Welcome to the community information website for 55 Coonara Avenue, West Pennant Hills. Here you will find information about the rezoning proposal, proposed community benefits and the latest news. You can also sign up for information updates.

Mirvac is proposing a new masterplanned community to replace the existing high intensity business park, nestled adjoining the protected bushland, where residents are connected to parkland and the future Metro Rail.


The proposal

The proposal aims to repurpose the existing footprint - currently consisting of office buildings, car parks and roads - into a family-friendly, residential community, in a protected bushland setting.

The proposed master-planned estate, which has been worked on from mid-2015 with Council, is made up of extensive open spaces, 200 houses, 400 apartment style homes, and community facilities. 

The plan is contained to the existing established development area, keeping intact and protecting the remnant forest, and the important bushland character.

The proposed homes will be architecturally designed and contemporary in style, designed to seamlessly integrate into the existing neighbourhood character while retaining and protecting the forest setting. The apartments are strategically located at the lowest portion of the site within the existing height limit, taking advantage of the natural topography.

2.493ha of open space land is proposed to be dedicated to Council to own and manage for public uses, this will include an all-weather sports field. 


Protecting the forest

There are important ecological elements to the site, including the Blue Gum High Forest and the Sydney Turpentine Ironbark Forest.

Currently the whole site is zoned as a business park with a height limit of 22 metres. Mirvac’s proposal seeks to amend the zoning to provide greater protection to forest areas and reduce heights across the site from 22 metres to 9 metres and 12 metres across the housing precinct, while retaining 22 metres for the apartment precinct only.

An E2 zoning for the remnant natural bushland, which offers the highest form of zoning protection, has been endorsed by both State and Local Government. This is a fantastic outcome for the site and community as it replaces the existing B7 Business Park zoning over the forest area providing a more appropriate land use control. 

In addition, we recognise and understand the importance the remnant forest has in relation to the protection of animal species, and detailed analysis and mapping has occurred by qualified and environmentally accredited consultants. This ensured all important areas were identified upfront, and fundamentally understood, acknowledged and respected in the design proposal

We have undertaken extensive work with multiple government agencies and have confirmed there are no koalas present on the site.


Community consideration

In relation to transport items, in addition to the detailed analysis undertaken with Council, thorough engagement has occurred with Roads and Maritime Services and they have raised no issues with the rezoning proposal.  Presently there are circa 1,700 car parking spaces on site with the proposal deleting approximately 720 car parking spaces, leaving circa 980. With the change from business to residential uses (residential being less intensive overall), and reduction in parking from existing high overall numbers on site,  independent transport analysis, studies and modelling has shown the proposal will generate significantly fewer trips on the local road network than the existing commercial use, even during peak periods.

Currently there is no legal public access through the site but under the proposal extensive parkland, open spaces and bushland areas will become publicly accessible to the community.

We anticipate about 1,200 residents living in the proposed master-planned community (less than the 3,500 odd workers that were using the existing facility at full capacity), and we are committed to ensuring 55 Coonara Ave fits in and contributes to the family-friendly West Pennant Hills community.


Transport options

The site is within an 800 metre walk to the new Cherrybrook metro station, due to open in the coming months and will be about three kilometres from the new Northconnex interchange.

The area is also well serviced by other public transport.


Update on assessment process 

Public Exhibition

The proposal was publicly exhibited by Council from 30th April 2019 to 31st May 2019.

In 2017 and 2018 Mirvac held public information feedback sessions and Council’s exhibition was another opportunity for the community to view the concept and proposals supporting material which has not changed from mid 2017 when it was first endorsed by Council. Publicly exhibited material included a Planning Agreement which outlines the public benefits prepared with Council that also form part of the proposal.

Any queries regarding the proposal can be directed to Mirvac at any time via our community information line 1800 531 535.

Council support

At a Council meeting in September 2018 the Hills Shire Council voted for a third time to support the proposal to transform the existing footprint of 55 Coonara Avenue into a family-friendly, residential community with public open space and an all-weather sports field.


We welcome the State Government and Council’s support for the E2 Environmental Conservation zoning, sought by Mirvac, as this provides the highest form of zoning protection for the remnant forest area.

In March 2018 Mirvac made an offer to the State Government to enter into an agreement to dedicate approximately 10 hectares of remnant forest area as regional open space. We are continuing to liaise with the State Government in relation to this item.

As part of the most recent Council endorsement, there were a number of updated ecological studies and reports that were considered during the assessment process.

Importantly, remnant forest areas are not proposed to be affected and greater protections will be put in place as part of the proposal.


We have been in discussions with Council about what public benefits are most needed in the area and, on advice of Council, the proposal is to create a full sized synthetic turf sports field with car parking that will be provided at no cost to Council and the community.

The use of the all-weather field will be determined by Council and we expect it will enhance the availability of sporting grounds in the area.

A draft Planning Agreement was also endorsed by Council in September 2018 for delivery of the sports field and dedication of 2.493 hectares of public open space and a public road.

Under the proposal, the extensive parkland, open spaces and bushland areas will become publicly accessible to the community.
