Take the wall out. Here's what it actually costs.

Most load-bearing wall removals in Melbourne run $6,000 to $12,000 all in — that includes the structural engineer’s design, the building permit and its fees, temporary propping, the steel or LVL beam, installation, and full plaster and flooring make-good.

A non-load-bearing partition is far less: $2,500 to $4,500, with no permit required.

Larger open-plan conversions involving multiple walls, long spans, or load coming down from an upper storey run $14,000 to $28,000, because they need more substantial beams and often new footings under the new load points.

Yes, if the wall is load-bearing. Removing or altering a load-bearing part of a building requires a building permit in Victoria. There’s no small-job exemption and no way around it.

That permit process means a structural engineer designs and sizes the replacement beam, a registered building surveyor issues the permit against those computations, the work is inspected at mandatory stages, and you get documentation at the end.

If the wall is genuinely non-load-bearing — a partition holding up nothing but itself — no building permit is required. Our free structural check tells you which one you have before you’ve spent anything.

Skipping the permit on structural work is a problem you inherit later: it surfaces in a conveyancing search when you sell, and it can compromise an insurance claim connected to the structure.

You can’t know reliably from inside the room, and this is the one question worth getting right, because it roughly triples the cost.

Reasonable indicators that a wall might be load-bearing: it runs perpendicular to the floor joists, it sits directly above a beam or a line of stumps, it continues through to the storey above, it’s an original external wall that was built over, or it’s near the centre of the house running along its length.

None of those are conclusive. Internal brick walls in older homes are often load-bearing; stud walls sometimes are too. The only reliable check is someone getting into the roof space to see what bears on it and under the floor to see what’s beneath it.

We do that check for free before you commit to anything.

Usually not. In most single-storey homes the beam can be recessed up into the ceiling space so the finished room reads as though the wall was never there — flush ceiling, continuous cornice, no visible evidence.

Whether that’s possible depends on the depth of beam the engineer specifies and how much room there is above the ceiling. Deep beams carrying an upper storey sometimes can’t be fully concealed.

We tell you which outcome you’re getting before you commit, not after the plaster is up. Where the beam genuinely has to show, some clients choose to expose the steel deliberately and finish it properly — which reads as a design decision rather than a compromise.

On site: about a week for a non-load-bearing partition, two to three weeks for a load-bearing wall including plaster make-good and painting.

Before site, allow two to four weeks for the structural engineer’s computations and the building permit. That’s the part people don’t plan for. We start it the day you approve the quote and run it in parallel with everything else.

Total from “yes” to finished room is typically four to seven weeks for a standard load-bearing removal.

The engineer decides, based on the span and the load. It isn’t a preference.

LVL (laminated veneer lumber) suits shorter spans and lighter loads. It’s cheaper, lighter, easier to get into a house without removing a window, and it can be fixed to with ordinary carpentry.

Steel handles longer spans and heavier loads in a shallower depth, which is often what makes a flush ceiling possible. It’s more expensive, needs craning or several people to lift, and sometimes needs new footings beneath its bearing points.

A common outcome in Melbourne homes is a steel beam for a span over about four metres or where an upper storey is carried, and LVL below that.

Yes, in most cases. We seal the work zone with dust barriers, protect floors and pathways, and clean down daily.

There will be two or three genuinely disruptive days — demolition, and the day the beam goes in — with significant noise and vibration. Power to that part of the house may be off for periods while electrical is relocated.

For a single-room removal, staying is normal. For a major open-plan conversion joining several spaces, most clients find it easier to be elsewhere for the demolition week.

Electrical is included in every wall removal package — power points and switches in the removed wall are relocated to the nearest sensible position by a licensed electrician, and we discuss where you want them before it happens.

Ducted heating runs and plumbing inside the wall are priced separately, because the cost varies enormously depending on where the duct has to go instead. Sometimes it’s a simple reroute through the floor; sometimes it means reconfiguring a branch of the system.

We identify what’s in the wall during the free structural check — not halfway through demolition. That’s part of the point of doing the check properly.
