FAQs

Questions about rebuilding?

We answer the most common questions about knockdown rebuilds in Sydney including approvals, timelines, and pricing.

Got more questions?

How much does a knockdown rebuild cost in Sydney?

Knockdown rebuild costs in Sydney typically range from $600,000 to $1,200,000+, depending on the design, block size, soil conditions, slope, and finish level. Demolition and site clearance alone can cost $30,000 to $60,000 depending on asbestos and access. We provide detailed, line-item quotes that separate demolition, site prep, construction, and finishes so you can see exactly where the money goes. Book a free planning call to discuss your project.

What does it cost to build a new home?

New home construction in Sydney typically costs $2,000 to $4,000 per square metre, depending on design complexity, finishes, and site conditions. A 250sqm home could range from $500,000 to $1,000,000 in construction costs alone, before demolition and site prep. We provide honest, itemised pricing so you can compare inclusions properly. Read our building contract checklist to know what should be covered in your quote.

Can I keep my current landscaping, pool and gardens?

It depends on your site access and new home footprint. Existing pools, retaining walls, and established trees can sometimes be retained. Mature trees may be protected by council tree preservation orders. We assess this during the site visit. See our knockdown rebuild service.

What are the pros and cons of a knock down rebuild over a renovation?

A knockdown rebuild gives you a brand-new home designed exactly to your needs, with modern insulation, wiring, and plumbing throughout. It often costs less per square metre than a major renovation on an older structure, where hidden issues (asbestos, termite damage, non-compliant wiring) can blow out the budget. A renovation keeps the home's existing character and may be faster if the structure is sound. We help you weigh up both options at the site visit.

Can you knockdown rebuild your home if you still have a mortgage?

Yes, but you will need lender approval. Most banks allow it if the property value and your equity support it. Your lender will want to see approved plans and a signed building contract before releasing funds. Check with your lender early in the process.

What is included in a knockdown rebuild quote?

Our knockdown rebuild quotes cover demolition, asbestos removal (if required), site clearance, design, council approvals (DA or CDC), and full construction costs including all trades, materials, and finishes. Everything is broken down line by line. We also include HBCF insurance on every qualifying project, which is mandatory in NSW for work over $20,000.
