New Build Interior Design: What to Plan Early

On a new build, the interior is decided much earlier than most people expect. A power point, a pendant or a pantry wall costs little to move on paper and a lot to move once the frame is up. This guide goes through the interior decisions that belong at the start, in the order a build needs them.

Review the plans before they're locked

Walk the drawings like you'll walk the house

Plans show rooms. They don’t show where the sofa goes, whether the fridge door clears the island or how you’ll carry shopping from the garage to the kitchen. Before sign-off, go through the drawings room by room. Start at the front door and finish on the deck, and furnish each space to scale as you go.

On the Gold Coast, check where the afternoon sun will land, where sliding doors stack and whether the living room still works with the doors open. Small changes at this stage can make a big difference: a wider hallway, a moved window or a reversed door swing. Space planning is really just this exercise done carefully.

Check furniture sizes against walls · door swings and stacking doors · window heights behind benches and beds · storage in every room, not just the bedrooms

Power, light & switching

The electrical walk-through comes early and changes are hard to make later.

Power where life happens

Place outlets for the furniture plan, not the empty room. Think about bedside charging, a point in the island, the entry console and the TV wall. Plan a hidden appliance zone so the benchtops stay clear.

Light in layers

A grid of downlights is the default for a reason, but it rarely suits a home. Pendant positions depend on the island size, and wall lights depend on bed width. Our lighting design guide covers the layers in detail.

Switches that make sense

Put switches on the side of the door you walk in on. Add two-way switching on stairs and in long halls, and put dimmers where evenings are spent. Mark the height of every switch and outlet where it sits against joinery or tiles.

Joinery & selections

Built-in joinery affects plumbing, electrical, ceiling heights and wall framing. Design the kitchen, laundry, robes and vanities while the walls can still move. Then add the blocking for wall-hung vanities and floating shelves before the plaster goes on. See custom joinery design and the kitchen design guide.

Choose floors, tiles, benchtops, tapware and paint as one palette, not one item at a time from a builder’s range. Some finishes change set-out and fixing details, so settle them early. Colour & material selection keeps the choices consistent from room to room.

Put it all in documents a builder can follow

Decisions that live only in emails and showroom notes tend to get lost on site. Clear design documentation means joinery drawings, electrical and lighting plans, tile set-outs and a finishes schedule. It gives your builder something to price and something to build from, and it gives you a way to check the work at each stage.
