What we do

Barnett Building is Sydney’s North Shore extension and renovations specialists. We are second generation builders, having grown up in the industry and have 20 years’ experience in the building industry.

We specialise in building extensions, additions and renovations in Sydney’s North Shore and Northern suburbs, focusing on client satisfaction rather than large volume. Our team of tradesmen and suppliers have a long standing partnership with us which results in consistent high quality workmanship.

Our service is tailored to the needs of each client — you can come to us with your architectural drawings ready to go; or if you haven’t got that far, we can explore your great ideas to improve your home and guide you through the process to get you started.

Your home is your castle – we get that.
