I object because of the large scale, the lack of blending in and the dominant size over the neighbouring properties in all directions. It will be an eyesore in what is a beautiful environment. I don’t believe in this ‘affordable housing’ stuff, because whoever is going to be there as ‘poor ‘ people, the rent or purchase price will not be affordable for people who really need it need it. Not to mention the lack of infrastructure. It is just an excuse for greedy developers & property owners to make a lot of money at the expense of the people who live here.

Objection: 40-48 Redan Street, Mosman

To: The General Manager / Planning Department, Mosman Council

Subject: Objection to Proposed Residential Development (In-fill Affordable Housing) – 40-48 Redan Street

I am writing to formally lodge my strongest objection to the proposed development at 40-48 Redan Street. As a fourth-generation resident with over 30 years of personal residency in Mosman, I have a profound interest in the long-term preservation of our local environment.

My objection is based on the following grounds:

1. Incompatibility with Local Character and Topography
The "slopes" of Mosman are defined by a specific topographical rhythm and low-to-medium density scale. This proposal introduces a level of bulk and scale that is fundamentally at odds with the established streetscape. By ignoring the natural contours and the existing architectural vernacular, the development threatens to permanently degrade the visual amenity of the area.

2. Dangerous Planning Precedent
The height and density of this proposal represent a significant departure from the Mosman Local Environmental Plan (LEP). Approving this development would set a precarious precedent, effectively "opening the door" to high-rise encroachment. We risk a transition toward the high-density profiles of Manly or the Gold Coast, which contradicts the strategic planning vision intended for Mosman’s unique residential zones.

3. Impact on Infrastructure and Amenity
A development of this magnitude, positioned on the narrow and often congested corridors of the slopes, raises serious concerns regarding:
-Traffic and Parking: Increased vehicle movements on Redan Street, which is already burdened by limited capacity.
-Privacy and Overshadowing: The verticality of the build will result in an unacceptable loss of privacy and solar access for neighboring properties.

4. Community Sentiment and Social Impact
There is an overwhelming consensus among long-term locals that this development is an over-reach. While the provision of affordable housing is a noted goal, it should not be used as a "Trojan horse" to bypass height restrictions or to bypass the fundamental principles of orderly and sustainable development.

Conclusion
This proposal represents an irreversible shift in the landscape of Mosman. I urge the rejection of the application in its current form and protect the heritage and character that generations of residents have worked to maintain.

Sincerely,

Cassandra Hargreaves

The size of the proposed development is outrageous and blocks the Easiern light and views of the 4 residences on the other side of Redan lane devaluing their houses financially and inhibiting their lifestyles enormously in regards to privacy and for all the ressons the owners bought there initially. Redan lane is very narrow and cannot support the cars travelling on it . The damage caused by excavation will impact properties in close proximity to the proposed site. It is money driven and completely invasive of Balmoral slopes.

This is a good development, in a good spot for more housing.

As a Mosman resident, Mosman has been underdeveloped for a long time, a key contributor to the housing crisis. It is good if this now gets addressed through sensible developments like this.

This development is just a short walk from lots of commerical real estate, and both Spit Junction and Mosman Junction which are transport hubs. 53 Aparents is a sensible amount.

I hope the department will make the right decision in line with the state government's overall housing goals

I am writing to lodge a formal objection to the proposed 10‑storey development on Redan Street. As a local resident deeply invested in the preservation, safety, and character of our neighbourhood, I have significant concerns regarding the scale, suitability, and impacts of this proposal. The development is inconsistent with Mosman’s planning principles, presents avoidable risks to the community, and does not respond sensitively to its surrounding context. There is deep concern and loss at stake for neighbours of this development and this sets an unacceptable precedent for development and the future of Mosman. It is a clear abuse of the intention of the LMR laws which are intended for "affordable" housing.
1. Excessive Height and Bulk
A 10‑storey tower is entirely out of scale with the established low‑rise character of Redan Street and the broader Mosman area. The surrounding streetscape is defined by one‑ and two‑storey dwellings, heritage homes, and modest residential forms. A building of this size will dominate the skyline, overshadow adjacent properties, and fundamentally alter the character of the neighbourhood.
2. Overdevelopment and Structural Risk
The proposal involves excavation up to 10 metres into sandstone, extending right to the site boundaries. This raises serious concerns about:

