THE URBAN SHELF
â€œOur cities must be places, where human beings live fulfilling lives in dignity, good health, safety, happiness and hope.â€? Habitat II Conference Declaration on Human Settlements, Istanbul 1996
MISSION STATEMENT by Dr. Paul Friedli Transit Management Group, Schindler Ltd. This is the third in a series of books that Schindlerâ€™s Transit Management Group has produced in an attempt to provide specific answers to the very severe problems projected to occur during the next phase of urbanization across the globe. The first book, Future Cities began by exploring alternatives to the accepted design configuration of virtually every building in the urban environment. One of the concepts introduced was the Urban Shelf, a new approach whereby a series of platforms provide a structure and infrastructure into which complexes of housing retail and public spaces can be deployed. In our second book, Urban Shelf, Modul Hashtag we examined a specific case of the Urban Shelf which we termed the Hashtag, based on the idea of an urban neighborhood centered around a courtyard. When it came to developing ideas for the third book in the series, it became increasingly obvious that the Urban Shelf idea had generated considerable excitement in the architectural, developer and urban planning communities. It was therefore decided to undertake a much deeper exploration of the potential of this approach to utterly transform city landscapes of the future. And so we come to The Urban Shelf, a book that takes a very frank look at the problems endemic in current cities and shows how this new approach could provide novel and extremely exciting solutions. In it we do not shy away from controversy and we do not expect that everyone will agree with all that is written. But the fact that you are considering reading it shows that you share our passion to raise the quality of urban life for our children and grandchildren - and that is the important thing. Thank you for joining us on this journey so far. We hope that the debate will continue and that, as a result of challenging people who are in a position to orchestrate change, we will make a real difference to the living standards of all city dwellers in the years ahead.

MOBILE URBAN MORPHOLOGIES By Max Schwitalla & Oke Hauser
The 20th century has been marked as the beginning of the urban age. Cities represent the core hubs of the global economy, innovation and governance services. As in the era of the anthropocene, cities constitute the primary condition for human life, it is time to have a closer look at the spatial drivers and dynamics: Urban fabrics have always been the spatial consequence of the negotiation between architecture, the immobile space and infrastructure, e.g. the space for mobility. The 20th century has been dominated by the massive spread of the automobile and the rise of the elevator as the main urban mobility infrastructure. Both mobility systems defined the dimensions and scales of the modern city fabric: Promoted by the automotive industry the car stretched the city into an endless horizontal plane characterized by flatness and a two-dimensional sequence of privatized plots waiting to be occupied by the citizensâ€™ desire for individualism and freedom. The result is often an extremely inefficient urban fabric where around 50% of the urban area is wasted by mobility infrastructure. Next to the economic and ecologic problems (massive infrastructure costs, high CO2 emissions) social problems (lack of community) were linked to this process. The vertical dimension seemed to be the only way out of this dilemma: The generic elevator core based tower promised to be the solution for further urban densification. The technology that made this possible became practicable in NYC in the 1850s. Since then, the elevator became a global urban commodity and literally flipped the social vertical arrangement upside down while the elevator cabin represents in essence the contemporary ambiguous urban atmosphere of intimacy and anonymity simultaneously.
Until today, vertical densification seems to be the acknowledged solution to the massive urban growth in the 21st century, but in recent neo-liberal urban markets the elevator core based tower was doomed to sheer speculation on multiplied privatized space! Efficiency and profit maximization lead to endless repetition of insular stacked privatized space that dominates the stagnant public ground: the main space for urban qualities like human encounter, social interchange and personal freedom is by comparison continuously shrinking. Consequently the urban experience is increasingly characterized by separated and isolated personal spheres. It is evident that we can not rely anymore on architectural and urban typologies from the last century. And as we experience the economic, ecologic and social limits of the urban models of the 20th century centered around mobility technologies, we should ask ourselves today: How will the emerging digital mobile technologies and future urban mobility change our urban surrounding in the future? Is this a chance to generate urban environments centered around the human scale and needs rather than the ones of machines? We need to practice an urban design based on possibilities and inclusion not on efficiency and exclusivity! We need ongoing transformation rather than static predefinition. Inspired by usergenerated, open platform digital models we aim for a city of participation, communication and collective experience: Not only a Smart City but a city for the Smart Citizen!

