What Designed Work Actually Means on a Wall

There is no product you can buy called architectural cladding. What separates a designed facade from ordinary wall covering is that every visible line on it was decided in advance and the installer was given a drawing showing where it goes. Joint positions land where the architect wanted them, the module resolves against window heads and sills, corners are mitred or returned rather than trimmed, and the shadow gaps are the same width at the top of the wall as at the bottom. Ordinary cladding hides its junctions behind cover strips. Designed cladding shows them deliberately, which means every one of them has to be right.

That single difference explains most of the cost and all of the risk. Nothing is forgiving on a wall where the joints are the pattern, so the framing behind has to be straighter, the set out has to be resolved before ordering, and the flashings have to work while remaining invisible. A tradesperson used to lapped weatherboards can produce excellent work and still make a poor job of an expressed joint facade, because the tolerances are different by an order of magnitude. Ask what designed facades an installer has completed and ask to see photographs of the corners rather than the elevations. Corners are where the skill shows.

Victorian projects of this kind usually arrive with an architect already engaged and drawings already produced, which changes the conversation. The material is chosen, the joints are located, and what an installer is being asked for is a price to build what has been drawn along with an opinion on whether it can be built as drawn. That second part is genuinely valuable and worth inviting. Experienced facade installers routinely spot a junction that will leak, a batten spacing that cannot be fixed to anything, or a corner detail that needs a purpose made flashing nobody has drawn yet. Raising those things at quoting stage is cheap and raising them at installation stage is not.

Owners without an architect can still get designed work, and the honest answer is that the drawing has to come from somewhere. Some cladding installers produce their own shop drawings for a fee, some suppliers provide standard detail sets for their systems that a competent builder can work from, and some jobs are simple enough that a single elevation drawing settles it. What does not work is describing the intent verbally and hoping it is understood. The exterior wall cladding page covers the more conventional systems where that level of documentation is not necessary.

The other thing worth understanding before spending money is that designed facades are judged at close range. A conventional wall is read from the footpath, where a five millimetre discrepancy disappears. A facade with expressed joints is read from a metre away by everybody who walks to the front door, and by the owner every day for twenty years. That is why the standard of finish matters more than on any other cladding work, and why the cheapest quote on a designed elevation is almost never the right one.

The Victorian Palette

Expressed joint fibre cement is the workhorse of designed facades in this state and it earns that position honestly. Sheets in 2400 or 3000 millimetre lengths are fixed to a batten grid with a deliberate gap between them, the gap backed by a black jointing strip or a folded flashing so the shadow reads as a line rather than a hole. It takes paint well, it does not move enough to open the joints, it is non combustible under the criteria the Australian Building Codes Board sets out and it costs a fraction of the metal alternatives. Cemintel and James Hardie both make systems with published details, and working within a published system is considerably safer than inventing a junction. Expect $185 to $360 a square metre installed.

Timber carries most of the warmth in the Victorian palette and it comes from closer to home than people assume. Victorian ash from the Heyfield and Gippsland mills, silvertop ash, messmate and spotted gum all appear on local facades, either as vertical batten screens or as horizontal boards lapped with a deliberate shadow gap between them. Radial sawn boards out of Gippsland have become a recognisable regional product in their own right. The trade off is maintenance, because every timber facade in Melbourne is on a coating cycle whether the owner planned one or not. There is more on fixing and matching on the timber cladding fitting page.

Metal divides into three price brackets and three quite different conversations. Prefinished aluminium and steel systems sit at the affordable end and are covered on the aluminium cladding page. Zinc sits at the top, a material that will outlast the building and develop a soft grey patina while doing it, and it needs an installer who works in zinc rather than one willing to try. Weathering steel sits between them and behaves unlike anything else here, since the finish is the corrosion and it keeps developing for years. Owners who understand that going in are pleased with it and owners who do not are rarely pleased at all.

Masonry has quietly returned to the designed palette across Melbourne and it is worth including. Recycled red brick on a rear extension, glazed brick in a feature panel, brick slips on a lightweight frame and thin stone veneers all appear on architect designed work through the inner suburbs. The look is deliberately at odds with the lightweight material around it, which is exactly the point. Details on the lightweight applications sit on the brick cladding systems page, and the finish coats that often go over them on the render and texture coating page. Masonry doing structural work rather than sitting as a skin is a bricklaying job rather than a cladding one.

