Knockdown rebuild in Cremorne needs an honest framing, because the suburb is mostly apartments and townhouses from the 1960s to 2000s, with only pockets of Federation and inter-war detached homes on the side streets. So whether a knockdown even applies comes down to whether you hold one of those detached homes.
Where you do own a detached house on a side street, a rebuild can work well — these are premium blocks with water glimpses and a genuine lower North Shore lifestyle. Where you own an apartment or townhouse, a knockdown does not apply, and the conversation is a renovation instead.
The ground is Class M on the sandstone ridges, grading Class H to E on the harbour fall, so any build is designed off a real geotech. The older detached stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.
We build fixed-price, licence HBL 487805C. Tell me what you own and I will point you at the right product.

Depends what you own
Cremorne occupies the ridge between Mosman Bay and Shell Cove with the Military Road spine, and it is mostly apartments and townhouses from the 1960s to 2000s. Only pockets of Federation and inter-war detached homes sit on the side streets, so whether a knockdown applies comes down to whether you hold one of those.
On a detached side-street home, a rebuild can work well — premium blocks with water glimpses and a lower North Shore lifestyle. On an apartment or townhouse, a renovation is the conversation instead.
Harbour-fall soil and old stock
The ground is Class M on the sandstone ridges, grading Class H to E on the harbour fall, so any build is designed off a real geotech. On the sloping blocks, that can mean stepped footings and retaining.
The older detached stock can carry asbestos and lead paint, so a licensed strip-out leads any demolition.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. KDR feasibility is two questions: what can the block legally support, and is it cheaper to build new than fix old. We answer both in writing within a week, with cost ranges grounded in current Cremorne market data — not generic Sydney averages. New home designed for your Cremorne block — maximising FSR, orientation, and streetscape. Working drawings, engineering, and BASIX prepared. CDC or DA lodged with North Sydney Council.
⏱The Cremorne construction phase. Fixed price, programmed, supervised. Full demolition management: asbestos survey report, licensed removal where required, structural demolition, site clearing, temporary fencing, and dust/noise management. North Sydney Council demolition permit obtained beforehand. Build sequence: site prep, slab pour, frame stand, roof, brickwork, lock-up, plumbing and electrical rough-in, plaster, internal fit-out, kitchen install, tiling, flooring, painting, external works, final clean. Each stage signed off before payment release.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Defect-free handover inspection, OC issued, keys in hand. Permanent services reconnected, landscaping complete, 6-year structural warranty, and full maintenance guide provided.
