What a renovation
costs in Coburg
Coburg spans two eras in a way few suburbs do — Victorian and Edwardian close to Sydney Road, then substantial post-war and mid-century housing further out. Which side of that line your house sits on matters more to your budget than the postcode does.

What drives cost here
Two housing eras, one postcode
Pre-1920 stock near Sydney Road carries the full restumping and rewiring allowance. Post-war housing further out carries almost none. Same suburb, roughly $26,000 apart before anything else is decided.
Merri-bek heritage precincts
Overlays cluster around the older streets and the former civic areas rather than covering the suburb. Check your address specifically.
Generous post-war allotments
The mid-century parts of Coburg have some of the widest blocks in the inner north. Side access is common, and it is worth real money.
Former industrial pockets
As in Brunswick, some land carries a light industrial history. A soil report early is far cheaper than a discovery mid-excavation.
Typical Coburg projects

| Rear extension to a post-war home | Wider block, good access, minimal work to the existing house. | $235k – $315k |

Common questions
Why do Coburg renovation costs vary so widely?
Because the suburb spans two building eras. Pre-1920 housing near Sydney Road needs restumping, rewiring and re-plumbing — around $26,000 before anything else. Post-war housing further out generally needs none of it.
Does Coburg have heritage overlays?
In defined precincts rather than across the suburb, mostly around the older streets and former civic areas. A planning property report for your address will tell you definitively.
Is Coburg cheaper to renovate than Brunswick?
Usually, though the gap depends on your specific house. Coburg blocks are generally wider with better access, and a larger share of its housing is post-war, which reduces work to the existing structure.
What is not included in these ranges?
Landscaping and external works, appliances, furniture and window furnishings, council planning application fees, driveway reinstatement, and anything found once walls are opened. Design fees, engineering, building surveyor, permit levy and energy assessment are included.
