DownloadA knock down rebuild can be an opportunity to get into the home you’ve always wanted. Here, we break down some potential costs and savings, and consider some of the pros and cons of this method relative to renovation.
Most Brisbane knockdown rebuilds fall between $500,000 and $1,000,000+, depending on factors such as block conditions, home size, design choices and inclusions. While every project is unique, understanding these factors early helps ensure a smoother building journey.
That's the honest range. A small single storey on a flat, easy-access block in Caboolture sits near the bottom. A 700sqm double storey on a sloping Bridgeman Downs lot, with asbestos and a sewer line running under the old slab, pushes toward the top.
At Ownit Homes, we believe building should come with clarity, not surprises. This guide provides an honest look at the factors that influence the cost of a knockdown rebuild, so you can move forward with confidence.
What You're Actually Paying for in a Knockdown Rebuild
A knockdown rebuild cost splits into three stages. Demolition, site preparation, and the rebuild itself. Site preparation is often overlooked, but understanding it early allows you to budget more accurately and avoid unexpected surprises.
| Stage | What it covers | Typical Brisbane range |
|---|---|---|
| Demolition | Council approvals and demolition works coordinated through trusted specialists | $30,000 to $50,000 |
| Site preparation | Soil testing, contour survey, earthworks, service relocation | $5,000 to $30,000+ |
| Rebuild | Slab, frame, fitout, fixed inclusions, council certification, QBCC insurance | $400,000 to $1,000,000+ |
The hidden cost are found in the site preparation stage. Depending on site conditions, additional work may occasionally be required. An experienced builder will identify many of these factors early during the pre-construction stage to minimise surprises.
How Much Does it Cost to Demolish a House in Brisbane?
Demolition in Brisbane typically runs $30,000 to $50,000 for a standard detached home. It covers labour, machinery, waste removal and tipping fees for a straightforward job. Some factors, such as asbestos removal or difficult access, can influence demolition costs, which is why a thorough assessment before works commence is important.
Existing underground services and previous structures are assessed during pre-construction to help identify any factors that may influence the new home's design or site works.
However, recycled hardwood timber and terracotta roof tiles still hold value across Brisbane. If your demolisher resells them, that value should be deducted from your demolition costs. Ask before you sign.
Understanding Site Preparation Costs
This is the section other guides skip. Site prep on a Brisbane KDR runs anywhere from $5,000 on a flat, easy block to $30,000+ on a sloping site with bad soil and services in the wrong place.
At Ownit Homes, this pre-construction stage is $3,300 and includes soil testing, contour survey, working drawings, and the PCG pre-lim report. This provides a clear understanding of your site conditions and ensures everything is properly prepared before construction begins.
Depending on your block, there may be additional site considerations such as earthworks, retaining, or service adjustments. These are managed as part of the early planning process, and we work alongside relevant specialists where required to keep everything aligned and moving smoothly.
How Much Does the Rebuild Itself Cost?
Cost per square metre in Brisbane in 2026 sits roughly at $1,500-$2,200/sqm for single storey and $1,800-$3,000/sqm for double storey at builder-included finishes. Premium custom builds run higher. Here's how that translates to total build cost by size, before site costs.
| Home size | Single storey | Double storey |
|---|---|---|
| 200 sqm | $300,000 to $440,000 | n/a |
| 300 sqm | $450,000 to $600,000 | $540,000 to $900,000 |
| 400 sqm | $600,000 to $880,000 | $720,000 to $1,200,000 |
| 500 sqm+ | $750,000 to $1,000,000+ | $900,000 to $1,500,000+ |
Classic vs Dream Inclusions
At Ownit Homes, every design comes with a clear choice between two inclusion levels: Classic and Dream. Both are built around quality, transparency, and certainty, the difference comes down to the level of finish you want from the start.
Classic covers all the essentials needed to build a high-quality home without unnecessary extras. You still get durable materials, reliable appliances, and thoughtfully selected finishes, just without the premium upgrades.
