It’s a given that every construction company needs to deliver on time, to budget, with quality. And we’re no exception. But we’re also far more than that.

Independent and Australian-owned, we are a specialist in the art of problem solving to turn visions into reality. 

With 25 years in the market we like to think we’ve earned our stripes. We have a repeat client base, the financial capacity to deliver projects up to $150 million, and – thanks to our people and experience – NSW Government pre-qualification up to $53 million.

But we think it’s our innovation that truly sets us apart. Our ability to work collaboratively, as true partners, design experts, construction experts and engineering experts to help turn even the most complex ideas into tangible, workable and successful projects.

With over 100 employees, we build educational campuses, aged care and retirement living buildings, complex mixed use and high quality residential projects, CBD projects on constrained sites, commercial and industrial facilities. We work through a range of contract mechanisms from Early Contractor Involvement (ECI), to Design and Construct and Lump Sum Construct Only.

Our Vision

Our vision at Duffy Kennedy is simple – to be Australia’s most client-focused building company. We work tirelessly to achieve this goal by listening closely, understanding and responding to our clients’ needs in a unique way. We are a progressive company supported by a strong set of traditional values which guide our behaviour and are integral to our culture. Striving for excellence in every aspect of our role, we pride ourselves on both our diligence and ingenuity, with the needs of our clients at the heart of everything we do.
