We are fully licensed and insured commercial contractors, holding comprehensive Class A and B Asbestos Licences. This ensures all works, including hazardous material removal and waste tracking, are completed safely and in strict accordance with Australian standards and environmental regulations.


With competitive fixed-price tenders, rapid quoting, and an uncompromising focus on health, safety, and compliance, Brisbane City Demolition is a trusted delivery partner for commercial builders, property developers, and government agencies.
Our operational team prioritizes sustainable demolition practices on every project, actively recovering and recycling materials wherever possible to reduce environmental impact and support Green Star project certifications.
At Brisbane City Demolition, our mission is to deliver safe, sustainable, and professional demolition services with integrity, care, and a deep commitment to our community and environment. We believe that where buildings end, stories begin. This belief drives us to approach every project with respect for the past and responsibility for the future.
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.

Known within the Brisbane community for delivering consistent, high-quality demolition services with a focus on safety, compliance, and customer satisfaction.

As a leading commercial demolition contractor in Brisbane, we specialise in delivering high-stakes projects with precision, safety, and a personal touch that larger firms lack. Unlike many corporate contractors, owners Jen & Oisin are personally involved in every project, ensuring that our high standards for WHS compliance and site efficiency are met from the first day to the final site clearance. Whether you are a property developer, a tiered builder, or a local business owner, you get the benefit of direct owner-oversight on-site, providing the plant, equipment, and expert project management needed to keep your construction schedule on track.


A commercial strip-out (or de-fit) involves removing internal partitions, ceilings, and flooring to return a space to its base building condition, ready for a new tenant or redevelopment. This approach is essential for retail shops, offices, and hospitality venues looking to modernise or repurpose their footprint quickly and safely. We manage the entire process from service disconnections to final waste removal ensuring your site is clean, compliant, and ready for the next stage of construction.

The Critical Path: 4 to 12 Weeks
Commercial demolition is rarely "plug and play." Depending on the site’s scale and zoning, approvals can take anywhere from 4 to 12 weeks. Between DA requirements, service disconnections, and environmental clearances, the "paperwork phase" is often the longest part of the project.

Compliance & Risk Mitigation
We specialize in the critical path of your project. Beyond the demolition itself, we provide the technical documentation and guidance required to navigate Brisbane City Council regulations. We help you secure the necessary BA and DA permits early, ensuring your project remains on schedule and fully compliant with WHSQ standards.
I highly recommend Brisbane City Demolition. They completed the job quickly and efficiently—finishing in half the estimated time. Not only did they offer the most competitive quote in the area, but they also went above and beyond what other companies promised. The team was professional, provided clear communication, and even shared photos of their excellent work. I will definitely use them again when needed. Thank you!

Absolutely flawless! The team at Brisbane City Demolition, led by Jen & O'sheen, did an outstanding job. O'sheen ensured he fully understood the project requirements before starting, and both were punctual, courteous, and highly professional. They treated my property with respect and left the site clean and tidy. This was one of the best examples of quality tradesman-ship I’ve ever experienced.

Brisbane City Demolition supported us throughout the demolition of two homes in Brisbane for our company. They provided a seamless, all-in-one service—quick with the quotation, efficient with the work, and thorough with the paperwork. We highly recommend the team at Brisbane City Demolition!
