outdated working assumptions that have created dysfunctional urban regions following World-War II. A body of recently derived theoretical work underpins human-scale urbanism, and helps to link developing architectural movements such as the Network City, Biophilic Design, Biourbanism, Self-built Housing, Generative Codes, New Urbanism, and Sustainable Architecture. Open-source urbanism allows active users to freely adapt and modify theories, research, and practices following proven experience and based upon their specific needs and intuitions. This collaborative scientific approach based on biological and social needs supersedes the twentieth-century practice where an “expert” urbanist determines the form of the built environment based upon unprovable and “secret” rules, which are often nothing more than images and ideologies. Unfortunately, those unprovable rules were claimed to be “scientific” since they maximized vehicular speed and building density, even at the expense of the residents’ quality of life.

Peer-to-peer urbanism is applicable across a wide range of implementation scenarios benefiting from various degrees and forms of user participation. The most “formal” instance assigns the responsibility of constructing urban fabric to professionals, who however apply open-source guidelines and work together with end-users to develop the design. Even in this instance, which is most congruent to existing practice in the wealthier industrialized nations, design is carried out jointly and collaboratively. We avoid the current practice where a centralized power concerned only with ensuring that each part is working according to a rules schedule eliminates all external input. The other end of the peer-to-peer spectrum occurs in “informal” building, where professionals who are trained in open-source urbanism act mostly in an advisory capacity to guide citizens primarily responsible for both design and construction.

Researchers working within New Urbanism have developed the “Smart Code”, a comprehensive form-based urban code that can be legally implemented to replace the post-war modernist codes now legislated into practice in almost all the developed countries. This code is free for downloading. The “Smart Code” is also open-source, since it requires “calibrating” locally, a task of adapting it to traditional (i.e. pre-war) urban dimensions for those who wish to implement it. Unfortunately, many regions refuse to revise their modernist urban codes that are the opposite of the “Smart Code”.

Throughout history, “human-scale” urban fabric was always designed by people to fit their bodily dimensions, to accommodate their everyday movements, and to feed their sensory system and basic human need for socialization and interaction. With industrialization, architects and planners turned away from these geometrical mechanisms for building social structure to instead impose a visually empty, banal, and lifeless environment built with spaces and dimensions that are far larger than the human scale. Since then, a visually sterile gigantism has become the goal of a false urban modernity.
P2P Urbanism begins with spontaneous owner-built settlements. Rather than being a threat to formal urbanism, we see user participation as containing an essential ingredient of human-scale urbanism.

The architect and software visionary Christopher Alexander anticipated P2P Urbanism by writing the book “A Pattern Language” in 1977. He and his co-authors launched the idea of the right of citizens to have a say in designing their own environment, and also gave an open-source methodology for doing so: the 253 “Patterns”. These Patterns were not offered as a final word on design, but as working documents that could be adjusted and supplemented as needed after further research. So far, the Patterns have helped in two ways. First, as a diagnostic tool for judging whether a design — proposed or built — is adaptive to human use by whether it satisfies or violates the relevant Patterns. Second, in providing an essential tool that, when combined with an adaptive method of design, will help to produce an adaptive end result. (The Patterns are not a design method per se, and their application is described in “Principles of Urban Structure”. Also, despite their original intention of being “open-source”, the Patterns have remained unchanged since their publication).

Similarly, communicative-action planners have sought to re-discuss rational, scientific urban planning by advocating the need for better and truly engaged democratic participation. Rather than being only a science — and one that was badly misapplied up until now — urban planning should be understood as a communicative, pragmatic social practice where planners need to get their “hands dirty” so as to facilitate intercultural dialogue and implementation.

Even in a large project such as a hospital, airport, or Art Museum, it is very often the case that the design is arbitrary and sculptural rather than functional. The users were not sufficiently involved in the design, nor were Patterns developed and applied towards the appropriate uses. This is the reason why some of these extremely expensive buildings range from not being optimally functional, to downright dysfunctional, and detract from instead of contributing to the urbanism of the region in which they are inserted.

