Principal Built Engineering provides engineering analysis and design for load bearing wall removal in Melbourne homes. The engineer confirms whether the wall carries roof, ceiling or floor loads, then designs the beam, posts and footings that take over that load once the wall is removed.
Design documentation is prepared to support the building permit and to give the builder clear construction guidance, so the structure stays sound while the layout opens up.
What a load bearing wall removal design includes
- Site inspection: An engineer attends to check the wall, the roof and floor framing that is visible and safely accessible, and the condition of the surrounding structure.
- Load path assessment: The loads carried by the wall are traced from the roof or upper floor down to the footings.
- Beam and post design: Steel or engineered timber beams, posts and connections are sized for the new opening, including any flush beam set within the ceiling.
- Footings: New pad footings are designed where the posts bring concentrated loads to the ground.
- Temporary propping: Guidance on supporting the structure while the wall is removed, with propping design where the builder needs it documented.
- Drawings and certificate: Structural drawings, computations and the Regulation 126 certificate for the building surveyor.
Is the wall load bearing?
Walls that support roof struts, carry ceiling or floor joists, sit under another wall or form part of the external envelope are usually load bearing. The load bearing wall identification guide explains the common signs, but the answer for a specific wall is confirmed by the engineer on site before any demolition.
For what sets the overall project cost, see the cost to remove a load bearing wall in Melbourne. Larger renovations are covered under residential structural engineering, and where a report on the existing structure is needed first, see structural engineer report Melbourne.

Frequently Asked Questions
Yes. Removing a load bearing wall changes how the house carries its loads, so a structural engineer must design the replacement beam, posts and footings. The building surveyor relies on the engineer’s drawings and certificate to issue the building permit.
In most cases, yes. Structural alterations such as removing a load bearing wall generally need a building permit. The building surveyor confirms the requirement for the specific job.
The engineer looks at what sits on the wall: roof struts, ceiling or floor joists, another wall above, or a beam bearing onto it. This is checked on site from what is visible and safely accessible, together with any original drawings.
It depends on the span and the load. Steel beams and engineered timber beams such as LVL are both common. The engineer sizes the beam, the posts at each end and the footings under them.
Photos of the wall from both sides, a floor plan showing the wall to be removed, the roof type, and whether there is a second storey above. A site inspection then confirms the details.
