How to Choose the Best Building in Gungahlin
A checklist before hiring any building in Gungahlin, Canberra.
- 1
Verify their electrical licence is current at your state's electrical safety authority (e.g. Energy Safe Victoria, NSW Fair Trading).
- 2
Confirm they carry public liability insurance of at least $5 million — ask to see the certificate.
- 3
Get 2–3 written quotes for any job over $500. A written quote protects both parties and clarifies the full scope.
- 4
Check their Google and TradeRefer ratings — look for consistent reviews mentioning punctuality, clean workmanship, and clear communication.
- 5
Ask whether they'll provide a Certificate of Compliance (electrical safety certificate) on completion, as required by law in most states.
FAQs — Building in Gungahlin, Canberra
How much does a home extension cost in Australia?
A single-storey extension typically costs $2,000–$3,500 per m². A 40m² addition runs $80,000–$140,000 including structural work, roofing, cladding, and fit-out. Two-storey additions cost more due to engineering and structural complexity. Always get a fixed-price contract rather than a cost-plus arrangement.
Do I need council approval for a home extension?
Yes in most cases. Extensions that change the building's footprint, height, or floor area require a building permit and often a planning permit. Some minor works fall under 'exempt development' thresholds — these vary by state and council. Your builder or building designer can advise what approvals apply to your project.
What is the difference between a builder and an architect?
An architect designs the building and may project-manage, but doesn't do physical construction. A builder constructs the project to approved plans. A building designer (draftsperson) produces plans without an architect's full qualification. For most residential projects, a building designer plus licensed builder is sufficient and more cost-effective.
How long does a granny flat take to build in Australia?
A standard prefabricated or modular granny flat takes 12–20 weeks from approval to completion. Traditionally-built granny flats take 16–26 weeks. The approval process (council or CDC) takes 4–10 weeks before construction can begin. Total time from concept to move-in is typically 6–12 months.
What should a building contract include?
A compliant building contract must include: fixed price or schedule of rates, scope of works, start and completion dates, progress payment schedule, insurance details, the builder's licence number, variation process, and dispute resolution procedure. Never pay more than 10% deposit in most states.