Ground movement
Vibration impacts
The structural integrity of neighbouring homes

Such intrusive excavation suggests that the site is being forced to accommodate a building far beyond what it can naturally support. The design should respond to the constraints of the site—not the other way around.
3. Heritage Impacts
The development directly adjoins heritage‑listed properties at 36 and 38 Redan Street. A 10‑storey structure would visually overwhelm these heritage items, eroding their setting and diminishing the historical character of the street. Protecting Mosman’s heritage means ensuring new developments complement—not overpower—existing heritage fabric.
4. Conflict with Scenic Protection Area Objectives
The site is located within a Scenic Protection Area, where the planning objectives focus on:

Minimising visual intrusion
Preserving landscape character

A building of this scale is irreconcilable with these objectives. Its height and mass would interrupt important view corridors and significantly impact the visual amenity of the surrounding neighbourhood.
5. Traffic and Access Concerns
The proposal relies on access from Redan Lane, a lane that:

Is only slightly wider than 4 metres
Has no footpaths
Is unsuitable for waste trucks and service vehicles

Introducing additional traffic—including larger service and emergency vehicles—into this narrow laneway creates clear safety hazards for residents and pedestrians.
6. Lack of Supporting Infrastructure
Mosman’s infrastructure is already under pressure. With:

A single fire station
Limited emergency services coverage
Narrow residential streets ill‑suited for large rescue vehicles

It is unclear how emergency response times or access would be maintained for a 10‑storey building. This raises legitimate concerns for both current and future residents.
7. Non‑Compliance and Misleading Claims
The development exceeds height controls and requires a Clause 4.6 variation, yet has been described as compliant. A proposal that breaches fundamental planning controls cannot credibly be considered compliant, and such claims risk misleading the community and undermining the intent of the planning framework.
8. Affordable Housing Design and “Poor Door” Concerns
While the inclusion of affordable housing is positive in principle, the proposed design raises serious equity and access issues:

Affordable housing units are segregated from the main building
Residents would access their homes via the constrained laneway
This creates an unfortunate “poor door” scenario that is neither inclusive nor consistent with contemporary expectations for integrated, respectful affordable housing design.


This proposal represents an inappropriate and excessive scale of development for Redan Street and Mosman more broadly. It poses structural risks, undermines heritage values, conflicts with Scenic Protection Area objectives, exacerbates infrastructure pressures, and fails to provide equitable housing outcomes.
For these reasons, I strongly urge you to reject the application in its current form.

