I am writing to formally object to the proposed State Significant Development at 100 Edinburgh Road, Castlecrag. I grew up in Northbridge and remain closely connected to this community. My mother continues to live in the area, and I have a genuine and longstanding interest in its character, liveability, and future.
My objection is not reflexive resistance to development. It is a considered response to a proposal that is fundamentally out of scale, out of character, and out of step with the planning framework that governs this area.
1. Heritage and the Griffin Legacy
Castlecrag is not an ordinary suburban precinct. It was designed by Walter Burley Griffin and Marion Mahony Griffin as a deliberate integration of built form and natural landscape – one of the most significant examples of planned heritage environments in Australia. The Griffin vision is explicit: buildings should sit within the landscape, not dominate it.
This proposal does the opposite. An 11-plus storey tower at the gateway to the conservation area is not a sensitive response to heritage – it is a direct contradiction of it. The EIS minimises heritage impacts rather than genuinely assessing them, and the Design Review Panel has itself identified unresolved issues with bulk, massing, and heritage response. That the application has proceeded in this form is deeply concerning.
2. Incompatibility with Local Character and Built Form
The site sits adjacent to low-rise residential dwellings. There is no graduated transition in scale proposed – just an abrupt interface between the surrounding neighbourhood and a high-rise structure with no precedent in the locality. The proposal exceeds height limits that apply even in Northbridge Town Centre, which has a higher planning classification than Castlecrag. This is not a minor departure from character – it is a wholesale departure from it.
3. Planning Non-Compliance and Flawed Justification
The application relies on planning logic that simply does not apply here. Castlecrag is not an LMR-designated growth area, and the EIS incorrectly imports density uplift rationale from Northbridge, which is a designated growth centre. The site has no rail or metro access – it is 3 to 4 kilometres from the nearest station – meaning Transit Oriented Development principles cannot be legitimately invoked. Compliance metrics appear to have been manipulated, with retail and public space combined and rounded up to meet thresholds. This is not a borderline case requiring nuanced judgement; it is a proposal that does not meet the basic tests of its own planning framework.
4. Traffic and Infrastructure – A Network That Cannot Cope
The road network in and around Castlecrag is already operating beyond comfortable capacity. This proposal nearly doubles parking provision from 163 to 376 spaces, yet simultaneously claims reduced traffic impact – a conclusion that defies logic and directly contradicts prior modelling. No meaningful network mitigation is proposed.
But the deeper problem is public transport. The site is 3 to 4 kilometres from the nearest rail station. Bus services are infrequent and largely impractical outside weekday peaks. The EIS attempts to characterise the site as well-served by public transport – a claim so disconnected from reality that the project’s own construction planning documentation contradicts it, acknowledging poor transport access in that context while the planning justification claims the opposite. That internal contradiction alone should raise serious questions about the integrity of the assessment.
Transit Oriented Development principles exist precisely to ensure density is located where people can actually live without a car. This site fails that test entirely. Approving high-density residential development here does not reduce car dependence – it guarantees it, and pushes the consequences onto local streets not designed to absorb them. The likely result is increased rat-running through residential streets, and genuine pedestrian safety risks near local shops, schools, and crossings.
The infrastructure case for this development does not exist. It has been asserted, not demonstrated.
5. Community Impact and Loss of Village Character
Beyond the technical non-compliances, this proposal removes community facilities that were previously part of the design, replaces genuine public space with retail circulation, and offers affordable housing at a level (6.67%) that will deliver no real benefit to low or middle income households given local market rents. The community consultation process was inadequate, and by the developer’s own admission, no modifications were made in response to community feedback. This is not a development that gives anything meaningful back to the community it will permanently alter.
Conclusion
I am particularly concerned that this application is being advanced during a period of expanded State Significant Development pathways. That mechanism exists to facilitate projects of genuine state-wide benefit – not to override legitimate local planning frameworks in heritage-sensitive areas with inadequate infrastructure. Approving this proposal would set a precedent that undermines the integrity of planning controls across similar communities across NSW.
I urge the Department to refuse this application in its current form.

