What Counts as a High-Net-Worth Home in 2025? The Complete Guide for Australian Prestige Homeowners

In 2025, more Australian homeowners than ever before are discovering that their property no longer fits within the limits of standard home insurance.Rising rebuild costs, architectural complexity, labour shortages and escalating coastal risks have pushed many luxury properties into a new category:

High-Net-Worth Homes.

But what actually qualifies a home as “high-net-worth”?And why does it matter for insurance?

Most homeowners have never been given a clear definition — and as a result, thousands are unknowingly underinsured.

This guide explains exactly what counts as a high-net-worth home in 2025, and why these properties require specialist insurance to be properly protected.

1. A High-Net-Worth Home Is Defined by Its Rebuild Cost, Not Its Market Value

This is the most misunderstood concept.

Your home’s market value is irrelevant to insurers.What matters is the true cost to rebuild it today — using the same materials, design and workmanship.

In 2025, homes with a rebuild cost above $2M–$3M are considered high-net-worth because:

• specialist trades are required

• custom materials must be sourced

• architectural structures must be replicated

• engineering standards have increased

• imported components have become more expensive

  
  

Most prestige homes in Australia easily exceed these thresholds.

2. Architectural Homes Automatically Qualify as High-Net-Worth

If a home includes any of the following, it is not considered “standard construction”:

• Architectural concrete

• Custom steelwork

• Large-span glazing

• Curved or oversized windows

• Bespoke timber joinery

• Custom-built kitchens

• Designer bathrooms

• Wine rooms, saunas, wellness spaces

• Grand outdoor entertaining areas

Replicating this craftsmanship is extremely expensive, making specialist insurance essential.

3. Homes with Imported or Premium Materials

Homes featuring:

• Italian stone

• German appliances

• European timber

• Marine-grade steel

• Custom glass systems

• Handcrafted fittings

…all fall into the high-net-worth category.

Why? Because replacing these materials in 2025 often costs double or triple the original price.

4. Coastal, Clifftop and Waterfront Homes Are Automatically Higher-Risk

Prestige coastal homes face:

• Salt corrosion

• Wind exposure

• Moisture damage

• Storm surges

• Structural stress on steep blocks

These homes require:

• Marine-grade replacements

• Specialist engineers

• Custom foundations

• High-strength glazing

This pushes the rebuild cost far beyond standard insurer limits.

5. Homes Containing High-Value Contents or Collections

You qualify as high-net-worth if your contents include:

• Art

• Watches

• Jewellery

• Antiques

• Designer furniture

• Rare collectibles

• Custom interiors

Standard insurance usually caps these at a few thousand dollars — far below their true value.

6. Homes Over 400–600 sqm Are Usually High-Net-Worth by Default

Large prestige homes require:

• Higher structural engineering

• Larger appliance sets

• More materials

• More labour

• Larger glazing systems

• More complex plumbing and electrical

  
  

The rebuild cost alone pushes these into high-net-worth territory.

Why High-Net-Worth Homes Need Specialist Insurance in 2025

Here’s the truth:

Retail home insurance cannot protect a luxury home.Its limits, wordings and claims processes are built for standard properties.

Specialist luxury home insurance offers:

✔ Accurate, professional rebuild valuations

✔ Broader cover for art, jewellery and collectibles

✔ Proper cover for coastal and architectural homes

✔ Higher policy limits

✔ A claims process built for complex, high-value properties

✔ Worldwide cover for valuables

✔ Replacement using original-standard materials

Without specialist insurance, a prestige home may be millions of dollars underinsured.

The Bottom Line

If your home is architectural, high-value, coastal, custom-built or contains luxury contents — it is a high-net-worth home.And in 2025, that means standard insurance is no longer enough.

Your home deserves protection that matches its true value, complexity and craftsmanship.

Prestige homes demand prestige insurance.
