What affects the cost of home extensions in Queensland?

The main variables are size, structure and site and design, approvals and specification. Photos and measurements can help with an initial response, but some jobs need an on-site assessment before a firm quote is possible.

Does home extensions require a Queensland licence?

Queensland building-work licensing depends on the exact scope, contract value and exemptions. Confirm the required QBCC class before accepting a quote.

How do I compare home extensions providers?

Compare the same written scope, provider credentials, insurance, product or workmanship warranties, start timing, exclusions and total price. Do not compare headline totals until the inclusions match.

What should I prepare before requesting quotes?

Prepare safe-to-take photos, relevant measurements, the property location, preferred timing and notes about concept, plans and additional area and structure, services and finishes. Never enter an unsafe area just to gather quote information.
