Perth’s premium renovation market is concentrated in a narrow band of suburbs — the western suburbs, the river frontages and the coastal strip — and it spends differently from Sydney’s or Melbourne’s. Less on heating, insulation and glazing performance. Far more on outdoor living, pools, shading, and the structural work that opening up a masonry house demands.
It is also a market where the underlying construction shapes what is possible. Double brick is durable and thermally sound but unforgiving of improvisation, and premium work in masonry requires the design to be resolved before anything is demolished.
What “High-End” Means in Perth Numbers
- $300,000 to $600,000 — a substantial whole-house renovation with a significant extension, architect-designed, high-quality finishes, custom joinery throughout, and a properly resolved alfresco.
- $600,000 to $1.2 million — comprehensive reconstruction of an existing home, or a large two-storey addition, with specified stone, integrated technology, a pool and landscape design in scope.
- $1.2 million to $3 million — Cottesloe, Dalkeith, Peppermint Grove, Nedlands, City Beach and river-frontage projects: pools, lifts, extensive glazing, basements on sloping sites, bespoke metalwork and stone.
- Above $3 million — a small market of river and ocean frontage properties where the constraint is the site and the local planning controls rather than budget.
Per square metre, high-end Perth renovation runs $6,000 per square metre and above, against $2,200 to $3,000 for budget work and $3,500 to $5,000 mid-range.

Where the Money Goes
Design and consultants — 12 to 20 per cent
- Architect — typically 8 to 15 per cent of construction cost for full services including contract administration
- Interior designer — often separate, at 3 to 8 per cent
- Structural engineer — $8,000 to $40,000, and more where substantial masonry is being removed or a second storey added to double brick
- Geotechnical engineer — for sloping sites, limestone and any basement work
- Town planner — $5,000 to $25,000 where the design departs from the deemed-to-comply provisions of the R-Codes and planning approval is contested
- Heritage consultant — $2,000 to $15,000 where the property is listed or in a heritage area, which affects parts of Cottesloe, Claremont, Subiaco and Fremantle
- Private building surveyor for the certified permit route
- Landscape architect — $10,000 to $60,000, and in Perth’s climate the landscape earns its fee
- Lighting designer — $8,000 to $35,000
- Pool designer and hydraulic consultant on projects with significant water features
On a $1.5 million Perth project the consultant team can exceed $200,000.
Structure and site works
Perth’s ground conditions cut both ways at the premium end.
- Excavation is cheap. Sand is easy to dig, and basements are more affordable in Perth than in Sydney’s sandstone or Melbourne’s clay. This is a genuine local advantage and it is why basements appear more often in Perth premium homes than the market size would suggest.
- Limestone may be encountered below the sand, which changes the excavation economics
- Retaining and shoring — limestone retaining walls are the Perth vernacular, at $10,000 to $20,000 for typical work and considerably more on a steep or deep site
- Masonry removal and structural steel — $8,000 to $18,000 per significant opening, and premium projects frequently involve several
- Second-storey additions to double brick — feasible where footings are adequate, and requiring underpinning where they are not
- Long-span steel for the open-plan interiors and large glazed openings premium work depends on
Openings and the indoor-outdoor connection
Where premium Perth spends what premium Melbourne spends on heating and triple glazing.
- Large stacking and cavity-sliding door systems — $2,000 to $5,000 per square metre
- Structural glass and frameless corner assemblies — $4,500 to $11,000 per square metre
- Motorised and pocket-sliding systems, which let a whole wall disappear into the alfresco
- Retractable insect and weather screening across large openings
- External shading systems — motorised louvres, blinds and screens, which in this climate are functional rather than decorative
- Automated external shutters, which Perth uses more than any other Australian capital
Note what is comparatively modest: glazing thermal performance. In a cooling-dominated climate with intense sun, external shading delivers more than high-specification glass, so premium Perth budgets rarely extend to triple glazing.
Outdoor living, pool and landscape — 15 to 25 per cent
Higher as a proportion than in any capital except Brisbane, and correctly so given the climate.
- Under-main-roof alfresco integrated into the house — $1,800 to $3,200 per square metre
- Outdoor kitchens with stone, integrated appliances and marine-grade cabinetry — $55,000 to $140,000
- Pool, plant, heating and surrounds — $120,000 to $450,000. Pools are close to standard at this level in Perth.
