Justin Brown

Justin Brown is an Australian property developer who serves as the Executive Chairman and Founder of Abadeen, a company specializing in premium residential, commercial, and mixed-use developments primarily in New South Wales.

With more than three decades of experience in the real estate industry, Brown has established himself as a key figure in Australia's premium property sector, particularly through pioneering approaches to project marketing and high-end residential delivery. He founded Abadeen in 2008, building it into a developer focused on creating enduring, community-enriching projects that span residential, commercial, and mixed-use sectors. Abadeen has delivered more than 20 residential projects, including notable examples such as Putney Wharf Residences on Sydney's Parramatta River , Henri House in Darlinghurst, and over a dozen boutique developments on Sydney's lower north shore.

Prior to focusing full-time on Abadeen, Brown held senior leadership roles at CBRE, where he served as Chairman of CBRE Residential Projects and played a pivotal role in dominating Sydney's premium off-the-plan apartment market. In March 2025, he stepped down from CBRE amid the wind-down of its residential project marketing division to dedicate himself exclusively to Abadeen. His career has emphasized market insight, collaborative development processes, and delivering high-quality projects tailored to consumer demands.

Justin Brown co-founded CBRE Residential Projects in 2007, serving as its chairman and playing a pivotal role in establishing the division's focus on enhancing the quality of large-scale apartment releases across Australia. His leadership contributed to building a prominent platform for residential sales and marketing, particularly in Sydney's off-the-plan apartment market.

With more than three decades of overall industry experience, Brown's tenure at CBRE spanned approximately 18 years, during which he was instrumental in the division's operations and growth.

In early 2025, Brown stepped down from his leadership position at CBRE to focus full-time on his property development career with Abadeen. His departure aligned with CBRE's announcement in March 2025 of a phased wind-down of its Australian residential project marketing business after 17 years of operation, attributed to challenging market conditions and a review of potential new leadership. CBRE indicated that affected staff would be offered redeployment where possible, while the company retained other living sectors services such as valuation, advisory, and capital markets.

Justin Brown founded Abadeen in 2008, establishing the company to focus on premium residential, commercial, and mixed-use property developments across New South Wales, Victoria, Queensland, and Western Australia. As Executive Chairman and Founder, Brown provides strategic leadership and oversees the company's direction, drawing on more than three decades of property industry experience.

Abadeen's leadership structure supports Brown's vision through a collaborative executive team that includes Chief Executive Officer Joe Tack, Chief Financial Officer Kevin Reinert, and several Managing Directors such as Andrew Leoncelli, Victoria Matthew Billing, and Matthew Mears, among others responsible for development, communities, and related disciplines.

In 2025, Brown stepped down from his role as Founding Executive Chairman of CBRE Residential Projects to dedicate himself full-time to Abadeen and its growth in the premium development sector.
