Perth’s Dual Key Specialists

Dual Key Homes in Perth, Designed for Smarter Property Investment

Looking to maximise your investment property’s rental potential? A Dual Key home could be one of the smartest ways to grow your property portfolio.

At B1 Homes, we’ve been designing and building Dual Key homes for years, working alongside investors, buyer’s agents, finance professionals and property managers to create homes that are purpose-built for long-term investment performance.

Unlike many builders who simply adapt a standard home design, our Dual Key homes have been thoughtfully designed from the ground up to deliver practical layouts, greater tenant privacy and a streamlined ownership experience.

Whether you’re a first-time investor or expanding an existing portfolio, our team can help you find the right Dual Key home and land package across Perth and guide you through every step of the journey.

Why More Perth Investors Are Choosing Dual Key Homes

As Perth continues to experience strong population growth and demand for quality rental accommodation, many investors are looking for smarter ways to maximise the performance of their investment property.

A Dual Key home offers the opportunity to generate two rental incomes from a single property while only requiring one land purchase and one construction contract.

Potential benefits include:

• Opportunity to generate two rental incomes
• Improved cash flow potential
• Reduced vacancy risk through two independent tenancies
• One settlement and one construction process
• Broader tenant appeal
• Greater flexibility for future investment strategies
• Long-term wealth creation

Every investor’s circumstances are different, but for many, a Dual Key home provides an effective way to make their investment work harder.

Why Choose B1 Homes?

Not all Dual Key homes are created equal.

Anyone can build two residences under one roof.

Designing a Dual Key home that performs well for investors, appeals to quality tenants and makes life easier for property managers requires years of experience.

That’s exactly what sets B1 Homes apart.

We’ve continually refined our Dual Key range through feedback from:

• Experienced property investors
• Buyer’s agents
• Finance professionals
• Property managers
• Our own clients

This experience is reflected in the details that matter, including the incorporation of a firewall between the two dwellings, designed to help limit the spread of fire between residences and provide an added level of protection, while creating greater separation between each home.

Every improvement has been made with one objective in mind:

To create one of Perth’s most complete and investment-focused Dual Key home ranges.

Words from Director of Investor Growth, Janine.

“Working alongside B1 Homes over the years, particularly within the dual key space, has been an absolute pleasure.

What sets B1 Homes apart is their clear focus on investment outcomes. They are not simply building dual key homes, they are developing well-considered investment assets with long-term performance in mind.

From our perspective as dual key specialists at Ray White Northern Coast, we see firsthand what drives strong returns and where challenges can arise in the management of dual key properties. B1 Homes are consistently open to this insight and actively incorporate practical feedback into their designs.

It has been a genuine pleasure working alongside their team and clients from the early design stages, ensuring each project is positioned to achieve the best possible outcome for the investor within its specific market.

This collaborative approach ensures their homes are not only functional and well thought out, but also positioned to perform strongly in the rental market over time. The result is a smarter investment, one that delivers consistency, efficiency, and long-term value for the investor.

B1 Homes are setting a benchmark in the dual key space by aligning design with real-world investment strategy, not just construction.”

Why Investors Return to Build with B1 Homes

One of the strongest endorsements of our Dual Key homes comes from the investors who choose to build with us again.

Many of our clients have returned to build a second, and even third, Dual Key home after seeing the performance of their first investment.

That level of repeat business reflects the confidence investors have in both our product and our team.

We’re also proud to receive consistent feedback from property managers who tell us our homes require fewer defects at handover than many comparable Dual Key builds they’ve inspected.

It’s another example of the attention to detail we bring to every home we build.