I support the proposed residential and retail development in Castlecrag as I believe it will be a positive change for the suburb and help improve activity within the local village area.
The project will provide more housing options for people at different stages of life, including older residents looking to downsize while remaining in the area. It will also help encourage further growth and investment within the suburb, supporting future retail, service, and logistics-related businesses over time.
Overall, I believe the development is a good opportunity to modernise the area and support the long-term growth of the community.

The proposed development is overwhelming, and it completely destroys the skyline the suburb is famous for. The residents and visitors to Castlecrag have appreciated its ambience and charm with its tree lined skyline especially at sunset. As a result of this project the traffic will increase to an unmanageable level and will lead to angst and division in our community.
I am also concerned about the change on flow of land and sea breeze this project may cause and the fact there seem to be no assessment conducted on this.

Who takes responsibility for a developer who makes a wrong decision?

In the old days developers made a considered decision before spending their money. They consider: Is it capable of supporting the increase in population? Can public transport take the extra people? Can the sewer lines support the extra water flow? Are the roads wide enough? Do the people around there willing to give up street parking? Are the population being added to the area insympetico with the existing population. The developer himself studies the area understands the demographics. He thinks all this through before speaking his intentions. He tries to spend his money wisely.

These days it is easy to throw a dart on the map of Sydney and make your millions selling hundreds of units to unsuspecting buyers. After all, every unwise decision can be fixed.

Look at Lindfield. That development is shorter than this proposal. It feels like it will look similar to this development. It is built for the train station next to it. Shopping is convenient, a few well visited cafes, useful shops but somehow it feels cold. It has little real community feel to it. Do strangers talk to each other? Does it feel Australian? Whatever the plan was, Harris Farm has limited it's customers to those who can street park. Compare it to Bridgepoint, Mosman. Is that what is being built in Castlecrag?

I am worried about this development.

I am worried I'll have to leave my house half an hour earlier to be on time for work.

I am worried the sewer lines will clog up the drains and our trees will go.

I am worried the look and feel of Castlecrag will disappear with old residents leaving. These old residents represent and teach a inner city culture of Australia. The culture of how to live with nature and be part of the city. When the new residents in units arrive they will have little in common with those in houses.

I am worried people will discover the isolated pockets for homelessness and introduce crime.

I am worried the value of our houses being diluted or reduced due to traffic exiting the suburb .

I am worried our rates will increase when Willoughby Council have to
- amend their LSPS strategy,
- increase and change public transport requirements,
- have increased nature pathway maintenance
- Increased parking issues and complaints

Shouldn't the developer pay for the forced amendments to the Willoughby strategy.

Shouldn't the developer pay to the transport authority for their forced changes to the demographics.

The developer could also contribute annually to the Griffin Society for the upkeep of the suburb.

I am worried we are adding people who don't know and may have no interest in Castlecrags cultural significance, diluting this precious commodity.

These decisions of how to make this development work are placed with the planners. I hope they work for the greater good of Australia.

I hope the planners at least, since the developer evidently did not, visit the suburb, find out why they didn't know about it before, why it's the precious gem in Sydney.

I am not Australian, have visited and lived in Castlecrag for 26 years. It's a treasure, a rarity. A place I respect and would miss terribly if it's culture is lost. A place Australia would lose.

Castlecrag is a unique, beautiful and peaceful garden suburb of recognised heritage significance, shaped by the vision of Walter Burley Griffin. Its character is defined by low-scale development, integration with bushland, and a strong sense of community. The proposed development is fundamentally inconsistent with these qualities and would result in a significant and irreversible change to the character of the area.
The proposal involves a substantial mixed-use development including approximately 150 dwellings and two 11-storey towers above a podium. This form and scale are clearly out of character with the surrounding predominantly low-density residential environment. The Willoughby Local Environmental Plan and Development Control Plan require new development to respond to and respect the established and desired character of an area. In this case, the proposal introduces an intensity and built form that is more consistent with a major centre rather than a small, locally focused village.

While the proposal includes a proportion of affordable housing, this appears secondary to the overall scale and intensity of the development. The design and bulk of the project suggest that the primary driver is maximising density on the site rather than delivering housing that is genuinely aligned with the needs and context of the local community.

