What North Shore jobs need

Rock at the surface, neighbours at the boundary, and a council watching the trees

Digging in Kirribilli the question isn't whether you'll hit rock, it's how far down. Hawkesbury sandstone sits at or near the surface, so a pool, a basement or a garage cut is rock work: sawn at the boundaries so the neighbour's ground stays put, broken out in the middle, carted as rock. The blocks are steep and tight, the trees are protected and the neighbours are close, so vibration, dilapidation reports and crane or through-house access are part of the job, not extras.

What's different about digging in Kirribilli

Kirribilli, in short

Kirribilli sits about 5 kilometres north of the city. You'll recognise it by Kirribilli House, Admiralty House, Sydney Harbour and Milsons Point nearby. It's ringed by Milsons Point, Neutral Bay and North Sydney. What's changing: knock-down rebuilds, pools and basement garages on the steep blocks, and apartments near the centres.

The houses, and what they need

Around Kirribilli, near Kirribilli House, you're mostly on federation and interwar homes with harbourside apartments, with heritage pockets. Near Kirribilli House, the terraces are dug through the house or over the back fence. Day to day around Milsons Point that's basement digs, pool digs and retaining walls.

The ground under Kirribilli

Out toward Kirribilli House, Kirribilli sits on Hawkesbury sandstone with rock close to the surface on steep harbour slopes. The rock under Admiralty House is close, so Kirribilli footings and pits are broken out and the spoil leaves the block as rock. Around Neutral Bay, the sandstone is sawn at the boundaries and carted out as rock.

The council, access, and getting to you

Around Kirribilli House, Kirribilli carries heritage and tree protection controls in North Sydney Council, dug to the approved plans. Into Kirribilli the crew comes off Broughton Street or Fitzroy Street; the fall has to be benched and retained.

Excavation in Kirribilli, answered

How much does excavation cost in Kirribilli?

It depends on the volume of material, the ground (hawkesbury sandstone with rock close to the surface on steep harbour slopes), access for the machine and how far spoil has to be carted. Every job gets a written quote after a site look, with the dig, cartage and cleanup spelled out, so you know what’s included before anything starts.

Do I need council approval before you dig in Kirribilli?

Usually, if the excavation is part of a build. Cut and fill beyond set limits, work near boundaries and anything on a lot with a flood, bushfire or heritage overlay needs approval as part of the DA or CDC. We work to the approved plans; check with your certifier before the dig is booked.

How long does an excavation job take in Kirribilli?

A trench, pool dig or single pad is a day or two; a knock-down site cut or a basement runs longer and depends on volume, ground and weather. Dates come with the quote, not after.

Is there rock in Kirribilli?

Almost certainly. Hawkesbury sandstone with rock close to the surface on steep harbour slopes. Sandstone is at or near the surface across the North Shore, so pools, basements and garage cuts are rock jobs from the start: sawn at the boundaries, broken in the middle, carted as rock. It’s in the quote from the first site look.

Will breaking rock damage my neighbour’s house in Kirribilli?

Vibration through sandstone is real and the North Shore blocks are close, which is why boundary edges are sawn rather than broken, hours are kept to council limits, and a dilapidation report on the neighbours is standard before work starts. Monitoring is set up where the engineer requires it.

There’s no way to get a machine into my Kirribilli backyard. Can you still dig a pool?

Yes. Mini machines are craned over the house or walked through it, and rock comes out the same way in bins or by conveyor. Slower than a side-gate job and priced for it, but it’s how most lower North Shore pools get dug.

Can you cut a garage or basement under my existing Kirribilli house?

Yes, and it’s a common harbour-slope job. The rock is sawn at the house footing line and the boundaries and broken out in stages to the engineer’s underpinning and shoring sequence, so the house above stays where it is.

My Kirribilli street is a heritage conservation area. Can you still excavate?

Yes, to the conditions. Most older North Shore streets are conservation areas where work near a listed house or a protected tree comes with conditions on the approval, and vibration near old masonry is watched closely. We dig to what’s approved.
