New homes, renovations and extensions across Sydney's Hills District and surrounds. We bring transparency, fixed pricing and a quality finish to every project.
We started GroundUp Builders in 2009 with one belief: that residential construction should be straightforward, properly priced, and done to a standard the owner can actually be proud of. Every project gets our principal builder on site — not a rotating crew of subcontractors you've never met.
From first site consultation to handover, we keep you informed at every stage. No surprises. No variation padding. Just quality work delivered on schedule.
From vacant block to finished home, or breathing new life into an existing property — we have the crew, the licence and the track record.
Typical build durations are listed on each service — so you can plan your life around the project, not the other way around.
Knockdown rebuilds, sloping blocks, split-level homes and dual-occupancy. We work with your architect or can recommend one — and we lock in a fixed price before a single slab is poured.
Whole-house transformations including structural changes, kitchen and bathroom upgrades, new flooring, re-roofing and everything between. One builder, one contract, one point of contact.
Ground floor additions, second storey additions, granny flats and detached studios. We handle DA and CC applications in-house with our certifier — no project management headaches for you.
Real projects, real results. Browse by category to see what's possible — every photo comes from a GroundUp site.
Framers, roofers, painters and other specialist trades — if you want to win more direct client work but don't hold a builder's licence, partner with GroundUp. We supply the licence, the contracts and the site supervision. You deliver your trade.
Most building disasters come down to the same handful of problems — unlicensed work, vague contracts, builders who disappear after signing. Here's how we handle each one.
Book a Free ConsultationNo obligation. We'll walk the site with you, talk through your goals and give you a realistic budget range — before you spend a cent.
NSW law requires a licensed builder for all residential work over $5,000. Lic. No. 298461C is visible on every contract, every sign and every invoice. You can verify it instantly at Service NSW.
Our quotes are detailed line-by-line specifications. If we miss something in the quote that was foreseeable, we wear it. Variations only arise from genuine owner-directed scope changes, not from our estimating gaps.
Home Building Compensation Fund cover is mandatory on contracts over $20,000 and gives you six years of structural defect cover and two years on non-structural work. We sort it before we break ground — always.
We provide a week-by-week programme before we start. Major milestones are documented. You receive a fortnightly progress update — not because you asked for it, but because we build it into every contract.
We're a mid-sized builder intentionally. Our principal is on your site daily during framing and critical stages. You won't deal with a project manager who calls your builder for answers — they're the same person.
Every image in our gallery is a GroundUp job. You can ask for the street address. We have clients who've agreed to host a site walk-through for serious prospects. Nothing sells quality like the real thing.
