Renovating is as much about planning and process as it is about design — and the mistakes that cost the most are almost always avoidable. These renovation advice guides cover budgeting and contingencies, council approvals and certifiers, choosing and managing trades, the right order to run a project, contracts and progress payments, and how to sidestep the surprises that blow out timelines. Browse the guides whether you're planning your first renovation or your fifth. When it's time to put numbers to your plan, our renovation cost calculator gives realistic 2026 Australian ranges, and the renovation planner turns them into a whole-project budget with a room-by-room checklist. To find and compare vetted trades in your city, use the trade directory. Get three itemised quotes for anything over $2,000, verify licences, and never pay large sums up front.
