The Design Process - Owner Builder Club

Owner Builder Design Process

Design is where your build either sets you up for success or expensive regret.

This stage shapes everything that follows: your budget, approvals, timeline and buildability. Getting it right early saves you stress, variations and costly redesigns later.

Start with your ideas

Before you engage a professional, you need clarity. By now you’ve likely:

  • Saved floorplans

  • Collected Pinterest images

  • Driven past homes you love

  • Noted features that matter to you

That’s great but now it’s time to refine.

Narrow your favourite designs down to 3–5 and identify exactly what you love about each one.

Layout? Natural light? Storage? Flow?

Specificity matters.

Create a clear brief

Your brief is what guides your designer, architect or draftsperson. The clearer your brief:

  • The fewer revisions you’ll need

  • The more accurate your cost estimates will be

  • The smoother your approval process becomes

List what matters most:

  • Lifestyle priorities

  • Must-haves vs nice-to-haves

  • Budget expectations

  • Site constraints

If you’re unsure how to structure this properly, the Pre-Planning course includes a detailed Design Process worksheet that walks you through it step-by-step.

Concept design

Now your chosen professional turns your brief into initial drawings. Keep these in mind:

  1. If something isn’t in the brief, it likely won’t be in the design.

  2. Changes during construction are expensive.

  3. Always confirm what’s included – and what isn’t.

  4. Understand how your design affects engineering, approvals and site costs.

This is where communication is critical.

Design development

Once the concept is approved, the design is refined into detailed drawings.

This stage includes:

  • Structural considerations

  • Compliance requirements

  • Site-specific adjustments

  • Documentation needed for permits

The better your concept clarity, the smoother this phase becomes.

Final documents

This is where everything becomes locked in. If your designer is managing approvals, documentation will be prepared for submission.

Before signing off:

  • Review every room

  • Walk through the layout mentally

  • Confirm measurements

  • Check orientation and window placement

Big tip BEFORE you finalise

Don’t just look at plans, experience them.

  • Mark out rooms on the ground with a tape measure and spray paint so you can feel the real scale.

  • Then print the plans to scale and do a slow “walk-through” room by room to sanity-check flow and layout.

You’ll catch problems early before they become expensive changes.