Mixing three or four of these on one building is normal and it is where designed work either succeeds or falls apart. A facade combining charred timber, expressed joint sheet and a zinc parapet has three material junctions, and each one needs a detail showing how water gets out and how the two materials terminate against each other. Those details are the thing being bought, more than the material is. Without them the installer improvises, and improvised junctions are where every facade leak in Victoria begins.

Charred and Oiled Timber in a Melbourne Climate

Charred timber has gone from novelty to standard on Victorian architect designed work in about a decade. The process burns the surface deliberately, which drives out some of the moisture and sugars in the outer layer and leaves a black textured face that is more dimensionally stable and less appetising to insects than raw board. Australian producers now supply it commercially rather than it being a site operation, and the finish ranges from a light scorch that reads brown to a deep alligatored black. It photographs extremely well, which is part of why it spread so fast.

What owners are less often told is that the surface still needs a coating and the coating still needs renewal. Charring is not a finish on its own in an exposed position, and a charred wall left bare will grey and chalk like any other timber, losing the depth that justified the cost. Most suppliers specify an oil or a penetrating coating and a renewal cycle measured in a few years rather than a decade. Skipping that cycle for six years and then trying to restore the appearance is a considerably bigger job than maintaining it. Ask what the coating is and how often it goes back on before the material is ordered.

Oiled hardwood battens raise a problem that is specific to this latitude and it surprises people every time. A north or west elevation in Melbourne takes enough ultraviolet to break down an oil finish within a couple of years, while the south wall of the same house, shaded and damp for much of winter, holds its finish far longer but grows mould instead. Recoat both walls on the same schedule and one is always wrong. The practical answer is to accept differential weathering as part of the material, or to coat the exposed elevations more often, or to choose a different material on the worst wall. All three are legitimate and the first one costs nothing. What does not work is expecting a single annual visit to keep every elevation looking the same.

Mould on shaded timber is the complaint Melbourne installers hear most about facade timber. It is cosmetic rather than structural, it responds to washing, and it returns because the conditions that produced it have not changed. A south or southeast facing timber wall tucked behind a fence or under a neighbouring canopy means the honest advice is that it will need washing annually and that this is not a defect. Owners who want no maintenance at all are better served by a prefinished metal or a painted sheet. Nobody should discover that trade off after the wall is up.

Bushfire ratings constrain timber more than any other part of the palette and the constraint tightens quickly. At the lower attack levels a range of species and treated products are acceptable, while at the higher levels most timber is out and the tested alternatives are limited. Properties through the hill and range districts around Melbourne and across much of the peri urban fringe carry ratings that make this decisive. The Country Fire Authority sets out what the construction requirements involve. Settle the rating before the palette, because a beautiful timber facade that cannot be approved is an expensive lesson.

Detailing timber for longevity is unglamorous and it is what separates a facade that ages well from one that fails at the bottom. End grain sealed on every cut, a drained and ventilated cavity behind the boards or battens, a generous clearance above paving or soil, and stainless or hot dipped fixings that will not bleed into the timber. Not one of those items costs much while the wall is open. Not one of them can be added later without taking the wall apart, which is the recurring theme of every page in this series.

Zinc, Copper and Weathering Steel

Zinc is the premium option on a Victorian facade and the price reflects genuine difference rather than branding. Sheet is folded and seamed on site by installers trained in the material, the finish develops a stable grey carbonate patina over several years, and the service life is measured in generations rather than decades. VM Zinc is the name most specified here and the system details are published and well supported. Fitted it is $420 to $780 a square metre, and the number of installers in Victoria genuinely competent in it is small. Ask for completed work and speak to the owners of it.

Copper appears less often and behaves similarly, folding and seaming like zinc and developing its own patina from bright metal through brown to green over many years. It costs more again, it is used mostly in small feature areas on houses, and its runoff will stain anything pale beneath it during the early years. Both metals are also incompatible with aluminium and with plain steel in contact, so the fixings and any adjoining material need thinking about. That compatibility question is the one most often missed on mixed material facades.

