Two-Bed Granny Flat in Charlestown: A Smart Rental Investment for Carolyn & Brendan

When Carolyn and Brendan decided to add a granny flat to their property in Charlestown, they were looking for a solid, long-term rental investment. They chose the Pavilion (modified) design from Aplus — a two-bedroom layout that fits well on a variety of lots and delivers comfortable living space for tenants. With the structure built under a Complying Development Certificate (CDC), the process was efficient, compliant, and aligned with their investment objectives.


Meeting Site Challenges: BAL 29 and Sloping Terrain

Their Charlestown block came with a couple of distinctive challenges. Firstly, the property was rated BAL 29, requiring careful attention to fire safety and material selection. Secondly, the site had a sloping terrain, which meant standard building methods wouldn’t suffice. To address this, Aplus included brick piers and brickwork to the subfloor perimeter, ensuring a stable and fire-resistant base.

Because of the slope, the build also required scaffolding — a logistical step that Aplus managed efficiently, ensuring safety and building integrity throughout construction.


Inside: Upgrades for Tenant Appeal

While the base Pavilion design offers a functional and flexible two-bedroom layout, Carolyn and Brendan opted for several upgrades to maximise comfort and rental appeal:

  • A small kitchen island bench — a feature that improves usability and modernises the kitchen layout.
  • Upgraded vanity and recessed shaving cabinet in the bathroom — adding convenience and a clean built-in finish.
  • Enhanced insulation, improving energy efficiency and comfort for tenants.
  • Carpeting in the bedrooms — delivering a warmer, homely feel than standard floor coverings.
  • Microwave provision in the pantry — a small but handy upgrade that makes day-to-day living easier for renters.

These choices reflect a clear investment in quality and tenant comfort — and play an important role in attracting reliable, long-term renters.

Why The Pavilion is a Great Fit for Charlestown

Charlestown is a suburb with a diverse mix of families, professionals and downsizers. The rental market here appreciates well-designed, self-contained units offering comfort, convenience, and value. A two-bedroom granny flat like The Pavilion provides:

  • A compact but spacious living footprint ideal for singles, couples or small families

  • Affordable rental accommodation with modern finishes and fixtures

  • Flexibility for use as a rental, guest house, or home for extended family

  • Compliance with BAL requirements when built correctly — a must for bushfire-adjacent or hazard-zoned areas

For investors like Carolyn and Brendan, the modified Pavilion builds on this demand by offering a quality build tailored for comfort and longevity.


Strong Returns: Rental Income for Investors

Upon completion the flat was quickly tenanted, with a weekly rent of $550. For an investor, that represents a competitive return for a two-bedroom unit in Charlestown — especially given the added value of the upgrades and build quality.

The combination of a robust build (brick piers, proper fire-safe construction), thoughtful internal upgrades, and the inherent appeal of a modern two-bedroom layout helped the property stand out in the rental market.
