Central Coast Knock Down Rebuild

If you love where you live but your home no longer meets your needs, a knock down rebuild might be the perfect solution. It gives you the best of both worlds—a brand-new home built to suit your lifestyle, right on the block you already own.


At Blue Horizon Projects, based on the Central Coast, we help families start fresh without changing postcodes. Whether your current home is outdated, too small or just not functional anymore, we take care of everything from demolition and site prep to the final handover of your new home. The result? A modern, energy-efficient home that’s designed around you—with none of the compromises of a renovation.


If you’re ready to turn your current property into something brand new, call 0410 733 550 to book a chat and explore your options.

Rebuild Without Moving Away

A knock down rebuild isn’t just about upgrading your home—it’s about upgrading your whole lifestyle without sacrificing the neighbourhood you love.


We help you navigate the entire process with confidence, starting with site assessment, custom design options and any required council approvals. From there, we coordinate the demolition, clear the site and begin construction on a home that’s truly future-proof.


We consider everything—block orientation, layout flow, modern materials and energy efficiency—so your new home is not only beautiful but also functional and low-maintenance for years to come. We also understand the emotional side of rebuilding, which is why we make communication a priority and keep the whole experience as smooth as possible.


Whether your old home is beyond repair or you're ready for a completely fresh start, a knock down rebuild gives you freedom to create a space that works now and into the future.

  • Is it cheaper to knock down and rebuild or renovate?

    In many cases, a knock down rebuild can be more cost-effective than a major renovation—especially if your current home has structural issues, poor layout or extensive wear and tear. Renovations can uncover hidden problems that lead to budget blowouts, while rebuilding allows you to start fresh with modern materials and energy-efficient designs. A detailed cost comparison from a builder or estimator can help you decide what makes the most sense for your property.

  • Can I live on site during a knock down rebuild?

    Unfortunately, no. Once demolition begins, the site is no longer safe or suitable for living. Most homeowners either rent temporarily, stay with family or friends or explore short-term accommodation during the build. It’s important to plan ahead for this period and factor relocation costs into your overall budget. Some builders offer timeline guarantees to help minimise this disruption and keep the project on track.

  • How long does the knock down rebuild process take?

    The full process typically takes between 10 and 18 months from start to finish. This includes time for planning, design, approvals, demolition and construction. Demolition itself usually takes a couple of weeks, while the new build phase can take 6 to 12 months depending on the complexity of the home and site conditions. Delays due to weather, material availability or changes to the scope can also affect the timeline.
