WONDERING HOW MUCH AN INTERIOR DESIGNER COSTS IN BRISBANE? One of the first questions people ask when they're planning a renovation or building a home and thinking of hiring a designer is: "How much does an interior designer cost?" As a general guide, interior designers in Brisbane can charge anywhere from around $100–$250+ per hour for consultations and smaller pieces of work, while larger projects are often priced as a fixed fee based on the scope involved. For full interior design, fees can range from a few thousand dollars for a smaller project to tens of thousands for a large renovation or new build. The biggest factor isn't necessarily the size of your home, but how much design work, documentation and ongoing involvement your project requires.
