Frequently Asked Questions
What is a knockdown rebuild?
A knockdown rebuild means pulling down your old house and building a brand new one on the same block. You keep the suburb, the street and the neighbours you love, and get a home that suits how your family lives now.
How much does a knock down rebuild in Sydney cost?
Costs vary depending on your block size, site conditions, demolition requirements and home design, but most Sydney knock down rebuild projects fall within a broad mid-to-high six-figure range. We provide a tailored, itemised quote after assessing your specific site.
Do you handle demolition?
Yes. Demolition, permits, and disconnection of services (electricity, gas, water) are managed as part of your overall project, so you’re not coordinating separate contractors.
How long does a knock down rebuild in Sydney take?
Most knock down rebuild projects run approximately 9–12 months from demolition to handover, depending on council approval pathway, home size and site complexity. We’ll give you a project-specific timeline after your site assessment.
What are the benefits of a knockdown rebuild?
You get a new home built around your needs without the stress and costs of selling, buying and moving suburbs. It also usually works out cheaper than a big renovation, with better energy efficiency and less upkeep, so ask us to compare the numbers for your place.
Can I customise my new Sydney home design?
Yes. Every home is designed specifically for your lifestyle and block.
Do you need council permission or approvals to demolish and rebuild?
Yes, in NSW demolition and a new build generally need approval through either a Development Application or a Complying Development Certificate. Royal Constructions manages the approvals and documentation, and your council or a certifier confirms the exact pathway for your site.
How can I increase my home’s value by $50,000+ in Australia?
Replacing an outdated house with a modern, energy-efficient home that makes full use of the land is one of the strongest ways to lift value, though results vary by suburb and market. Adding a granny flat or a dual-occupancy layout, where council rules allow it, can add further value.
Why choose Royal Constructions for your knockdown rebuild in Sydney?
Royal Constructions is a family-owned Sydney builder that manages everything from demolition and approvals to handover, with a fixed-price contract and the same team throughout. You also get a free site consultation, so you aren’t coordinating separate contractors.
How do I know if my block is suitable for a new build?
Most Sydney blocks can take a new home, but things like slope, block width, easements, sewer lines, and flood, bushfire or heritage overlays can affect what you can build. We’ll check your site, soil and planning rules early, so book a site assessment before you spend money on plans.
