2. Design & Engineering (Optional)

Once your concept is confirmed, design and engineering is required before we can provide final pricing and commence construction.

You can either:

  • Organise your own designer/architect/engineer, or
  • Engage ADG to manage design and engineering for an additional fee


This stage ensures the extension is compliant, buildable, and properly planned before construction begins.

3. Prelim Stage (Selections & Planning)

Fee: $499 – $999

Once design and engineering is ready, we move into our Prelim Stage.


This includes:

  • Detailed project review and scoping
  • Site investigation and feasibility checks
  • Preliminary planning and project setup
  • Selection guidance (tiles, fixtures, colours, finishes)
  • Build strategy and sequencing planning


*The Prelim fee is fully deducted from the final contract price if you proceed with ADG.

4. Final Quotation & Contract

Once selections and scope are finalised, we issue a full formal quote and contract with clear inclusions, timelines, and expectations.


This is where your project becomes fully locked in.

5. Construction Phase

Construction Timeframe: ~3 to 9 Months


After contracts are signed, your project enters the construction phase.

Timeframes generally range from:

  • 3 months (smaller extensions / renovations)
  • Up to 9 months (larger structural extensions)


What happens during this stage:

  • Start date confirmed
  • Site establishment and safety setup
  • Structured trade scheduling
  • Weekly progress and clear communication



Clear Communication From Start to Finish

You will have direct contact with your assigned site supervisor throughout the project.

You can expect:

  • Regular schedule updates
  • Onsite coordination of trades
  • Ongoing communication and progress tracking
  • Quick responses to questions and variations


6. Handover & Final Walkthrough

Once works are complete, we conduct a full walkthrough with you to ensure everything meets expectations.


At handover we will:

  • Complete a final inspection together
  • Note any minor defects/omissions (if required)
  • Rectify outstanding items quickly
  • Provide a smooth final sign-off process


We aim to make the handover experience exciting, not stressful.