The Transport Impact Assessment further raises concerns about the capacity of local infrastructure. The applicant’s own analysis confirms that key intersections, including Edinburgh Road and Eastern Valley Way, are already operating at Level of Service F during peak periods, indicating significant congestion and delay 1. The development would introduce an additional 311–403 vehicle trips during peak hours 1, placing further pressure on a network that is already constrained.
Castlecrag does not benefit from rail or metro access and is heavily reliant on bus services, which are limited in frequency and already under strain. The area is effectively a peninsula with restricted entry and exit points, and the transport network has recognised limitations. The Transport Impact Assessment itself acknowledges existing traffic constraints and the need for future improvements to public transport infrastructure. However, such improvements are uncertain and should not be relied upon to support a development of this scale.

In practical terms, residents already experience crowding and delays in accessing public transport, including queuing for buses. The scale of this proposal would exacerbate these issues and reduce the overall accessibility and amenity of the area. This will be worsened during construction. There is one road in and out of Castlecrag - cyclists are not the solution.

From an environmental perspective, the site’s proximity to bushland and the broader harbour catchment reinforces the need for development that is sensitive in scale and form. The proposal’s height and bulk would be visually prominent and at odds with the natural and landscaped setting that defines Castlecrag. 11 storeys is way too tall for the area - it is visually unappealing and against the ethos of Castlecrag. Take the development next door near the Rampart, it was quiet and considerate in terms of height and aesthetic. The proposed 11-storey height represents a fundamental departure from the intended built form of an E1 Local Centre and fails to provide an appropriate transition to the surrounding R2 and R3 zones, resulting in a development outcome that is inconsistent with both the objectives of the WLEP and the built form controls of the WDCP.

This proposal does not represent well-aligned or sustainable growth. Sustainable development should be proportionate, infrastructure-supported, and responsive to local character. In this instance, the scale of the development exceeds what the site and surrounding area can reasonably accommodate.

I have written about this inappropriate development many times and will not bore you with lots of details. This a is a square peg in a round hole. It will be a blight on the community and it is totally wrong to suggest this is a transport hub and low cost housing will be available. Further, the disruption will be monumental (during and after the development) with just one road in and out of Castlecrag. People will be injured and killed through impatience and the community will go after anyone that approved this development. It is scandalous that this matter has gone so far. I am missing something. Please do not allow developer greed. Regards. Greg

I object to the project for the following reasons: not in keeping with the Griffins design of Castlecrag whose planning for Castlecrag focused on harmony with the natural landscape, low-rise developments. The towers are visually intrusive, out of scale with the surrounding area and will stand out. Castlecrag already experiences significant traffic during peak hours and these towers will place further pressure on roads and intersections, worsening traffic.

I am a homeowner at Castlecrag and vehemently object to the project on 100 Edinburgh Road as proposed by Conquest. As the proposed buildings will be right next to the only exit of Castlecrag, the significant increase of the residents living in the new buildings will cause a terrible traffic jam right at the intersection, making it extremely difficult for the people who live and work in Castlecrag to come in and out of Castlecrag. This situation cannot be alleviated since there is no train or Metro in Castlecrag. Being able to travel freely in Castlecrag is an essential right of the residents of Castlecrag and is a daily necessity. Thus, the new buildings would infringe upon a fundamental right of the existing Castlecrag residents, and Conquest would profit from this project at the expense of the existing Castlecrag residents with no compensation.

From a community perspective, high-quality developments can enhance local amenity and contribute positively to neighbourhood character. Well-designed buildings often lead to improved streetscapes, increased property values, and a stronger sense of cohesion within the area. The level of detail and apparent design quality in this proposal suggests it will be a positive addition to the locality.

It is also worth noting that development of this nature supports the local economy through construction activity and ongoing investment in the area. Projects that are carefully planned and executed tend to encourage further responsible development and help maintain high standards across the suburb.

This proposal represents a thoughtful and well-considered addition to the Castlecrag area. Developments of this nature can play a meaningful role in supporting local economic activity. Investment in construction and design not only creates jobs but also contributes to the ongoing improvement of the built environment. High-quality projects tend to uplift neighbouring properties and encourage further responsible investment in the area.
