Why the old reliable per square meter metric isn’t so…reliable

We completely understand that as you embark on a renovation, you want a rough idea of the costs involved…a rough estimate.  However, as we discuss on our Pricing Page in more detail, relying on a rough estimate can be, at best, unhelpful, and at worst, a recipe for a budgeting disaster.

Here are the 12 main reasons why rough estimates lead to confusion and frustration for homeowners down the line:

1. Lack of Honesty and Accountability: In my experience, I have yet to encounter an honest rough cost estimate. Online figures often lack accountability, with many being mere “clickbait” or poorly managed information designed to present the lowest possible cost.

2. Clickbait and Misleading Information: A lot of online data seems created more for attention than for accuracy. It is common to see misleading information that oversimplifies the true costs of construction.

3. Incomplete Scope: Online and anecdotal estimates frequently miss crucial costs. Many rates only cover the bare essentials and exclude finishes and fittings. To understand the true cost of your renovation, every detail, including “other project costs” that some builders may overlook, must be clearly outlined.

4. The “Per Square Meter” Fallacy: This seemingly straightforward metric can be deceptive. Different types of rooms, such as kitchen extensions versus redecorated lounges, have very different costs per square meter. People often underestimate expenses when considering high-density projects, leading to skewed averages.

5. Lack of Transparency: Many sources fail to clarify how their figures are calculated. Essential components like kitchens, doors, and windows, along with labor rates, are rarely detailed.

6. Outdated Information: Construction costs are subject to fluctuations due to inflation and market conditions, which means that older online data can be inaccurate. The reluctance to discuss real construction costs perpetuates a cycle of unrealistic pricing.

7. Incomparable Quality and Ethics: The building industry is largely unregulated, resulting in varying quality and ethical standards. It is common for prices to change once you commit, as some contractors may prioritise filling gaps over delivering quality work.

8. Unrealistic Expectations from “Savings”: Homeowners may try to save money by providing materials or hiring their own subcontractors, which can lead to subpar work and ultimately result in higher costs for repairs.

9. Ignorance of True Scope: Low figures from online searches or friends often omit important elements like finishes, fittings, and professional fees (for architects, structural engineers, and planning).

10. Misinterpretation of “Average” Costs: Generalised “per square meter” rates fail to account for high-cost areas like kitchens and bathrooms, making the overall project seem less expensive than it is.

11. Underestimation of “Other Project Costs”: Homeowners often overlook expenses beyond direct construction, such as parking permits, licenses, skips, and scaffolding, which should be included in a thorough builder’s quote.

12. Competitive Tendering Driving Down Initial Quotes: The traditional tendering process can encourage builders to provide artificially low numbers just to secure a contract, which can lead to higher costs later on through variations and additional expenses.

So how can you find out what your project will cost?

No one wants to face disappointment during a renovation. By being aware of these reasons and understanding why relying on online searches, friends’ suggestions, or outdated square meter costs can lead to pitfalls, you can set yourself up for a much more successful project. If you want to get a true cost of your project enlist the help of a firm a firm that can offer early, detailed pricing. This way, you will clearly understand what is feasible and what isn’t, empowering you with confidence before you embark on your build.