EVALUATION a survey of the dynamics of vertical urbanism
Economic Dead End Form Follows Finance
The urban verticalization represent the global dynamics of neo-liberalism and privatization within urban markets. The inferiority of local nonâ€“market mechanisms favors tall housing towers to act as the local fuel for the global financial speculation machinery. Architecture turns into an investment asset and accommodates the global eliteâ€™s capital instead of the cityâ€™s people. By constantly increasing the maximum allowed FAR (floor area ratio), slenderness becomes the new beau ideal in highrise design and vertical exclusivity is stretched to the absurd. The vertical ascension of capital into the skylines transforms the urban identity into a marketing tool within the global cities competition for investment, tourism and highly educated elites..
Skinny Highrises Hong Kong Slenderness
The term “Slenderness” is defined in the world of engineering by structural engineers as: A high-rise building is considered to be “slender” with a minimum of 1:10 to 1:12 ratio (width of the building’s base to its height).

The defining characteristic of the tall buildings in Hong Kong is slenderness as the city has more pencil thin towers than any place in the world. In the 1980’s, Hong Kong’s high land values combined with liberal zoning laws generated districts of extraordinarily slender and densely-packed apartment towers. Hundreds of speculatively developed apartment buildings reached the city’s permissible maximum FAR of 1:18.

Ecologic Dead-End City As An Ecosystem
The recognition of the city as an ecosystem becomes even more relevant as we enter the urban age of the anthropocene. Urban ecosystems have the same conceptual need for balance and life cycles as their natural counterpart. The dominance of build mass over unbuilt space, for example, creates various micro-climatic and environmental issues like the increase of inner urban temperature and the decrease of natural ventilation and therefore the emergence of pollution smogs. These changes in the urban micro-climate affect the comfort and quality of life, the highest value in urban environments. Therefore the need to focus on a healthy inner-city climate will become even more fundamental. 42

The impact of the Urban Heat Islands (UHI) have been explored through various methods in the area of Singapore. Figure 1 shows in a satellite view the thermal differences between the “rural” and the “urban” areas. The “hot” spots are normally found on exposed hard surfaces in the urban context, such as the industrial area, the airport and the Central Business District (CBD). The “cool” spots which are mostly observed in the large parks and the landscape in between the housing estates.

In Singapore, where dense urban structures result in the UHI phenomenon, rapid population growth and the expansion of city development are expected to reduce the quality of urban life. 46
Social Dead-End Complexity as quality
The quality of life within the urban context can be measured by the capability of its inhabitants to encounter complexity. A high quality city is characterized by the inclusion of different classes, ethnicities, and lifestyles. The public space as a platform for diversity, accessibility and personal freedom becomes the highest urban value. In the neo-liberal city, characterized by its shift towards privatization and economic mechanics, those spaces are shrinking comparatively. Spatial segregation and social isolation throughout all classes is the consequence and the typology of the generic high-rise as the efficiency machine is the inevitable architectural product of these tendencies.

Smart City vs. Smart Citizen Spatial & Social Implications of Digitalization Most smart city visions focus on the aspects of technology, buildings, infrastructure and vehicles instead of starting with the human perspective. But the city is first of all a place for people and made by people. As social individuals, people create cities as places where they get together with other people, to create culture, to build wealth and to raise new generations. Buildings, squares, infrastructure and vehicles should serve as the enabling hardware.

MOBILITY Seamless personalized urban mobility landscape
The smart city vision, with efficiency as the main marketing notion, neglects a main part of urban life: we create the city to meet people coincidentally, to play, to love, to rest and to enjoy the sunshine. As we learned from social media platforms: once established, active citizens are generating their very own networks and environments. The â€˜smart citizenâ€™ could transfer these dynamics and functionalities from social media onto the physical and spatial engagement within the urban fabric. This way the city will remain a dynamic organism modeled by wishes, needs and desires of its people. That city could be become a model of a collective experience as the synthesis of individual and public needs.

Conceptual Examples / Adaptiveness
The URBAN SHELF can fit into various urban spaces and is able to perform on various economic bases, from developing to first world backgrounds because dwellers can create the housing units individually according to the given resources and options. The social adaptiveness is given by the participation of the dwellers in the building process and the gradient of predetermination.
This depth of planning can range from a DIY completion by the users to a catalogue of predefined or even prefabricated unit sizes, materials etc. The layered flexibility of the URBAN SHELF is a new concept for adaptive urbanism, that is able to react to the different challenges and problems of global urbanization by generating a new level of sustainability and social interaction.
