Why we do it

To build a company that would attract exceptionally talented individuals.

People who share the founding partners’ commitment to the pursuit of quality.This idea sits behind everything we do. To date, we have successfully grown the company into one with a reputation for quality and meeting demanding challenges. We have built a team of capable people that contribute freely to our collective knowledge and skill as a builder.

This is the driving force behind our business – to do things our way. To do things properly, but also efficiently and in a way that, above all, lets us meet and exceed the expectations of our clients. We take construction challenges and make bespoke solutions that work, and work well. For over a decade 3B has operated successfully as a Tier 3 builder, yet our team has delivered some of WA’s most prominent projects.

It’s time for a New Era at 3B Build. We are ready to take our team and apply their in-depth expertise to larger and more complex projects. We want to build on our achievements as a company and grow steadily into new sectors and areas.

How we grow is important to us, and in this New Era we wish to attract exceptionally talented, like-minded individuals with the same desire and drive to achieve our goals together. We continually strive to be at the forefront of new and innovative construction methods and practices, keeping an open mind as we grow and always challenging ourselves as a business. Our focus as a business is one of respect, openness, and cooperation, enabling each person to be part of the business’ success and share in the rewards of our growth.

“We have regularly teamed up with 3B Build on Design & Construct projects in Perth and have always found them to be an honest and reputable partner.

Projects with 3B have always been successful due to their experience in design and construction management. We have established a great working relationship with Stuart, Sam, Billy & the team and would highly recommend them.”
