It was built to your own plans
Custom-built homes
A one-off design is rebuilt to its own plans, not a builder’s standard rate. Insure it for what that rebuild would cost, architect and engineer included.
High-value home insurance is home and contents cover for a house that costs more to rebuild than most policies are built for. Past a few million, fewer insurers will take it, and some send it to an underwriter. Gary puts it to every one that can.

Every insurer sets a ceiling on the building it will cover online. We measured ours by asking at rising figures, or read them from the insurer’s own rules. By the rebuild cost of the house, here’s who on our panel can take it:
Building sums insured. One mainstream insurer’s limit is $5 million for building and contents together, with contents up to $500,000. Limits move; the quote always says why an insurer didn’t price.
In November 2026 we priced one house through our form: two storeys, a pool, top-of-the-range fittings and $250,000 of contents. In Melbourne, taking the building from $2 million to $2.9 million raised the price by only 24% to 31%.
The same house at $2.5 million cost at least 76% more in Sydney, partly because New South Wales charges an emergency services levy on the premium. The full story and figures. At $8 million, the mainstream insurers declined on their limits, and the specialist’s underwriters were the route to a price.
The premium follows the rebuild figure, so getting that figure right matters more than anything else on the form. Our home insurance page has the spread across ordinary homes too.
Building sum insured. Annual prices from the two mainstream insurers that priced it, including GST, stamp duty and the NSW levy, before our broker fee. Test quotes through our own form; insurers unnamed because the panel changes.
Each card names the part of the policy that responds, from three home wordings on our panel. Every quote links its own PDS.

Custom-built homes
A one-off design is rebuilt to its own plans, not a builder’s standard rate. Insure it for what that rebuild would cost, architect and engineer included.

Heritage homes
One insurer on our panel doesn’t write heritage-listed homes. The wordings we read pay for matching materials only up to a limit, so original detail belongs in the sum insured.

Grounds and outbuildings
Pools, tennis courts, fences, paved driveways and landscaping count as part of the home in the wordings we read, so they belong in the rebuild figure. Some carry fixed limits.

Art and valuables
Unlisted jewellery is limited to $5,000 or $10,000 an item in the wordings we read. Listing a piece, with a valuation, is how it’s insured for what it’s worth.

Waterfront homes
Storm and flood are defined separately, and each insurer prices the address. The quote shows which ones take it and what each PDS says.

Building work
Large works change the cover. The wordings we read need telling before work over $75,000 or $150,000, and one excludes work on the roof, outside walls or structure.
The building sum insured is what it would cost to clear the site and build the same house again, with the same finishes, fees and today’s building rules. The land isn’t in it.
Enter the address and we show a rebuild range from public records under the building question. It works from floor area and a standard rate, so it can’t see imported stone, custom joinery or a hard site. For a house like that, a quantity surveyor’s figure is the one commonly relied on.
Start with the address. We look the property up, you check it, and the form goes to every insurer on our panel whose limits reach. Rent it out? That’s landlord insurance, in the same form.
For one two-storey house with a pool and $250,000 of contents, our panel returned $5,662 to $9,456 a year in Melbourne for building sums of $2 million to $2.9 million, in November 2026. The same house at $2.5 million cost $11,761 to $12,021 in Sydney, where an emergency services levy is charged on the premium. Prices include GST and stamp duty, before our broker fee.
There’s no fixed line, but cover starts to change from about $3 million to rebuild. That’s where the specialist on our panel starts quoting, and from $5 million most mainstream policies stop. A house with original heritage detail, architect finishes or a lot of art can need specialist attention at a lower figure.
It’s the same kind of policy, home and contents, with higher limits and more room for what a big or unusual house needs: a larger rebuild figure, listed valuables, outbuildings and grounds. Insurers call it luxury, prestige, high-value or high-net-worth cover. They mean much the same thing.
On our panel, one mainstream insurer prices a building up to $7 million online, and the high-value specialist takes homes from $3 million, through its underwriters. Above $7 million, the specialist is the one that quotes, and its underwriters decide each home on its own.
The specialist on our panel sends every home to its underwriters rather than pricing it automatically. A broker follows it up and brings you their terms. The mainstream insurers quote beside it where their limits reach, so you may see prices and a referral together.
Yes. The difference is the rebuild figure: a one-off design is rebuilt to its own plans, often with a longer build and higher fees. A public-record estimate works from floor area and a standard rate, so for a custom home a quantity surveyor’s figure is commonly relied on.
Everything here is general information only. It doesn’t consider your objectives, financial situation or needs. We explain how high-value home insurance works and show the prices insurers return; read the PDS and decide what fits.
