Unlock Your Property’s Full Potential with a Custom Dual Occupancy Build by Phase Projects
If you are a homeowner or property investor in Sydney seeking to maximise the potential of your land, boost your rental income, or create a versatile living arrangement for family members, a bespoke duplex build could be the perfect answer. At Phase Projects, we specialise in creating high-quality, custom-designed duplex homes tailored to fulfil your specific needs, lifestyle preferences, and long-term investment strategies.

Explore the Advantages of Building a Duplex in Sydney
With the ever-increasing land values and a rising demand for more adaptable housing options, duplex developments represent a smart, forward-thinking investment choice. Whether you choose to reside in one unit while leasing the other or decide to rent both units, the benefits are substantial:
Dual Income Stream
Generate two independent rental returns from a single land title, significantly amplifying your return on investment.
Live and Lease
Relish your own private residence while simultaneously earning a steady income from the adjoining dwelling.
Facilitating Multi-Generational Living
Offer independent yet nearby housing for elder parents, adult children, or extended family—all within the same property footprint.
Flexible Rental Strategies
Opt for either long-term leasing or short-stay rental platforms such as Airbnb to maximise your revenue potential.
Cost-Effective Construction
Duplexes share essential infrastructure, making them more economical to construct than building two separate homes—while still providing the comfort and functionality of standalone residences.

What Changes are Occurring in NSW Planning Laws—and Why Should You Care?
Recent modifications to the NSW low- and mid-rise housing policies are designed to expedite development approvals and promote a wider variety of housing options in well-situated suburbs. These reforms aim to streamline the process, reduce bottlenecks, and provide more certainty for builders and developers alike.
Standardised Minimum Lot Sizes
The new guidelines establish clear, standardised requirements for lot sizes and frontages across various housing types:
- Dual Occupancy – Minimum of 450m² lot size with a minimum 12m frontage
- Terrace Housing – Minimum of 500m² with an 18m frontage
- Multi-Dwelling Housing (e.g., Townhouses) – Minimum of 600m² with a 15m frontage
- Low-Rise Apartment Buildings – Minimum of 500m² with a 12m frontage (subject to zoning)
These straightforward benchmarks provide you with confidence regarding the development potential of your site, eliminating doubts about council interpretations.
Accelerated and Clear Approval Process
Provided your proposed development meets the established criteria, councils will be mandated to approve it, removing uncertainty and unnecessary delays. These changes are intended to cut through red tape and hasten the delivery of much-needed housing throughout NSW.
What Implications Do These Changes Have for You as a Developer or Homeowner?
If you’re aiming to unlock the value of your land or step into the property development arena, these planning updates pave the way for new opportunities. You’ll gain:
- Enhanced clarity on what you can build and where
- Reduced approval timelines
- Increased potential for long-term capital appreciation in well-connected regions
These reforms are designed to foster smart, sustainable growth by facilitating the construction of more homes in areas that already feature established infrastructure and transport links.

I appreciate the insights on the potential benefits of a custom dual occupancy build. It’s fascinating how the housing market in Sydney has evolved, with land values soaring and flexible living arrangements becoming increasingly sought after. As someone who has been closely following trends in urban development, I can definitely see the appeal of duplex builds, especially for families looking to accommodate multi-generational living while also securing an additional income stream.
I really appreciate the insights in this post about dual occupancy builds! It’s fascinating how much potential Sydney properties hold, especially in a market like this. The idea of generating dual income streams really resonates with me. I have friends who went through a similar process and they not only increased their rental income but also created a space for their aging parents to live independently.
It’s interesting to consider how a dual occupancy build not only maximizes land use but also addresses the growing need for affordable housing in Sydney. With many families finding it increasingly difficult to afford standalone homes, duplexes present a viable solution that can enhance community living.
The idea of a custom dual occupancy build is really compelling, especially as Sydney’s housing landscape evolves. I’ve seen firsthand how families can benefit from such arrangements—not just in financial terms, but also in fostering community and support. For instance, my neighbor built a duplex that allowed them to have their parents live close by while still maintaining independence.
It’s fascinating to see how duplex builds, like the ones offered by Phase Projects, are emerging as a strategic choice for property owners in Sydney. Your emphasis on bespoke designs is particularly resonant, as it highlights the necessity of tailoring living spaces to both current needs and future aspirations.