Dream is our elevated standard. Think stone benchtops, upgraded flooring, premium tapware, and designer-level finishes throughout. Instead of treating these as costly upgrades later, they’re included from the outset.
What many builders charge as variations during the build, we include upfront in your chosen level. That means fewer surprises, fewer change orders, and a more predictable build journey.
All selections are finalised before construction begins in our Dream Studio at Upper Mount Gravatt. Here, you’ll work directly with a qualified Colour Consultant to make every interior and exterior choice in one place, before the slab is poured.
Because your inclusions are locked in early, your contract price is designed to stay consistent, reducing variation costs and keeping your final number aligned with what you signed.
Where Knockdown Rebuilds Make the Most Sense in Brisbane
With Brisbane's ongoing housing shortage and the limited supply of well-located land, finding the perfect block has become increasingly difficult. For many homeowners, a knockdown rebuild is now the most practical and cost-effective way to secure a brand-new home without leaving the suburb they already love.
Rather than competing for vacant land or compromising on location, rebuilding allows you to maximise the potential of your existing block while enjoying a modern home designed for today's lifestyle.
Knockdown rebuilds are particularly popular in established suburbs with generous block sizes and older homes ready for renewal. This includes Bridgeman Downs, Aspley and Bald Hills on Brisbane's northside; Rochedale, Mount Gravatt and Wishart on the southside; Wynnum, Manly and Redland Bay in the bayside region; and Springfield and Karana Downs in Brisbane's western corridor. If you're considering rebuilding in character suburbs such as Paddington or Wilston, it's important to check local demolition controls and character overlay requirements before getting started.
Ownit Homes builds across the Greater Brisbane region, from Caboolture and Bribie Island in the north, to Coolangatta in the south, and west to Kalbar, Boonah and Rosewood. Wherever you're located, our team can help you determine whether a knockdown rebuild is the right solution for your block.
Why a Debt-Free Brisbane builder
A 20-year structural guarantee is only worth something if your builder is still trading in year 15. That's the part most homeowners don't think about until the news runs another story about a builder collapse.
Ownit Homes has been family-owned since 1972 and remains proudly debt-free. Today, the business is led by Scott and Brad Ganim, continuing the family legacy that began more than 50 years ago. Our long-term approach means we're focused on building quality homes and lasting relationships, not short-term results. With decades of experience, financial stability, and a commitment to transparency, you can feel confident knowing your home is being built by a trusted Queensland builder.
We're QBCC Licence 006479, members of HIA and Master Builders Queensland, and every home gets a 20-year structural guarantee in writing. That's the difference between a number on paper and a number you can stand behind in 2046. See how we structure a knock down rebuild Brisbane project from contract to handover.
Brisbane Knockdown Rebuild, Your Questions Answered
How long does a knockdown rebuild take in Brisbane? Demolition takes 1-2 weeks. Design, approvals and pre-construction run 3-6 months. Build time is typically 6-10 months for single storey and 9-14 months for double storey. Total from signed contract to handover: 10-18 months.
Can I live on site during the build? No. Once demolition starts, the block is a construction site and is not safe or insurable for occupation. Most clients rent nearby or stay with family. Factor 12-18 months of rent into your budget.
Do I need council approval to demolish my house? Yes. Brisbane City Council requires building certification for demolition at $1,580.20 per assessment in 2025-26. Character overlay and demolition control precincts have extra restrictions.
Can I knock down and rebuild in a character zone? Sometimes. Pre-1947 homes in Brisbane character residential zones often can't be demolished without specific approval. Check the BCC City Plan overlay for your address before you sign anything.
Is a knockdown rebuild cheaper than buying a new home? Usually yes, because you skip stamp duty on the land. On a $700k Brisbane property, that's $20k+ saved. You also get exactly the design you want on land you already know. For the full breakdown, see our guide on Brisbane knockdown rebuild specialists .
