I significantly object this proposal. I do not support this proposal in its current form because it represents an excessive intensification of the site through increased building height, reduced minimum non-residential floor space, and therefore increased residents and housing.
My concerns are as follows:

1. Excessive Building Height

The proposal seeks to increase the height of the development beyond the established planning controls. This will create an overbearing built form that is inconsistent with the surrounding urban character and will contribute to an increasingly congested skyline within the Chatswood CBD.

The additional height will also increase overshadowing, reduce sky views, and diminish the visual amenity enjoyed by nearby residents and public spaces.

2. Significant Increase in Residential Density

The reduction in the minimum non-residential floor space allows substantially more residential apartments to be accommodated on the site. While this may increase housing numbers, it also significantly increases the resident population without a corresponding increase in supporting infrastructure.

The cumulative impact of multiple high-density developments occurring around Pacific Highway must be properly considered rather than assessing this proposal in isolation. Recent proposals along the Pacific Highway corridor are already contributing to substantial increases in population density within Chatswood.

3. Increased Pressure on Local Infrastructure

The proposal will place additional demand on already constrained infrastructure, including:

* Road congestion along Pacific Highway and surrounding streets.
* Public transport capacity during peak periods.
* Footpaths, public open space and community facilities.
* Local schools, childcare services and health services.
* Water, drainage and utility infrastructure.

There is insufficient evidence that existing infrastructure can accommodate the substantial increase in residents proposed.

4. Traffic and Pedestrian Safety

Additional residents will inevitably generate more vehicle movements, service vehicles, rideshare activity and pedestrian traffic.

Given the already congested nature of Pacific Highway and nearby intersections, the proposal is likely to worsen traffic delays and create additional safety risks for pedestrians and cyclists.

5. Cumulative Impacts

The Department should carefully consider the cumulative impact of this proposal together with the numerous approved and proposed developments throughout Chatswood.

While each individual proposal may appear acceptable when assessed independently, collectively they are transforming the scale, density and character of the area far beyond what existing infrastructure was designed to support.

For the reasons outlined above, I respectfully request that the Department refuse the proposed amendments in their current form or require significant modifications to:

* reduce the overall building height;
* retain the originally intended non-residential floor space;
* reduce the number of residential dwellings;
* ensure supporting infrastructure is demonstrated to be adequate before any increase in density is approved; and
* fully assess the cumulative impacts of this and other major developments within Chatswood.

The two unit blocks are already going to be taller than most in Chatswood, the addition of further floors and therefore people would put additional pressure on existing infrastructure including roads and transport. The metro is full to the brim now during peak hour when arriving in Chatswood. The roads into carparks already do not cope with existing volumes. Also as the site is on the hill, it will also overshadow existing properties. The height increase of more than double the existing plan will affect everything in Chatswood and allow further developments to take the same approach. While I am all in favor of additional residences, unit buildings with this height is not something we should be considering in Chatswood. Where is the green space, how will the schools cope, let them put money into improvements that will benefit existing residents or the residents that will purchase the units and how they will live in Chatswood.

This project will provide much needed high-quality housing in an area that has excellent public transport and public amenity. The development fits into the perfect niche of providing housing in a well sought after area that is connected to the public transport system, schools, shopping and public and private amenity and has little to no negative impact on the area in terms of overshadowing and traffic congestion.

OBJECTION TO SSD-93776214: CHATSWOOD GRAND RESIDENCES

CRITICAL PLANNING CONTROL BREACHES

This proposal seeks unprecedented planning control breaches: height increase from 90m to 209.5m (233% increase); FSR increase from 6:1 to 17.8:1 (297% increase); and reduction of non-residential space from 17% to 3.3% (80.6% reduction). These breaches are unjustified and should be refused.

APPLICANT'S OWN EIS ADMITS WIND IMPACTS

The applicant's Wind Tunnel Study (SLR Consulting, March 2026) explicitly acknowledges "Unfavourable Moderate" wind impacts at two pedestrian locations (14 & 16) in the through-site link. Table 5 (p.29) shows:
- Location 14: Target comfort C3 (Standing), Predicted C1 (Business Walking) = Unfavourable Moderate
- Location 16: Target comfort C3 (Standing), Predicted C1 (Business Walking) = Unfavourable Moderate

The study states: "All Unfavourable impacts are considered significant, requiring consideration of mitigation" (Section 4.2). The applicant admits proposed mitigation measures "were not included in the wind tunnel model due to scale limitations" (Section 8.1, p.33). The study recommends "3D CFD simulations may be undertaken" at Detailed Design stage—the word "may" indicates mitigation is uncertain, not assured.

The study further acknowledges that landscaping mitigation is unreliable: trees in high-wind areas experience "wind speeds every 5 years sufficient to destroy or severely damage many trees" and "landscaping planted in high wind locations rarely matures to its normal full height" (Section 4.3, p.13-14). Approval cannot be granted on unproven, speculative mitigation.

INADEQUATE PARKING CREATES SPILLOVER

The Transport Impact Assessment (JMT Consulting, April 2026) proposes 511 parking spaces for 552 apartments = 0.93 spaces per apartment. Standard provision in NSW residential developments is 1.2-1.5 spaces per apartment. This creates a shortfall of 100-250 spaces, forcing residents to seek parking on surrounding streets already experiencing congestion.

OVERSHADOWING OF NEIGHBOURING PROPERTIES

Twin towers of 56-60 storeys rising 200+ metres will cast extensive shadows across Day Street and Anderson Street residential buildings. Neighbouring residents will experience permanent loss of natural lighting, reduced solar access to living spaces, and diminished outdoor amenity. These impacts are irreversible and will devalue neighbouring properties.

