Knockdown rebuild builders: replace your existing house on the same block

A knockdown rebuild is a different job to a standard custom build on a vacant block. The builder has to coordinate demolition, deal with existing services (power, water, sewer connections already on site), and often work within tighter setbacks because the block is in an established suburb. Some builders run this as a package with a demolition contractor, others expect you to arrange demolition separately before they start.

Because you already own the land, the finance and approval path is different too. Councils sometimes ask for more detail on stormwater and retaining because the site has an existing house footprint and established boundaries. If you are looking to knock down an old house and build a custom design in its place, ask any builder you shortlist how many knockdown rebuilds they have completed versus greenfield builds, since the trades and sequencing are not identical.

• Demolition and asbestos checks on older homes
• Reconnecting or upgrading existing services
• Staying within existing block boundaries and setbacks
• the team accommodation planning while the build is underway