- Waterwise structural planting, irrigation, lighting, limestone walls and screening — $100,000 to $400,000
- Mature tree installation using species that survive Perth summers
Joinery and stone — 15 to 25 per cent
- Custom two-pack joinery — $2,250 to $3,200 per linear metre
- Timber veneer and specialty finishes — $3,000 to $5,200 per linear metre
- Natural stone benchtops and slabs — $1,280 to $3,200 per square metre before fabrication
- Marine-grade specification for anything in or near the outdoor areas
- Jarrah and local hardwoods, which appear more in Perth premium work than elsewhere and read as distinctly Western Australian
A premium Perth kitchen commonly runs $110,000 to $300,000, with an appliance package of $35,000 to $100,000.
Services and technology — 10 to 18 per cent
- Ducted zoned air conditioning with individual room control — $30,000 to $90,000
- Home automation — lighting, blinds, shutters, audio, security, access — $40,000 to $220,000. Automated external shading is a distinctly Perth priority.
- Solar, battery storage and backup power — $25,000 to $80,000, and Perth’s solar resource makes this genuinely productive
- Lifts — $60,000 to $200,000, common on Perth’s sloping coastal and river sites
- Pool plant, heating and automation
- Comprehensive ceiling fan installation, integrated with the automation
- Termite management systems designed into the structure
What Distinguishes a Premium Project
Tolerances and junctions
Mainstream construction works to tolerances measured in millimetres; premium construction works to fractions of a millimetre in visible areas. Shadow lines running true, flush thresholds, consistent reveals, tile and stone joints aligning across a room and continuing up the wall. The design fee is largely the cost of resolving the thousands of junctions where materials meet.
Working in masonry demands resolution before demolition
This is Perth’s particular premium challenge. In a framed house, a wall position can be adjusted on site with relatively little consequence. In double brick, every opening is a structural element with a designed lintel or beam, engineered bearing, and brickwork that has to be cut and made good.
Changing your mind about an opening after the steel is in is genuinely expensive, and improvisation shows. Premium Perth projects succeed on the completeness of the structural documentation more than on any finish selection.
The indoor-outdoor threshold
The signature premium Perth detail. A genuinely flush threshold across a wide opening between an internal floor and an alfresco, with a drainage grate, a correctly detailed upstand beneath the finished level, and waterproofing continuing under the door track.
Perth’s advantage is that winter rain is less intense than Brisbane’s storms, making the detail somewhat more forgiving. The complication is wind-driven sand and the volume of glazing typically involved.

Shading as architecture
At the premium end in Perth, external shading stops being a bolt-on and becomes part of the building’s expression — deep reveals, brise-soleil, automated louvre systems, pergola structures integrated with the roofline, and generous eaves designed for the specific sun angles of the site.
This is where accomplished Perth architecture distinguishes itself from expensive houses imported from an eastern-states design sensibility. A large western glazed wall with no shading, in this city, is a design failure regardless of the glass specification.
Concealment
Premium interiors hide their services. In masonry construction this is harder than in framed work — every concealed run must be chased or bulkheaded and coordinated with the structure. It is another argument for resolving the documentation completely before construction starts.
Perth-Specific Realities at the Top End
- The R-Codes govern. Setbacks, site coverage, boundary walls, overshadowing and privacy provisions apply regardless of budget. Where a design departs from deemed-to-comply, planning approval takes 60 to 90 days and neighbour consultation may follow.
- Local planning policies vary considerably between the western suburbs councils, and several have specific streetscape, bulk and scale provisions for prestige areas.
- Heritage applies in parts of Cottesloe, Claremont, Subiaco, Peppermint Grove and Fremantle.
- Coastal exposure dictates material specification throughout — 316 stainless, marine-grade finishes, and window systems rated for the exposure.
- Sloping sites along the river and the coastal escarpment require substantial retaining and, frequently, lifts.
- Trade availability. Perth’s premium trade pool is small — stonemasons, specialist joiners, structural glazing installers, heritage bricklayers. They are booked well ahead, and during construction booms bricklayer availability alone can drive the programme.
- Freight. Specialty materials come from the eastern states or overseas, adding weeks. Premium projects should lock material selections early and order well in advance.
- Summer heat affects external work scheduling, and premium builders programme masonry and roofing outside the peak.
Contract Models
Premium Perth projects rarely use fixed-price contracts, because the level of unresolved detail and the likelihood of client-driven change make fixed pricing either inaccurate or heavily loaded with risk margin — particularly where masonry is being opened and existing conditions are unknown.
- Fixed price. Certainty, but risk loading of 15 to 25 per cent on a complex masonry project, and unused risk is not returned.
