Knockdown rebuild vs. major renovation: which one wins?

When the home you love is in the wrong shape, which path actually delivers the better long-term result? An honest comparison.

Knockdown rebuild vs. major renovation: which one wins?

Most of our knockdown rebuild clients started the conversation thinking they’d renovate. The right answer depends on your block, your home’s bones, and how long you plan to stay.

Quick comparison

Knockdown RebuildMajor Renovation
SuitsTired, post-war or poorly-oriented homesSolid existing structure, heritage or character
Cost certaintyHigher — one contract, one builderLower — discovery risk in existing structure
Timeline12 – 16 months end-to-end5 – 12 months depending on scope
Live-inNo — temporary accommodationOften yes, with planning

Signs a knockdown rebuild is the better path

  • The existing footprint can’t give you what you need.
  • Significant structural, termite or stumping issues.
  • You plan to stay 10+ years.
  • The home has genuine heritage character worth keeping.
  • The block is too tight for site works without demolishing more than you’d like.
We rebuilt on the same lot. Our daughter still walks to the same school — only now she has her own room.

Questions, answered

Is demolition included in your rebuild price?+

Yes. Our rebuild contracts include demolition project management, asbestos handling where required, and service disconnection.

Can we keep the existing slab?+

Sometimes — it depends on age, condition and whether the new footprint works above it. We assess this early.
