Considering house extensions in Perth to create a bigger kitchen, add a scullery, upgrade your laundry or refresh bathrooms and wardrobes? Joyce Kitchens designs and delivers custom cabinetry and practical layouts that make extensions feel seamless with your existing home.
House Extensions Perth: Why extend instead of moving?
Perth families are choosing home extensions to unlock open‑plan living, an entertainer’s kitchen, and extra storage without leaving their suburb. A considered extension can add value, improve energy efficiency and deliver the custom kitchen, bathroom and laundry spaces you’ve always wanted.
- Open up a cramped galley kitchen into an airy U‑shaped kitchen with island and breakfast bar.
- Add a scullery or butler’s pantry for prep, storage and small appliances.
- Connect the kitchen to an alfresco kitchen for WA’s indoor‑outdoor lifestyle.
- Upgrade wardrobes and robe fit‑outs to maximise bedroom storage.
Searching “home extensions near me” or “renovations and extensions Perth”? Joyce Kitchens brings design, custom cabinetry and installation together for a smooth, well‑managed project.
Core design insights for WA homes
Light, heat and coastal conditions
Perth’s sun and sea breeze shape the way we design. We balance north light with shading, specify UV‑resistant finishes, and choose corrosion‑resistant hardware near the coast. For benchtops in high‑heat or alfresco zones, we recommend porcelain or sintered stone for better heat tolerance.
Local standards and approvals
Most structural house extensions require council approval and compliance with the NCC (Building Code of Australia) and relevant AS/NZS standards. We coordinate with your builder, engineer and certifier to ensure cabinetry, services and appliances align with the approved plans.
- Electrical and appliance clearances in line with AS/NZS 3000 (wiring rules).
- Gas cooktop and rangehood installation in line with AS/NZS 5601 and manufacturer specs.
- Ventilated sculleries and compliant ducted rangehoods for best performance.

Our extension and renovation process
1) In‑home or showroom consultation
We discuss how you live, your wish‑list, appliances and budget. Bring plans or we can measure on site.
2) Concept design and layout options
You’ll see options for an L‑shaped kitchen, U‑shape with island, or galley kitchen, plus scullery/utility zones, laundry renovation ideas and wardrobe layouts. We consider sightlines, task zoning and traffic flow for true open‑plan living.
3) Selections: materials, colours and appliances
Choose from custom cabinetry WA‑made by Joyce: melamine, thermolaminate, vinyl wrap, and 2‑pack polyurethane doors; benchtops in laminate, timber, porcelain or sintered stone; splashbacks from toughened glass to porcelain slabs and subway tiles. We plan for 600 mm and 900 mm Australian appliance sizes, integrated fridges and induction cooktops.
4) Documentation and coordination
We produce detailed drawings, service plans and cabinetry schedules to coordinate with your builder’s extension works and any engineering or council requirements.
5) Manufacturing and installation
Your custom cabinetry is manufactured locally for quality control and shorter lead times. Then our installers fit soft‑close drawers, pull‑out pantries, appliance garages and integrated bins, aligning with your builder’s program.
6) Handover and care
You’ll receive care guides for benchtops and finishes, plus warranty information.
Materials and finishes for Perth homes
Choosing the right mix of durability, maintenance and style is key for kitchens, laundries and bathrooms. Below is a quick comparison of popular benchtop options.
Comparison: Engineered Stone vs Laminate Benchtops
| Feature | Engineered Stone* | Laminate |
|---|---|---|
| Look and feel | Stone‑like appearance, consistent patterns, potential waterfall edge | Wide range of designs, realistic stone/timber looks at a lower cost |
| Heat resistance | Moderate; avoid direct hot pots | Moderate; use trivets to prevent scorch marks |
| Scratch/impact | Good scratch resistance, can chip on edges | Good everyday performance; edges can be vulnerable to impact |
| Maintenance | Low; wipe clean, avoid harsh chemicals | Low; wipe clean, avoid standing water on seams |
| Indicative cost (installed) | $$$ | $ to $$ |
| Regulatory note in WA | Subject to current Australian restrictions; alternatives include porcelain or sintered stone | No special restrictions; great budget option |
*Engineered stone usage in Australia is subject to recent regulatory changes. Confirm current requirements with your builder and check guidance via HIA or WorkSafe resources. Many Perth renovators now choose porcelain or sintered stone for high heat and outdoor‑adjacent areas.
Cabinet doors and hardware
- Shaker kitchen profiles in 2‑pack polyurethane for timeless style.
- Handleless and finger‑pull designs for a sleek modern look.
- Soft‑close drawers, pull‑outs and corner solutions to maximise storage.
- Moisture‑resistant boards for laundries and bathroom vanities.
Appliances and services
We plan ventilation for ducted rangehoods, allow power for integrated dishwashers, and provide splashback clearance for gas or induction. In older character homes, we coordinate service upgrades with your builder and licensed trades.
Layouts and styles that work in extensions
Open‑plan kitchens with islands
Islands create a natural hub with space for entertaining and casual meals. Include a breakfast bar, integrated bins and a concealed appliance garage to keep benches clear.
Scullery or utility room
A scullery behind the kitchen or along the side can host a second sink, dishwasher and open shelving for bulk goods. It’s perfect for Perth entertaining and keeps the main kitchen display‑ready.
Laundry and mudroom links
Combine the extension with a laundry renovation and mudroom storage. Durable, easy‑clean finishes and smart hanging space make family life easier.
Style directions
- Coastal contemporary: light timbers, white 2‑pack, matte black hardware, and porcelain splashbacks.
- Modern shaker: classic profiles with stone‑look benchtops and subway tiles.
- Urban minimal: flat‑front doors, integrated fridge, induction cooktop and concealed rangehood.
Costs and budgets for Perth extensions and kitchens
Every project is unique, but these planning ranges can help set expectations. Your final price depends on size, structural works, selections and appliances.
- Kitchen extension + custom cabinetry: from approximately $35,000–$90,000+ (cabinetry, benchtops, splashbacks, hardware; excludes major structural works).
- Scullery addition: from approximately $12,000–$35,000+ depending on size and appliance set‑up.

