How much does a house extension cost in Perth?
For 2026, ground-floor extensions typically run $2,800 to $4,500 per sqm depending on spec and site: a 40 sqm extension commonly lands between $120k and $180k; a 60 to 80 sqm open-plan living extension between $180k and $320k.
Sloping blocks, limestone footings and matching character detail move the number, the free consult tells you where yours sits before you spend anything on drawings.
Extend or move? The honest maths
Moving costs Perth families roughly 6-8% of their sale-and-purchase in stamp duty, agent fees and moving costs.
Often $80k to $150k that buys no extra house at all. An extension puts that money into floor area and value instead.
At your free consult we'll talk through both paths honestly; if your block or budget genuinely favours moving, we'll say so. Builders who tell the truth at step one are the ones you trust at step five.
