We know what it means to stand in front of an aging site that no longer serves its potential — and to imagine what could be built in its place. That’s why we exist.

At Brisbane City Demolition, demolition is more than just a job because it is 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 honest work, Jen has spent the last decade helping shape Brisbane’s demolition landscape. Her reputation for excellence has earned national recognition through features on Demolition Down Under, The Project, and the Discovery Channel.

As a family-owned and operated business, we prioritize relationships. We understand that every building has a story, so we treat every project, regardless of scale, with the respect, care, and professionalism it deserves. To us, our clients are more than just customers; they are part of our community, and we are 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 experience, care, and a deep sense of responsibility to our clients and our environment.
