Imagine buying a new car,the big day arrives when you go to collect it, but as you’re leaving the dealership and reach to turn on the radio, you see there isn’t one! You quickly u-turn back into the dealership and upon inquiry are informed that not only are you without a radio but a spare wheel, indicators and airbags. Although these were included in the original quote you now need to pay extra!

Happily this is not usually the case when buying a car, but unhappily is typical when building or renovating.

Why is it that when we purchase any other product or service, we pay the quoted amount and normally get what we pay for? Not so when building or renovating; the most common experience being that the building contractor asks for more money than originally quoted at some point during the project. The client is then left to find additional finance, to complete the project. At the very least, they have a fight with the builder on their hands, are over budget, and have a “shortfall” in their building bond, at worst, severely financially compromised.

Why is this experience so common? The reason is that it is an extremely technical and time consuming process to accurately calculate the cost of building, a skill held by only the most professional contractors. As a result most quotes are based on the highly inaccurate “square metre rate”……

As the above simple analogy demonstrates:

A Toyota and a Ferrari are exactly the same size in m2, and have the same features: they both have four wheels, a windscreen, steering wheel, headlights etc. Should they both be the same price?

Seriously though, just the shape of a house alone can affect the price drastically i.e.:

House ‘A’ measures 10×10m (square), and ‘B’ 25×4m (rectangle), both are exactly 100m2.

But, the walls of ‘A’ are 40m long and the walls of ‘B’ are 58m long. This is an extra 18m of walling, almost 50% difference. This inaccuracy alone would cost an extra R40, 000.00
