Masterplan
16
The ongoing growth of Macquarie Park to become Australia’s 4th largest CBD by 2031 is largely due to its large technology, commercial and industrial precinct which feeds from Macquarie University and large retail centre. Residents of Ivanhoe Estate benefit from the large public transport networks which are strengthening links to the greater west, Parramatta and Sydney CBD. With the redevelopment of Ivanhoe Estate, there is an immense need to conscientiously address mixed tenure communities in a high-density environment which caters for social housing and the private market.

SITE ANALYSIS
1
We often lose the human scale in high density developments, with taller buildings and a ground plane that caters more for the car than for pedestrians and cyclists, which produces public spaces that are lacking the spatial qualities for wholesome community interaction. The proposal for Ivanhoe Estate seeks to bring back the balance of privacy and intimacy in the public spaces that surround the buildings. Removing the congestion of a vehicular intersection from Ivanhoe Estate to Herring Road enables its interface to be much more focused on providing essential forward-thinking amenities to its residents such as a Light Rail stop, bus stop, pedestrian walkway and cycleway. These provisions (reinforced by the integration of nature via Shrimpton’s Creek Pedestrian Link to the south) encourages a more active community which in turn improves the wellbeing and health of its residents. Shifting the dependence from privately owned vehicles to a robust public transport network capable of large growth is a more economically and environmentally sustainable and is the direction Australia’s large urban centres should be aspiring to become.

transport hub
The importance of Herring Road as a node for public transport in the future demands a link free of heavy vehicular traffic in and out of Ivanhoe. A light rail, bus lane, cycleway and pedestrian pathway links Ivanhoe Estate with greater transport hubs in Macquarie Park and Parramatta.

Individual Tower The development of this building is a justification for the spatial arrangement and distribution of density in the masterplan. Selection of the tallest building with the largest footprint on the site gestures to an attempt at redefining the possibilities of a mixed-tenure community in high-density developments. Feeding off the primary north-south roadway and pedestrian link that runs through Ivanhoe, the building is situated at the lower end of the site and backs on to the preserved Ironbark-Turpentine Forest. It has a direct connection with the Shrimptons Creek Pedestrian Link and the accompanying parklands and is an ideal example of the possibilities of micro-industry and retail opportunities at ground level which engages the greater community whilst providing job opportunities within the site. A playground enclosed by a low wall in the forecourt to the building gives parents the assurance that their children are safe and are within close distance of supervision during visits to the commercial tenancies within the podium.
CONCEPT
Hayden Co’burn
Reinforcing the human scale in the vertical neighbourhood is achieved by fragmenting the tower into 4 breaks of 5 storey ‘blocks’ which encourage the idea of micro-neighbourhoods. Interaction is encouraged through the open-air atrium and the areas which people can gather such as the communal barbecue areas on every alternating level. This open air atrium opens to the northern sun and invites a natural flow of air into the spaces.

BUILDING MASS
To fully embrace the concept of a mixed-tenure community, the design calls for no allocated floors or parts of the building where those that require social housing are concentrated or left to feel as if they are isolated or different from others. A floor plate which involves different types of housing stock encourages pollination of ideas, community interaction and importantly, diversity. Each unit has a dual purpose which satisfies both social housing and the private market. Demand for 1 bedroom and 2 bedroom apartments satisfy the demand of the social housing demographics but encourage young professionals and small families to live side-by side with those that may be in dire circumstances and could benefit from the positive interactions.
