Investment Granny Flat Built Using The Trinity Plus Design
Building a granny flat in regional NSW is an increasingly popular way to generate rental income and make better use of existing land. For Brendan, the objective was simple — add a high-quality investment property to his Merriwa block while continuing to live in the main house.
Located in the Upper Hunter region of New South Wales, Merriwa offers generous block sizes and strong demand for rental accommodation, making it well suited to secondary dwellings. Brendan selected The Trinity Plus, a proven three-bedroom granny flat design that delivers practical family living and strong long-term investment value.
The project was completed in just 8.5 weeks, creating a modern and functional rental-ready home.
Why a 3 Bedroom Granny Flat Was the Right Choice
Rather than building a smaller secondary dwelling, Brendan chose a 3 bedroom granny flat to maximise rental appeal. In regional areas like Merriwa, larger layouts often attract families, workers, or shared living arrangements, improving flexibility and long-term occupancy.
By building on his existing property, Brendan was able to:
- Create an additional income stream
- Increase overall property value
- Make better use of available land
- Deliver a self-contained home suitable for long-term tenants
For many Upper Hunter property owners, this approach provides a practical alternative to purchasing a separate investment property.
The Trinity Plus — A Proven Three Bedroom Layout
Brendan selected The Trinity Plus, one of Aplus Granny Flats’ established three-bedroom designs. The layout is designed for comfortable everyday living while remaining efficient to build.
The design includes:
- Three full-sized bedrooms
- Open-plan kitchen, living, and dining area
- Functional bathroom layout
- Practical flow suited to family living
The “Plus” version of the design includes:
- A European-style laundry cupboard, improving internal space efficiency
- A slightly larger porch deck, enhancing outdoor usability and street presence
These refinements provide additional functionality without changing the core layout of the home.
Built for Durability and Efficient Construction
The granny flat was constructed using a slab-on-ground foundation with a steel frame and truss system, providing strength, durability, and long-term structural performance.
Standard inclusions were selected throughout, ensuring a cost-effective build while delivering a modern finish suitable for rental use. This approach kept construction efficient while maintaining quality and comfort for future tenants.
From commencement on 19 August 2024 to practical completion on 17 October 2024, the project was delivered in just 8.5 weeks.

Investing in Granny Flats in Merriwa and the Upper Hunter
Regional locations such as Merriwa are particularly well suited to granny flat investment due to:
- Larger residential blocks capable of accommodating secondary dwellings
- Consistent demand for rental housing
- Lower entry costs compared to metropolitan areas
- Strong appeal for families and workers in the Upper Hunter region
A well-designed three bedroom granny flat provides flexibility for tenants while creating stable long-term income potential for property owners.
A Practical Investment Outcome
Brendan’s Merriwa project demonstrates how selecting a proven design and focusing on efficient construction can deliver a straightforward investment outcome. The Trinity Plus design provided the space, functionality, and rental appeal needed while keeping the build process streamlined.
For property owners in Merriwa and across the Upper Hunter, building a 3 bedroom granny flat remains an effective way to unlock additional value from residential land while meeting local housing demand.
