~ Client Testimonial ~

“We didn’t give Al an easy project. He turned up on his first site visit to see we had demolished half of a 100-year old property and we had grand plans to integrate an architecturally designed home into what remained. Even the Engineer in me was nervous as to how he would achieve this. After I saw how much detail and thought he put in to tying the old structure with the new, I had full confidence he could tackle any challenge.”

MBA Member

As the founder of AJ Andoni Building, Alan knew from a very young age that he wanted to work with his hands.

Over the years he saw himself building upon his skill set whilst working for one of Australia’s leading residential builders, overseeing top end architecturally designed projects across Sydney NSW. From there he returned to Newcastle to work as a Project Manager on NSW Government projects.

It was from here that he decided to start his own company, taking with him all the knowledge gained over the years.

Alan’s journey enabled him to establish a comprehensive and high level of critical thinking that he could apply to building. His experience empowered him to embrace a strong degree of professionalism and a true understanding of managing client relationships.

A family man and father of 3 small children, Alan knows the importance of making your house a home.

~ Client Testimonial ~

“Al and the team really feel like family after building our home. We actually had to explain to our kids that Al and the guys won’t be living with us when we move in to our new home. Fred (our 2.5yr old) legitimately thought Tobin and Al would be living upstairs"
