For Lachlan, the goal was clear — build a granny flat that could generate immediate rental income in one of the Central Coast’s strongest investment pockets.
Located in Woy Woy, this project takes advantage of the suburb’s position on the Sydney commuter belt, where demand for affordable, self-contained housing remains consistently strong. By selecting a proven design and keeping the build straightforward, Lachlan was able to move from construction to income very quickly.
The result is a two bedroom granny flat that has since been rented for $500 per week.
Woy Woy continues to attract both tenants and investors due to:
For property owners, this creates an opportunity to build a granny flat that can deliver reliable weekly returns while adding long-term value to the property.
Lachlan selected The Dock, a well-established granny flat design known for its practical layout and strong rental appeal.
The design includes:
Built using a slab-on-ground foundation with a steel frame and truss system, (steel is included as a free upgrade for all our Granny Flats) the home provides a durable and low-maintenance outcome — ideal for investment use.
Within the initial quote, Lachlan included a number of practical additions to enhance usability and tenant appeal:
These inclusions improve the overall liveability of the granny flat without overcomplicating the build.
Rather than adding further upgrades during colour selections, Lachlan chose to proceed with standard inclusions throughout. This helped keep the process efficient and cost-effective while still delivering a modern, comfortable home.
Approved under a Complying Development Certificate (CDC), the project benefited from a faster approval pathway, allowing construction to commence sooner and move quickly through to completion.
With construction complete, the granny flat was quickly tenanted, achieving a rental return of $500 per week. This outcome highlights the advantage of:
Lachlan’s Woy Woy project is a strong example of how a well-planned granny flat can transition quickly from construction to income.
By combining a proven design, practical inclusions, and a high-demand location, the result is a low-maintenance investment generating immediate return — exactly what many Central Coast property owners are aiming to achieve.
