Mark Roberts from Roberts Builders Pty Ltd

Trevor and Glenice Roberts started the business in 1986 and whilst it has evolved over the years, it remains a family business, with son Mark starting his apprenticeship with Trevor as a builder in 1998. Mark along with wife Andrea taking over management and operations in 2008.

As a custom home builder, we have expertise in delivering new designer-built homes, sustainable homes, off grid and architecturally designed houses as well as commercial and industrial building projects. We are passionate about seeing your dreams come to life and find it satisfying watching your vision go from a dream house on paper to a completed home. Just as you will be experiencing the excitement of receiving the keys to your finished home, we are too.

Roberts Builders can help with your house extension or internal home renovations including bathroom, kitchen, loungeroom, dining and bedroom remodelling. As an NDIS provider, we are also experienced with accessible home modifications that support independent living.  Chat to us about your home renovation and extension plans or how a deck, pergola or patio can extend your living space and turn an unused area of your backyard into a multipurpose outdoor entertaining area.

The entire Roberts Builders team take pride in seeing our craftsmanship turn your vision into a reality. Our site managers, carpenters and trades regularly get feedback from homeowners that they have done an awesome job, that they maintain a clean and tidy workplace and that they are friendly and have a can do attitude where nothing is too hard or impossible, even on the most challenging architectural projects. At Roberts Builders, we only use and recommend reputable and reliable trades who provide an exceptional product and service, and who uphold our strict standards of quality.

We are proud to say that we have a crew of dedicated team members with some of our longest-standing crew being with us for between 12 and 20 years. The team enjoy being onsite together and working on the range of interesting and challenging residential and commercial construction projects which come with working for a regional custom builder.
