Keeping It Simple: Our Stonnington Home Extension Process

Your extension from start to finish

Home renovations are notoriously stressful — it’s hard to tell if corners are cut, or when and why the budgets and timelines keep growing. The key to Supa Group’s straightforward home extension process is transparency. You can be as involved as you like in every stage of the process. In fact, we welcome it. And if you’d rather stay hands-off, your project manager will still provide progress updates upon request. No hidden fees, no confusing jargon — just open communication, reliable promises and stunning results. Simple.