We’ll help stage works to suit your budget—e.g., prioritise cabinetry and benchtops now, add a butler’s pantry later.
Key cost drivers

- Benchtop material (laminate vs porcelain/sintered stone) and splashback type.
- Door finish (melamine vs 2‑pack polyurethane) and internal hardware.

WA extension + kitchen renovation checklist
- Define your goals: larger kitchen, scullery, laundry, alfresco connection, storage.
- Confirm planning pathway with your builder/certifier and council.
- Decide on layout: L‑shape, U‑shape with island, or galley with scullery.
- Lock in appliance sizes early (600/900 mm ovens, integrated fridge, rangehood ducting).
- Choose finishes fit for WA: UV‑resistant doors, heat‑tolerant benchtops near sliders or alfresco.
- Consider acoustics in open‑plan spaces (pantry doors, soft furnishings, underlay).
- Set a realistic budget and contingency (typically 10–15%).
- Schedule around lead times for custom cabinetry and benchtops.
Short WA case‑style examples
Nedlands: Period home, modern shaker kitchen
A rear house extension opened a 1920s home to the garden. Joyce specified a modern shaker kitchen in 2‑pack polyurethane, porcelain benchtops, a ducted rangehood and a compact scullery with open shelving. The island added a four‑seat breakfast bar while keeping clear walkways.
Fremantle: Coastal duplex with galley and alfresco
In a narrow block, we designed a streamlined galley kitchen with an appliance garage and integrated fridge, linking to an alfresco kitchen. Sintered stone benchtops delivered superior heat and UV resistance for summer entertaining.

FAQ
How much does a house extension with a new kitchen cost in Perth?
As a planning guide, a custom kitchen extension fit‑out can range from about $35,000–$90,000+ depending on size, materials and appliances. Whole‑of‑house extensions managed by your builder can range from around $2,500–$4,500 per m² for the structure, with kitchen, bathroom and wardrobe fit‑outs additional. We’ll tailor a proposal after measuring and confirming your selections.
Do I need council approval for a kitchen extension in WA?
If your works change the building footprint or structure, you’ll usually need approval via your local council or a private certifier. Your builder coordinates engineering, energy reports and certification under the NCC, while we supply detailed cabinetry and services drawings to match. For guidance, check WA Building and Energy’s information on the building approval process.
What benchtops suit Perth heat and alfresco‑adjacent kitchens?
For high heat, UV and outdoor‑adjacent zones, porcelain or sintered stone offers excellent heat and UV resistance. Laminate remains a great budget choice indoors when paired with good heat practice (trivets). Engineered stone is subject to current Australian restrictions—speak with us about compliant options for your project.
How long does a kitchen renovation and extension take?
Design and selections typically take 2–6 weeks depending on complexity. Custom manufacturing and installation generally take 4–10 weeks from final sign‑off. If your builder is completing structural works, we coordinate dates so services, flooring and benchtop templates align with the build program.
Can Joyce Kitchens help with bathrooms, laundries and wardrobes too?
Yes. We design and manufacture custom vanities, laundry joinery and built‑in wardrobes alongside your kitchen, so the whole home feels cohesive. One team handles measurements, drawings, selections and installation across all spaces.
