Second storey extensions
Second storey extensions in Melbourne — engineered, honest, sympathetic.
Adding a second level is the single biggest structural change most homes will ever go through. We plan for the disruption, engineer for the long term, and finish so the addition reads as always-there.
The RenoWorx second storey
Double your footprint without losing the character of the home below.
A second storey extension is a full structural build sitting on top of an already-lived-in home. Get the engineering, weatherproofing and staging right and it becomes the best value-add on the market. Get any of those wrong and it becomes a nightmare. Our second storey work in Melbourne is designed by architects, engineered by a structural consultant we've worked with for a decade, and built by a fixed site team from set-out through to handover.

Where we build
Second storey extensions across Melbourne's Inner West.
Most of our second storey work sits between Newport and Yarraville, with heritage overlays that need careful set-backs and sympathetic materials. Each suburb has its own council rhythm — we know them all.
