Read articleHave a question that is not covered? Ask the builder directly.
Ask a questionEvery residential builder in NSW must hold a current licence issued by NSW Fair Trading. You can verify any builder by searching their licence number on the Fair Trading website. For work valued over $20,000, builders must also carry HBCF insurance. METCON holds builder licence 384697C and DBP registration BUP4254812.
Sydney build costs vary widely with site conditions, finishes and complexity. As a rough guide for 2026: a standard single-storey extension runs $3,200–$4,800 per m²; a high-end custom home is $5,500–$8,500+ per m²; commercial fitouts range $1,800–$3,500 per m². We always provide a free, line-item written quote.
A properly insured builder carries: Public Liability (minimum $20m), Workers Compensation, Contract Works / All-Risk insurance, and HBCF cover for residential jobs over $20k. Ask to see certificates of currency before signing. METCON carries all four.
Under the Home Building Act 1989, builders cannot demand more than 10% deposit on jobs over $20,000. Payments must be tied to defined stages (base, frame, lock-up, fixing, completion). A reputable builder will never ask for large upfront cash or money outside the contracted schedule.
A builder holds the construction licence and warranty. A project manager oversees programme, budget and quality but does not hold the licence. A head contractor is a builder who also subcontracts and coordinates trades. METCON operates as a head contractor, one contract, one point of responsibility.
Often yes for cosmetic renovations and most rear extensions. Underpinning, top-floor additions, kitchen relocations, and major structural work usually require relocation for safety. We do a “stay vs go” assessment as part of every quote.
NSW residential work is covered by statutory warranties: 6 years for major defects (structural, waterproofing, fire safety) and 2 years for all other defects. These cannot be contracted out of and apply even if the builder goes out of business.
Three is the sweet spot. What matters is comparing like-for-like scope, not just the bottom-line number. Look at inclusions, exclusions, allowances and the builder's recent reference projects.
Watch for: no fixed business address, unverifiable licence, requests for cash deposits, vague quotes, no written contract, no insurance certificate, refusal to provide references, pressure to sign on the spot, or unusually low pricing.
Drawings never cover every condition on site. A builder who can read engineering drawings and call the engineer directly saves days or weeks of rework. Our team has worked alongside structural and geotechnical engineers for 40+ years.
