Family-Owned. Trusted Locally. Committed to a Greener Future.
At Brisbane City Demolition, demolition is more than just a job — it’s our family legacy.
Led by Oisin O’Sullivan and Jenneffer McKiernan, a proud third-generation demolisher, our business carries forward decades of experience, integrity, and dedication. With deep roots in the industry and a passion for hard, honest work, in the past decade Jen has helped shape Brisbane’s demolition landscape. Her reputation for excellence has been recognised nationwide — as featured on Demolition Down Under, The Project, and the Discovery Channel.
As a family-owned and operated business, we understand the importance of relationships. We know that behind every building is a story, and we treat every project — big or small — with the respect, care, and professionalism it deserves. Our clients are more than just customers — they’re part of our community, and we’re proud to serve them with honesty, reliability, and heart.
We’re also passionate about protecting the environment we all share. That’s why we go above and beyond to recycle materials, reduce waste, and work sustainably on every site. From salvaging timber and steel to crushing concrete for reuse, we’re committed to doing our part for a cleaner, greener Brisbane.
At Brisbane City Demolition, we don’t just clear the way for what’s next — we do it with care, experience, and a deep sense of responsibility to our clients and our environment.