Weathering steel is the material that generates the most unhappy phone calls in Victoria and almost always for the same reason. The finish is the rust, and the point of the alloy is that the oxide layer stabilises and protects the steel rather than continuing to eat it. Getting there takes cycles of wetting and drying over a period of months to years, and during that period the surface sheds iron oxide in the runoff. A pale concrete path, a light coloured paver or a rendered plinth underneath a weathering steel wall will stain, and getting that mark out afterwards is close to impossible. Owners discover this in the first autumn after installation, by which time the detail that would have prevented it is behind the steel.

Melbourne makes this slower and more visible than a dry inland climate does. The alloy stabilises through repeated wet and dry cycling, and a Melbourne winter delivers walls that stay damp for extended periods rather than wetting and drying cleanly, which can prolong the shedding phase. Meanwhile the runoff has months longer to find whatever sits below it. The detail that solves it is a drip edge that throws water clear of the wall base, along with a dark or permeable ground surface below rather than pale concrete. Both should be drawn before the steel is ordered.

Weathering steel also needs to drain and dry on both faces to stabilise properly, which rules out laying it flat against a solid substrate. Where it is used as a screen or a panel on standoffs it performs as intended. Where it is fixed tight to a wall with moisture trapped behind it, the corrosion does not stabilise and the material simply keeps going. Reckon on $310 to $640 a square metre fitted. The facade cladding page covers the engineered support arrangements that larger panels need.

Batten Screens and the Overlooking Rule

Vertical batten screens do double duty on Victorian houses and the planning half of the job is the reason so many of them exist. Victoria's residential development standards limit overlooking into a neighbour's habitable room windows and secluded private open space within a defined distance, and a screen with limited openings is one of the accepted ways to satisfy that. Councils across the inner and middle suburbs apply the requirement routinely on second storey additions and elevated decks. The result is that an element installed for a planning reason ends up carrying a large part of the building's appearance.

That dual purpose has a practical consequence worth knowing at design stage. Screening that satisfies an overlooking condition has to go on satisfying it, so the openness and the spacing are not something to adjust on site because the battens looked better further apart. Where a permit condition specifies the screening, changing it during construction creates a compliance problem rather than an aesthetic one. Get the specification from the permit rather than from the drawing where the two differ, and if they differ, raise it before anybody cuts timber.

Structurally a screen is a frame with a skin rather than a skin on its own, and this is where cheap ones fail. Battens need something to fix to at intervals the material can span, which means a steel or timber subframe designed for wind load and for people leaning on it where it borders a deck. Battens held only at top and bottom across a two and a half metre height will move in wind and rattle, and the fixings will work loose. Ask what the battens are fixed to and at what spacing. The answer should involve a member size rather than a general assurance.

Access to the fixings is the item nobody considers and everybody eventually needs. Assemble it so that a single damaged batten cannot come out without dismantling the whole panel and you have a maintenance problem for the life of the building. Screwed from the face with a neat countersunk fixing is less elegant than a concealed clip and vastly more practical, and on a rental or a holiday house it is the right answer. Discuss it before it is built rather than the first time a batten splits. A screen that can be taken apart in sections is worth the slightly less elegant fixing detail. Rentals and holiday houses in particular should be built to be maintained by somebody other than the person who built them.

Screens over windows raise one more issue that comes up on Peninsula and Surf Coast houses in particular. A batten screen in front of glass collects leaves, salt and dust in the cavity between, and where that cavity cannot be reached with a hose or a brush the window behind it stops being cleanable. Sliding or removable screen panels solve it and fixed ones do not. Owners who plan to clean their own windows should raise this at drawing stage.

Expressed Joints, Rainscreens and Where Water Goes

An expressed joint is an open gap in the cladding by design, which means the wall behind it is doing the waterproofing. That arrangement is a rainscreen and it is a sound and well understood approach, provided the layer behind the cladding is a product rated to be the drainage plane and is detailed as such. Water gets in through the joint, runs down the face of the membrane and out at the base through a deliberate opening. Air moves up the cavity and dries what the water leaves. None of that works if the membrane is a builder's wrap installed as an afterthought.

In a heating climate the membrane choice matters twice over. A heated Victorian house drives warm moist air outward through the wall build up for most of the winter, and behind a metal or sheet cladding that air has nowhere to go unless the membrane lets vapour pass. A vapour permeable membrane handles both jobs at once, shedding liquid water inward from the joints while letting vapour out from the framing. An impermeable sarking in the same position traps moisture against the frame. The wall and ceiling insulation page covers the insulation that sits inboard of it.