A separate strand for reflection comes from urban activism and transdisciplinary urbanism. Here, innovative thinkers have sought to contest classic and market-led urban planning and policies. Moving beyond the purely physical form-oriented aspect of urbanism, we are beginning to emphasize the political and social interpretations of urban environments. Artists, designers, and activists have cooperated with local stakeholders to claim alternative forms of democratic participation (full citizen participation, etc.) and improve the human quality of urban living.

Recent developments in information and communications technology are having an impact on P2P Urbanism. The free software movement, thinkers who are establishing a new domain of open-source productions freed from the restrictions of copyright, and the peer-to-peer network emerge from the World-Wide Web and re-examine the basis of closed-source thinking. The Wiki format coupled to the idea of Patterns brings the approach to city building back to genuine human needs. The Internet has made possible an open-source environment, thus challenging the obscurantist wave of “experts” and copyrighters who drastically limit both choice and innovation.

In the XXI century, new architectural movements, socially-engaged urban planners, innovative urban theorists, and online/offline P2P communities are coming together to challenge the established post-modern professional and architectural academic environment — the latter dominated by the belief that a few single demiurge-architects can determine urban dynamics. The definition and ideals of P2P Urbanism are constructed from the bottom-up. This process takes scientific results and theories on human biological and social needs and adds them to the on-the-ground experience of a myriad of actors and agencies (architects, urbanists, small firms, professional studios, NGOs, social workers, etc.) that are confronted daily with urban problems on the micro- scale. P2P Urbanism is now in continuous development, and merges technology with practical experience in a way that is innovative, open, and modifiable.

Beyond its obvious socio-political implications, P2P Urbanism means to establish a framework for sustainable built environment in the following sense. The ability to adaptively shape the urban fabric allows its residents to actively participate in its growth. This endows emotional ownership to the place, coupled with the responsibility to care for it and love it. A collective vision — whether generally shared or embodying a healthy diversity — makes it possible to connect to living local traditions and to better resist anti- urban forces imposed from the outside by systems of power uninterested in the inhabitants, the culture, or the unique specificities of the place. Often, the answer involves re-kindling the local building tradition that has been suppressed by outside developers implementing a generic industrial model.

The world’s housing problem can only be solved by channeling those same forces that generate informal settlements. Bottom-up forces arise from a natural need to use available materials, to build the most physically and emotionally comfortable human- scale environments, and especially to weave the urban fabric so as to nurture ordinary life on the street and in urban spaces. P2P Urbanism, therefore, is not just about design; it is about enhancing and supporting the energy in informal settlements by providing P2P services of all kinds. We will also develop the idea of social credits as a possible way for governments to recognize and honor the social capital of informal settlements. A community that is providing support to its own members and the rest of the city would earn “social credits”, which could be traded a bit like carbon credits for building material, infrastructure, or any thing else the community needs. This approach makes informal settlements not just recipients of what government needs to do for them, but it puts communities in a stronger position to negotiate what they want on their own terms.

After the work of Edward O. Wilson on Biophilia, we now know that human beings react positively to the biological information in their environment and to specific types of complex mathematical structures such as fractals. Thus, the need for a certain type of structural complexity in our surroundings is not simply a matter of aesthetics but a key to our physiological wellbeing. Alexander, and other researchers following his lead, identified those precise structures that generate a healing environment. P2P Urbanism is intrinsically biological, in the sense that it learns from nature and from living processes, and follows as an unintended complement to natural morphogenesis. It is impossible to follow this process without keeping in mind the problem of “objective science” and a critical envisioning of subjectivity, real human needs, goals, and meaning.

A new synthesis between consolidated architectural and urbanist thinking and peer-to- peer urbanists is arising from the failures of a political approach to urbanism, and this will allow us to plan for a better urban environment in our future.”

    Estimado Rafael,

    Después de la Conferencia Internacional en Berlino, hemos decidido de traducir todo nuestro trabajo sobre “el urbanismo entre pares” en castellano. Ve esta página:

    La definición ya está hecha:
