Renovating Homes in Northbridge
A home renovation in Northbridge earns the harbour — 1920s to 1970s homes on 500 to 900m² blocks with substantial fall to Middle Harbour on the water-side streets, where the renovation's job is capturing the outlook the block already owns.
On the falling lots, suspended structures and retaining are engineered early. Near Sailors Bay Road, the Heritage Conservation Areas shape the frontages, checked before design.
The sandstone-dominant ground is read by geotech, and the older fabric gets the lead-paint and asbestos checks by era.

Capture what the block owns
Northbridge's premium is the harbour, and many 1920s-70s homes under-use it — the renovation reorients living toward the water, opens the plan, and adds the glazing and levels the fall makes possible.
On the falling lots, the engineering is designed and priced before the first sketch is sold.
Heritage streets, sandstone ground
The HCAs near Sailors Bay Road shape the frontages — checked before design. The sandstone ground is read by geotech, and the era-appropriate lead-paint and asbestos checks are licensed processes.
All priced into the scope upfront.

How It Works
From First Call to Final Key
A Northbridge renovation starts with what's worth keeping. Character floorboards, structural brickwork, original joinery — if it earns its place, it stays. Everything else gets a hard look.
⏱Design is pragmatic. Removing the right wall to open a kitchen, upgrading the bathroom to function properly, fixing the laundry that was an afterthought in 1975. Structural engineer signs off before anything load-bearing moves.
⏱Construction runs in stages so you can live in the house for parts of it. Wet areas and kitchens get a clear programme — three weeks without a kitchen is normal; three months is someone else's job.
⏱Handover is clean. New work tied into old work with matched finishes, defects fixed before you move back into the finished zones, warranty on all new work.
