Private building certifier in Kirribilli
Kirribilli is mostly apartments, but its Victorian and Federation terraces on steep harbour streets need careful certification. Levels and heritage controls set the agenda for most house projects.

Housing in numbers
At the 2021 Census, Kirribilli was home to 3,629 people in 2,597 private dwellings. Units accounted for 86.8% of occupied homes, terraces and semis for 6.8% and detached houses for 5.6%. Class 1 work is therefore a small but distinctive part of building activity. Because most residents live in strata buildings, the terraces and houses tend to be older, closely spaced and full of original fabric worth protecting.
Lie of the land
The North Sydney Local Environmental Plan 2013 sets zoning and height, and the North Sydney Development Control Plan 2013 guides design. From a ridge along Carabella Street, the ground drops to the harbour. Streets are narrow, some carriageways are split, and many lots are held up by retaining walls. One elevation of a building can look low from the street while another stands well above the ground.
Jeffreys Street terraces
The conservation area around Jeffreys Street keeps rows of terraces from the Victorian and Federation eras, built before the Harbour Bridge clearances. The DCP wants rear wings kept smaller with skillion roofs. Parking belongs beside or behind the house, never forward of the facade.
Typical work
Common projects and how they get approved
What owners build here
Realistic Class 1 and 10 projects in Kirribilli include:
- Rear terrace additions. Design around the kept terrace, its courtyard and the homes either side.
- Verandah and roof restoration. Match original details.
- Kitchen and bathroom upgrades. Confirm structure and shared walls first.
- Access and stair changes. Check levels against the street.
- Retaining wall repairs. Older walls on steep lots may need engineering before other work starts.
A full replacement house, large shed or wide front garage is rarely realistic in this dense setting. Apartment renovations and village shop work fall beyond Class 1 and 10. For those, use a certifier whose registration covers that class.
How approval usually works
Whether a CDC (a certifier's fast-track approval) is possible turns on heritage status and the precise scope. Inside the heritage area, most terrace additions need council's DA consent and then a construction certificate. Provide a measured survey, cross sections and drawings marking which walls, roof and verandah parts will be kept. In Jeffreys Street, judge a rear addition with the retained terrace, its courtyard and the neighbouring forms. Check first where the heritage area's edge runs and whether the house is listed in its own right. Construction access on narrow, steep streets also needs early planning. CertifiBuild can then recommend the right approval and carry out each inspection.

No two lots in Kirribilli are the same. Give us your address and we will check every map that affects it.
See the council pageWill council accept a front garage on a Kirribilli terrace?
Not inside the conservation area around Jeffreys Street. There, the North Sydney Development Control Plan 2013 wants cars kept beside the house or behind it, never in front of the facade. Outside that area other controls apply, but on Kirribilli’s narrow, steep streets a wide front garage is rarely realistic anyway. Check where the conservation area boundary runs and whether your terrace is individually listed before designing any parking, and plan around existing retaining walls and street levels.
How does the slope affect a terrace addition in Kirribilli?
Considerably. The ground falls from the ridge along Carabella Street toward the harbour, so an addition that reads as low from the street can stand well above the ground on its other side. Many lots also rely on old retaining walls, which may need engineering before other work starts. Draw the retained terrace with both street and rear levels in cross section before settling how tall the addition will be. Plan construction access early too, since narrow and split carriageways limit deliveries and equipment.
What drawings help with a Kirribilli terrace rear extension?
Start with a measured survey, then add existing and proposed cross sections and drawings marking exactly which walls, roof parts and verandah elements will be kept. Around Jeffreys Street, show the smaller rear wing with its skillion roof alongside the courtyard and the terraces on either side. Note any shared walls and structural changes too. Most terrace additions here need a development application (DA) and then a construction certificate, so a complete drawing set saves questions from council later.
