OUR TEAM
JMB Constructions, has operated for more than 15 years as a registered building practitioner, working on numerous commercial and domestic projects throughout regional Victoria.
​
In an increasingly competitive market we created a new division of our business JMB Modular Buildings, founded with foresight that the modular sector within the construction industry (commercial and residential) is growing rapidly.
Upon completion of our first modular project JMB Modular Buildings was recognised at the Australian Construction Awards for ‘Off Site Project of the Year' (runner up) and ‘Architectural Design of the Year' (shortlisted), which is a credit to our talented team.
​
Our in-house team comprises construction professionals, contract administrators, architects, and trades, all with deep experience in government-funded infrastructure. This ensures a seamless end-to-end delivery process, from early engagement through to handover and post-construction support.
