Most new home problems don’t start on site — they start on paper, weeks before anyone picks up a shovel. A floor plan drawn without the block in mind, a budget set after the design instead of before it, or a builder brought in too late all lead to the same place: rework and delays. None of it is hard to avoid. It just means getting a handful of things sorted before the first concept sketch, not after.

Start With Your Block, Not a Floor Plan 

Every block faces a different direction, sits on a different slope, and comes with its own shape and constraints. A design that ignores this — a plan that puts living areas on the wrong side for natural light, say — ends up needing rework later, at a stage where changes cost more. Before any layout gets drawn, your block’s orientation, slope and shape should decide where the living spaces, windows and outdoor areas go, not the other way round.

Set a Realistic Budget Before the Design, Not After 

A concept that looks good on paper but can’t be built within your budget just gets stripped back later, usually losing the parts you cared about most. Talking through budget honestly at the brief stage — what’s fixed, what’s flexible — means the approved design is one that’s actually buildable, not one that needs a second round of cuts once quotes come in.

Know What Your Council Will and Won’t Allow 

Setbacks, plot ratio, open space requirements and any site-specific overlays — heritage, bushfire, flood — all shape what can be built on your block. Checking these early, against Perth’s R-Codes and your council’s requirements, avoids getting most of the way through documentation before hitting a rule that forces a redesign. It’s far cheaper to build compliance in from the concept stage than to fix it at DA submission.

Decide How You’ll Actually Use the Home 

Bedroom and living room counts are only part of the brief. How many people will actually live in the home, how they move through it day to day, and which rooms matter most — these decisions shape the plan far more than square metreage does. Working through this properly before concept design starts saves reworking the layout later.

Bring Your Design and Your Builder Together Early 

Whether you already have a builder or need help finding one, design and construction work best when they’re talking early, not once drawings are finished. Coordinating documentation with your builder from the start makes pricing more accurate and keeps the project moving once council approval comes through.

Get the Order Right, and the Rest Follows 

None of this needs to be complicated. It just needs to happen in the right order — block and brief first, budget checked early, council requirements built in from the start. Get that sequence right, and the design that gets approved is the one that gets built.
