Removing Internal Wall: What To Think About

Removing an internal wall can transform the way your home feels. A separate kitchen and dining room can become one connected space, a narrow living area can open up, and natural light can reach further into the house. It can be a worthy renovation.

But taking out a wall involves more than demolition. The structure above it, services inside it and finishes around it all affect what is possible, how much work is involved and what the completed renovation will look like.

At Skyline Concepts, our Perth carpenters understand how much difference a well-planned layout change can make. Our advice is to assess the whole project before starting: the wall itself, the support it may provide and the work needed to finish the space properly.

If you are thinking about removing an internal wall in your Perth home, here are the main things to consider.

Can You Remove An Internal Wall?

Many internal walls can be removed or altered, but only after their role has been assessed. Some divide rooms without supporting the building above; others carry structural loads or contribute to stability.

A structural wall may be removable with a properly engineered replacement support system. A non-structural wall can still contain electrical wiring, plumbing or other services that need professional attention.

The first question is whether the proposed change can be made safely and appropriately in your particular home.

Be Clear About Why You Want To Remove The Wall

Before arranging assessments or quotes, decide what you want the change to achieve.

Common reasons include:

• Connecting the kitchen, dining and living areas.
• Improving circulation through the home.
• Creating a larger entertaining space.
• Bringing more natural light into adjoining rooms.
• Improving sightlines between family spaces.
• Making an older layout suit modern living.

Think about the room after the wall is gone. Where will the sofa go? Will you lose useful kitchen cabinetry? Will there still be somewhere for the television, storage and power points?

At Skyline Concepts, we recommend planning the furniture and everyday use of the space first. An opening should improve how your home works, rather than simply make it look larger.

Is The Wall Load-Bearing?

A load-bearing wall supports weight from parts of the building above it. Depending on the construction, that might include roof framing, ceiling structures or an upper floor.

Removing that support without a designed alternative can cause serious structural damage or collapse.

How Can You Tell?

Wall position, construction type and the direction of framing can provide clues, but they are not reliable confirmation on their own.

A timber stud wall can be load-bearing. A masonry wall is not automatically load-bearing. An apparently simple partition may also contribute to bracing or support ceiling elements.

Original drawings can help, but previous renovations may have changed the structure. The existing building needs to be checked against any available plans.

Do not decide a wall is safe to remove by tapping it, measuring its thickness or looking at one photograph. Have its structural role assessed by an appropriately qualified professional, with a structural engineer involved where required.

What About Bracing Walls?

Some walls help resist sideways forces and keep the building stable. These can matter even if they do not carry significant vertical loads.

The assessment should consider both support and stability, rather than stopping at whether the wall is “load-bearing”.

Will You Need A Beam, Posts Or New Footings?

Where a wall provides structural support, the engineer may design a beam or another system to replace it.

That design needs to account for the loads, opening width, connections, supports and existing construction.

A Beam Needs Something To Sit On

A beam transfers loads to its ends. Those loads may require posts, suitable bearing areas or strengthened foundations.

An existing floor slab or remaining wall cannot automatically be assumed capable of carrying the new concentrated loads.

This is why a structural alteration involves more than choosing a beam that spans the opening. The whole load path must work.

Will The Beam Be Visible?

Some designs leave a beam below the ceiling, creating a bulkhead. Others may allow it to be incorporated into the ceiling or roof space.

A concealed beam is not always feasible and may involve more work. Roof access, framing, services and available depth can all affect the options.

Ask about the finished appearance early. A wide opening with a bulkhead and posts may look quite different from the completely flush ceiling you imagined.

Do You Need Approval To Remove An Internal Wall In Perth?

Approval requirements depend on the proposed work and the property. In Western Australia, structural alterations commonly require a building permit and supporting documentation.

An internal location does not automatically make the work exempt. Do not assume that a non-load-bearing wall can be removed without checking whether an exemption applies.

Before starting, confirm requirements with your local government’s building team or an appropriately qualified building surveyor. Ask whether the scope requires:

• A building permit.
• A demolition permit.
• Engineering documentation.
• Planning approval or heritage consent.
• Other property-specific permissions.

Building approval and planning approval serve different purposes. Your project may need one, both or neither, depending on the applicable requirements.

Strata, Shared And Heritage Properties

Apartments, townhouses and strata properties may have additional consent requirements. A wall can affect common property, shared services, fire separation or acoustic performance.

Heritage listings and other restrictions can also affect internal changes.

Obtain the relevant permissions before work begins. Approval from a contractor does not replace consent from the authority or property body responsible.

What Is Inside The Wall?

A wall can contain services even when there are no visible outlets or taps on its face.

Possible services include:

• Electrical wiring and power points.
• Lighting circuits and switches.
• Water supply pipes.
• Drainage or vent pipes.
• Gas pipework.
• Data and communication cables.
• Air-conditioning services.

Moving them may affect more than the immediate opening. A switch might need relocating to another wall, or pipework may need a new route through the ceiling or floor.

Our Skyline Concepts team recommends including service changes in the scope from the start. They can influence both the budget and the finished layout.

Who Should Handle Service Changes?

Electrical work must be handled by the appropriately licensed electrician. Plumbing and gas work should be carried out by appropriately licensed trades for the relevant scope.

Services need to be identified and made safe before demolition. Switching off a light or avoiding a visible power point does not confirm that a wall is clear of live wiring.

Could There Be Asbestos Or Other Hazardous Materials?

Older homes may contain asbestos in wall linings, backing materials, textured finishes or nearby flooring. Homes built or renovated before 1990 deserve particular attention.

You cannot reliably identify asbestos by appearance. If suspect materials may be disturbed, arrange professional assessment and testing before work begins.

