How much do you charge per square metre?

cost of a knock down rebuild

We often get asked, “How much do you charge per square metre?”

And though the question of cost is reasonable, the assumption that a generic cost can be applied to every house build is not.

At least not with a custom home build.

Some builders offer standard “out-of-the-box” home designs with a standard set of inclusions. Without any variation to the build (and any problems during building), they can tell you exactly how much you can expect to pay per square metre.

At Rosin Bros, we specialise in custom home designs and knock down rebuilds. Every block is different, every client is different, and every home is different. We don’t stipulate a standard set of inclusions, or require you to have X amount of rooms in Y layout.

At the very start, we introduce you to an experienced building designer/architect to help you create the home of your dreams. You can combine the designer’s suggestions, along with your own thoughts and the designs of homes you admire, to develop a blueprint of a home that meets your every want and need.

You will also be introduced to an interior designer who can help you choose the right floor coverings, tile selection, kitchen design, and so on to suit your individual taste and style.

A custom design is truly that. Every element is yours to create.

Here are a few components that affect the overall price of a new home build:

  • Slope of the land and difficulty of excavation
  • Size of the home
  • Inclusions (choice of flooring, tiling, fixtures and so on)
  • Additions (patio coverings, decking, landscaping, etc)

Once you have your design and inclusions confirmed we can work out the square metre cost for you. As with any house build, this may change slightly if any issues present during building, or if you change your mind about inclusions.

So generally, a square metre rate is always calculated after a house is designed and costed.

It is only ever the base of costing a house if that house and build is very “standard”. And even then, every change you make and every issue encountered during building will affect that cost – as many new home builders have come to find when building with a “standard package”!
