Not All Square Metre Rates Are Created Equal
When you’re planning your new home, square metre (sqm) rates can seem like a helpful way to compare costs. But if you're relying on those numbers alone, you could be in for a surprise. As an experienced home builder, we know that sqm rates don’t always tell the full story. If you’re considering a design and build approach, it’s important to look beyond the surface. Here’s why.

1. The Design Impacts the Cost
Two homes might have the same floor area, but their build cost can be very different. That’s because the design plays a big role in determining materials, labour, and time. A simple, rectangular layout is usually more cost-effective than a complex shape with multiple corners, split levels, or custom features. More complexity often means:
- More cladding and roofing materials
- Extra labour
- Additional interior work like insulation, painting, and finishing
2. Inclusions Vary from Builder to Builder
Some sqm rates cover just the basics. Others include more features – or even the essentials. It’s crucial to ask exactly what’s included in your build price. Look for clarity on:
- Kitchen and bathroom fittings
- Flooring options
- Driveways, fencing, and patios
- Landscaping, window coverings, and lighting
- Site-specific costs like earthworks, wind zones, or council requirements
A design and build process allows you to customise these elements, but make sure you understand what’s factored into the final price.
3. Smaller Homes Can Cost More Per Square Metre
It’s a common misconception that smaller homes are always cheaper. In reality, areas like kitchens and bathrooms tend to be the most expensive per metre – and these are required no matter how large the home is. So, while the overall price may be lower, the square metre rate can actually be higher in a compact design.
4. Not All Floor Areas Are Measured Equally
Different home builders measure floor areas in different ways. Some include garages, porches, or roofed outdoor areas in their sqm calculations, while others don’t. That can make it hard to compare quotes like-for-like.
At Platinum Homes, we’re transparent about how we measure floor area – and we’ll talk you through exactly what’s included.
