Your home is where life happens. When it stops working for you, a good renovation can change everything.
ONQ Building Group renovates homes across Melbourne's western and inner city. Whether it's a single tired room or a whole-home transformation, we're a family-owned, registered building business that takes care of the lot, with clear communication and a fixed, itemised quote before we start. No surprises. No shortcuts. Just a home that finally feels like yours again.
ONQ Building Group handles home renovations of every size across Melbourne, from a single room through to a full structural transformation. We manage every trade and every detail under one roof, so you have one team and one clear plan from start to finish. Our home renovations include:
However far you want to go, we bring craftsmanship, clear timelines and honest pricing to every step.
We're not the biggest builder in Melbourne, and we like it that way. Being family-owned means every home we work on matters, because our name is on it.
Your renovation is led by Brendan Cefai, a registered building practitioner, so everything is completed to code and properly backed.
You'll know the number before we begin, and where every dollar is going. No creeping costs, no nasty surprises at the end.
We keep you updated at every stage. You'll never be left wondering what's happening in your own home.
We've built a crew that takes pride in the work, turns up on time, and treats your home like their own.
We work right across Melbourne's western suburbs and inner city, so we're never far away.
We respect your home from day one to handover. That means protected floors, daily clean-ups, and a renovation that ends with your home looking better than when we arrived — not like a building site that just packed up and left.
A whole-home renovation can feel daunting. Our job is to make it feel like a plan coming together, not a building site taking over your life.
We start with a no-pressure conversation about your home, your wish list and your budget.
We plan the renovation around how your family lives, then put it all in writing with a fixed, itemised price.
One managed team handles every trade, on a clear timeline, with regular updates so you always know where things are at.
We hand back a home that's ready to live in, and stand behind the work long after the last tradie leaves.
Home renovations vary more than any other project, because the scope runs from a single room to an entire house. That's why an honest number only comes from a proper look at your home.
Rather than a vague range, we give every client a fixed, itemised quote after understanding exactly what you're after. For a full breakdown of what renovations cost across Melbourne, including how pricing works per square metre and what drives it up or down, have a read of our honest guide.
