One builder,
A custom home is a once-or-twice-in-a-lifetime decision. We treat it like it.
We don't do project homes. We don't do volume. We build maybe six to eight custom homes a year, and every one of them gets the same scrutiny, the same trades, the same project manager from first site visit to handover key.
That focus shows up in the finish. Joinery that closes silently. Render that's still crisp ten years later. Plumbing routed where it should be, not where it was easiest. Details most builders skip because nobody would notice — except the people who live there for the next thirty years.
Our Premium Services.
Architect-designed, tailored to you.
Work with your architect or use ours. The home is designed for your block, your aspect, your lifestyle — not lifted from a project home catalogue.
Custom builds, not volume work.
Six to eight homes a year, deliberately. Every build gets the same focused attention, same trades, same project manager from foundation to handover.
Approvals handled end-to-end.
DA, CDC, structural, hydraulic, BASIX, energy. We coordinate every consultant and every council interaction as part of the build scope.
Clean handover, maintenance included.
Maintenance period included as standard. Defects walked before handover, not after. The home is ready to live in from day one.

Why custom build clients choose us
A custom home is a once-or-twice-in-a-lifetime project. We treat it like one.
Custom new build clients want a builder who'll be honest about what their brief actually costs, who'll engage early enough to flag buildability issues before drawings are locked, and who'll deliver the home on the date and budget agreed at contract signing. That's a small builder market in Sydney — most volume builders can't deliver custom work properly, and most custom builders can't manage program. We sit in between.
We're Class 2 Licensed, structurally qualified to handle multi-storey residential without subcontracting it out. We've built homes across Vaucluse, Bellevue Hill, Mosman, Manly, Bondi and the Northern Beaches. The clients who hire us tend to be ones who've talked to three or four builders before finding us — they know what they want and want someone who can actually deliver it.
Sydney's Custom New Home Builders
Platinum Corp Construction builds custom new homes across Sydney's premium suburbs — the Eastern Suburbs (Bondi, Bellevue Hill, Double Bay, Vaucluse, Rose Bay), the North Shore (Mosman, Neutral Bay, Cremorne), and the Northern Beaches (Manly, Balgowlah, Freshwater). Every custom new build is delivered under a fixed-price contract by one Class 2 Licensed builder, with structural engineering coordinated in-house and no subcontracted layers between you and the people building your home.
A custom new home in Sydney is a 12-to-18-month commitment. Six to eight is all we build per year, deliberately. Every one of them gets the same focused attention, the same trades, the same project manager from first site visit through to handover. We don't do project homes. We don't do volume. We build a small number of custom homes very well.
Full Custom New Build Service
Our custom new home build service covers design coordination (with your architect or ours), DA or CDC approvals, structural engineering, BASIX and energy ratings, demolition where required, foundations and footings, framing and roofing, services rough-in, internal fitout, joinery and stone, finishes, landscaping integration, and final handover with a maintenance period included as standard.
Working With Architects on Custom Builds
Most of our custom new builds in Sydney are architect-designed. We work with most established Sydney residential architects — and prefer to come on early, during design development or construction documentation, so we can flag buildability or cost issues while there's still time to adjust the drawings. If you don't have an architect, we can recommend trusted partners we've worked with across the Eastern Suburbs, North Shore and Northern Beaches.
DA Approvals and Engineering Coordination
Every custom new build runs through a coordinated approvals package — DA or CDC submission, structural engineering, hydraulic engineering, BASIX, energy rating, sometimes bushfire or coastal hazard assessments depending on the site. We coordinate every consultant, every council interaction, every certifier touchpoint as part of the build scope. You sign documents — that's the extent of your involvement on the approval side.
Custom New Build Pricing in Sydney
Custom new home builds with us in Sydney typically start around $1.5M for a standard four-bedroom two-storey home with quality (not premium) finishes. Larger homes, premium specifications, complex sites (sloping blocks, coastal corrosion, heritage neighbours, view-line considerations), or fully bespoke joinery scale from there. High-end custom builds in Vaucluse, Mosman or Bellevue Hill commonly run $3M–$8M+. Every quote is fixed-price and line-itemised.
Knock Down Rebuild and Sloping Block Specialists
A meaningful portion of our custom new build work is knock-down-rebuild on existing sites — the land is the valuable asset, the existing home is uneconomical to renovate, the smartest move is demolition and a custom new build. We also handle sloping blocks well, which most volume builders don't — split-level designs, retaining walls, pier foundations.
Book a Custom Build Consultation
Custom new builds start with a site consultation. We walk the block with you, review the brief, talk through approvals and timeline, and follow up with a feasibility plan and indicative budget within two weeks.
