At Digger Brothers Building we are a local family owned and operated residential building company based in the beautiful seaside town of Gerringong in NSW.

We specialise in custom builds, renovations, secondary dwellings and granny flats as well as duplexes, while servicing the greater Kiama region including Gerroa, Gerringong, Kiama Heights, Berry and surrounds.

With over 12+ years experience in the building and construction industry our focus is to provide you with not only exceptional workmanship and quality finishes but a memorable and positive experience the entire way through the construction process.

Building a new home or renovating an existing one should be a special milestone in your life yet it can often be met with uncertainty and anxiety around the building process.

We are here to take the stress out of what should be an exciting time and we understand the step you are taking in trusting us as your chosen custom builder.

Our process is simple; from the moment we meet you (and we are happy to come to you) we will work with you to ensure your vision for your custom build comes to life.

Our team will be in regular communication by phone and email to ensure you are kept up to date on each stage of your custom build.
