Please find attached the completed submission form and accompanying report regarding the proposed development at 40-48 Redan St, Mosman (SSD-93020230). This submission formally registers a strong objection to the proposal on behalf of the Strata of 77 and 2/77A Muston Street.

Please refer to our attached submission. Thank you for your consideration.

Traffic gridlock. This proposal would introduce at the minimum 103 more cars to the neighbourhood plus so many more service vehicles for 53units. Plus visitors trying to find a place to park on the street. This location simple cannot accept this increase in such a large number of cars. It is already gridlock at its intersection of Upper Almora and MilitaryRoad. Traffic is at a standstill on Military Road already. This is untenable.
Surrounded on all sides by beautiful, old and heritage listed grand homes this proposal for a 12 storey building with levels for cars is simple too big in size and scale. The surrounding homes would’ve dwarfed and adversely affected. Their beautiful views would be obliterated, the breeze from Balmoral blocked, sunlight would be blocked for hours and any semblance of privacy through our windows and into our gardens would be lost forever. Too many factors by building such a building make this proposal u tenable.
This proposal does not fit the brief. It is not going to provide suitable housing for low income workers as their entrances would not be safe. They would have to enter through a narrow service lane. They would not be afforded the dignity to enter the same way as other residents.
The developers have not been transparent with Mosman Council and have not provided them with the detailed studies necessary that prove that digging such a large hole and building such a huge structure would not impact the surrounding areas or damage nearby homes structurally. Any development on this site should not go ahead until the developers can prove to Council that their project would do no harm to the surrounding ground and nearby residences.

I believe that this development is entirely unsuitable to be built where it is proposed. Should a development of this scale happen it will set the precedent for a Surfers Paradise style approach for the cherished Balmoral Slopes.
The bulk, height and scale of the development is totally inappropriate in that location where there are currently a collection of beautiful Federation homes.
The negative impact on the surrounding residences is enormous in so many ways. The complete loss of amenities for some neighbours is a colossal change in their circumstances.
The size of the development will cause traffic and parking congestion.
The concept of Affordable Housing is being abused here to not actually be affordable but instead allow even further height for the developers.
A development with no merit in this position.

Submission on 40–48 Redan Street SSD Proposal
From: Geoffrey Lang, 28 Mandolong Rd, Mosman

I am writing to strongly object to the proposed 10-storey development at 40–48 Redan Street. As a close neighbour with a young family, I am deeply concerned about how this project would harm our daily life, our community, and the natural environment that surrounds us.

The scale of this building is completely out of place. A 10-storey tower on a low-rise street would dominate Redan Street, overshadow heritage homes at 36 and 38 Redan Street, and irreversibly alter the calm, neighbourly character that makes this area so special. The apartments are clearly high-end and unaffordable, offering little for local families or inclusive housing.

The site borders the Balmoral slopes environmental living area, a place rich with native flora and fauna that my family and I regularly enjoy. This development would destroy part of that natural setting, disrupting wildlife habitats, reducing green space, and eroding the sense of connection to nature that defines this neighbourhood. For families like mine, the slopes are a critical part of outdoor life, recreation, and wellbeing. Losing this access to nature would be a significant, irreversible impact.

Excavation of up to 10 metres into sandstone so close to other homes adds further risk of structural damage, vibration, and ground instability. Living nearby, this creates daily stress and anxiety for my family.

Traffic and safety are also major concerns. Redan Lane is narrow, lacks footpaths, and is not built to accommodate the increase in vehicles from construction, services, or future residents. This would make everyday life more hazardous, particularly for young children.

Combined with reduced sunlight, blocked views, and the limited consultation process, this proposal prioritises developer profit over people, community, heritage, and the natural environment. It is excessive, intrusive, and wholly incompatible with the neighbourhood. I strongly urge the authorities to reject it.

I wish to register my objection to the proposed development on the following grounds:
1. The building has such excessive height and bulk that it is offensive, with a 10-storey building that is clearly out of scale with the surrounding low-rise streetscape and will dominate the surrounding area. This is contrary to the overall planning objectives to maintain the scale and character of adjoining properties.
2. The proposed building fails to respect the established character of Mosman and constitutes architectural vandalism.
3. The building conflicts markedly with objectives of the Scenic Protection Zone, which applies from the waterline to the 60 metre contour and is intended to protect significant views to and from Sydney and Middle Harbours. A 10-storey building is difficult to reconcile with these objectives as it destroys the carefully maintained streetscape.
4. There will be significant overshadowing of the living areas of neighbouring homes as a result of this development.
5. The proposal is not justified by public benefit and there is no strategic need to have this building in this location and the properties for sale are unlikely to be affordable for the people for whom the policy is most clearly meant to be targeted. The motivation for "infill housing" is purely greed driven at the expense of the local community, rather than a genuine desire to create real affordable housing long term.
6. The development sets an undesirable precedent for overdevelopment in Mosman.

I do not support the Development (SSD) proposal for 4-048 Redan Street Mosman.

I have attached a letter outlining my objection to this massive, monolithic, un-Australian (with poor doors), completely unsuitable development in a suburb that was created early in the settlement of this colony and contains many heritage houses.
