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.
