CHINA CITY
Click to edit Master text style Cities have evolved over centuries to adapt to our social and economic and to accommodate a range of building types. Click to edit Masterneeds text styles Advances in technology such as the elevators, motor transport and subways have enabled the city to become ever more dense, efficient and vibrant. There is now increasing pressure for cities to accommodate large-scale mixed commercial buildings whilst also responding to a demand for increasing density and efficiency. This essay suggests that cities may best respond by densification around planned hubs of mixed usage development, that these hubs require enhanced infrastructure and that they might be designed to be porous and adaptable as cores of our urban fabric. 03/10/2015

In the last 30 years urbanisation has helped lift half a billion people in China out of poverty. Much of this urbanisation has been led by cities acquiring land at low prices from farmers and funding infrastructure from Central Government loans. There has been no centrally coordinated approach or plan for urbanisation.

The by products of this uncontrolled urbanisation are: • Inefficient Urban Sprawl • Rising Social Inequality • Over building of expensive infrastructure • Pollution exacerbated by longer commutes

1. Happiness Over Wealth 2. Low Carbon City 3. Compact City 4. Smart City 5. Inclusive City
03/10/2015
Click to edit Master text style Six Key Drivers of the New Policy: -
1. Land Management Reform – More efficient land use. Strong property rights and compensation for farmers. Market driven land pricing. Legal limits on the Click to edit Master text amount of styles rural land requisition. 2. Reform of Hukou System – Fair wages and equal access for all to public services to create a mobile work force. 3. Sustainable Urban Finances – Local authorities to fund urbanization through property taxes and higher charges in lieu of Central Government loans. 4. Reform Urban Planning – Market driven land pricing will encourage heavy industries to move to secondary cities. More flexible land zoning and smaller plots to improve land efficiency. Coordinate and link urban modes to transport to reduce trips, congestion and pollutions. 5. Improve Environmental Controls – Enact existing legislation by enforcement, taxes, and incentives. 6. Improved Local Governance – Incentivize local officials to achieve efficient, inclusive urbanization, Local Governments management and accounts to improve and to be transparent. 03/10/2015

If the city is a complex network of infrastructure, buildings and spaces then it encompasses a far greater complexity of society and culture. These complex networks have a huge ability to accept accretive growth and change within their established framework.

无中生有 “Starting from Scratch” Facing the wave of fast Chinese urbanization, architectural practice is frequently challenged by chaotic and featureless site conditions. Behind seemingly empty context, there rests rich historical, social and cultural threads. Architects might explore culture-driven design strategies, which could guide their designs in China's market-oriented urban developments.

千篇一律 Efficiency and Diversity In the modern era China has witnessed the victory of mass production. Despite various narratives, there are similar stories behind the legend of every city's bursting development. Economic interests overwhelms social values. The vast effort of constructing concrete wonderlands could not offside the inability of creating diversified identity, which results in unfulfilled experiences, unstable social ecology, noncompetitive culture, and restrained creative possibilities.

过犹不及 Quantity and Quality As a primary driver of economy, urban growth and housing booms are transferring China into a consumer's paradise. In one aspect, the increasing supply of private property has enhanced the physical conditions of inhabitation, in another aspect, the decreasing arable land is challenging the base line of human survival. A balanced land development has to be considered to secure a true balanced and lasting social stability.

朝生暮死 Ephemerality and Metamorphosis Besides numerable newly built cities in China, mass deconstructions are also occurring at an increasing rate. It is not rare to see large building designed to last over 50 years but demolished less than 20 years after birth. Like electronic products, architecture has become ready-made evanescent application to be disposable for upgrading. Seldom are these opportunities given for any in-depth cultured development to thrive in this unsustainable environment.

温故知新 Lost and Found We are fortunate that the short history of modern urbanization has not totally overshadowed the long lasting heritage of Chinese civilization. One can recognize the resilience of traditional culture and use it to transform and build a cultured and more progressive society. Critical research and thoughtfulness could lead to future innovation in different scales.
