In 1993 the Victorian State Government Minister for Major Projects, the Hon Mark Birrell, established the Bundoora-Mont Park Reference Group (or BMPRG) whose objectives were to provide a range of recommendations to do with ecological, heritage and traffic issues, so as to establish a set of ‘building blocks’ for the future planning and development of the area.
The members of the BMPRG represented the interests of a large range of community groups and entities including State Authorities, the La Trobe University, Local Councils and Progress Associations, as well as Action and Conservation Groups and Societies. The BMPRG looked at three specific regions in and around the Mont Park area, namely the Bundoora Repatriation Hospital area, the Larundel/Kingsbury Centre area, and the area that the Springthorpe Estate was built on, i.e. the Gresswell-Mont Park-Plenty area (which is the focus of this article). 
In 1995, as much of the Mont Park Hospital precinct had either already been, or was about to be closed/decommissioned, the BMPRG presented its recommendations to the State Government in the form of a document titled the ‘Master Plan for the Future’. 
In 1996 the Victorian Government, through the Office of Major Projects, produced a document titled ‘Mont Park/Plenty – Call for Expressions of Interest’ wherein it invited companies and groups from the development industry to consider managing the staged redevelopment of the 74 hectare Mont Park Hospital site.
This document sectioned this 74 Hectare area into seven distinct precincts, namely the Central Parklands, Plenty Hospital (South), Plenty Hospital (North), Gresswell, Macleod, Waiora Road/Cherry Street, and Mont Park/University. Each precinct had its own natural characteristics. This ‘Mont Park/Plenty – Call for Expressions of Interest’ document referred to how the developers of the site will require a “…sensitive and innovative development proposal that draws on its many strengths and attractions.” 
The Master Plan envisaged 600 to 800 new dwellings in the Gresswell-Mont Park-Plenty area (depending on the extent of La Trobe University’s requirements for the site) and it noted that the University had already begun utilising a number of the buildings for teaching and accommodation purposes at that time. 
In August 1997, following a competitive process, Urban Pacific Ltd (or ‘UPL’) was granted preferred developer status. UPL was a wholly owned subsidiary of Macquarie Bank Ltd and specialised in the creation of comprehensively planned residential communities. 
UPL’s stated vision for the development of the Mont Park site was to “…create a commercially successful development, widely respected for its environmental and heritage sensitivity, innovative planning, housing choice, and exacting quality standards.”
The landscape architectural practice of Mark McWha Pty Ltd was initially engaged in June of 1999 to prepare a landscape master-plan to support the earlier development-plan submission lodged by UPL. Ongoing liaison with the City of Darebin and the La Trobe University also followed, that then saw approval of the UPL master-plan by the City of Darebin soon after. 
This master-plan included the obligation to retain all ‘Heritage Listed’ aspects of the former Mont Park Hospital precinct, as well as a number of other ‘heritage sensitive’ aspects of the site. To this end a number of former Buildings still adorn the area and have found themselves new life as either accommodation, office or teaching facilities. [See Hyperlink here to the ‘Mont Park Buildings’ page within this website].
In July and August of 1999, arboricultural consultants, TREElogic, in association with Mark McWha Pty Ltd were engaged to provide a thorough arboricultural assessment of all the trees on the Mont Park development site.
Great importance was placed on the retention of the fundamental character of the Mont Park landscape, and in particular the preserving of many of its majestic trees (Eucalyptus/River Red Gums, and Acacia/Wattle trees etc) as possible. Therefore an audit of every single tree (numbering 4,338 trees) was conducted, and an assessment made and a report provided on each tree in terms of its potential to be retained (where possible, including those located on residential blocks). The audit also looked at the important issue of ongoing tree management.
The landscape architect & urban design practice of Taylor Cullity Lethlean (or ‘TCL’) then took over from Mark McWha Pty Ltd and completed the detailed design of the Estate on behalf of UPL. TCL went on to be presented with multiple Urban Development Institute of Australia ‘Awards for Excellence’ in 2003 and 2004 for its Urban Renewal, Residential, Master-planned, and Environmental Excellence Projects relating to its work on the Springthorpe Estate Project.
Cox Architects and Planners were the Town Architects engaged in the late 1990s to define a ‘building envelope’ on each Lot across the Estate that would ensure that most of the existing trees were retained. Their ultimate goal was to design the Springthorpe Estate layout in such a way as to “…create a unique environment featuring exclusive designs, natural setting and an integrated solution to housing.”  and 
Throughout the duration of the project, Paroissien Grant and Associates Pty Ltd undertook all of the survey works including all of the plans of subdivision. They later undertook the civil engineering design for a few of the development stages as well.
The first plan of subdivision was registered in December 2001 for about 20 Lots (of land) near Cherry Street at the Waiora Road entrance to the Springthorpe Estate, and the first homes in the Springthorpe Estate began being built at this location soon after.
Building and construction continued somewhat furiously in and around the Springthorpe Estate in stages from about 2002 onward for the next 5 – 6 years.
A centrepiece to the overall development was the fairly unique concept of a Springthorpe Estate Country Club which by necessity required the creation of an Owners Corporation to manage the asset that is the Country Club, Pool, BBQ, Gym and Tennis Court area as well as coordinate its accessibility and ongoing finances. It is noteworthy that the Country Club (as it is known today) was used as a Display Centre during the development of the Estate.
In 2007 Urban Pacific Ltd released the last 60 blocks of land as part of its ninth and last stage of land release.
These last 60 blocks were on the eastern side of Gresswell Hill alongside the Gresswell Forest and were advertised as blocks with views spanning from the Macedon Ranges to the Dandenong Ranges from ‘one of the highest points of metropolitan Melbourne’.
