About Us

Gavin Antonio, founder of GJ Antonio Building Pty Ltd, has been working in the building and construction industry since 1993. He has always been based in the Darling Downs, working extensively in Toowoomba and rural areas of the Downs.

Gavin has successfully been operating as an independent builder for over 5 years, based in Toowoomba, and during this time he has consistently grown the business of GJ Antonio Building Pty Ltd.

As a deserving recipient of several awards, GJ Antonio Building invests that award winning effort into every project undertaken, from the small to the large and everything in between. Specialising in new homes, renovations and extensions, from modern to classic heritage homes, clients can be sure the finest materials available are used.

It takes more than just one person to run a successful building business, and the expert tradespersons who work at GJ Antonio Building take pride in their craftsmanship to build well designed and soundly constructed homes.

Testimonials

Gavin is so reliable and honest, it's what made building our first home a much easier task than we ever anticipated. His workmanship is exceptional and his sub contractors work could not be faulted. Darryl Lindenmeyer from Carinloch Cabinets, tilers, Dave and Veronica Kowitz, Wade Dodd and his team of painters and plumber Craig Bennett (Craig's Country Plumbing) were perfectionists. We would happily build with Gavin and his team again and highly recommend his work to others.

The home Gavin, GJ Antonio built for us in Millmerran was an easy and positive experience right from the start. The communication was great and he gave helpful advice to us on any matters that improved the quality and finish of our home. Gavin always consulted with us on all aspects of the building process.

At the same time we also built another home with a larger spec builder who were big on spin but not so on the finished product and the two experiences could not have been different. This certainly showed us the value of a quality builder, GJ Antonio, who actively oversees his building projects. We cannot fault Gavin for his professionalism, standard of work, and the quality of his tradesman on the job.

Thank you to all for making our first build a great experience. All who have worked on site have been very helpful, friendly and professional in their job. You have not only built us a house, but also a home that we are truly proud of - as you all should be.
Amanda and Daryl McLoughlin

It is with great pleasure that we provide this testimonial on behalf of Gavin Antonio and GJ Antonio Building Pty Ltd. After a word of mouth recommendation, Gavin was approached in May 2009 to quote on building a residence on our mixed farming property near Millmerran.

Building commenced in mid June and was completed by early September 2009. The whole process from beginning to completion was fast, absolutely trouble free and so easy. Gavin’s reputation as a builder of excellence has been earned and is supported by his dedication and hard work, his attention to detail, his knowledge, his easy, open and helpful communication, his honesty and his integrity.

It is without hesitation that we recommend the services of Gavin Antonio and GJ Antonio Building Pty Ltd.
