Good interior design is what makes a renovated house feel finished — colour, texture, lighting and the way a room is styled matter as much as the build. These interior design ideas cover colour schemes and paint, styling and decor, lighting design, window treatments, flooring and materials, and the trends worth following (and the ones to skip) in Australian homes. Browse the galleries for inspiration across every room, then bring your scheme to life: our painting cost calculator ranges 2026 per-square-metre prices, and the renovation planner helps you budget a full fit-out. For painting, flooring or built-in joinery, the trade directory lists painters and specialists near you. Design from the fixed things outward — flooring, then walls, then the pieces you can change — and let a consistent palette tie the whole home together.
