What Happens After Your DA Is Lodged? How to Get Builder Ready for a High-End Renovation

Lodging your DA is a huge milestone—but what happens next can determine whether your renovation stays on track.

For high-end projects (think $1.5M+), the decisions you make now will directly impact budget, timeline, and design integrity. Builders need detailed documentation to quote with confidence, and engaging your interior designer early is the key to avoiding costly surprises later on.

This guide breaks down exactly how to use the post-DA window to get builder ready and why it’s one of the smartest things you can do for your project.

Don’t Pause After Lodging Your DA—Start Designing

Many homeowners see DA submission as a natural pause point, but it’s actually the perfect time to begin interior concept development. Engaging an interior designer now helps establish a clear direction and sets your renovation up for success.

During this phase, we help our clients explore:

• Spatial planning aligned with lifestyle

• Material palettes and lighting mood

• The overall design tone and functional flow of the home

  
  

This foundational work means that by the time your DA is approved, you’re ready to move directly into design development without delay.

When is the Right Time to Engage an Interior Designer?

From Concept to Construction - Design Development Essentials

Once your DA is granted, you’ll need to transition from concept to resolved design. This stage is where layout decisions, material selections, and detailed documentation begin to take shape.

Design development includes:

• Kitchen and bathroom layout planning

• Custom joinery and cabinetry design

• Furniture, lighting, and accessories specification

• Layering spatial functionality with aesthetic decisions

  
  

At this level of investment, design-led decisions require time and attention. Engaging your designer early means fewer compromises and a more cohesive, considered outcome.

Your Builder Ready Interior Design Package - What's included

When your design is finalised, we create a comprehensive documentation package to support the builder tender process. This allows you to obtain accurate, comparable quotes and ensures your chosen builder has everything they need to deliver your vision.

Your builder-ready design package includes:

• Floor plans, elevations, and lighting layouts

• Joinery drawings, finishes schedules, and material specifications

• Fixture and fitting selections including stone, tiles, lighting, hardware, and appliances

  
  

Builders working at the high end of the residential market expect this level of detail. It streamlines pricing, reduces variation risk, and gives you leverage when making builder comparisons.

In Summary

If your DA is lodged and you’re planning a high-end renovation or custom build, this is the time to act. Waiting too long to engage your designer can create unnecessary delays and reduce your ability to make strategic decisions.

Use this time to:

• Begin interior concept development

• Transition into design development post-approval

• Prepare a builder-ready documentation package before you go to tender

  
  

Being builder ready isn’t just about keeping things on track. It’s about protecting your investment and ensuring your project delivers on its full potential.

Frequently Asked Questions:

When should I engage an interior designer for a high-end renovation?

Ideally, as soon as your DA is lodged. This gives you time to develop your interior design concept and start detailed documentation before the builder is engaged.

What does builder-ready interior design documentation include?

A complete design package includes floor plans, elevations, finishes schedules, joinery drawings, lighting layouts, and specifications for fittings, fixtures, and materials.

Why is documentation important before getting builder quotes?

Without it, builders are quoting based on assumptions. Detailed documentation allows for accurate pricing, minimises risk, and makes the tender process more transparent.
