Love your street, your neighbours and your location, but not the house sitting on your block? A knockdown rebuild lets you keep the address and start again, with a brand-new custom home designed around how you actually live today.
Why choose a knockdown rebuild
Renovating an older home often means working around load-bearing walls, outdated wiring and a layout that was never designed for the way families live now. Weighing up knockdown rebuild vs renovation, a rebuild removes those constraints entirely. You get a home planned from a blank slate, on land you already know and love.
What affects the cost
Knockdown rebuild cost depends on a few things: the size and condition of the existing house, demolition and site access, your chosen design and inclusions, and any council requirements specific to your block. We handle demolition, approvals and construction ourselves, and agree your price upfront before work begins, so there are no costly surprises partway through.
The approvals you'll need
A knockdown and rebuild process starts with a Development Application or Complying Development Certificate, alongside a contour survey and borehole report to confirm your block is ready to build on. Our team prepares and lodges this documentation as part of our standard preconstruction process, so you’re not left chasing paperwork on your own.
What to expect on site
Once demolition and site setup are complete, your build follows the same process as any new BuildTec home, with the same trusted trades, joint site inspections at key stages, and a detailed warranty inspection three months after handover.