Cavity ventilation is the part most often compromised for appearance and it is not optional. The cavity needs an opening at the bottom for water to leave and air to enter, and an opening at the top for air to exit, both protected against vermin with a mesh sized to keep insects out without blocking airflow. Designers who close the base of the wall neatly for a cleaner line remove the drainage path entirely. Ask where the water gets out. Installers who have put up a few of these walls point straight at the detail.

Junctions between materials are the other leak source and they need drawing individually. Where charred timber meets expressed joint sheet, where sheet meets a zinc parapet, where any of it meets a window head or a deck ledger, there is a specific flashing that carries water out past the cladding below. Those flashings are often purpose folded rather than off the shelf, which means a lead time and a drawing. A quote that includes a flashing allowance and a schedule has thought about it. One that does not has left the installer to improvise on the day.

Penetrations deserve a paragraph because they multiply on contemporary houses. Hose taps, light fittings, power points, air conditioning pipework, exhaust terminations, gas boxes and conduit all pass through a designed facade, and each one is a hole in the waterproofing that has to be sealed at the membrane rather than at the cladding face. Sealing at the face looks tidy and fails in five years when the sealant shrinks. Getting the services set out before the cladding goes on, so that penetrations land in sensible positions rather than the middle of a panel, is worth a coordination meeting nobody usually holds.

Heritage, Character and Bushfire Limits

Heritage overlays shape more architectural cladding in Victoria than any other planning control, and the way they do it surprises people who expect a blanket prohibition. The prevailing conservation approach favours new work that is clearly distinguishable from the original rather than a convincing imitation of it, which is why so many inner suburban projects pair a restored Victorian frontage with an unapologetically contemporary rear addition. Charred timber and dark expressed joint sheet have become the default vocabulary for exactly that reason. The control usually bites on the street elevation and on anything visible from the street, and leaves the rear largely open. Which is why the same council will approve charred timber behind a house and refuse it out the front.

Which makes the visibility question the one to settle early. A second storey addition that is invisible from the footpath is a different planning proposition from one that sits above the parapet in plain view, and the difference can decide the whole palette. Councils across Fitzroy, Carlton, Richmond, Hawthorn, Ballarat, Bendigo and Castlemaine apply these controls widely and their heritage advisers will discuss a scheme informally before an application. Those conversations cost nothing and they save a redraw. The heritage home painting page covers the colour side of the same question on the original fabric.

Neighbourhood character overlays are the quieter constraint and they work differently. Rather than protecting a specific building, they protect a prevailing pattern, which might be pitched roofs, setbacks, garden frontages or a dominant material across a street. A contemporary metal facade can fall foul of one of those without any individual building being heritage listed. Checking which controls sit over a title costs nothing through the state planning portal and is worth doing before an architect is engaged rather than after.

Bushfire attack level is the constraint that actually removes materials from the palette rather than just complicating approval. Ratings derive from the vegetation nearby, the slope of the land and the distance between the two, they bite on new construction and not backwards, and recladding is new construction for the purpose. At the upper ratings the requirements extend past the material to the way the wall is sealed at its base and to whether any gap above three millimetres is permitted in the envelope. That last requirement is directly at odds with an open jointed rainscreen and with a batten screen.

Designers working through the Dandenongs, the Macedon Ranges, the Yarra Valley and the Otways therefore start with the rating and work back to the palette. Tested and approved systems exist at the higher ratings and they are fewer than the marketing suggests, and the building surveyor is the one who rules on what a given rating allows on a given wall. Establishing that at the outset avoids a scheme that has to be redesigned. Owners in those districts should treat it as the first question rather than a late check. A scheme drawn without it and then assessed against it is a scheme drawn twice. Architects who work those areas regularly start from the rating as a matter of course.

Documentation, Trades and Who Does What

Shop drawings are the single most useful document on a designed facade and they are separate from the architect's drawings. The architect shows intent, the material, the joint pattern and the general arrangement. The workshop set resolves the same wall at a scale where every panel is dimensioned, every batten is located, every flashing is drawn and the module is reconciled against the openings as built rather than as designed. That reconciliation matters because a renovation never comes out exactly as drawn, and a facade set out from the drawing rather than from the actual wall will accumulate error across an elevation.

