Common Mistakes When Removing Interior Walls (and How to Avoid Them)

Wall Removal vs Extension: Which Is More Cost-Effective in Perth?

If you’re planning kitchen renovations in Perth WA, the first question is almost always cost. The honest answer is that it depends more on your choices than most quotes let on.

Cabinetry alone can swing a budget by tens of thousands of dollars. Where your plumbing sits can make or break a timeline.

Here’s what actually shapes a Perth kitchen renovation in 2026, from price bands to the process itself, plus the mistakes worth avoiding along the way.

What Kitchen Renovations Cost in Perth Right Now

Perth kitchen renovation costs generally fall into three bands:

Renovation Type	Typical Cost	What’s Included
Cosmetic refresh	$8,000–$20,000	New benchtops, cabinet fronts, splashback and hardware, existing layout and plumbing kept in place
Mid-range full renovation	$25,000–$45,000	New cabinetry, layout tweaks, upgraded appliances and finishes
Premium or custom kitchen	$45,000–$80,000+	Full custom joinery, high-end appliances, and often structural or plumbing changes

Perth-specific factors push these figures higher than the national average, since freight on imported fittings and a trades market that’s often pulled toward mining work both add to the bill.

The biggest cost driver isn’t the kitchen itself but the plumbing. Moving a sink, dishwasher, or gas line means new pipework and often reworking the slab, which can add several thousand dollars before a single cabinet goes in. If your new layout keeps plumbing points where they already are, you’ll save significantly.

Cabinetry usually makes up 30–40% of the total budget, so it’s the line item worth spending the most time comparing. Benchtops, splashbacks, and appliances typically make up the rest, roughly split between materials and labour. If a bathroom is also on your radar, the same cost logic applies there too. It’s worth a look at our bathroom renovations guide for how those numbers break down.

What Drives the Cost Beyond Cabinetry

A few less obvious factors regularly move a Perth kitchen quote up or down:

Layout changes. Keeping the kitchen’s footprint the same is far cheaper than reconfiguring it, since moving a wall, changing the “work triangle” between sink, stove, and fridge, or opening the kitchen into a living area all add trades and time.
Electrical upgrades. Older Perth homes, especially character properties in suburbs like Fremantle or Mount Lawley, often have wiring that doesn’t meet current standards for the appliance load a modern kitchen needs, so it’s worth budgeting for an electrician’s assessment early rather than finding out mid-build.
Ventilation and rangehood ducting. Where the rangehood needs to vent externally, running new ducting through a roof cavity or wall can add to the cost, depending on the home’s construction.
Access and site conditions. Two-storey homes, narrow side access, or heritage-listed properties can all add labour time that a flat, easy-access block wouldn’t need.

A Note on Benchtops

Engineered stone containing crystalline silica was banned across Australia from July 2024 on health grounds.

For Perth kitchens, that’s shifted benchtop choices toward three main alternatives, all of which also hold up well against WA’s climate and light exposure:

Sintered stone. A popular mid-to-premium choice thanks to its heat and scratch resistance.
Porcelain. A lighter-weight, budget-friendly option with a similar look to stone.
Natural stone (granite or marble). The premium option for homeowners after a specific look, with more variation in maintenance requirements.

The Kitchen Renovation Process, Step by Step

Consultation. A look at your existing layout, budget, and how your household actually uses the kitchen. This is also the time to flag any known issues, such as old wiring, past water damage, or plumbing you suspect needs updating.
Design & planning. Layout and material decisions get locked in, with a realistic timeframe set before work starts. This stage should also cover council requirements: most cosmetic kitchen updates don’t need approval in WA, but structural changes, such as removing a load-bearing wall or altering plumbing stacks, usually do.
Build & installation. Licensed trades handle electrical, plumbing, and cabinetry installation, with clear updates as work progresses. You can read more about who we work with and how we vet trades if that’s useful context before committing. Expect the build to run in a rough order: demolition, then rough-in electrical and plumbing, then cabinetry installation, benchtops, splashback, and finally the fit-off of appliances and fixtures.
Final handover. The finished kitchen is checked against the original brief before sign-off, including confirmation that all trades have signed off their work for warranty purposes.

How Long Does It Take?

A cosmetic refresh can be done in as little as one to two weeks. A full mid-range renovation typically runs four to eight weeks once cabinetry is factored in, since custom joinery has longer lead times than off-the-shelf options and is worth locking in early if you’re on a deadline. Premium or fully custom kitchens, particularly where layout changes or structural work are involved, can extend to three months or more once design time, approvals, and lead times on imported fittings are added in.

It’s worth planning your cooking arrangements for the build period, too. Most households manage with a temporary setup, such as a microwave, kettle, and bar fridge in another room, for anywhere from two to six weeks, depending on scope.

Avoiding the Common Pitfalls

A few habits separate a smooth renovation from a stressful one:

Lock in appliances before cabinetry is designed. Appliance dimensions should be finalised before cabinetry is built, not after, since retrofitting a fridge or oven that doesn’t match the allocated space is a common and avoidable cost.
Prioritise storage as much as finishes. It’s easy to focus on benchtop space and finishes over storage, then regret it within the first few months of living with the new kitchen.
Compare quotes on the same basis. A cheaper quote is sometimes a cheaper build, so ask for cabinetry, benchtops, appliances, and labour broken out separately when comparing.
Build in a contingency. Older Perth homes, particularly character properties, can reveal wiring or plumbing issues once cabinetry comes out, so a small contingency (around 10% is a common rule of thumb) helps avoid the project stalling mid-way.
Consider a hybrid approach. Semi-custom cabinetry with a few bespoke elements, like an island or a feature pantry, often gets close to a fully custom look for meaningfully less than a fully bespoke build.

Frequently Asked Questions

Do I need council approval for a kitchen renovation in Perth?

Cosmetic updates, such as new cabinetry, benchtops, and appliances within the existing footprint, generally don’t require approval. Structural changes, such as removing a load-bearing wall or relocating plumbing stacks, usually do. Your renovation team should flag this during the planning stage.

Can I stay in my home during a kitchen renovation?

Most homeowners do, with a temporary kitchen setup elsewhere in the house for the build period. Full house transformations or extensive layout changes may make it more practical to arrange alternative accommodation for part of the build.

What adds the most value to a Perth kitchen renovation?

Quality cabinetry and a functional layout tend to matter more for resale value than premium finishes. A kitchen that works well for how the space is actually used generally outperforms one chosen purely for how it photographs.
