StreetBuild are always looking for driven and dedicated
new talent to join our growing team.



In 1998, Graeme Street found himself with over 30 years of domestic and commercial construction experience comfortably under his belt, but with a burning desire to build on this knowledge, challenge the status quo and develop industry best practices. So, from his re-purposed garage office in Sydney, Graeme established the Streetbuild brand. With his innate attention to detail, strong business ethics and admirable reputation, Streetbuild quickly landed its first project with one of Australia’s largest retailers – Woolworths.  

From such humble beginnings, Streetbuild quickly established a thriving reputation that saw it expand across states to open a second office in Queensland in 2008. Fastforward to today, Streetbuild is now a trusted construction partner across retail, education, hospitality, commercial and industrial projects servicing seven states with projects ranging from small refurbishments to multi-million dollar builds.

“I have always strived for better. That has been the core attribute of our sustained success over the last 25 years.

That is the Streetbuild way.”

- Graeme Street (Founding Director)




We firmly believe that our integrity has been one of the most crucial elements of our 20+ year success: setting the foundation of each client relationship and enabling us to become the trusted partner of over 30 organisations across Australia.


We seek to recognise and understand the unique challenges, needs and perspectives of all stakeholders. Our process ensures each project is designed and developed with the purpose in mind from the very beginning. This equates to happy customers which is our greatest measure of success.


Building something new should be exciting! We thrive in environments where our clients, team and wider stakeholders feel engaged. We find satisfaction in producing beautiful and functional projects for our clients and in being able to celebrate in their success.


Passion is the first step towards excellence. We are determined, resourceful and uphold the highest levels of safety and construction best practice while also executing state-of-the-art design that has a true impact for our client’s and their customers.



A career in construction can be filled with opportunities to sharpen your problem solving, negotiation, time and people management skills. However, to do so effectively, you also need an environment which encourages you to learn and challenge the status quo. That’s where we come in. 

With an average tenue of 5 years, Streetbuild is well above the 3-year national average, accredited not only to the environment that we’ve created for our team, but they themselves which have cultivated and upheld our culture.  

We are passionate about developing our team with direct access to mentoring from our senior and executive management, including our Founding Director Graeme Street.
