  • We chose Mick and the team at Digger Brothers Building for our major renovation in 2021 for their reputation when it comes to quality. Not only did they exceed our expectations around quality, Mick and the Team delivered earlier than scheduled and came in on budget. This delivery and cost focused result was even more impressive given the shortage in building supplies and the costs of materials skyrocketing during the build.

    The professionalism and communication that is displayed by the whole team at Digger Brothers is exceptional, but the communication from Mick himself was on another level again, we were kept informed on every level throughout the whole build from planning all the way through to execution and delivery (and every detail in between).

  • We chose Digger Brothers following a strong recommendation from a friend.

    Mick took the profession to a new level. His enthusiasm and attention to detail, along with his knowledge and competence, gave us full confidence and trust in his capability to deliver us the home we desired.

    The trait that stood out the most, was his personal approach. We weren’t just another ‘customer’, and he was well aware of the pressures we were under. He patiently and warmly guided us through the process, and did everything in his control to keep the build within budget.

    Viruben Watson – Willowbank, Gerringong
  • Digger Brothers Building renovated our Jamberoo house in 2019 and we were extremely happy with the results. I would highly recommend them. Michael is a great communicator and our project was finished on time and on budget, with great quality work and a lot of attention to detail.

  • It was an absolute pleasure working with Michael Digger and his team to build our Airbnb cottage. Michael has meticulous attention to detail, is genuinely caring and highly responsive to any questions.

    Julie Carlill – Infinity on Willowvale
  • What you have produced has exceeded our expectations. We have effectively a new house on an old footprint, which has enhanced the aspect and view enormously.

About Us

At Digger Brothers Building we are a Gerringong Builder with a strong focus on sustainability and community and ensure that all of our Illawarra and Shoalhaven builds reflect this. 

Our concept of community is at the forefront of every new home that we build in Gerringong, Kiama, Gerroa and throughout the Shoalhaven and Shellharbour. 

We hire local employees, partner with local training organisations, support local sporting teams and events whilst also choosing to work alongside local suppliers and wholesalers. 

This not only creates more jobs within our local region but continually supports our local economy. 

At Digger Brothers Building we are a South Coast NSW Builder with a difference. 

We value transparency, timeliness and attention to detail and we know how important these values are throughout any Kiama, Nowra or Berry build. 

Our team will be in regular communication to ensure you are kept up to date on each stage of your Kiama Renovation or Shoalhaven Custom Build.
