The advantage of going for a custom builder is they will build a house that has been designed just for you and your block of land. This is really useful if your block has an awkward shape, a tricky elevation or is very small or narrow. A custom build tends to be built in situ and takes into consideration all of the issues and challenges of that particular site.
So how much extra would you pay to get a custom built house? Well, how long is a piece of string? House builds come in all shapes and sizes and the cost per square metre can range from $800 for a very basic design to $10,000 for a top, luxury build.
You’ll also have the additional cost of an architect or draftsperson to design the house, so the dollars can add up pretty quickly, but you’ll end up with something that's going to be unique.
At the end of the day, it comes down to your projected final value and whether you can still make a profit in spite of the extra expense, and also, what does your target market want (and expect).
And that means understanding the demographics of the area you’re building in, and making sure you build a house that suits that demographic. There's no point building a two-storey mansion when the demographics of the area are retirees looking for single-level living. Equally, you’d be mad doing a single storey home if you can get a much larger house with a view and there’s a market for that.
