CBI Construction’s Profile

  • Back in 2020, Justin founded CBI Construction Pty Ltd. after coming home to residential building. Following six years in commercial work, he was driven to create high-performance, sustainable homes that stood for quality craftsmanship.

    Sustainability is at the heart of everything we do at CBI. By 2022, the team were certified as Passive House tradesmen, further cementing our expertise in energy-efficient building.

    Over the last five years, CBI delivered a diverse range of projects—from detailed inner-city terraces to luxury waterfront homes on Pittwater. We pride ourselves on our meticulous attention to detail and commitment to quality, setting the standard for architectural renovations across Sydney’s Northern Beaches.

  • Every day, we must embrace the challenges that come our way. By working together as a team, we can discover the most effective solutions for our clients and our company. Remember, we should never settle for anything less than the standards we set for ourselves.

  • Our goal is to continue building a successful team that are passionate about their work and are always progressing. We want to exceed our clients expectations and be a highly sought after residential construction company.

  • Respect for others - client, property, teammates & neighbours.
