Knock Down Rebuild Sydney
Your block. Your suburb. A brand-new home, built exactly the way you want it.
Home Cor Constructions delivers knockdown rebuild projects across Sydney – removing the old and building new, on land you already own. No compromising on someone else’s floor plan. No stamp duty. No starting over in a suburb you don’t know.
Director Anthony Chohaili oversees every knockdown and rebuild personally, from the first site walk to final handover. That’s been the model for more than 25 years, and it’s why the work holds up.

Is a Knock Down Rebuild Right for You?
Some homes just aren’t worth saving. The layout fights you, the ceilings are low, the stumps are moving, and every fix leads to another problem behind the wall. We see it constantly – homeowners who’ve spent years patching a house that needed replacing ten years ago.
A knock-down and rebuild in Sydney gives you a clean start on a block you already own, in the suburb where your kids go to school, and your parents live ten minutes away. You keep the land. You lose the headaches.
It makes sense when the cost of renovation is creeping past what a new build would cost, when the existing structure has issues that won’t go away, or when the block is simply worth more than the house sitting on it. If you’re spending weekends on Realestate.com.au looking for knock-down-rebuild homes that don’t exist, the answer might already be under your feet.
We offer knock-down and rebuilds that cover everything – demolition, council approvals, construction, and completion. Every scope is built around your block, your brief, and your budget.
Most knockdown rebuild Sydney prices for the build component range from $350,000 to $1,000,000+, with demolition typically $15,000 to $40,000, depending on site access and structure. We provide detailed, itemised quotes so you can make informed decisions

What Sydney Homeowners Should Know Before Knocking Down and Rebuilding
The maths on selling and rebuying in Sydney rarely works in your favour. Stamp duty alone on a $1.5 million purchase is over $66,000. Add agent commissions on your sale, conveyancing on both ends, and the premium you’ll pay for a home that still doesn’t suit how you actually live – and the numbers get uncomfortable fast.
The Case for Rebuilding Instead of Selling
A knockdown-and-rebuild in Sydney sidesteps most of that. You keep the land, skip the transaction costs, and build a home designed around your household as it works today. Not how it worked when you bought the place.
Then there’s the build itself. A new home includes modern framing, compliance with current energy-efficiency standards, new electrical and plumbing systems throughout, and a full structural warranty. A knockdown rebuild removes unknowns you didn’t budget for and gives you a new home built to today’s standards.
Planning Approvals – DA vs CDC
One of the first questions we answer on any knock-down rebuild in Sydney is which approval pathway applies.
CDC (Complying Development Certificate): Faster. Processed within 20 business days by an accredited certifier. Suit homes that meet set planning standards – setbacks, height, floor space ratio. Many blocks in Western and South-Western Sydney qualify, and it’s the route we recommend when it’s available.
DA (Development Application): Takes longer – often three to six months or more – but allows greater design flexibility. Required for sites with heritage overlays, unusual block shapes, or where the proposed design falls outside complying development thresholds.
Getting the pathway wrong costs time and money. We assess this before any design work starts.
BASIX compliance is mandatory for all new residential builds in NSW. It sets benchmarks for water use, thermal comfort, and energy efficiency. We factor this into the design from day one – not at the documentation stage when it’s too late to change anything cheaply. A well-designed knock-down rebuild home will meet BASIX comfortably and cut your running costs for the life of the building.
Choosing the Right Knockdown Rebuild Builders
Before you sign with anyone, ask these questions:
- Who will actually be on site overseeing the work? How often?
- How are variations handled – in writing, or verbally with a handshake?
- Can I speak to a past client or walk through a completed home?
- What happens when something goes wrong – because something always does?
Not all knockdown rebuild builders work the same way. Some run volume operations – ten or fifteen sites at once, project managers who visit once a fortnight, subcontractors who’ve never met the client. That model has its place, but it’s not ours.
A builder who can answer those questions directly has thought about how the project actually runs. Not just how it gets sold. Our completed projects are in suburbs you can drive to. Read our client testimonials.
Frequently Asked Questions
Most projects run 10 to 16 months from demolition to handover:
- Approvals: CDC takes 4-8 weeks. DA takes 3-6 months, sometimes longer.
- Demolition: 1-2 weeks.
- Construction: 8-14 months, depending on size and complexity.
Going the CDC route, where your block qualifies, is the single best way to shorten the timeline.
Yes – from demolition day through to handover. Most of our clients rent nearby. Factor in 12-18 months of rental costs when comparing against alternatives. It’s a real cost, and it should be in your budget from day one.
Yes. We work with designs prepared by your architect, building designer, or draftsperson. If you don’t have one yet, we can point you toward people we’ve worked with – no obligation.
The one thing we will push on: documentation needs to be complete and coordinated before construction starts. Gaps in drawings are one of the most common reasons residential builds blow out on cost.
Depends on the scope. Rule of thumb: if a renovation will cost more than 60-70 per cent of a new build, the rebuild deserves serious consideration.
Renovation costs are harder to predict – you don’t know what’s behind the walls until you open them. Older structures often need expensive remediation. A new build comes with a full warranty on everything and far better long-term energy efficiency.
Assessed early, during the DA or CDC process. Many Sydney councils enforce tree preservation orders that protect certain species or trees above a set size. Removing one without approval carries significant fines.
We identify protected trees before demolition planning begins and handle any applications required. If a tree stays, the design works around it.
Potentially, depending on your suburb’s zoning rules. Under the NSW Medium Density Housing Code, dual occupancy is permissible on blocks zoned R1, R2, R3, or RU5 with a minimum lot size of 400m² for an attached duplex. Detached dual-occupancies typically require 600 m² or more. However lot size requirements vary based on council.
We don’t sell packages. Every scope is tailored to your specific block, design, and budget, covering demolition, approvals, construction, and completion.
