Plans sorted. Permits approved. Ready to build. We work with homeowners across Melbourne's inner south who need a builder they can actually rely on.

Rear extension and deck renovation — Nicon Built
Our approach
Your architect has done their job. The plans look right. The permit is through. Now you need a builder who can execute them without shortcuts, without handing the job to strangers, and without it becoming a second full-time job for you.

That's where we come in.
We take on room additions, full home extensions, structural alterations, open-plan conversions, and dual-occupancy additions across Melbourne's inner south and bayside suburbs. Every trade on the job is coordinated by Nicon Built. Tilers, plumbers, plasterers, painters. Our network, our standard, our call on who's on site.

Real renovations don't always go exactly to plan. Materials get discontinued. Walls reveal things the drawings didn't show. Scope shifts. How a builder handles those moments tells you everything about them. Our reviews consistently mention communication and transparency. That's not by accident.