To the NSW planning authority
Re - Residential Development with In-fill Affordable Housing - 40-48 Redan Street Mosman
20 March 2026
From, Mosman resident
I would like to submit my objection to this proposal. There are many factors that make this proposal untenable for our local community.
While construction work is always a short-term impact or years long impact depending on the build timeframe, given there are numerous projects in our local area the overreaching impact will be significant and impact quality of life minimum levels. It will increase mental stress issues and sense of safety. Builder never consider their impact on the community they work in. The current developer hungry profit focused approach to development which is not considering the impacts to community needs to stop. Proper town planning and full consideration needs to start. I am someone who has lived in this area for 20 years in a unit dwelling and I fit the profile as someone needing affordable housing solutions, however this is not the way and not solving any of the actual problems as I will not be able to live in any of the new dwellings, in fact it will only decrease my ability to live in this area where I wish to be close to my parents who are aging but also provide me support as a single mother. I ask for proper planning laws not careless ones.
Objections to the Redan street proposal
1. Traffic - Parking – Access: Redan Lane is only 5 meters wide and has no side walk or natures strip and has a dog leg in the middle. This development will adversely affect the pedestrian safety on Redan lane. The traffic, parking and access will significantly impact locals during the construction phase and beyond. Resident visitors use the lane for parking that will be adversely affected to. Adding in this number of residents in this location further puts strain on the infrastructure that can’t currently meet the needs of the community. Transport is already and issue, traffic is congested, especially at peak times. We are unable to catch buses as they are all full. The ferries are also congested. So many of the community drive to work for various reasons and our roads are not able to cater for this. This location while it might be near local shops and cafes and other lifestyle factors noted in the submission it is not the lived reality.
2. Privacy – Locals within the immediate area will lose their sense of safety which is provided by the current privacy of our community. The sheer height of the building, 10 levels of bedrooms will be able to view neighbouring properties living area and verandas. This is not a fair or reasonable or balanced community development approach to significantly impact private dwellings in this manner.
3. Impact to sustainable energy solutions - Shadowing will significantly impact the neighbouring properties and be problematic for those who have invested in sustainable energy solutions like solar panels.
4. Safe walking - Redan Lane is not a safe walking route from the town centre to this proposed development. Which is noted in the Pre-lodgement notes from the meeting notes 16 April 2025
5. Scenic Protection Line - Mosman LEP 2012 identifies the 60 meter contour as the Scenic Protection Line. All but one level of this proposed development are above the Scenic Protection Line.
6. Redan Lane size specific challenges – Redan Lane is a 5-meter-wide lane and can not accommodate the current traffic, garbage collections or parking needs. It is beyond ridicules to build a10 level buildings on either side of the lane, that would need to cater for parking, guest parking, visitor parking, overflow parking and traffic. It prevents significant risk factors for pedestrian safety, driver safety. There is no room for pedestrians to walk along the lane when there is a car struggling to negotiate the tight lane and tight bend. Garbage bins currently already cause significant challenges and risks on collection days, further adding to the difficulty of safe walking and driving. If environments are not safe it impacts people sense of safety which then creates psychological risk factors, stress, rage, mental fatigue.
7. Local architecture and community -
• This proposed development is in the middle of Redan Street ( a heritage street), No. 36-38 Redan Street (heritage house) and Redan Lane ( a narrow Lane not suitable for a development of this height).
• The current style and character of architecture and charm of the area will be significantly impacted, and the new development does not consider or try to blend in and positively impact the local area. There are better ways to ensure the new buildings that bring these ‘large volume of dwellings’ into areas be applied and had architectural harmony to the area. People want to live in lovely areas this is how we create great community cultures and safe spaces. While this may not be law, this is still a fact and should still be a consideration. This new building does nothing to beautify the area it only offers the opposite.
8. LMR boundaries not met - All councils in NSW require that LMR applicants provide a survey plan showing the exact safe walking measurement from town centres or train station entry gates to their proposed development. I couldn’t find such survey for this application. If you review the LMR 400m & 800m boundaries it clearly shows 40-48 Redan Street properties are outside the 400m line.
9. Height of building proposed - According to the LMR Policy the max height for proposals within 400m from the town centre is 4 level ( + 2 levels affordable units) and it is 6 level ( + 2 levels of affordable units) for properties located between 400m and 600m from the town centre. This proposed development is 10 levels high.
10. Other factors – Congestion in the areas beyond Parking and transport burden more buildings will have. The type of support needed for the new residents, will it be small families, if so then there is currently a shortage in daycare centres in the area and no feasible new ones. Will it be the older citizens, what services do we have to support them and how will they access Redan street, parking is already unavailable. This location simply can’t support the increased burden it will introduce and a more modest development would be far more suitable, while potentially less profitable for a developer. Developer profits should not be a reason to build big buildings in communities and locations it’s not suited to.

Again a totally unacceptable building for the area. No thought for those already residents who didn't buy here to have that ugly monstrosity built on the site. Roads and infrastructure not in place for that many units. We all know there will not be affordable units in this position but elsewhere. Once we lose what is wonderful about suburbs it cannot be regained . What people love about Sydney is not this thoughtless developer rush to make ugly high rise wherever possible. I am sure others can make more detailed assessments than I but still I object.

I object to the proposal on the basis of the excessive height and scale, the adverse impacts that the development will have on the heritage character and streetscape of the area , the negative impact it will have on traffic and the unfair burden it will impose on local infrastructure. In addition, this development is a perfect example of how the community is being deceived by the so-called "affordable housing" element: this is nothing but an excuse for developers to make massive profits, it is merely window dressing that will not proivide immediate or long term "affordable housing" and it will create an under-class of residents who have to use a spearate entrance and get the worst units in the development.

To The Secretary
NSW Department of Planning, Housing and Infrastructure,
