Leading lights : the promotion of garden suburb plans and planners in interwar Australia

This thesis explores interwar town planning in Australia, focusing on the period of large-scale urban expansion in the 1920’s. It problematises aspects of Australia’s urban planning history, particularly the 1920s ‘garden suburb. It also investigates the question of the use of international planning ideas in Australia, and the assertion or creation of authority by the Australian planning movement. The thesis additionally investigates the use of authoritative planning rhetoric for commercial or creative advantage. The thesis argues that the majority of innovative planning projects in the interwar years took place in the formation and foundation of the garden suburb. It shows that the garden suburb – assumed in much planning history to be an inferior form of Ebenezer Howard’s ‘garden city’ ideal – has, in fact, a number of precedents in 19th century Australian suburbia, some of which were retained in 20th century commercial estate design. Much of the Australian town planner’s authority at this time required recognition and awareness of the interests and needs of the general public, as negotiated through land vendors. As Australians looked to the future, and to the US for guidance, they were invited to invest in speculative real estate development modelled on this vision. The thesis concentrates primarily on the lives, careers and work of the British-Australian architect-planner Sir John Sulman; the Chicagoan architect-planners Marion Mahony and Walter Burley Griffin; and the Australian surveyor-planner Saxil Tuxen. These individuals were among the most prominent planners in Australia in the interwar years. All designed Australian garden suburbs, and combined advocacy with practice in private and public spheres. The thesis examines images and personas, both generic and individual, of the planner and the vendor. It shows that the formulation of the garden suburb and design practices, and the incorporation of international elements into Australian planning, are important in the creation of planning practice and forms. It also outlines the way these continue to have significant impact, in diverse and important ways, on both the contemporary built environment and planning history itself.

Validating planning heritage : evidence and reasoning for national heritage recognition of the 'City of Adelaide Plan' and park lands

The Adelaide Park Lands and the ‘City of Adelaide Plan’ (1837), as prepared by Colonel William Light, have long been held up as an international precedent in town planning literature. The celebrated model, embraced by Ebenezer Howard to describe his Garden City theory, has several layers of cultural landscape heritage. The ‘Plan’, in recent years, has been subject to a rigorous investigation of its Indigenous and colonization evolutionary layers to inform moves to list the landscape as possessing national heritage status under relevant Australian heritage regimes, and more recently under the National Heritage List regime, as a pre-emptive strategy towards an eventual World Heritage nomination of the cultural landscape and ‘Plan’.

Master planned estates : parish or panacea?

Master planned estates in Australia emerge from two major directions: one aims to address the inadequacies of 1970s suburbanisation and the other comes from governments and developers seeking to realise alternatives. The very idea of master planning has a longer history, one that arguably dates back to 19th-century Utopian Socialism and Baron Haussmann's redesign of Paris, which involved a large-scale, comprehensive alternative vision realised by a sanctioned authority. Master planning thereby partakes of both utopianism and authoritarianism. These associations have infused the discussion and construction of Australian master planned estates rendering them both pariah and panacea. But research and my own experience suggests that they are far more panaceas than pariahs.

Green planning heritage/industrial nature : the park lands or 'regeneration reserves' of Broken Hill

Freestone (1989+) has extensively surveyed town planning visions and model communities for Australia, but one settlement has been forgotten. The significant mining settlement of Broken Hill in far western New South Wales does not figure in his thematic and historical analyses yet its park lands are so integral to its physical cultural legacy and human health that it warrants enhanced standing. In the last 2 years the Commonwealth has been considering the potential nomination of the municipality of Broken Hill for inclusion onto the National Heritage List principally due to its mining, social and economic contributions to Australia’s heritage and identity. A component in their deliberations is the Park Lands, or ‘Regeneration Reserves’, that encompass this urban settlement and its mine leaseholds. Within these Regeneration Reserves, international arid zone ecological restoration theory and practice was pioneered by Albert and Margaret Morris in the 1930s that serves as the method for all mining revegetation practice in Australia today. This paper reviews the theory and evolution of the Broken Hill Regeneration Reserves, having regard to the Adelaide Park Lands and Garden City discourses of the 1920s-30s, arguing that the Broken Hill Regeneration Reserves have a valid and instrumental position in the planning and landscape architectural histories of Australia.

Creative conservation and Balinese traditional landscape : scenarios for eco city concepts and culturally sensitive tourism development

Bali is internationally recognized as an island possessing a beautiful natural landscape as well as a unique culture. The natural qualities of its mountains, lakes, rivers, rice terrace fields with subak irrigation make Bali an important tourism destination. Cultural Tourism is integral in Bali’s tourism industry providing the basic capital for development1. The social condition of this society that is strongly characterized by religious beliefs, and its nature and ecology also supports this. The conservation and maintenance of this traditional landscape is often forgotten because of government agendas to implement cultural city programs aimed at encouraging tourism development. Despite this, the government is now supporting the program of ‘Bali toward Garden Island’, which aims to sustain the physical and cultural environment of the island towards conservation of its landscape. The implementation of this program includes attention to universal, societal and cultural values as unity indicators, of which the landscape planning of the Balinese characteristics and traditions cannot be separated. Landscape planning is integral in this initiative of character defining the region.

Globalisation is increasingly becoming one of the most important discussions amongst the Balinese people. It has become a national concern about the changes implicating Bali’s environment. Urbanisation, population growth, ribbon development, migration and consumption of energy are important imperatives and necessary evils for growing cities. These imperatives are creating the sprawl of building planning, development information, loss of open spaces, as well as the decline of the identity of cities. Places such as Denpasar City are struggling with increasing population at a rate of 1.94% per year that is causing increase in housing and public facilities demanded by both residents and ex-patriates. Thus land associated with the city has been lost to the rapid development of this cultural landscape.

This paper examines the Balinese traditional landscape and its role in encouraging tourism development that based on the Balinese culture and its ecology. The paper focuses on the planning of city landscape appearance characteristics and seeks to test and adopt the terms ‘creative conservation’ and ‘eco city concept’. By conserving the most important philosophy of the Balinese Tri Hita Karana Concept will better inform all aspects of city development in Bali. This study seeks to offer guidance for the legitimate use of landscape planning especially for city development in Bali.

Urban surface temperature behaviour and heat island effect in a tropical planned city

 Putrajaya is a model city planned with concepts of a "city in the garden" and an "intelligent city" in the tropics. This study presents the behaviour of the surface temperature and the heat island effect of Putrajaya. Findings show that heat island intensity is 2 °C on average at nighttime and negligible at daytime. But high surface temperature values were recorded at the main boulevard due to direct solar radiation incident, street orientation in the direction of northeast and southwest and low building height-to-street width ratio. Buildings facing each other had cooling effect on surfaces during the morning and evening hours; conversely, they had a warming effect at noon. Clustered trees along the street are effective in reducing the surface temperature compared to scattered and isolated trees. Surface temperature of built up areas was highest at noon, while walls and sidewalks facing northwest were hottest later in the day. Walls and sidewalks that face northwest were warmer than those that face southeast. The surface temperatures of the horizontal street surfaces and of vertical façades are at acceptable levels relative to the surface temperature of similar surfaces in mature cities in subtropical, temperate and Mediterranean climates. © 2014 Springer-Verlag Wien.
