Love where you live

Keep the land,
Change anything else.

When the neighbourhood still works but the house does not, a rebuild can create a more coherent home around the way your family lives now and may live later.

The opportunity is not simply to replace old with new. It is to rethink light, storage, circulation, privacy, accessibility and indoor-outdoor connection while remaining part of the community you know.

  • Stay close to the people, schools and routines that matter
  • Replace inherited compromises with a layout shaped for daily life
  • Plan for the next ten to twenty years, not only today

Your home, your way

A design pathway
shaped around your life.

The right design response balances how you want to live with what the block, planning context and budget can support.

Understand the block first.
Then shape the right design response.

Block intelligence

  1. Planning

    Approval pathway & design envelope

  2. Site conditions

    Structure & site works

  3. Access & trees

    Demolition & construction planning

  4. Services

    Early risks & coordination

Two design pathways

Choose the level of design response after the block and household brief are understood.

A clearer path to your new home.

From understanding the block to handover, each stage keeps the next decision clear.

  1. Read the block

    Understand the site, household priorities and early project considerations.

    Learn more

    Early priorities, available block information and project constraints help frame the questions that may need further evidence.

  2. Shape the home

    Develop the right design response for the block and the way you want to live.

    Learn more

    The design direction is shaped around the site, household brief and practical project boundaries.

  3. Clarify the project

    Confirm the design direction, site requirements, approvals, scope, allowances and early budget picture.

    Learn more

    A knockdown rebuild budget is more than the build price. The agreed pathway should clarify inclusions, exclusions, allowances and the wider project picture before construction moves forward.

  4. Move into delivery

    Prepare the site and progress through construction with clear communication and agreed milestones.

    Learn more

    Site preparation, construction sequencing, inspections and project communication follow the agreed delivery pathway.

  5. Welcome home

    Complete final checks, documentation and handover.

    Learn more

    Final checks, agreed rectification items and handover information complete the project pathway.

Timing varies by site conditions, approvals, project scope and consultant availability.

Knockdown Rebuild FAQ

Questions worth answering early.

These answers are general planning information. Property-specific advice, scope and responsibilities need to be confirmed for the individual project.

Is it better to renovate or knock down and rebuild?

There is no universal answer. It depends on the condition and usefulness of the existing home, the changes required, the block, planning context, future needs and whole-project budget. Comparing defined pathways is more reliable than relying on a general rule.

How can I understand whether my block may be suitable?

Early questions commonly include zoning, dimensions, access, slope, easements, trees, services and the kind of home being considered. Formal conclusions may require surveys or specialist advice.

Can an existing plan be adapted to the block?

That depends on the plan, site, structure, planning requirements and permitted design changes. A block review helps frame whether adaptation or a custom response is worth exploring.

Can the home be designed fully from the ground up?

A custom design pathway may be worth exploring when the site, household brief or architectural direction calls for an individual response. The appropriate pathway should be discussed after the block and project priorities are understood.

What should I budget for beyond the new-home build price?

Depending on the property and project scope, a knockdown rebuild may also involve demolition, site preparation, investigations, approvals, authority requirements and site works. Your project-specific proposal should clarify the agreed inclusions, exclusions and allowances.

What needs to happen with the existing home?

Demolition planning may involve approvals, service disconnections, site access, hazardous-material checks, accommodation and coordination with the agreed build programme. Who arranges each item must be confirmed for the project.

How long does a knockdown rebuild take?

The journey includes investigation, design, scope development, approvals, preparation and construction. Timing varies, so stage-specific expectations are more useful than one universal promise.

Will the project need a CDC or a DA?

The pathway depends on the property, planning controls and proposal. Eligibility should be checked before design, budget or timing is treated as settled.
