How to Plan a Knock Down Rebuild in Melbourne: Step by Step

Step 1: Assess Whether Your Block and Budget Suit a Rebuild

Before you fall in love with a floor plan, confirm that a rebuild is actually the right answer for your block and your budget.

A few practical questions to answer early:

• Does your block suit a new home? Slope, orientation, easements, tree protection overlays and local council requirements all influence what can be built. A sloping site in the hills is entirely workable, but it needs to be designed for from the beginning.

• How does a rebuild compare with renovating? If the existing structure is sound and the layout can be adapted, a major renovation may deliver what you need for less. If the home is outdated, poorly insulated or the wrong footprint entirely, a rebuild usually offers better long-term value and a much lower maintenance burden.

• What is your realistic budget? A knock down rebuild typically involves demolition, design and documentation, permits, authority fees, site works, construction and landscaping. Understanding the whole cost picture early prevents difficult conversations later.

Step 2: Understand the True Cost of a Rebuild

Quotes for new home construction are usually expressed as a price per square metre, but the final figure depends on far more than floor area.

Costs to plan for include:

• Demolition, asbestos removal and site clearance

• Soil testing, engineering and surveying

• Architectural design, drafting and building documentation

• Planning permits and building permits, plus council and authority fees

• Site preparation, retaining walls, drainage and connection to services

• Construction of the home itself, including fixed and provisional items

• Driveway, fencing, landscaping and any pool or outdoor structure

The most common cause of budget stress is not the build itself - it is the items that were never included in the first estimate. A transparent builder will walk you through every allowance and provisional sum, and tell you clearly what is fixed and what may vary.

Step 3: Design Your New Home Around How You Actually Live

This stage is where a rebuild becomes personal. A custom home should reflect the way your family moves through a day: where the morning light falls, where the kids do their homework, where you entertain.

Bring the builder into the process early. When design, engineering and construction are aligned from the start, you avoid the expensive rework that happens when a plan cannot be built the way it was drawn.

Step 4: Navigate Permits and Approvals

Approvals are the part of the process homeowners worry about most, largely because the rules vary between councils and can feel opaque.

There are generally two approvals to manage:

Planning permit. Required when your proposal does not meet the requirements of the local planning scheme - for example, where a variation to setbacks, height or site coverage is needed. Your council assesses this against its planning scheme and neighbourhood character guidelines.

Building permit. Required for all building work. This is issued by a registered building surveyor and confirms the plans comply with the Building Regulations, the National Construction Code and relevant Australian Standards.

Timelines vary. Some approvals move quickly; others involve neighbours, objections or heritage and vegetation overlays. A builder who knows the local councils can prepare for these requirements rather than be surprised by them.

Step 5: Choose the Right Builder

This is the decision that determines whether the next twelve months are calm or chaotic. Look for:

• Evidence of completed local work. Ask to visit a finished home or a project under construction.

• A detailed, itemised quote. Vague pricing is a warning sign. You should see the scope in writing.

• A realistic timeline. Optimistic schedules that ignore approvals and weather are not helpful.

• Clear communication. You should know who your point of contact is and how often you will hear from them.

• Proper insurance and registration. Confirm the builder is registered and carries the required domestic building insurance.

A good builder will also tell you when something is not worth doing. That candour is worth more than any sales pitch.

Step 6: Demolition and Construction

Once approvals are in place, demolition begins. The block is cleared, services are disconnected or protected, and site establishment follows.

From there, the build typically moves through the stages in sequence: slab or footings, frame, roof, lock-up, fit-out and finally completion. Each stage should come with a clear milestone and a progress payment tied to actual work completed.

Step 7: Handover and Beyond

Before handover, you should receive your occupancy permit, a full set of compliance certificates, warranty documentation and a maintenance guide. Walk through the home carefully, note anything that needs attention, and confirm the defect liability period in writing.

After you move in, a builder who stands behind their work will follow up. Good builders do not disappear at settlement.
