Led by Vision, Driven by Values

Mosaic was founded on deep experience, uncompromised values, specialised expertise, and a shared passion for creating places of lasting value. Our leadership brings vision, rigour, and integrity across every stage of the property lifecycle.

Uncompromising Standards

Who we are is the sum of every choice, every detail, and every promise we stand by.

Mosaic was founded by Brook Monahan with a simple but uncompromising belief: that property should be created with enduring quality, integrity, and care for the people who call it home.

As Founder and Managing Director, Brook’s vision has always been bigger than buildings. It’s about setting a new benchmark for how development is done — leading with authenticity, delivering without compromise, and outcomes that stands the test of time.

His unwavering commitment to excellence and to keeping customers at the heart of every decision continues to define Mosaic’s culture, drive, and reputation today.

Foundations of a Vision

Mosaic’s origins trace back to 2004, when Founder Brook Monahan set out with a clear vision to create a company that would redefine multi-residential development through quality, integrity, and long-term commitment.

In 2012, the business was rebranded and David Handley joined as Co-Founder. Built on a longstanding friendship forged in the bush many moons ago while working together on cattle stations as young stockmen, and a shared passion for creating and building, their close alignment and commitment to doing development differently shaped Mosaic’s foundations.

From the beginning, Brook set the vision and drove the strategy and momentum, while Dave was responsible for the delivery side of the business.

Together, they created a business and culture that has seen Mosaic grow into one of Queensland’s most respected and trusted developers and builders.

Today, Mosaic is led by a passionate and dynamic executive leadership team that continues to drive this vision forward.

People & Culture

Our success is powered by more than strategy—it’s driven by our people. We don’t shy away from the fact that Mosaic can be intense. The standards are high, the pace is fast, and expectations are clear.

But that intensity is matched by purpose, pride, and a shared drive to create something exceptional. For the right people, it’s an environment that’s not only rewarding but deeply fulfilling.

We bring together individuals with diverse expertise, a commitment to excellence, and the confidence to challenge convention. Each team member is selected not just for their skills, but for their mindset—passionate, collaborative, and aligned with our core values.
