Knockdown Rebuild Brisbane

A knockdown rebuild can give you a completely new home without leaving the suburb, school area or community you already know.

It can be a strong option where the existing house no longer suits your family and a major renovation would involve too many structural or layout compromises.

B Ward Constructions builds custom new homes across Brisbane, including infill projects on established residential blocks.

Brodie Ward is directly involved in reviewing the site, planning the build, coordinating trades and checking the work through to final handover.

Is a Knockdown Rebuild Right for Your Property?

The first step is not demolition.

Before committing to the project, the property and existing house need to be checked to determine whether demolition is permitted and whether the proposed new home can be approved and built within your budget.

A knockdown rebuild may suit you if:

  • You want to stay in the same Brisbane location

  • The existing layout would require extensive compromise

  • The home needs major structural and service upgrades

  • You want a layout designed specifically for your family

  • The block can support the size and style of home you need

  • Building new offers better value for your goals than a major renovation

Check Demolition Controls First

Not every Brisbane house can be demolished.

Planning approval may be required where the property:

  • Is a local or state heritage place

  • Is affected by the Pre-1911 building overlay

  • Is within the Traditional building character overlay

  • Contains a protected character building

  • Is affected by demolition provisions within a neighbourhood plan

Planning approval is generally required to demolish an entire building built before 1946 within the Traditional building character overlay.

A licensed building certifier should also confirm whether building approval is required for the demolition work.

The demolition pathway should be checked before significant design costs or contractual commitments are made.

Our Knockdown Rebuild Process

1. Initial Feasibility

We discuss the property, the type of home you want to build, your preferred timing and realistic budget expectations.

2. Property Investigation

The project team reviews the site’s zoning, overlays, neighbourhood plan, access, services, flooding, slope, vegetation and other relevant constraints.

A feature survey, soil test and specialist consultant advice may be required.

3. Confirm the Demolition Pathway

A town planner and building certifier can confirm the approvals required to demolish or remove the existing building.

Demolition cannot proceed until the necessary approvals have been obtained and their conditions can be met.

4. Design the New Home

Your architect or building designer develops a home that responds to the block, neighbourhood and applicable planning requirements.

Brodie can provide practical input regarding access, structure, materials, construction sequencing and buildability.

5. Planning and Building Approval

The proposed home is assessed against Brisbane City Plan.

Some houses are accepted development when they meet all applicable requirements. Other projects require a development application because of the site, overlays or proposed design.

Every new detached house also requires building approval from a licensed building certifier.

6. Detailed Pricing and Contract

Once the design, engineering, specifications and selections are developed sufficiently, we prepare detailed pricing.

The building contract records the scope, allowances, exclusions, programme and progress payment stages.

7. Demolition and Site Preparation

The existing building is disconnected and demolished by appropriately licensed contractors in accordance with the approved scope.

The site can then be prepared for set-out, earthworks, services and foundations.

8. New Home Construction

Construction progresses through foundations, framing, enclosure, services, internal finishes, external works and mandatory inspections.

9. Completion and Handover

At practical completion, we inspect the home with you, address agreed minor items and provide the applicable certificates, warranties and product information.

Brisbane Site Items to Investigate Early

  • Whether the existing house may legally be demolished

  • Lot size, frontage and property boundaries

  • Building setbacks, height and site coverage

  • Flooding, stormwater and overland flow

  • Slope, retaining walls and soil conditions

  • Sewer, water and electrical service locations

  • Easements and title restrictions

  • Protected vegetation and significant trees

  • Vehicle and construction access

  • Asbestos within the existing building

  • Footpath and neighbouring-property restrictions

Knockdown Rebuild or Major Renovation?

A knockdown rebuild may provide:

  • A completely new layout

  • New structure and building services

  • Improved energy efficiency

  • Fewer limitations from the existing house

  • A clearer construction process once demolition is complete

A major renovation may provide:

  • Retention of a valued Queenslander or character home

  • Preservation of original features

  • A suitable solution where demolition is restricted

  • The ability to work with an existing structure worth retaining

The right option depends on the property, approvals, existing condition, design goals and total project cost.

Knockdown Rebuild FAQs

Can every Brisbane house be demolished?

No. Heritage, pre-1911, traditional character and neighbourhood planning controls may prevent or restrict demolition.

Do I need approval for both demolition and the new house?

Potentially. Demolition may require planning and building approvals. The new house must also be assessed under City Plan and requires building approval.

Can you build on narrow or sloping blocks?

Yes, subject to the site, access, engineering and planning requirements. These blocks usually require careful survey, structural, retaining and drainage design.

Who organises the demolition?

This depends on the agreed contract scope. Demolition must be completed by appropriately licensed and insured contractors.
