— Size. Double and oversized garages need proportionally more slab, frame and roofing.

— Construction type. Steel kits are the budget option; brick or rendered block construction costs roughly half as much again.

— Slab & site works. Cut-and-fill on sloping blocks and thicker slabs add to the groundwork bill.

— Doors & electrical. Auto sectional doors, lighting and power points add $2,000–$6,000 over a bare shell.

— Approvals. Council permits, engineering drawings and boundary setback issues add cost and time.

— Get the slab included in the quote — 'from' prices for kit garages often exclude it.

— Any electrical work must be done by a licenced electrician, including the auto door circuit.

— Think about future use — an extra course of height or a workshop bay is cheap now, expensive later.
