About JSG Construct
Transforming Melbourne homes since 2013.
Driven by passion and backed by experience, our team works together to bring your dream home project to life.
Our Story
Built around the projects that ask for more.
JSG Construct is a Melbourne building company led by Jeremy Gillen, delivering custom renovations, extensions, and new home builds with a focus on clear communication, detailed planning, and quality workmanship.
Since 2013, JSG has helped homeowners transform older homes, improve family spaces, and bring considered design ideas to life through a structured build process.
The clients who work best with us appreciate a planned approach. They want clear scope, realistic expectations, and a builder who understands the details before construction begins.
We keep our team small and our standards high. Every project we take on, we back with our full focus.

How We Work
The principles we build every project around.
Upfront Communication
We believe surprises belong in birthdays, not in construction projects. You get regular updates, honest answers, and straight talk at every stage.
Structured Pre-Construction
We invest time before construction starts to identify risk, align scope with budget, and give you confidence in what you've agreed to.
No Guess Pricing
Every quote is based on a real, itemised scope, not a square metre rate or a ballpark figure. What we quote is what you pay.
End-to-End Coordination
We manage your engineers, surveyors, designers, and trades. You have one trusted point of contact from assessment through to handover.
Who We Work With
The right client makes the right project.
A short look at the kinds of projects and people we work best with.
- Homeowners who value planning and cost certainty over speed
- Renovations where existing conditions and heritage constraints matter
- Projects requiring problem-solving, not just straightforward builds
- Clients open to a structured, step-by-step process
- Multi-stage or design-led projects needing strong coordination
- Anyone who wants one point of contact from first call to final key
