Wall Removal Structural Engineer in Queensland
Planning to remove a load-bearing wall or create a larger opening in your home or commercial building? Ostanes Engineering provides structural assessment, beam and post design, calculations and engineering documentation for wall removal projects across Queensland.
Our structural engineers determine how the existing wall supports the building, then design a replacement load path using steel or LVL beams, posts, connections and supporting foundations.
Structural Engineering for Load-Bearing Wall Removal
Removing a load-bearing wall changes the way loads travel through a building. A wall may support roof framing, ceiling joists, upper-storey floors, or bracing systems. Ostanes designs replacement load paths using steel and timber beams, posts, connections, and supporting foundations across Queensland.
Load-Bearing Wall Removal
Engineering structural load-transfer systems to safely remove internal partition walls, masonry walls, and load-bearing timber frames.
Steel & LVL Beam Sizing (AS 4100)
Universal beam (UB), parallel flange channel (PFC), and laminated veneer lumber (LVL) sizing with deflection limits to prevent plaster cracking.
Steel Columns & Timber Posts
Engineered RHS steel posts, structural studs, and timber columns to transfer heavy point reactions safely down into the floor system.
Flush Ceiling Beam Engineering
Concealed steel beams engineered within the ceiling roof space using joist hangers and side-mount brackets for a completely flat ceiling line.
Supporting Pad Footings & Piers
Designing concrete pad footings, slab thickening details, or subfloor piers to support high-point loads where walls once distributed weight.
Bracing Re-Distribution (AS 1684)
Calculating lateral wind stability (AS 4055) and designing replacement structural bracing panels or steel portal frames when shear walls are removed.
When Do You Need a Structural Engineer for Wall Removal?
Creating Open-Plan Living & Kitchens
Combining dining, living, and kitchen zones into modern open spaces by removing dividing walls and installing engineered steel transfer beams.
Widening Existing Doorways & Openings
Enlarging doorways or interior walkthroughs, designing new lintels, and reinforcing jamb studs to prevent wall settlement.
Bi-Fold & Stacking Sliding Doors
Opening external walls for seamless indoor-outdoor alfresco connections, addressing roof loads, wind tie-downs, and lateral bracing.
Two-Storey Wall Removals
Managing heavy floor joist and upper-level wall loads with heavy universal steel beams and continuous column load paths down to foundations.
Commercial Tenancy Wall Alterations
Removing or modifying structural masonry, concrete tilt-panels, or steel columns in retail spaces, offices, and hospitality venues.
Is the Wall Load-Bearing?
Professional assessment of truss layout, hanging beams, strutting beams, and wall framing to definitively determine structural load paths.

Wall Removal Structural Engineering FAQs
If the wall is load-bearing, contributes to structural stability, or its role cannot be confidently established, structural engineering is required before the structural support is altered. The engineer determines what the wall supports and designs the required replacement structural system.
Do not rely on appearance alone. The answer depends on roof framing direction, floor systems, walls above, beams, bracing, and foundations. Existing plans may provide useful information, but further investigation may be required where the structural arrangement is uncertain.
A structural wall can often be replaced with an engineered beam and post system, but feasibility depends on loads, span, supporting conditions, and available depth. The existing wall should never be removed until an engineering solution has been designed.
Depending on the project, the replacement system includes a structural beam (steel UB/PFC or engineered LVL), posts or columns, connection brackets, and supporting footings beneath the floor.
Yes, in many cases. A flush or concealed beam depends on existing framing depth, beam span, structural loading, services, and construction constraints. Our engineers design flush ceiling beams whenever head height is a priority.
Not necessarily. The beam ends can sometimes be supported directly by existing structural walls or columns if they have sufficient bearing capacity. The engineer determines the most efficient support configuration.
Possibly. Where a new beam transfers concentrated point loads through posts, the supporting foundation below the floor or slab may need to be assessed or reinforced with localized pad footings.
Not every project automatically requires a site inspection. Where existing architectural drawings, clear photographs, and ceiling access provide sufficient detail, engineering can be completed directly from documentation.
Approval requirements depend on the property and scope. QBCC notes that major structural alterations may require approval from a building certifier, who will assess our Form 15 structural drawings against the National Construction Code.
Send the property address, proposed renovation plan or sketch, photographs of the wall and ceiling space, approximate opening width, and details of any floor or storey above.
Discuss Your Wall Removal Project
Send us the property location, photographs of the wall and any available existing or proposed floor plans. If the wall is below another storey or forms part of a larger renovation, include the relevant architectural drawings.
We will review the available information and determine the structural engineering scope required for your wall removal.
