PERCEPTION MANAGEMENT: Increasing Density Natalie Mccorkle 2005
Brisbane’s population is forecasted to grow from 2.65 million to 3.7 million by 2026, requiring 550,000 new dwellings. To discourage sprawl and preserve open space, the South East Queensland Regional Plan’s Urban Footprint recommends that new growth take place as compact infill development, increasing residential density in key areas with adequate infrastructure.

However, although the majority of residents agree it is necessary to increase Brisbane’s residential density, many feel threatened by the region’s increasing urbanization. A survey of community response to the Urban Footprint demonstrates that higher levels of density are equated with slums, increased criminal activity, and the loss of privacy as well as individual and communal space. Density, therefore, is perceived as a spatial threat and an indicator of social and economic decline. A factor contributing to the city’s residents’ feeling threatened by increasing density is that unlike most cities, 70% of Brisbane’s dwelling stock consists of detached single-family homes, which predisposes a stronger desire and expectation of spatial privacy. The traditional regional house, the Queenslander, is characterized by a low, horizontal massing with a generous overhanging roof. The basic elements of the Queenslander—roof, interior, land, and veranda—interact to create zones of public and private space. The roof is a shielding element providing shade and protection. The interior of the house is the private zone. The land constitutes multiple zones; for example, the house is typically raised on stumps, creating an additional protected outdoor space. The veranda is a transition element facing the street regardless of the sun orientation: “A veranda is not part of 1 Analysis of Residential Density and Housing Typology 2 Queenslander: analysis of the roof element 3 Queenslander: analysis of the interior element 4 Queenslander: analysis of the Verandah velement 5 Queenslander: analysis of the underside velement 6 Identifying and reinterpreting the public and private zones of the Queenslander House 7 Diagram of the interaction of people and place and the creation of public and private space 8 Identifying and reconstituting the basic elements of the Queenslander house 9 Proposal

I want to preserve the position that the modern city can be both beautiful and yet a product of unsentimental exactitude. In other words, the age of the Master Plan has exhausted itself; it was a transition helping cities survive in an age of doubt. Cities today are thriving, and more and more people are living in them. We need to develop a new understanding of the city, one that can, once again, only be brought out once stripped of sentimental associations. To repeat: CIAM of the 1930s and Master Plan urbanism of the 1970s were determining moments in the history of how we understand the city, transitions into the more full-scale modern metropolis of tomorrow. The first attempted to cut away lingering attachments to a still agrarianbased notion of the city, a city with a symbolic core, industrial ring, and agrarian hinterland. The Master Plan compromised that model by returning to the conventions of a core, surrounded not by industry, but by suburbs. If from the first Radiant City there was something that can be redeemed, this is also true for the Master Plan; it taught an important lesson, despite itself: the city was just as much image as substance. The energies behind the Master Plan were commerce and tourism, and by the 1980s, this interplay became a key element in the urban ideal. The two poles of our new city are thus science and image.

The New Radiant City does not even have to determine all that is built or even how it is built. The New Radiant City does, however, have to commit itself to the principles of our age. The new city is both a scientific project and an imaginary one. It is confirmed in the languages of knowledge and projected in the images of the mind. We should recategorize Construction, Economy, Circulation, Environment

Our categories are purposefully abstract. Unlike Le Corbusier’s, which had man at the center, albeit a modern man, ours focus on the larger transhuman forces that now define the science and image of cities. This is not because we reject designing a city from the point of view of human experience, but because we think human experience finds itself within, around, and through these transhuman forces. For a century, industrialization has broken up the city and been responsible for its disintegration into slums, industrial quarters, and urban peripheries. But

the house…It is what allows traveling salesmen with one foot on the step to heave their cases over the threshold and show their wares with no embarrassment on either side, no sense of privacy violated…Verandas are noman’s land, border zones that keep contact with the house and its activities on one face but are open on the other to the street…’ (David Malouf, 12 Edmondstone Street) The premise behind this project is that by reinterpreting and manipulating the traditional Queenslander elements, density can be increased while its perception is minimized. Indeed, perception management, a concept introduced by the U.S. military, is defined as an action to convey or deny select information and indicators to influence emotions, motives, and objective reasoning. Perception management can use deception to influence behavior and attitudes. Therefore, this concept, applied to architecture, can alter the perception of the built environment, the boundaries of which distinguish public and private space and define how people interact with each other. Density may be increased, and its negative perception managed, by manipulating these boundaries. Shared public spaces can reinforce community interaction. A sense of privacy can be fostered by using buffering devices such as landscape and interlocking elements of open and closed space. Reinterpreting the Queenslander elements, at varying levels of density, can reinforce a sense or privacy, autonomy, and community.

we can project something better by renouncing the dualities that were used to hold the city together in its artificiality: work-leisure, habitat-villa quarter, and coreperiphery. The suburbs after WWII were a search for a new, alternative coherency, more integrative and more network/image based. But the suburbs were not urban. The new cities of tomorrow will have many of the qualities of both the suburb and the city. From the point of view of cities, the core can be abandoned, but not density. From the point of view of the suburb, the shopping malls and the highways can be abandoned, but not retail marketing and the need for mobility. Construction, Economy, Circulation, Environment are not separate categories. Each modifies the others, and in this, our New Radiant City is different from the Radiant City of old. There is no single place where “circulation� takes place, for example. Though for practical reasons, we might put traffic under the heading of circulation, one has to remember that money circulates; that human waste circulates, and that even politics circulates. Imperatives 1. The old view of city was through the differentiation between city and hinterland. The mountains were for recreation, the flat lands for farming, and the city for global distribution networks (i.e. trains, ships, and airplanes) and their regulators (government). In the cities of tomorrow the mountains belong to the tourist industry, the flatlands to agro-industry, and the city to distribution industries. The entire landscape is regulated. This already defines Switzerland, and indeed most of Europe, where there is not a single natural tree line. 2. The cities of tomorrow will not have large centralized cores that house the financial district and condos for the elite. There will be financial districts, but they will not define the symbolic core of the city. 3. The cities of tomorrow will have to integrate both large-, mid-, and small-scale production into effective ways of circulation and control. 4. The cities of tomorrow have to incorporate trash and waste disposal as part of their form-economy. These cities will not export trash to third-world countries or to distant places. Cities of tomorrow will generate their own landscape of hills. Landscape artists will work with urban designers to accommodate the hills. 5. The cities of tomorrow will be designed with wind farms and sun-powered generators —along highways or in parks. 6. Urban branding and urban design will be equal in importance. Tourism already is a US $6 trillion industry globally. Cities will
