You’ve found the perfect property. It checks all the boxes, and now it’s time to bring it to life! Then your builder asks the question that sets everything else in motion: one level or two?
While it might sound like a simple design choice. In reality, the decision between single-storey vs double storey homes shapes almost every part of your build and even your lifestyle. It influences everything from the size of the home and how much it costs to build to your ongoing energy bills, how your family moves through the home each day, how much outdoor space you can keep, and even the future resale value of your property.
In Brisbane, this decision becomes even more important. Block shapes vary significantly from suburb to suburb, and the subtropical climate has strong opinions of its own when it comes to light, airflow, and liveability. What works beautifully on one site may not be the best fit for another.
In this guide, we’ll walk you through every factor that matters, from cost and lifestyle to block suitability and resale, so you can make the call between single storey vs double storey homes with a little more clarity.
Key Takeaways
- Single storey homes suit wider, flatter blocks and buyers who want accessibility, seamless indoor-outdoor flow, and simpler long-term maintenance.
- Double storey homes work brilliantly on narrow, sloping, or premium inner-city Brisbane blocks, offering more living space on a smaller footprint and clearer zoning between living and sleeping areas.
- Per square metre, double storey builds are typically more expensive, but a single storey of equal size often costs more overall because of the larger slab and roof.
- Your block (size, slope, orientation, and council setbacks) will often narrow the decision before lifestyle preference even enters the picture.
- There’s no universally ‘better’ choice. The right home design is the one that fits your land, your life stage, and your long-term plans.
Single Storey vs Double Storey Homes: An Overview
What is a single storey home?
A single storey home puts all your living space (bedrooms, living areas, kitchen, bathrooms) on one level. There are no internal stairs, and everything flows horizontally. Think of the classic Queenslander cottage, modern lowset family homes, and most acreage builds around Brisbane’s outer suburbs.
What is a double storey home?
A double storey (or two storey) home stacks your living space across two levels, usually with living, kitchen and dining downstairs, and bedrooms and bathrooms upstairs. It makes the most of vertical space, which matters when your block is narrow, sloped, or positioned for a view.
Here’s how the two designs compare across the factors that matter most:
| Factor | Single Storey | Double Storey |
| Best-suited block | Wider, flatter blocks | Narrow or sloping blocks |
| Upfront build cost | Often lower per sqm, larger slab | Higher per sqm, smaller footprint |
| Backyard space | Smaller (larger building footprint) | Larger (smaller building footprint) |
| Accessibility | Excellent, no stairs | Lower, stairs required |
| Privacy and zoning | All rooms on one level | Clear separation of living and sleeping |
| Views and airflow | Ground-level only | Elevated views, better cross-breezes |
| Resale appeal | Strong with families and downsizers | Strong in inner-city and premium markets |
| Build timeline | Typically faster | Longer due to staging and scaffolding |
Does Your Brisbane Block Dictate the Answer?
Before you fall in love with a particular home design, the land itself may do a lot of the decision-making for you. Block size, shape, slope, and orientation will often narrow your options long before personal preference can even be considered. In Brisbane, where no two suburbs feel quite the same, your block is usually the biggest influence on whether a single storey or double storey home makes the most sense.
Narrow blocks, wide blocks, and everything in between
If you’re building on a narrow inner-city block, typically under 10 metres wide, a double storey design is often the only way to get the living space a modern family needs without sacrificing every square metre of outdoor space. Many suburbs regularly produce narrow lots where going up makes more sense than going out.
On a wider block, you have the luxury of choice. A single storey home can sprawl comfortably, with bedrooms arranged along one wing and living areas along another. You may lose some backyard to the larger footprint, but the trade-off is often worth it for the flow and accessibility.
Sloping blocks and elevated sites
Brisbane is full of character blocks that slope. Suburbs like The Gap, Kenmore, Chapel Hill, Bardon, and pockets of Toowong or Holland Park will often deliver a block with 2 to 5 metres of fall across its length. These sites suit double storey (or split-level) designs beautifully. You can tuck a garage and lower living area into the slope, lift the main living zone for breeze and views, and make the most of the vertical space.
If you’re not sure how your slope should influence the design, our guide on lowset vs highset houses digs deeper into how elevation changes what’s possible.
