Duplex Vs. Townhouse
What Is A Duplex?
A duplex is a residential building divided into two separate units, either side-by-side or stacked vertically. Each unit typically has its entrance, amenities, and sometimes even separate utility connections. Duplexes are often owned entirely by one individual, who may choose to live in one unit and rent out the other, or rent both units for income.
What Is A Townhouse?
A townhouse is a multi-level home that shares one or two walls with adjacent properties but has its entrance. It is usually part of a larger complex or community and is individually owned. Townhouses often have shared amenities like pools, gyms, and landscaped gardens maintained by a homeowners’ association (HOA) or body corporate.
Comparing Ownership And Management
Duplex Ownership
A duplex generally sits on a single land title. The owner is responsible for the entire structure, including the surrounding land. This gives more freedom to manage or modify the property as needed, subject to local council regulations.
Townhouse Ownership
In contrast, a townhouse is often held under a strata title, meaning the owner is responsible for the interior, while the body corporate handles maintenance of shared spaces, exteriors, and community amenities.
Privacy And Independence
Duplex Living
Duplexes provide more privacy, particularly when designed with side-by-side layouts. With only one shared wall and often private backyards or driveways, residents can enjoy a level of seclusion closer to a standalone house.
Townhouse Living
Townhouses usually have neighbours on both sides (except for end units), making noise transmission and reduced privacy more common. Communal areas like driveways or gardens can also impact the feeling of independence.
Financial Considerations
Initial Cost
- Duplex: Typically has a higher purchase price due to its size and dual occupancy nature. However, the potential to generate rental income from one or both units can make it financially appealing.
- Townhouse: Generally more affordable upfront, especially appealing for first-home buyers or investors entering the market.
Ongoing Costs
- Duplex: As the owner, you’ll cover all upkeep and insurance costs. There are no body corporate fees, which means long-term expenses may be lower if well-maintained.
- Townhouse: Body corporate fees are standard and vary significantly depending on the amenities. These fees cover exterior maintenance, insurance, and shared facilities, but add to the regular outgoings.
Rental Potential
Duplex
Duplexes offer strong rental opportunities. Owners can live in one unit, rent out the other, or lease both to maximise income. This flexibility makes duplexes attractive for investors and owner-occupiers looking for extra cash flow.
Townhouse
While townhouses can also be rented out, their rental yield may be lower than that of duplexes, especially when factoring in body corporate fees. Some communities also impose restrictions on short-term leasing.
Flexibility And Control
Duplex Ownership Benefits
Duplex owners can renovate, extend, or redesign interiors and exteriors. If council approvals are in place, other owners or corporate bodies can make changes without consent.
Townhouse Limitations
Townhouse owners are often subject to strict rules enforced by the body corporate. These may cover pet ownership, changes to the façade, use of common areas, and even external paint colours. For those who value autonomy, these restrictions can be a deal-breaker.
Suitability For Different Buyers
First-Home Buyers
Townhouses are ideal for those looking to enter the property market without the hefty price tag. Their compact design, shared maintenance responsibilities, and central locations make them highly suitable for young couples or singles.
Families
Duplexes provide more space, a yard, and a traditional home layout, making them better suited to growing families. They often come with multiple bedrooms, garages, and more living area, contributing to a higher quality of family life.
Investors
From a rental yield perspective, duplexes tend to offer better returns. With two potential income streams, the ability to positively gear the property is higher. While often cheaper to buy, townhouses might be subject to more leasing restrictions and higher upkeep through levies.
Location And Lifestyle
Suburban Settings
Duplexes are commonly found in suburban or fringe areas. They offer larger plots of land and a quieter environment, which is great for those who prefer a slower pace or need more room for children and pets.
Urban Centres
Townhouses are more prevalent in inner-city or high-density areas, appealing to professionals or students who prioritise location and proximity to amenities like schools, shops, and public transport.

Frequently Asked Questions
Is A Duplex A Better Investment Than A Townhouse?
A duplex often provides a higher rental yield since it contains two separate dwellings that can be leased individually. This can generate dual income streams, making it appealing for investors. However, it also comes with higher upfront costs and more management responsibilities than a townhouse.
Are There Restrictions On What I Can Do With A Townhouse?
Yes, townhouse owners typically must follow rules set by a body corporate or homeowners’ association. These may limit exterior modifications, pet ownership, or rental terms. It’s important to review the strata bylaws before purchasing to ensure they align with your lifestyle and goals.
Which Option Is More Suitable For Families?
A duplex is generally more family-friendly due to its larger living space, private yards, and quieter suburban settings. Townhouses may feel more compact and are often better suited to singles or couples prioritising location and low-maintenance living.
