Urban Decay, Renewal and Consolidation By Sheridan and CHloe


Consolidation: Urban consolidation is defined as the policies and programs designed to increase population densities in urban areas in order to make more efficient use of existing infrastructure and to limit urban spread into surrounding rural areas.

Urban decay: The deterioration of the urban environment. It occurs when urban infrastructure falls into disrepair and buildings are left empty for long periods of time

Urban renewal: The redevelopment of a dysfunctional urban infrastructure (i.e. buildings) so that they better meet the needs of people.

An example of Urban decay


Urban Decay and Renewal

- (Until mid-1960s), Sydney’s inner city with the deterioration of residential areas. In particular, nineteenth-century working-class housing and the decline in inner-city investments with suburbanisation of manufacturing, warehousing, retail, office-based activities.

- (Since 1960s), due to the process of gentrification (the renewal of inner-city residential precincts through renovation and occupation of younger, higher-income earners in high-role occupations) residential deterioration has been reversed.

- (During 1980s - early 2000s), global economic restructuring has acted to promote reinvestment in the inner-city, in particular high density and low density areas. Some initiatives have been large scale Eg. In Darling Harbour Pyrmont - Ultimo which was one of the world's largest area of renewal.

Examples of Urban Decay and Renewal can be seen in Rhodes, Glebe, Balmain, Newtown and is now reaching into the wider areas of inner west

Apparent around city’s suburban railway stations and more desirable residential precincts. Processes involve demolition of a row of three to four detached dwellings and their replacement with townhouses, villas, duplexes and apartment blocks. In more sought after locations, land is more expensive, multi-story apartments are constructed. Inner city locations, old industrial sites and land occupied by port facilities are being redeveloped and consolidated into higher density residential and commercial precincts.

Examples of this can be seen int eh Ku-Ring-Gai council area where the local council are attempting to condense and build high rises due to high housing demand in the area.

CASE STUDIES - Green square, Millers Point, Barangaroo

  • Urban Decay, renewal and consolidation in Green square, Millers Point and Barangaroo
  • 14 hectares
  • $8 billion combined investment
  • 6,800–8,600 projected working population
  • $540 million City of Sydney investment.
  • Central Sydney's major urban renewal projects can be assessed on City of Sydney’s website under ‘Urban renewal projects’ and ‘City Improvements’
  • Carlton United Breweries site, green square and redfern precinct
  • supervised by the state government
  • Barangaroo - formerly known as Darling Harbour east

The construction of Barangaroo commenced in 2012, formerly known as East Darling Harbour. It was previously a containerisation of shipping with over 22 hectares of concrete covering the area. The site became unsustainable as a port and unusable for the ships as shipping technology had changed so much. This caused the land to suffer from ‘urban decay’ which triggered the government to produce a new concept for the urban renewal of Barangaroo. The concept, which was approved in 2007, was to split the current site into three sections. The three sections consisted of Headland Park, Barangaroo Central and Barangaroo South. Minor amendments have been made to these initial plans throughout the years of production such as improvements in eco-friendliness, improvements to the safety and sustainability of buildings and the removal of Sydney Ports Harbour Control Tower. These plans also involved urban consolidation as new homes and apartments were constructed in Barangaroo South. The impact this had was increase in population and increase in job opportunities. These plans also included a hotel.
