It’s the smartest way to get the modern, efficient home you deserve without sacrificing your perfect location. Browse our knockdown rebuild portfolio to see what’s possible.
Why Choose a Knockdown Rebuild Sydney?
A knockdown rebuild Sydney is often cheaper and less stressful than a major renovation or extension. Here’s why more homeowners are choosing this path.
1. Zero Compromise Design
Start with a clean slate. Design a layout, choose modern features, and create the exact flow your family needs – no more working around old walls or awkward floor plans. Explore our custom home designs for inspiration.
2. Built‑in Efficiency
Your new home will be built to the latest standards – better insulation, updated wiring and plumbing, and energy‑efficient features that save you money on bills. As experienced knockdown rebuild Sydney specialists, we prioritize sustainability.
3. Stay Where You Belong
Keep the kids in their schools, stay close to your friends, and keep that favourite local coffee shop. You keep your community; we just upgrade your house. Learn why JS Construction is among Sydney’s award‑winning builders.
4. Clarity on Cost
Unlike major renovations where hidden structural issues blow the budget, a new build means clear, fixed pricing upfront. See our fixed‑price tender process.
Our 4‑Step Knockdown Rebuild Journey
We handle all the heavy lifting – from the first permit to the final coat of paint – so you can focus on planning the furniture. Here is how our knockdown rebuild Sydney process works.
Step 1: Vision & Feasibility
We assess your block, discuss your dream design, and confirm everything is possible and compliant with local council rules. We also check for any site constraints like easements, soil conditions, or heritage overlays. Read our FAQs about council approvals and site feasibility.
Step 2: Permits & Prep
We manage all the approvals – including Development Applications (DA) or Complying Development Certificates (CDC). We also coordinate service disconnections (power, water, gas, NBN) and arrange safe, professional demolition of the old house. Learn more about our demolition and approval process.
Step 3: The Build
With a clean slate, your dedicated project manager oversees the entire construction of your brand new custom home. We use digital project management tools so you can see real‑time progress, photos, and updates from your phone. Weekly meetings, quality control, and WHS safety are standard.
Step 4: Welcome Home
We hand over the keys to a stunning, modern home that is ready for you to move into and start making new memories. We also provide a comprehensive post‑handover service for any minor settling issues. Contact us to start your knockdown rebuild journey – we are ready when you are.
Knockdown Rebuild vs. Renovation – Which Is Right for You?
Many Sydney homeowners face this decision. Here is a quick comparison to help you choose.
When a Knockdown Rebuild Makes Sense
- Your house has structural issues (cracked foundations, termite damage, asbestos).
- You want a completely different floor plan (open plan, second storey, better flow).
- Your home is old (poor insulation, old wiring, inefficient layout).
- You want modern energy efficiency (solar, double glazing, 7‑star rating).
When Renovation Might Work
- Only one room needs updating (e.g., a new kitchen or bathroom).
- The existing structure is sound and the layout already works well.
- You have heritage restrictions that limit demolition.

Frequently Asked Questions
How much does a knockdown rebuild cost in Sydney?
Costs vary based on block size, demolition complexity, and the new home design. As a guide, expect $3,000–$5,000 per square metre for the new build, plus $15,000–$30,000 for demolition. We provide a fixed‑price quote after our feasibility assessment.
How long does a knockdown rebuild take?
Typically 12–18 months from start to finish, including demolition, council approvals, and construction.
Do I need to move out during a knockdown rebuild?
Yes. Your property must be vacated during demolition and construction. Most homeowners rent temporarily or stay with family. We help you plan the timeline.
Can I live in my house during demolition?
No. Demolition is unsafe for occupancy. You will need to move out before demolition begins.
Do you handle all the approvals?
Yes. We manage all council approvals – DA or CDC – as part of our service. We also coordinate service disconnections and site preparation.
Do you offer dual occupancy as part of a knockdown rebuild?
Absolutely. Many homeowners choose to build dual occupancy homes (duplex or detached secondary dwelling) on their existing block after demolition. Explore our dual occupancy home designs.