Expect to pay $1,400 to $6,500 for shop drawings on a house facade depending on complexity, and expect that money to come back several times over. It is the cheapest insurance available on this kind of work, it gives every quote the same basis so the prices become comparable, and it is the document any later disagreement gets resolved against. Some installers include it, some charge for it separately and some will not produce one. That last group should be treated with caution on a designed elevation.

Trade coordination on designed facades trips up more jobs than any material problem. A single elevation can involve a carpenter for the framing, a facade installer for the cladding, a roof plumber for the flashings and parapet, an electrician for the lighting and penetrations, a painter for the coating and occasionally a glazier for the window interfaces. The sequence matters and the interfaces between trades are where things get missed. Ask who is holding the programme together, because on a job with five trades the answer should be a named person rather than an assumption. Where the builder is coordinating, that is straightforward. An owner managing trades directly takes on the sequencing, which is harder than it looks.

Registration and insurance work the same way as on any domestic building job. Past $10,000 the job wants a major domestic building contract and a builder holding Victorian Building Authority registration, and beyond $16,000 the insurance certificate has to be in your hands before any payment. The register lists the class alongside the name, so it also shows whether that registration covers the sort of work being priced. None of that is onerous and all of it is a minute's work to verify.

Material and workmanship carry guarantees under the Australian Consumer Law, which Consumer Affairs Victoria administers here, and registration has no bearing on whether they apply. Problems go to the builder in writing first, then to conciliation, and a hearing at VCAT only if neither settles it. Hardly any facade jobs get that far. Those that do tend to be arguments about a grid or a finish rather than about water, which is one more reason to have the drawings.

Site obligations administered by WorkSafe Victoria apply as they do elsewhere, and two come up on this work. Facade installation on anything above single storey needs proper fall protection and a working platform rather than ladders, since folded metal and long batten lengths cannot be handled safely off a ladder in any case. Owners occasionally suggest doing an upper level themselves and it is not a sensible saving. The material is unwieldy, the tolerances are unforgiving and the fall risk is real.

The second obligation concerns whatever is being removed from the wall. Where a designed facade is going over an existing wall on a house built before 1990, the old material is treated as asbestos bearing until a laboratory rules it out, and how that gets settled sits on the asbestos testing and inspection page. Come back positive and the strip out belongs to a licensed removalist with a clearance step at the end, which is covered on the asbestos removal page. Laboratory turnaround is a few working days and costs nothing to absorb at planning stage. Testing early rather than once scaffold is standing is the difference between a smooth programme and a stalled one.

Maintenance and Repairs on Walls Where Everything Shows

Repairs on designed facades are harder than on conventional cladding for a reason that has nothing to do with the material. On a lapped weatherboard wall a replaced board disappears into the pattern once it is painted, which is why weatherboard replacement is a comparatively forgiving job. On an expressed joint facade the panels are a visible grid, so a replacement panel sits inside a frame of shadow lines that draws the eye straight to it. Getting it to disappear means matching the colour and the sheen of a weathered surface, which is rarely possible, so the honest repair often extends to a whole panel run or to a natural break in the elevation. That is a larger job than the damage suggests and it is the right answer more often than not.

Which is why spares matter more here than anywhere else in the series. A small overrun on each material at order stage, taken from the same production run and kept flat, dry and shaded, decides whether a future repair vanishes or announces itself for the life of the building. Colour and sheen drift between production runs on painted sheet, on factory coated metal and on prefinished timber alike. Nothing bought three years later will match weathered material. A few sheets in a garage rafter is inexpensive insurance.

Maintenance across the palette divides cleanly into three groups. Prefinished metal and painted sheet want a soft wash a couple of times a year, with the effort going into the spots rain never touches. Timber needs its coating renewed on a cycle measured in a few years, and that cycle is not negotiable if the appearance is meant to hold. Zinc, copper and weathering steel need essentially nothing beyond keeping the drainage paths clear, which is the reason they cost what they do.

The drainage paths themselves are the maintenance item everybody forgets. The base of the wall needs its opening clear, and garden beds, paving, mulch and stored firewood all creep upward over the years until they cover it. Cavity vents at the top do the same job at the other end and fill with cobweb and leaf litter. Ten minutes checking both once a year is the whole task. A blocked cavity turns a functioning rainscreen into a sealed box that holds water, which is how a well built facade fails ten years after it was built properly.

