Knockdown And Rebuild To Stay Where You Are

Stay where you love. Live how you want.
If your block is perfect but your house no longer fits, a knockdown rebuild lets you start fresh on the same land. We handle everything, from feasibility and approvals to demolition and a turnkey new home.
You keep your address, schools, and the community you value, without the compromises of a renovation.

Why A knockdown rebuild instead of renovating?

  • Keep the location you love while upgrading every square metre
  • Design for your life: plan, flow, storage, and features your old home can’t support
  • Modern performance: energy efficiency, insulation, glazing, smart systems
  • Cost control: fewer unknowns than major renovations with hidden structure issues
  • Increase value on a desirable block with a new, architecturally led home

Why Choose Phase Projects for Your KDR?

We work across the Eastern Suburbs, Inner West, and Southern suburbs down to the Sutherland Shire.
Where land is scarce, we design smarter, with split levels and where appropriate we can add roof top living as well as basements to reclaim outdoor space and add parking, storage, gyms, or cinemas (subject to council controls).

Ready to explore your block’s potential?

Bring your ideas or existing plans. We’ll map the approvals pathway, timeline, and budget drivers and show you how to get the most from your land, without leaving your neighbourhood.

Important considerations For Building Development in Sydney

  • Demolition scope & cost vary with house size, access, materials, and hazardous materials removal
  • Approvals pathway: DA vs CDC depends on zoning, height, setbacks, streetscape, flooding, heritage
  • Site conditions (rock, fall, drainage) shape design and budget—testing early removes surprises
  • Temporary accommodation may be needed during demolition and build
  • Future flexibility: plan for multi-generational living, rental potential, or resale from day one

After 20 years of building homes in Sydney, we have built all sorts of homes and dealt with all planning, design and approval scenarios!

A knockdown rebuild involves demolishing your existing house and constructing a brand-new custom home on the same block. It allows you to stay in the location you love while upgrading to a modern, functional home.

If asbestos is present, it must be safely removed by licensed professionals before demolition can proceed. We arrange all necessary assessments and removal.

Renovations often come with hidden costs and limitations due to the existing structure. A knockdown rebuild gives you a fresh start with a brand-new design, often proving more cost-effective than extensive renovations.
