Knockdown Rebuild Builder in Jannali
A knockdown rebuild in Jannali is a quiet Shire play with a river edge — 1960s to 1990s fibro and brick on 550 to 800m² R2 blocks backing toward the Georges River foreshore at Como. The aging stock suits a modern rebuild, and the stepped blocks reward good design.
The sandstone bedrock brings deep substructure scope on the stepped blocks — rock of $30,000 to $120,000 priced from a geotech bore, with stepped footings on the fall. On the foreshore lots, the Foreshore Building Line and Crown Lands referral apply to river-frontage works.
The fibro-era stock usually carries asbestos, so a licensed strip-out and clearance certificate lead the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the rock, steps and foreshore checked, before you commit.

Quiet, with a river edge
Jannali's 550 to 800m² blocks back toward the Georges River foreshore at Como, and the stepped topography rewards a design that works with the fall rather than fighting it. The aging fibro and brick stock is well into rebuild territory.
It is a quiet, settled suburb with its own station and genuine value.
Stepped substructure and foreshore
The sandstone bedrock brings deep substructure scope on the stepped blocks — rock of $30,000 to $120,000 priced from a geotech bore, with stepped footings on the fall. On the foreshore lots, the Foreshore Building Line and Crown Lands referral apply.
The fibro-era stock usually carries asbestos, so a licensed strip-out and clearance certificate lead the demolition.

How It Works
From First Call to Final Key
KDR starts with an honest look at the existing house. Sometimes it's worth keeping. Most Jannali homes from the 1960s–1990s fibro/brick veneer predominant + 1990s–2010s brick (Menai/Bangor/Illawong/Alfords Point) + 2010s+ premium contemporary (Cronulla beachside/foreshore) — especially fibro and brick-veneer — are beyond the point where renovation makes sense. We tell you straight.
⏱Demolition is pre-approved to run parallel with rebuild design. Asbestos cleared, services abolished, site stripped in a single mobilisation. Geotech reconfirms Class Hawkesbury Sandstone bedrock soil with the old house gone.
⏱New house goes up on the same footprint or a better one, whichever serves the block. Modern NCC envelope, better orientation, fit-for-purpose room sizes. The suburb stays the same; the house finally fits it.
⏱Final handover: new OC, six-year structural warranty, all the documentation on your Jannali block you'd get on a greenfield build. The only difference is you still live in the street you chose.