Sealant wears out long before the cladding does, and the answer is a fresh bead rather than a repair to the old one. Beads at trims, penetrations and material changes generally want attention somewhere in their second decade, which is an afternoon of work against a much larger bill if one is left to fail. Check them while the wall is being washed. Anything cracked, shrunk away from an edge or gone chalky is due.

Costs in Detail

Expressed joint fibre cement supplied and installed sits at $185 to $360 a square metre in Victoria in 2026, painting included at the upper end and excluded at the lower. Charred or oiled timber battens run $280 to $620 a square metre depending on species, section and whether the material is prefinished or coated on site. Standing seam zinc runs $420 to $780 and weathering steel $310 to $640. Batten screens on their own frame run $240 to $520 a square metre. Prefinished metal plank systems sit below all of these and are priced on their own page.

Support framing and cavity battens add $55 to $130 a square metre and this is the line most often absent from a cheap quote. New work over straight framing sits near the bottom of that range. A century old Melbourne weatherboard house that has moved with the clay beneath it means packing and correcting the substrate to a tolerance a designed facade can accept pushes it to the top and occasionally beyond. Get an answer on how plumb will be established and what straightening costs per square metre, as a rate rather than a reassurance. Somebody answering with a member size and a tolerance has done this before. One who says it will be fine has not looked.

Flashings, trims and purpose folded items run $45 to $140 a metre on designed work, well above conventional cladding trim, because many of them are one off folds rather than stock lengths. An elevation with several windows, a parapet and two material changes carries a surprising quantity of them. A workshop drawing set runs $1,400 to $6,500. Scaffold runs $900 to $4,500 by wall and duration, and a facade needing folded seams or long batten lengths cannot be built off ladders at all.

A whole designed elevation, drawn and detailed and built to that standard, lands between $38,000 and $120,000 in 2026 on a Victorian house. Palette choice drives most of that spread, with zinc and copper at one end and painted expressed joint sheet at the other. Access, substrate correction, the number of material junctions and the quantity of purpose made flashings fill in the rest. Cement sheet coming off a pre-1990 house under licence adds $4,500 to $18,000 ahead of any new material, and framing found rotten behind it becomes structural repairs priced separately.

There is one saving here that gets missed on most jobs and it deserves naming. Projects involving upper level windows, fascia, roof plumbing or high painting alongside the facade mean sharing a single access period between those trades costs a fraction of erecting scaffold three times. That is often the largest available saving on a two storey job and it needs to be planned rather than hoped for. Ask each contractor what their programme looks like and whether it can be aligned. Two weeks of notice is usually enough to shift a start date and save several thousand dollars.

Around Victoria

The bulk of designed facade work in this state sits inside a few kilometres of the city, and what constrains it there is planning and access rather than weather. Narrow lots, rear laneways, heritage controls on the frontage and neighbours a metre from the boundary shape what is possible, and a facade installer working a two metre side setback with no vehicle access is doing a different job from the same wall on an open site. Installers who work Fitzroy, Carlton, Brunswick and Richmond price that realistically. Contractors travelling in occasionally underestimate how much of a day disappears into carting material by hand.

The bayside suburbs, the Mornington Peninsula, the Bellarine and the Surf Coast add salt within a narrow band and a strong appetite for timber and metal. Close to the water, stainless fixings and marine specification coatings earn their cost, and the coating warranty will usually say as much in its own conditions. A kilometre inland the exposure drops away sharply. Holiday houses on those coasts also tend to be unoccupied for long stretches, which argues for a palette that does not need attention every season.

Ballarat, Bendigo, Castlemaine and the goldfields towns combine the widest temperature range in the state with the heaviest heritage controls outside inner Melbourne. That combination means an expansion allowance calculated rather than assumed, and a frontage where the material is very likely dictated while the rear is open. Freight on long timber sections and folded metal from Melbourne is a real line, since the material is bulky and marks in transit. Local mills and local sheet folders sometimes shorten that leg considerably, which is worth a phone call before ordering. A regional supplier who stocks the section you need can also replace a damaged length in days rather than weeks.

