Clifton Gardens homes above Chowder Bay
Part of Mosman
Clifton Gardens is a harbourside locality within the suburb of Mosman, postcode 2088, and Mosman Council assesses its development. Clifton Gardens beach and reserve sit on the water beside Chowder Bay. Chowder Bay itself sits on headland land managed by Sydney Harbour Federation Trust. Council prepared a management framework and masterplan for Clifton Gardens Reserve in 2002, which looks at the history of the old hotel, baths and pavilion.
A named townscape area
Mosman's residential DCP includes a Clifton Gardens Townscape among its Part 7 character areas. Townscape areas are not heritage conservation areas, but they carry their own character and view controls. Check the townscape chapter alongside the general house controls before you design.
Views and slopes
Homes here step down towards the harbour. Council's DCP says new work must not significantly block views from neighbours' living and entertainment areas. Water and landmark views count for more than district outlooks, and where an iconic view is involved council can request height poles.
Typical work
Common projects and how they get approved
What owners build here
Clifton Gardens is mostly established houses on sloping land above the water, so work tends to be careful upgrades rather than quick additions. Typical jobs we certify include:
- Upper level additions, tested early for view loss from neighbouring living rooms and balconies.
- Rear extensions and rebuilds where the rear setback may be fixed by a foreshore building line.
- Pools and terraces cut into the slope, kept within council's excavation rules.
- Garages and carports, usually required to sit back from the front building line.
- Fencing and retaining walls along steep frontages and driveways.
How approval usually works
A CDC (a fast-track approval under state rules) may suit some Clifton Gardens jobs, but many hillside additions end up as a DA because of views, townscape or foreshore issues. Ahead of lodging, get a planning certificate to learn whether a heritage listing or foreshore building line touches the lot. Map the neighbours' main living areas and their outlook before fixing roof heights. The council DCP generally prohibits digging within the minimum setbacks, other than shallow service trenches, and expects ancillary excavation such as pools to stay 2 metres or more off boundaries. Front fences normally top out at 1.2 metres, while side and rear fences behind the setback can usually reach 1.8 metres. CertifiBuild reviews townscape, view and foreshore constraints for your lot before plans are finalised and replies promptly throughout the job.

Local questions
Questions we hear about this suburb.
No two lots in Clifton Gardens are the same. Give us your address and we will check every map that affects it.
See the council pageIs Clifton Gardens a separate suburb from Mosman?
No. Clifton Gardens is a harbourside locality inside the suburb of Mosman, postcode 2088, and Mosman Council assesses building work there. Council applies its local environmental plan (LEP) and residential development control plan (DCP) to private house lots. That plan includes a Clifton Gardens Townscape character area which has its own controls on character and views, separate from heritage conservation areas. The Chowder Bay headland is federal trust land, but private homes follow council rules. Start by ordering a planning certificate for the address.
Will my second storey block a neighbour’s harbour view?
It might, and Mosman Council will look closely. Its residential rules say new work must not significantly block views from neighbours’ living and entertainment areas. Water and landmark views carry more weight than general district outlooks, and where an iconic view is at stake council can ask for height poles. On the stepped slopes of Clifton Gardens, map your neighbours’ main living rooms and balconies before settling roof heights. Talking to neighbours early also helps. Many hillside additions here end up as a development application (DA).
How near the boundary may pool excavation go?
Under Mosman’s residential development control plan (DCP), digging for pools and similar structures should generally keep a gap of 2 metres or more to the boundary. Inside the minimum setbacks, excavation is usually limited to shallow service trenches. On the harbour slopes of Clifton Gardens, pools and terraces are often cut into the hill, so these rules shape where they can go. On some lots a foreshore building line also sets the rear limit. Check your planning certificate, then plot the dig and the barrier on a survey.
