Cost by size

The size of your home will play an important role in the cost of your project. Greater room sizes means more materials and labour. To give you an idea, we’ve provided some cost ranges based on small, standard and large home renovations:

Small: $30’000 – $60’000
Standard: $50’000 – $90’000
Large: $90’000


There are dozens if not hundreds of options when it comes to materials and fixtures. Each range in quality and of course price. We suggest using Pinterest or going to a builder directly (they shouldn’t charge) for home renovation ideas. Below is a cost guidance for the various items you may consider for your home:

Design and layout

For any renovation, no matter the size or level of quality, changes to the layout will add serious costs. However these can add enormous value by perfecting original design errors and adding functionality. It’s very difficult to provide cost guidance for these changes. But expect costs to exceed the guidance ranges when making changes to:

● Walls
● Appliance positioning
● Benchtops
● Cabinetry

Understanding the costs

All types of renovations are a big investment for anyone. So, it’s important to understand exactly what you’re getting and why it costs as much as it does. Any building or renovation company you speak to, should be happy to give you an itemised cost break-down of all works involved (if they don’t, run).