Old paint may also contain lead. Cutting masonry and other materials can generate hazardous dust, including respirable crystalline silica.

Material identification, removal methods and dust controls should be planned before demolition starts. An ordinary household vacuum and an open window are not an adequate dust-management plan.

Temporary Support And The Order Of Work Matter

Structural wall removal may require temporary support while the permanent replacement is installed.

The temporary works and removal sequence need competent planning appropriate to the design and site. Supports also need suitable foundations or bearing surfaces beneath them.

Do not attempt to work out prop positions, beam sizes or the demolition sequence from a generic online guide.

Your contractor should explain how the work will be organised, who is responsible for the structural design and which inspections or checks are required.

What Happens To The Floor?

The wall may have been built before the floor covering was installed. Once it is removed, you may find a strip of bare substrate where it stood.

The two adjoining rooms may also have different floor finishes, levels or installation histories.

Can The Existing Floor Be Patched?

Sometimes, but it depends on the material and installation.

Tiles may be discontinued. Timber may have changed colour with age. Floating flooring may need sections lifted and relaid, rather than a narrow strip inserted.

Even spare materials can look different from the existing finish.

At Skyline Concepts, we recommend deciding on the flooring solution before demolition. This helps you budget for the finished room and avoid an obvious join where the wall used to be.

What If The Floor Levels Differ?

Different levels may require levelling work or a suitable transition. Check how any change affects nearby doors, cabinetry and access.

Structural support work may also disturb the floor locally, adding to the repair scope.

What Happens To The Ceiling And Walls?

Removing a wall leaves more than a floor gap.

The ceiling may need patching where the wall connected. Remaining wall ends may need lining, plastering and new corners. Cornices and skirting may need replacing or matching.

If adjoining rooms have different ceiling heights or finishes, the transition needs a deliberate design.

Allow for:

• Ceiling and wall repairs.
• Beam or post linings.
• Cornice replacement or transitions.
• Skirting and architrave work.
• Surface preparation.
• Painting.

Painting only the repaired strip may leave a visible difference in colour or sheen. Repainting a larger surface may produce a more consistent result.

Our carpenters pay attention to these junctions because they affect whether the change feels integrated with the home.

Will Open-Plan Living Suit Your Household?

An open layout has benefits, but it changes how rooms behave.

Noise And Privacy

Cooking noise, conversations and television sound can travel more freely. Consider whether someone needs a quiet place to work, study or relax.

Heating And Cooling

Combining rooms creates a larger space to condition. Existing air-conditioning may need review, including unit capacity and airflow.

Storage And Furniture

Removing a wall can mean losing cupboards, shelving or a useful furniture position. Plan replacement storage before committing.

Cooking Smells And Ventilation

Opening a kitchen to a living area can spread cooking smells further. Review extraction and ventilation as part of the layout.

A partial opening or retained section of wall may provide a better balance for some homes.

How Much Does Removing An Internal Wall Cost?

There is no useful single price without assessing the wall and the full scope.

A straightforward partition removal can be very different from a structural alteration requiring engineering, permits, steelwork, posts, foundation work and service relocation.

The main cost factors include:

• Wall size and construction.
• Structural and bracing requirements.
• Engineering and approval work.
• Hazardous-material assessment or removal.
• Access and temporary support.
• Service isolation and relocation.
• Waste handling and disposal.
• Flooring, ceiling and wall repairs.
• Carpentry, plastering and painting.

Ask whether the quote covers a finished space or only removal. Comparing those two scopes as if they were equivalent can give a misleading picture.

Agree how unexpected conditions and variations will be handled, and keep an appropriate contingency for concealed issues.

How Long Does It Take?

The visible removal may be relatively brief, but the overall project can take longer.

Assessment, design, approvals and trade scheduling happen before demolition. Afterwards, support installation, inspections, repairs, drying times and painting can extend the programme.

Ask for a timeframe covering the whole project, including when the room will be usable again.

If you will remain in the home, discuss dust separation, access, kitchen availability and any interruption to power or water.

Questions To Ask Before Accepting A Quote

Before committing, ask:

• Has the wall’s structural and bracing role been assessed?
• Who will provide engineering if required?
• Who is confirming and obtaining approvals?
• Are hazardous materials and hidden services included in the assessment?
• What will the finished opening look like?
• Will there be visible posts or a bulkhead?
• Does the quote include flooring, plastering, trim and painting?
• Who will coordinate the specialist trades?
• How will the rest of the home be protected?
• What happens if concealed problems are discovered?
• What completion documents will I receive?

Check the contractor’s relevant registrations, licences and insurance for the proposed scope. Keep approved drawings, engineering details and completion documentation with your property records.

Frequently Asked Questions

Can A Carpenter Remove An Internal Wall?

A carpenter may carry out appropriate parts of a wall alteration, but the project can also require engineering, a suitably registered building contractor and licensed specialist trades. The team must suit the actual scope.

Can You Remove A Load-Bearing Wall?

Often it is possible with an engineered replacement support system. Feasibility depends on the building, loads, opening and available support conditions.

Does A Non-Load-Bearing Wall Need A Beam?

Not necessarily. However, its full role must be assessed, including bracing, ceiling support and connections, before deciding what work is needed.

Can You Remove Just Part Of A Wall?

Yes, a wider doorway or partial opening may be an option. It still needs structural, service and approval checks appropriate to the proposed work.

Will Removing A Wall Add Value?

It may improve the home’s appeal if it creates a more functional layout, but added value is not guaranteed. Losing useful storage, privacy or a bedroom can reduce the benefit.

Can I Remove The Wall Myself?

Do not start demolition before the wall, services, materials and approval requirements have been assessed. Structural alterations and specialist work need the appropriate professionals.