Suburban lots vs inner-city infill
Out in the larger suburbs, block sizes allow either design to work. Here, your choice is usually driven by lifestyle and preference rather than physical constraint.
On an inner-city infill block, council setbacks, overshadowing rules, and boundary requirements can shrink your buildable area significantly. Always check Brisbane City Council’s residential design guidelines (or have your builder do it) before locking in a design direction!
1. Cost Comparison: What To Consider
When comparing single storey vs double storey homes, cost is usually one of the first considerations, but it’s also one of the easiest areas to misunderstand.
Upfront build costs
On a per-square-metre basis, double storey homes can often cost more to build than single storey homes of the same internal size. This is largely due to the additional structural requirements involved like engineered floor systems, structural steel, scaffolding, staged construction, and more complex waterproofing between levels.
That said, single storey homes aren’t automatically the “cheaper” option. While they may have a lower cost per square metre in many cases (depending on size, inclusions, finishes, and design complexity), they require a much larger slab and roof area to achieve the same internal footprint. That means more concrete, more roofing materials, and a larger structural base overall.
In reality, once you factor in the total footprint needed for a single level design, the price difference between the two often narrows more than expected.

Long-term maintenance and running costs
Beyond the initial build, the way your home is designed continues to impact your wallet over time.
Single storey homes are generally simpler to maintain. Roof access is easier, exterior painting is more straightforward, and tasks like gutter cleaning tend to be less complex and less costly. For many homeowners, this simplicity translates into lower ongoing maintenance expenses and fewer logistical headaches over the life of the home.
Double storey homes, however, require more intentional design to perform well in Brisbane’s subtropical climate. Upper levels can become uncomfortably warm without the right combination of insulation, cross-ventilation, and shading. Zoned air conditioning systems are often used to manage temperature differences between floors, but they can increase energy consumption if not designed efficiently.
The roof design you choose also plays a significant role in how well either design copes with the heat.

2. Space, Layout, and How You Actually Live
Cost aside, the way each design shapes your daily life is where the real decision often gets made.
Making the most of a single level
Single storey homes are all about ease and connection. With everything on one floor, the layout naturally encourages open, flowing spaces (kitchens that connect to living areas, living rooms that extend to alfresco zones, and outdoor spaces that feel like a true extension of the home.)
This design works especially well for families who want to stay connected throughout the day. You can be cooking, working, and relaxing in different parts of the home while still feeling part of the same space. It also removes everyday friction points. Grandparents, guests, or family members with mobility considerations can move comfortably through the home without limitations.
The trade-off is footprint. Because everything spreads out horizontally, single storey homes naturally take up more of your land. If a large backyard is a priority, your block size needs to support that.
Vertical zoning in a double storey
Double storey homes bring a completely different kind of liveability. Instead of everything existing on one level, spaces are intentionally divided. Downstairs typically becomes the social heart of the home; kitchen, dining, living areas, and often a study or media room. The upstairs becomes a quieter retreat, with bedrooms, bathrooms, and sometimes an additional lounge or parents’ space.
The ability to “switch off” a level of the home makes a noticeable difference in day-to-day comfort.
There’s also a major spatial advantage. Because the home builds upward instead of outward, you can achieve the same internal living area while preserving significantly more outdoor space. For many Brisbane homeowners, that means a bigger backyard, better entertaining areas, or simply more breathing room on the block.
3. Lifestyle Fit: Matching the Design to Your Family
The best home design is one that matches the way you live now, and the way you’re likely to live in 10 or even 20 years.
Young families
Families with small children often lean single storey for supervision and safety. No stairs means no gates, no tumbles, and no carrying a sleeping toddler up to bed at 7pm. Open-plan layouts also make it easier to keep an eye on what’s happening outside while you’re cooking or working inside.
That said, double storey homes are incredibly popular with Brisbane families too. The separation of spaces can actually make life feel more organised. Kids get their own upstairs zone, while downstairs stays more structured and presentable for guests, work, and the school morning rush.
Downsizers and retirees
If you’re building your forever home or preparing for a lower-maintenance life stage, single storey is usually the smarter call. Stairs become harder as we get older, and retrofitting accessibility into a two storey home can be complex. A well-designed single storey build can serve you beautifully into your 70s, 80s, and beyond.
