Maximise your property’s potential with a dual occupancy build by Phase Projects

If you’re a homeowner or investor in Sydney looking to make the most of your land, increase rental income, or create a flexible living arrangement for extended family, a custom duplex build could be the ideal solution. At Phase Projects, we specialise in crafting high-quality, tailored duplex homes designed to meet your needs, lifestyle, and long-term investment strategy.

The Benefits of Building a Duplex in Sydney

With increasing land values and a growing demand for more adaptable housing, duplex developments offer a smart and future-ready investment. Whether you’re planning to live in one side and lease the other or rent out both, the advantages are significant:

Dual Income Stream
Generate two separate rental returns from a single land title, significantly enhancing your return on investment.

Live and Lease
Enjoy your own private residence while generating consistent income from the second dwelling.

Multi-Generational Living Made Easy
Provide independent, nearby housing for aging parents, adult children, or extended family—all under one roofline.

Flexible Rental Options
Choose between long-term leasing or short-stay platforms like Airbnb to optimise your revenue.

Cost-Efficient Construction
Duplexes share infrastructure, making them more affordable to build than two separate homes—while still offering the feel and function of standalone dwellings.

What’s Changing in NSW Planning Laws—and Why It Matters

Recent changes to NSW’s low- and mid-rise housing policy aim to fast-track development approvals and deliver more diverse housing in well-located suburbs. These reforms are designed to simplify the process, reduce bottlenecks, and create greater certainty for builders and developers.

Minimum Lot Sizes Simplified

The new guidelines standardise the lot size and frontage requirements for different housing types:

• Dual Occupancy – Minimum 450m² lot size with at least 12m frontage
• Terrace Housing – Minimum 500m² with 18m frontage
• Multi-Dwelling Housing (e.g., Townhouses) – Minimum 600m² with 15m frontage
• Low-Rise Apartment Buildings – Minimum 500m² with 12m frontage (subject to zoning)

These clear benchmarks give you confidence in the development potential of your site—without second-guessing council interpretations.

Faster, Clearer Approval Process

If your proposed development meets the specified criteria, councils will be required to approve it—eliminating uncertainty and unnecessary delays. These changes are designed to cut red tape and accelerate the delivery of much-needed housing across NSW.

What This Means for You as a Developer or Homeowner

Whether you’re looking to unlock the value of your land or enter the property development space, these planning updates open the door to more opportunities. You’ll benefit from:

• Greater clarity on what you can build and where
• Shorter approval timelines
• Higher potential for long-term capital growth in well-connected areas

These reforms aim to encourage smart, sustainable growth by enabling more homes to be built in areas with existing infrastructure and transport links.
