Why Build a Duplex or Dual Occupancy Home?

A duplex or dual occupancy design offers many advantages, especially for homeowners in Sydney’s growing suburbs:

  • Two homes on one block – Ideal for multi-generational living or creating a steady rental income
  • Boost your property’s value – Increase capital growth and yield in high-demand locations
  • Live in one, rent the other – Offset your mortgage or plan for future income
  • Great alternative to subdividing – Make smart use of your land without selling it off
  • Customised to suit your block – Tailored designs for narrow, corner, or sloping blocks

Whether you’re a seasoned investor or building your first home, a duplex build is a clever, future-proof way to make the most of your land.

Duplex Home Builder Sydney – How Our Process Works

As a boutique duplex builder in Sydney, our process is collaborative, transparent, and tailored to your needs:

1. Initial Consultation & Feasibility

We start by understanding your vision, reviewing your block, and identifying what’s possible. If you don’t yet own land, we can help you find a block that’s suitable for a duplex or dual occupancy development.

No cookie-cutter designs here. We’ll work with you to create a custom duplex floor plan—whether that’s mirror-image layouts, side-by-side dwellings, or designs tailored to sloping sites.

3. Site Assessment & Council Approvals

Our team has deep knowledge of local council regulations across Sydney and the Illawarra, so we’ll manage planning requirements and guide you through the approval process with ease.

4. Fixed Price Quote & Build Timeline

We offer clear, upfront pricing and realistic timelines—no hidden surprises. Your quote includes everything from site costs to premium finishes, so you know exactly what to expect.

5. Quality Construction, End-To-End

You’ll work directly with Michael, the owner of Michelangelo Designer Homes, throughout your project. With meticulous attention to detail and a handpicked team of skilled trades, we deliver exceptional homes built to last.

Every block is different—and so is every family. That’s why we don’t just offer pre-designed floor plans. Instead, we collaborate with you to create a duplex or dual occupancy home that reflects your lifestyle, suits your land, and meets your financial goals.

Our duplex designs are ideal for:

  • Narrow blocks

Duplex FAQs

A duplex is a residential building that contains two separate dwellings under one roof, typically sharing a central wall. Each home has its own entrance, amenities, and outdoor space. Duplexes are ideal for families, investors, or anyone looking to maximise their land.

While the terms are often used interchangeably, dual occupancy can refer to any two dwellings on a single block—either attached (like a duplex) or detached (like a main home and a granny flat). A duplex is a specific type of attached dual occupancy.

This depends on your block size, frontage, slope, and local council regulations. Most Sydney councils have minimum requirements, and some blocks—especially corner lots or wide frontages—are ideal. We’ll conduct a site assessment to determine feasibility.

Costs can vary based on block conditions, design complexity, finishes, and council requirements. At Michaelangelo Designer Homes, we provide transparent, fixed-price quotes tailored to your block and goals.

Absolutely. Unlike volume builders, we offer fully customisable duplex designs, tailored to your land, lifestyle, and investment goals—whether you’re building for family or future rental income.

The process varies depending on approvals, site prep, and your design. On average, a duplex build in Sydney can take 9–12 months, from design through to completion.