- Cost plus. Transparent, but requires trust and rigorous administration.
- Cost plus with a guaranteed maximum price. The most common arrangement on large Perth projects — open-book costing with a ceiling and a shared-savings mechanism.
- Construction management. Maximum control and transparency; maximum owner exposure.
Whichever model, an independent superintendent or project manager acting for the owner is worth their fee above roughly $1.2 million.
Note that Home Indemnity Insurance remains mandatory above $20,000, and its $200,000 completion limit is a smaller proportion of a premium project — which makes builder due diligence more important rather than less. Verify registration and financial standing carefully at this level.
The Consultant Sequence That Works
- Establish the R-Code coding, local planning policy and any heritage status before the architect produces a resolved design. The approval envelope is the real brief.
- Geotechnical assessment early on any sloping site or where a basement is contemplated.
- Structural engineer alongside the architect, not after — in masonry the structure shapes the architecture more directly than in framed construction.
- Private building surveyor before documentation is complete, to flag compliance while changes are cheap.
- Builder engaged early under an early contractor involvement arrangement, to price and buildability-test the documentation.
- Lock material selections early given freight timelines.
The Long Tail: Finishing and Defects
The final ten per cent routinely takes three to six months — commissioning automation, air conditioning, pool plant and shading systems; seasonal movement in stone, timber and joinery; paint touch-ups; landscape establishment, which in Perth’s sandy soils and water restrictions takes patience; and the long list of small imperfections visible only when the furniture is in.
One Perth note: schedule a formal defects inspection after the first full summer. Sealant failure, shading system performance, cooling capacity and any thermal movement in large glazed assemblies only reveal themselves in a genuine heatwave. Reporting within the defects liability period and the six-year Home Indemnity period matters.
On Overcapitalising
Above roughly $2 million in total property value, Perth renovation spend recovers at perhaps 50 to 80 cents in the dollar unless the property is genuinely under-improved for its location.
The exceptions are properties with an exceptional attribute — an ocean or river outlook, a north-facing rear on a prestige street, a genuinely large block in the western suburbs — where a renovation that finally realises that attribute can be transformative. A Cottesloe house that ignores its aspect is worth substantially less than the same house reoriented to it, and closing that gap is the strongest case for premium spending in this city.

Where Premium Perth Projects Actually Go Wrong
Three failure modes recur at this level, and none are about money.
Design changes after the steel is in. In masonry, every opening is a structural element with a designed beam and engineered bearing. Moving an opening after construction has started means re-engineering, re-propping and rebuilding brickwork — and it shows in the finished work. Premium Perth projects succeed on the completeness of the structural documentation more than on any material selection.
Western glazing without a shading strategy. A large west-facing glazed wall in Perth, however good the glass, produces a room that is unusable on a February afternoon and expensive to cool. At premium level this is a design failure rather than a budget one, and it is the clearest sign of an eastern-states design sensibility applied without adaptation.
Approval discovered late. A design resolved to a high level and then tested against the R-Codes for the first time will often need amendment. On a premium project that redesign can cost $80,000 in fees before the 60-to-90-day planning approval delay is counted.
Documentation at This Level
The largest difference between a premium project and an expensive one is the drawing set. On a substantial Perth project the documentation runs to hundreds of sheets: plans and elevations, but also structural details for every opening, joinery details at 1:5, junction details for every material transition, setting-out drawings for tiling and stone, reflected ceiling plans coordinating lighting, fans and services with structure, threshold and waterproofing details at every opening to the alfresco, shading geometry for each elevation, and a finishes schedule specifying every product by name and code.
In masonry construction this matters more than in framed work, because anything undocumented becomes an on-site decision that cannot easily be reversed.
Prestige Suburb Realities
- Coastal exposure in Cottesloe, City Beach and the northern coastal strip dictates specification throughout — 316 stainless, marine-grade window systems, and coating grades rated for the exposure.
- Sloping river and coastal sites require substantial limestone retaining and frequently a lift.
- Local planning policies vary considerably between the western suburbs councils, several of which have specific bulk, scale and streetscape provisions for prestige areas.
- Neighbour management. Adjoining owners in these suburbs are well resourced and well advised. Dilapidation reports, agreed working hours and proactive communication are essential.
- Site access. Narrow streets and mature verge trees restrict crane positions in the older western suburbs.
- Trade availability. Perth’s premium trade pool is small, and during construction booms bricklayer availability alone can drive the programme.
- Freight. Lock material selections early; specialty stone, tapware and fittings come from the eastern states or overseas.