INFRASTRUCTURE STRAIN

552 apartments impose massive burdens on local schools, childcare, water/sewerage, emergency services, and roads already at or exceeding capacity. The proposed $80M contribution cannot adequately address cumulative impacts. The 80-place on-site childcare centre addresses only a fraction of demand from 552 apartments (estimated 165-275 child places needed). Schools in the Chatswood area are at capacity.

TRAFFIC ON ALREADY-CONGESTED ROADS

The Transport Assessment acknowledges the site is in "an area experiencing congestion during peak periods" with Pacific Highway being "a major route" (Section 2.3, p.6). 552 apartments will generate hundreds of additional vehicle trips daily on already-strained roads. No adequate traffic mitigation is proposed.

RECOMMENDATION

The Department should REFUSE this application. If considered further, require: maximum height 120m (consistent with local context); FSR limited to 9:1; 1.3 parking spaces per apartment; 20% affordable housing; and independent verification of all wind, traffic, and visual impact assessments. Chatswood should grow within planning controls that protect community amenity, not be sacrificed for overdevelopment.

I support the project because it is ideally located in the Chatswood CBD, close to employment, shops and essential services, with excellent access to both the Sydney Metro and heavy rail network. The proposal will also deliver much-needed affordable housing and childcare facilities, create a more active and attractive retail frontage along the Pacific Highway, and improve pedestrian access and connectivity through the site. Overall, I believe the project will make a positive contribution to Chatswood and the wider community.

Chatswood Grand Residences is a good opportunity for well located market and affordable housing on a construction ready site.

To be honest, I want to see my city getting more international spill and aura. We need more high rises like this that have essential and premium shopping and eateries downstairs while creating convenient homes for families. The project should go ahead to solve so much needed social housing and Chatswood is a great area for it - see how many good education spots there for families with kids. If we want Sydney to grow and get developed for current and future generations we should not stop such submissions. Billbergia has a greta track record based on we can see in media and credentials like iCIRT and builders communities so they are the right company to make this project happen.

Dear Assessment Team,

I am a local resident living in the Chatswood area, and I would like to express my support for the proposed Chatswood Grand Residences Mixed Use Development.

Having lived in this area, I have seen Chatswood continue to grow into one of Sydney's most important commercial and residential centres. I believe this development is a positive step that will help meet the needs of our growing community.

The location is well suited for higher-density housing because it is close to public transport, shopping centres, schools and employment opportunities. Providing more homes in areas with existing infrastructure is a sensible and sustainable approach to future growth.

I also welcome the proposed mixed-use design, which will bring additional retail, public spaces and improvements to the streetscape. I believe these features will make the area more vibrant, convenient and enjoyable for both residents and visitors.
As a local resident, I appreciate developments that contribute to the long-term vitality of the community while making efficient use of land in well-connected locations. I believe this proposal will have a positive impact on the Chatswood precinct and will benefit both current and future residents.

For these reasons, I respectfully support this proposal and hope it will be approved.

Thank you for considering my submission.

Kind regards,

I would like to object to the project for the following reasons:
1. The additional height and infill will have an effect of increased shadowing and obstruction of morning sunshine for properties in Anglo Street, Chatswood and surrounding streets.
2. Increased population density in the area without increased road infrastructure. This project will bring many more residents cars to the area, contributing to an already congested traffic area.
The existing approved project is significant, and I feel that increasing the height, volume of traffic, and population density even further will stretch relations with the surrounding Chatswood residential community beyond an acceptable limit.

Re: Objection to Proposed Increase in Building Height from 90m to 209.5m for this project.

I am writing to formally object to the proposal to increase the approved building height for the above development from 90 metres to 209.5 metres.

The original approval granted in December 2025 was based on a comprehensive assessment of the development and its impacts on the surrounding area. The proposed increase to 209.5 metres is not a minor amendment but a substantial change that significantly exceeds the height previously considered acceptable.

My primary concern relates to the cumulative impact of recent high-density residential developments approved within our area. In recent years, numerous apartment projects have been approved and are either under construction or recently completed. While growth and development are important, the supporting infrastructure and community services do not appear to be keeping pace with the increasing population.

The road network is already experiencing significant congestion during peak periods. A development of this increased scale will generate additional vehicle movements, placing further pressure on local roads, intersections, parking availability, and public transport services. Residents are likely to experience longer travel times, increased traffic delays, and reduced road safety.

In addition, there are concerns regarding the capacity of essential community facilities, including schools, childcare centres, medical services, recreational facilities, and public open spaces. Before approving a development of this magnitude, a comprehensive assessment should be undertaken to demonstrate that adequate infrastructure and services are available to support the projected increase in residents.

The proposed increase in height may also result in adverse impacts on local amenity, including overshadowing, loss of privacy, increased wind effects, visual bulk, and a significant change to the character and skyline of the area. These impacts should be carefully assessed and publicly disclosed.

Furthermore, approving a height increase from 90 metres to 209.5 metres would establish a precedent for future developments seeking substantial departures from existing planning controls and previously approved limits. Such a decision could undermine community confidence in the planning process and the integrity of established planning frameworks.

For these reasons, I respectfully request that the application to increase the building height to 209.5 metres be refused. Alternatively, if the proposal is to be further considered, I request that an independent assessment be undertaken addressing the cumulative impacts on traffic, infrastructure capacity, community services, urban amenity, and local character before any decision is made.

Thank you for considering my submission.

Yours faithfully,

Judy
