Residential Building Services

Your home. Our commitment.

We build and renovate homes for families across Darkinjung, Awabakal and Wonnarua Country — from the Central Coast through Lake Macquarie, Newcastle, Maitland and Cessnock. Whether you're building from the ground up, extending your family home, adding a granny flat, or repairing after an insurance claim, you're working with a licensed NSW builder who shows up on time, quotes fairly, and finishes properly.

Director Brad Robinson is a proud Dunghutti and Wiradjuri man, raised on Darkinjung Country. Koori Constructions is 100% Aboriginal-owned, HIA-accredited, and fully licensed (NSW Licence 477499C). We've delivered over 50 residential projects since 2021 — from studio granny flats to full-home renovations — and our clients tell us the difference is in the details: clear communication, transparent pricing, and trades who respect your home like it's theirs.

What we build

How it works

1. Initial call. Tell us what you're planning. We'll ask about your block (if new build), your home's age and construction (if reno), your budget range, and your timing. If we're a fit, we'll book a site visit.
2. Site visit + measure. Brad or our estimator visits your property, measures, photographs, checks services (sewer, power, easements for granny flats), and answers your questions face-to-face. No charge for the visit.
3. Detailed quote. Within 5-7 business days you'll receive a written quote: scope of works (trade-by-trade), inclusions, exclusions, allowances (if applicable), contract type (lump sum or HIA Renos), and payment schedule. If you've got plans, we quote to them. If you don't, we'll recommend a draftsperson or architect from our network.
4. Contract + deposit. You sign the contract (HIA or MBA standard form), pay the deposit (typically 5-10% for renos, 5% for new builds), and we lock in your start date. For jobs over $20k we use a standard NSW building contract; for smaller repairs we use a Scope of Works agreement.
5. Build phase. We manage every trade — carpenters, plumbers, electricians, concreters, renderers, painters. You deal with one point of contact (Brad or the site supervisor), not 15 subbies. Progress claims align with contract milestones. We send photos weekly if you're not on-site daily.
6. Practical completion + handover. Final walk-through, defects list (if any), trade certificates (electrical, plumbing, waterproofing), Occupation Certificate (if required), warranties, and your final invoice. You pay the balance; we hand over keys and Operation & Maintenance manuals.
