One of the most common questions homeowners ask before starting a project is:

How long will this actually take?

In South East Queensland, the timeline for designing and building a new home or major renovation typically ranges between 12 and 24 months, depending on complexity, approvals, and construction scale.

Below is a realistic breakdown of each stage.

‍

Stage 1: Concept Design

Timeframe: 4 to 8 weeks

This is where the overall vision is developed.

It includes:
• Site analysis
• Initial layouts
• Design direction
• Early budget alignment

Complex sites or multiple design options can extend this stage slightly.

‍

Stage 2: Architectural Planning & Approvals

Timeframe: 2 to 4 months

This stage involves refining the design and preparing documentation for approvals.

Time depends on:
• Whether a Development Application (DA) is required
• Heritage or character overlays
• Flood or zoning constraints
• Consultant coordination

If council approval is required, allow additional time for assessment.

‍

Stage 3: Building Approval

Timeframe: 4 to 8 weeks

Once planning approval is secured (if required), building approval is sought through a private certifier or council.

This includes:
• Structural engineering
• Energy compliance
• Finalised documentation

Delays often occur if documentation is incomplete or revisions are needed.

‍

Stage 4: Builder Pricing & Contract Signing

Timeframe: 4 to 8 weeks

Builders review documentation, obtain subcontractor quotes, and prepare final pricing.

Complex renovations can take longer due to unknown site conditions.

‍

Stage 5: Construction

Timeframe: 6 to 12 months

Construction timelines vary significantly depending on:

• Size of the project
• Weather conditions
• Builder workload
• Material availability
• Structural complexity

For reference:

• Medium renovation: 6 to 9 months
• Large renovation or new home: 9 to 12 months
• Highly complex or high-end builds: 12 months or more

‍

What Causes Delays in Queensland?

Common causes include:

• Council approval hold-ups
• Weather events
• Variations during construction
• Delayed material selections
• Incomplete documentation at tender stage

Early planning significantly reduces time blowouts.

‍

Realistic Overall Timeline

For a typical new home or major renovation in Brisbane or the Gold Coast:

• Design: 2 to 4 months
• Approvals: 2 to 4 months
• Construction: 6 to 12 months

Total: Approximately 12 to 18 months

More complex projects may extend beyond this.

‍

Final Thoughts

Designing and building a home is not a quick process.

However, projects that invest time in early design and documentation often experience fewer construction delays and cost overruns.

If you are planning to build in Queensland, it is wise to begin discussions 12 to 18 months before your ideal completion date.
