When people start comparing new homes, one of the first questions that often comes up is, “What does it cost per square metre?” And we completely understand why. It gives you a simple number that feels like an easy way to compare one builder or home with another.
The problem is that cost per square metre only tells you a very small part of the story. A home isn’t just a collection of square metres. It’s where you sleep, raise your family, cook, work, relax and spend a huge proportion of your life. It needs to work for the way you live, keep you comfortable throughout the year and ideally not cost you a fortune to heat, cool and maintain.
So while we absolutely understand why people look at the cost per square metre, we think the bigger conversation should be about what you’re actually getting for your money.
Why smaller homes can look more expensive per square metre
This is probably one of the biggest misconceptions we come across when talking about smaller homes.
If you compare an 80m² home with a 140m² home, there is a good chance the smaller home will have a higher cost per square metre. On the surface, that can make the larger home look like better value, but it doesn’t necessarily mean it is.
Regardless of the size of your house, you still need a kitchen, bathroom, hot water system, electrical switchboard, plumbing, heating, appliances, consent, design work and all of the other infrastructure required to make a home function. These are some of the more expensive parts of a build and you need them whether your home is 70m² or 170m².
Once those costs are covered, adding additional bedrooms, hallway or relatively simple living space can bring the average square metre rate down. So yes, a larger house can quite legitimately have a lower $/m² figure while still costing you significantly more overall.
For example, if a smaller, well-designed home costs $400,000 and a larger alternative costs $550,000, does it really matter that the $550,000 home has a better square metre rate? You’re still spending another $150,000.
That’s why we think a much better question is, “How much house do I actually need to live the way I want to live?”
Making the space you have actually work
We’ve never been particularly interested in building space just for the sake of having more of it. We would rather build a smaller home where every part of it has a purpose than add another 20 or 30 square metres that doesn’t actually improve how you live.
A poorly designed 130m² home can feel less functional than a thoughtfully designed 90m² home. Hallways, awkward corners, oversized rooms and areas that rarely get used all cost money to build, and once you’ve built them, you then have to heat them, cool them, clean them and maintain them for the life of the house.
This is why the design process is such an important part of what we do at Whio Homes. We want to understand how you actually live. What storage do you need? Where does everyone dump their bags when they walk through the door? Do you need a formal dining area, or would that space be better used somewhere else? Do you work from home? Where do you want the sun at different times of the day?
Those conversations are much more important to us than simply trying to fit as many square metres as possible onto a floor plan. A home that functions properly has value, even if that value doesn’t show up in a $/m² calculation.
What will the home cost you after you move in?
The build price is obviously important, but it’s also only the beginning of what your home will cost you.
Once you move in, you have to heat it in winter and potentially cool it in summer. If the house loses heat quickly, you are paying for more energy to keep it comfortable. If it overheats badly in summer, you may end up relying on air conditioning to make it liveable.
That might only be an extra amount each week or month, but over 10, 20 or 30 years of living in a house, those costs add up.
This is one of the reasons we have invested so much time into understanding the performance of the homes we build. We look at insulation, glazing, orientation, materials and the overall building envelope because we want our homes to naturally maintain a more comfortable internal environment rather than relying solely on heating and cooling to do the job.
Our thermal modelling has demonstrated just how significant that can be. In one comparison, the standard home model spent around 8% of the year above 25°C internally, compared with just 0.1% for the Whio Homes specification.
For us, that isn’t just about saving money on a power bill. It’s about what your home actually feels like to live in every day.
And then there is your health
This is probably one of the hardest things to put a dollar value on, but it’s also one of the biggest reasons Whio Homes exists.
We spend a huge amount of our lives inside our homes, surrounded by the materials they are built from, yet health and indoor air quality can easily become secondary considerations when we are trying to get a build price down.
We have deliberately taken a different approach. Our ForeverBreathe-aligned specification uses materials such as Magnum Board interior linings, Terra Lana wool insulation and low-VOC finishes because we want to know what we’re putting into our homes and what our clients will be living with every day.
Are there cheaper products available? Absolutely. But the cheapest product isn’t automatically the product that represents the best value.
It comes back to that same question around value perception. How much is a healthier internal environment worth to you and your family? There isn’t a neat $/m² number we can attach to that, but that doesn’t make it any less important.
The cheapest product can become the expensive one
The same thinking applies to the materials and finishes that go into your home.
It can be tempting during a build to look at two products and simply choose the cheaper one. Sometimes that is completely appropriate and spending more won’t necessarily give you a better result. Other times, saving a relatively small amount upfront can create a much larger cost later.
If a cheaper flooring product, fitting, piece of hardware or finish needs replacing years earlier, you don’t just have the cost of buying it again. You have the labour involved in removing it, disposal costs, replacement materials, installation and potentially painting or other remedial work around it. There is also the disruption of having part of your home pulled apart while the work is completed.
We don’t believe that means you need to put the most expensive product available into every part of your home. Far from it. We believe in putting the money where it matters and looking at durability, performance, health, maintenance and expected lifespan alongside the initial purchase price.
Sometimes spending a little more upfront is the cheaper decision over the life of the home.
So what does value actually mean?
This is really the conversation we want people to have when they’re comparing homes.
Of course you need to know what the house is going to cost to build, and cost per square metre can be useful as one part of that comparison. But it shouldn’t be the only number driving a decision as important as this.
We think you should also be asking what the home will cost to heat and cool, how much maintenance it is likely to need, which products will need replacing and when, whether you’re paying to build space you don’t really need, and whether the layout genuinely works for your lifestyle.
Then there are the things that are harder to put into a spreadsheet: How comfortable will the home be in the middle of winter or on a hot summer afternoon? What materials are you surrounding your family with? How does the home feel to live in? Does it make your day-to-day life easier?
At Whio Homes, we’re not setting out to build the cheapest home per square metre, because that has never been the goal. We want to build homes that provide better value over the time you own them — thoughtfully sized homes that function well, use better materials, require less energy to stay comfortable and have been designed with both people and the environment in mind.
At the end of the day, you don’t live in a cost-per-square-metre calculation. You live in your home.
And we think that’s a much better way to think about value.
