A successful building project usually starts with a careful brief and realistic expectations. Use the steps below as general planning guidance; exact legal and technical requirements vary by state, council and project.
Define the extra space
Write down the rooms you need, the problems with your existing layout and the priorities you will not compromise on.
Get the right design input
An architect, building designer or engineer may be needed for feasibility, planning and structural questions. Local approval rules vary.
Consider living arrangements
Discuss dust, noise, access and whether you can safely occupy the home during work. Temporary accommodation may be worth budgeting.
Include a contingency
Older buildings can hide wiring, moisture or structural issues. A contingency and clear process for unexpected work can reduce avoidable disputes.
For project-specific advice, consult licensed building professionals and relevant government authorities. This guide is general information, not legal, financial, planning or engineering advice.
