Knockdown Rebuild Sunshine Coast Guide: Pros, Cons & What to Know
If you’re looking to build a new home on the Sunshine Coast, you’ve probably realised one thing pretty quickly—finding vacant land isn’t easy. Between limited land supply, ballot systems in new estates, and smaller block sizes, more people are turning to knockdown rebuilds as a smarter long-term investment.
While building in a new estate might seem like the easier or cheaper option upfront, it’s not always the best move when it comes to lifestyle, land size, flexibility, or return on investment. Here’s what to consider when deciding between a knockdown rebuild and buying a block in a new release area.
- Land Availability: Knockdown Rebuilds Open More Doors
Vacant blocks on the Sunshine Coast are in short supply. Most new estates operate through ballot systems, and even if you’re successful, you’re often waiting months for land to title—before you can even start building.
Knockdown rebuilds offer an alternative path. Properties with older homes on them are regularly coming to market in well-established suburbs like Buderim, Buddina and Golden Beach. Buyers are increasingly purchasing these for the location and land, not the house—and choosing to knock down and build something modern, efficient, and tailored to their lifestyle.
- Bigger Blocks, Better Locations
New estate lots are typically compact—often between 300–500m²—with narrow frontages and tight setbacks. By comparison, knockdown rebuild sites usually offer:
- More land for the home you actually want
- Established infrastructure and proximity to schools, beaches, and shops
- Street appeal and privacy in mature suburbs with larger setbacks and trees
You’re not just building a house—you’re building a lifestyle in a location that’s already proven.
- Multi-Generational Living & Rental Flexibility
One of the biggest advantages of a knockdown rebuild is the freedom to design a home that suits your stage of life—or several generations at once. With land sizes in older suburbs generally more generous, it’s much easier to include:
- A self-contained wing for grandparents or adult children
- A granny flat that can be rented out to help offset the mortgage
- Dual living layouts that support blended families or long-term guests
In a new estate, this sort of flexibility is often limited by space, setbacks, and developer covenants. With a knockdown rebuild, you can design your home to suit your real needs—not someone else’s master plan.
- Return on Investment: Long-Term Gains Outweigh Short-Term Savings
Buying in a new estate may look cheaper upfront—but cheaper land often comes with smaller blocks, less growth potential, and heavy design restrictions.
In high-demand areas like Buderim and Buddina, where the median house prices are now around $1.15M and $1.6M respectively, a knockdown rebuild on a larger block can deliver much stronger resale and rental value. Plus, dual living or a rentable granny flat can turn your new home into an income-generating asset from day one.
- More Design Freedom
New estates often come with strict design guidelines that limit your façade options, colour palettes, or materials. On a knockdown rebuild, you’re free to design a home that fits your vision, style, and budget.
You can:
- Maximise natural light and views
- Customise the layout for entertaining or privacy
- Future-proof your home with wider hallways, extra storage, or step-free access
It’s your land—your rules.
- Timeframes: Know What to Expect
While a knockdown rebuild does involve demolition and council approvals, it can sometimes be quicker than waiting for titled land in a new estate—especially when delays and infrastructure works push back start dates.
With the right builder guiding you through each stage, the process can be smooth, predictable, and personalised from start to finish.
So, What’s the Better Choice?

Frequently Asked Questions
Is it cheaper to build in a new estate than to do a knockdown rebuild?
Upfront, yes—vacant land in a new estate usually comes at a lower initial cost. But knockdown rebuilds often offer better long-term value thanks to larger block sizes, stronger location appeal, and greater design flexibility.
Can I include a granny flat or dual living in a knockdown rebuild?
Yes, absolutely—if your zoning allows it. One of the biggest advantages of a knockdown rebuild is the block size and layout flexibility, which often makes it possible to include a self-contained granny flat, multi-gen wing, or dual occupancy layout.
Are knockdown rebuilds allowed in every Sunshine Coast suburb?
Most suburbs allow knockdown rebuilds, but zoning, overlays, and setbacks vary between areas. We regularly build in Buderim, Buddina, Golden Beach and other established suburbs, and we’ll walk you through what’s possible on your specific block.
How much does demolition cost for a knockdown rebuild?
Demolition costs vary depending on the size of the home, access, materials (e.g. asbestos), and services. On the Sunshine Coast, most standard home demolitions range from $20,000 to $30,000, including approvals and disconnections. We’ll give you a clear estimate upfront and manage the entire process for you.
Can I build sooner with a knockdown rebuild or in a new estate?
It depends. While a knockdown rebuild involves demolition and approvals, new estates often face delays—especially if land isn’t titled yet. If your block is ready to go, a knockdown rebuild can sometimes start sooner.
Is multi-generational living popular on the Sunshine Coast?
Yes—and it’s growing. More families are looking to design homes with room for grandparents, adult children, or long-term guests. A knockdown rebuild makes it easier to design with this in mind, offering more space and freedom than what’s possible on a small estate block.