4. Other Key Considerations
Privacy, Natural Light, and Brisbane’s Climate
Brisbane’s subtropical climate has a major influence on how comfortable your home feels year-round. Single storey homes naturally support indoor-outdoor living, with easy flow to alfresco areas, even natural light distribution, and no risk of overheated upstairs rooms in peak summer. They tend to feel breezy and connected to the outdoors, which suits Brisbane living well.
Double storey homes offer a different advantage, with elevated living spaces that capture breezes and upper-level views you can’t achieve on a single level. However, they need more intentional design; orientation, insulation, shading, and ventilation all play a bigger role in keeping the upstairs comfortable. When well-designed, they perform strongly in Brisbane’s climate, but they rely more heavily on smart planning.
Resale Value and Buyer Appeal Across Brisbane
Resale performance in Brisbane depends heavily on location. In inner-city and prestige suburbs like New Farm, Paddington, and Ascot, double storey homes often attract stronger demand, aligning with buyer expectations for architectural, multi-level living and view potential. These homes typically perform well when designed to suit the suburb and street context.
In family-oriented and outer-ring suburbs, single storey homes tend to appeal to a broader buyer pool, including young families and downsizers. They are consistently in demand due to their accessibility and practicality. Ultimately, resale strength comes down less to storeys and more to how well the design fits the block and the surrounding area.
Construction Timelines and Build Complexity
Single storey homes are generally faster to build, often taking around 5 to 7 months from slab to completion, depending on size, finishes, and weather. With fewer structural stages and simpler sequencing, they tend to move through construction more quickly and with fewer delays.
Double storey builds usually take longer, around 7 to 12 months, due to added structural work, scaffolding, and staged construction processes. They also require more coordination between trades and inspections. While this extends the timeline, it’s a predictable part of the build process rather than a drawback.
Future-Proofing: Can You Expand Later?
Single storey homes are often easier to extend outward, making them a flexible option if your land allows for future additions. Many homeowners choose to expand over time as family needs change, adding rooms or extra living areas at a later stage.
Adding a second storey to an existing home is possible but significantly more complex and costly, often involving structural upgrades and roof removal. If there’s any chance you may want a double storey in future, it’s more efficient to design for it from the outset so your foundations and structure can support it later.
Common Mistakes Brisbane Homeowners Make
After years of helping Brisbane homeowners navigate this decision, we’ve seen a few patterns repeat themselves, most of which come down to rushing the design decision or focusing on the wrong priorities too early.
- Ignoring block orientation: A north-facing living area is one of the most valuable design advantages you can have in Brisbane. It impacts light, comfort, and energy efficiency in both single and double storey homes, so it should be prioritised before locking in any floor plan.
- Over-prioritising aesthetics over practicality: It’s easy to fall in love with a beautiful design, but not every “dream home” suits every block. A floor plan that looks perfect on paper can quickly become frustrating to live in if it doesn’t respond to your site, lifestyle, or climate. In Brisbane especially, factors like orientation, airflow, yard space, and street context often matter far more than visual appeal alone.
- Forgetting about future life stages: The home that works for a young family today may not suit you in 10–20 years. Good design considers long-term needs, not just the current season of life.

Single Storey Vs Double Storey: Your Decision Checklist
Before you commit to single or double storey, run through these seven questions. If you can answer them confidently, you’re ready to talk to a builder.
- Is my block flat, narrow, or sloping, and how does that shape what’s buildable?
- Who will live in this home, and how might that change over the next 10 years?
- How much backyard space matters to my family?
- What’s my total build budget, including landscaping, driveway, and fit-out?
- Do I want to maximise views, cross-breezes, or privacy?
- Am I planning to stay long-term, or am I building with resale in mind?
- Have I spoken to a builder who understands my suburb and block type?
There’s No Wrong Choice, Only the Right One for You
Single storey vs double storey isn’t a debate with a universal winner. It’s a decision shaped by your block, your budget, your family, and the life you’re designing a home around.
What matters is that the design fits. A beautifully crafted single storey home on the right block will serve a family for generations. A well-designed double storey on a narrow or sloping site can deliver a lifestyle that no lowset home could match. The wrong design on either block will always feel a step off, no matter how expensive the finishes.
If you’re ready to stop weighing up and start building, talk to the team at Urban Luxe Projects. We’ll look at your block, listen to how you want to live, and help you design a home that earns its place on both.
