Duplexes & Dual Occupancies vs Townhouses & Granny Flats

What are the Best Building Solutions for You?

When it comes to building multiple residences on the same block, there are a few different options. What is the difference between them all and what are the best building solutions for you?

  • Duplexes and townhouses are ideal for generating a second property income.
  • Granny flats and dual occupancy homes are well suited if you need a second dwelling for a family member to live with or next to you.

Did you know that the NSW government is fast-tracking approvals for duplexes, dual occupancies, and townhouses? As per The Low Rise Housing Diversity Code, approval can be issued in as little as 20 days (once lodged with all required reports).

Design Considerations (So You Don’t Hit Roadblocks)

Parking Compliance
Most duplex builds require two car spaces (one per dwelling, often one in the garage and one in the driveway). Getting this right avoids costly redesigns.
Privacy & Setbacks
Smart placement of windows, screens, and alfresco areas protects neighbour amenity and ensures approvals go smoothly.
Efficient Layouts
On narrow Inner West blocks, party wall and stair positioning maximise space and simplify construction.
Acoustic & Fire Standards
Dividing walls must meet NCC requirements for fire safety and noise, with careful detailing at slabs and roofs.
Light & Ventilation
North facing living, cross-breezes, and shading improve comfort and reduce energy costs.

FAQs on Building a Double Storey Duplex

How much does a two-storey duplex cost in Sydney?

Costs depend on site access, slope, demolition, services upgrades, façade complexity, structure, finishes, and whether you’re doing Torrens subdivision. We start with a feasibility check, then give you a concept + price guide so you’re not guessing.

What lot size and frontage do I need?

Rules vary by LGA and zoning. Many councils look for compliant frontage, private open space, and parking that fits the street. Frontage requirements often sit around the 14 meters subject to location, but we confirm against your council’s DCP so you don’t design something that can’t be approved.

DA vs CDC: which is faster for a duplex?

Complying Development (CDC) can be faster if your site ticks all the boxes. If it doesn’t, a Development Application (DA) is the path. We assess both routes up-front and advise on timeframes and risks.

How long from first chat to keys?

Every project is different, but most follow a similar timeline:

  • Pre-construction (design, approvals, feasibility): around 4–8 months
  • Construction: usually 8–12 months

Timeframes can vary depending on approvals, selections, weather, and site conditions. We’ll keep you informed along the way, so you always know what stage your project is at.

Torrens title or strata title, what's better?

Torrens can improve resale in many suburbs because each dwelling has its own land title. Strata can lower some upfront costs but adds shared areas and ongoing admin. We’ll map the numbers and the approval implications for your address.

Can you do a duplex on a narrow or sloping block?

Yes, on narrow blocks we design efficient layouts with smart stair and party-wall placement to maximise space. On sloping sites, we use split levels and stepped slabs to make the most of your land.

Do I need separate meters and services?

Yes. Each dwelling should have its own electricity, water, gas (if used), and NBN connection. This is especially important for Torrens title duplexes. We plan meter locations and service runs early in the design stage to avoid surprises later.

What parking do I need for approval?

Most councils require at least one compliant off-street space per dwelling, usually a garage. Corner blocks or driveways near intersections may have extra rules. We design with parking compliance in mind to ensure your duplex passes approval.

What’s the difference between dual occupancy and a duplex?

“Dual occupancy” is the planning term for two dwellings on one lot. A “duplex” is one common form of dual occupancy: two attached homes with a shared dividing wall.

Can I live in one and rent the other?

Yes. Many duplex owners choose this approach. We can customise the design for easier management and stronger rental appeal, with features like extra storage, acoustic upgrades, and durable finishes. Many Clover Homes clients also choose to up-spec the side they live in while keeping the other practical for tenants. For rental yields and tax benefits, it’s best to speak with your financial adviser.

Can I knock down and rebuild a duplex?

Absolutely. Clover Homes can manage the entire process including demolition approvals (if we complete the demolition), temporary services, fencing, full design, and council/CDC approvals right through to construction. This way your duplex project starts smoothly and is built seamlessly from beginning to end.

Will a corner block help?

Often, yes. You can give each dwelling its own street address and façade, which helps privacy and resale. Corner blocks can also simplify parking and access.

How many bedrooms and bathrooms work best?

In Sydney’s family suburbs, 3-4 bedrooms with 2.5 bathrooms is the sweet spot. If the block and market suit, a second living space or study near the entry boosts appeal.

How do you manage noise between dwellings?

Our dividing walls and floors are designed to meet the National Construction Code (NCC) acoustic standards. This is achieved using approved systems such as full brick or lightweight fire- and sound-rated construction. We pay close attention to junctions at slabs, ceilings, and rooflines, and confirm details on site to ensure lasting noise and fire separation.

What energy and sustainability features are standard?

We consider orientation, shading, insulation, glazing, ventilation paths, and roof space for solar. BASIX compliance is managed with your plans so you meet targets without over-spending.

Do you build from my architect’s plans?

Yes. We can price and build from your approved plans or start fresh with our design team. Either way, we’ll make sure documentation is build-ready.

What approvals and certificates do you handle?

We manage the full approval process including DA or CDC, BASIX, engineering, certifier coordination, inspections, and the relevant certificates. You deal with one team from start to finish. If you’re subdividing, we’ll also connect you with the right professionals to guide you through that process.

What warranties apply?

All Clover Homes projects are covered by NSW statutory warranties. Major defects are protected for a longer period than minor defects, giving you peace of mind. In addition, manufacturer warranties apply to many fixtures and products used in your home.

Can I stage construction finish one side first?

A duplex is usually built together for efficiency and certification. If staging makes sense for your program, we’ll advise what’s practical and what approvals require.

What’s the next step to check my site?

Contact Clover Homes and we’ll run the planning checks, identify any risks, and provide layout options with a price guide so you can decide with confidence.