Gippsland deserves a mention of its own on this page because the timber comes from there. Mills through Heyfield, Yarram and the Latrobe Valley supply Victorian ash, silvertop and radial sawn boards that appear on facades all over Melbourne, and buying closer to the mill occasionally improves both the price and the lead time. The region also carries bushfire ratings across much of its area, which constrains the palette on local projects in a way it does not constrain a customer in Carlton buying the same boards. Buying local and building local are two different questions in Gippsland.

Through the hill and range districts the bushfire rating governs everything and it belongs at the front of the process rather than the end. Tested and approved systems do exist at the upper ratings, in smaller numbers than the brochures imply, gaps above three millimetres are restricted in the envelope, and that restriction sits directly against open jointed and screened facades. Hand the rating to the building surveyor and have them rule on the wall before a material is chosen. The gable end cladding page covers the small high elevations where the access sum decides the outcome, and the house recladding page covers taking a whole house back to frame.

What to Look Out For

Nothing signals trouble on designed facade work more clearly than a contractor with no workshop drawing and no plan to draw one. The whole appearance of the wall rests on the grid being worked out against the building as it actually stands, in advance of ordering, and a job begun at one corner and carried across ends with a thin offcut at the far end and joints landing an inch off every opening. Request that drawing while you are still collecting prices, and weigh the reply more heavily than the figure attached to it. It is also the only thing a later dispute over a joint position can be measured against.

Watch for silence on the membrane and the cavity. An expressed joint or open batten facade puts the waterproofing behind the cladding, so the membrane product, the drainage opening at the base and the ventilation at the top are the parts that keep the building dry. A quote that names the visible material and says nothing about what sits behind it has priced half a wall. Ask where the water gets out and expect somebody to point at a detail rather than reassure you.

Be careful with quotes that skip the substrate. Framing correction on an old Victorian wall is real work and a designed facade will not tolerate the tolerances an old house arrived with. Anybody who has not looked behind the existing cladding, or who looked and said nothing about plumb, has either absorbed a risk they will later argue about or has not understood the job. Put the framing allowance back into the lowest price and the distance to the others largely disappears.

Watch the junction details where materials change. Every meeting between charred timber and sheet, between sheet and a parapet, between anything and a window head, needs a flashing drawn and priced. Improvised junctions are the single most common source of facade leaks in this state and they are invisible until the first sustained southwesterly. Ask to see the junctions on the drawing rather than on the elevation. Elevations look resolved because they are drawn at a scale that hides the problem. A section cut through the junction is the drawing that shows it, and it takes a minute to read.

Finally, be wary of a weathering steel proposal with no drip detail and pale concrete below it. The runoff during the stabilising period will stain whatever sits underneath and the stain is difficult to remove, and a Melbourne winter extends that period rather than shortening it. The fix is a drip edge and a dark or permeable ground surface, both decided before the steel is ordered. Anyone raising it unprompted has built these walls before. Guarantees on the material itself sit under the Australian Consumer Law administered by the ACCC, and a stained path is not usually a product fault.

How to Get Comparable Quotes

Start with the drawings if you have them and with a clear statement of intent if you do not. Say which elevations are in scope, what the palette is, whether painting is included and whether an architect is involved. Flag whatever you already know about the wall, the bow through the middle, the addition nobody built plumb, the sheet you suspect is fibro, since visible difficulties get priced as work while hidden ones get priced as risk. Saying so at the first visit is the cheapest leverage an owner ever has on this sort of job.

Then put an identical list of questions to everybody. Who draws the workshop set, how the module resolves against openings, the membrane product and who supplies it, the cavity drainage and ventilation detail, the substrate check and correction rate, the flashing schedule including purpose folded items, the fixing specification, the coating system and its warranty, access, lead times, spares and both warranties. Using the same words with each of them is what turns the gap between their figures into information. Those ten minutes with a pen before the first visit pay back several times over.

Ask each of them what they would change about the drawings. The answers are more informative than the prices, because an installer who has built these walls will name a junction that will not work, a batten spacing with nothing to fix to, or a detail that needs a flashing nobody has drawn. Somebody with nothing to say about a complex facade has either not read the drawings or not built one. That single question sorts a field of quotes faster than anything else on the list. It also tells you who will be useful to deal with once the work starts.

Read the methods against each other and leave the bottom lines for last. Where two contractors have committed to the same workshop set, the same membrane, the same cavity arrangement, the same straightening and the same flashings, whatever separates their prices is genuine competition. A price that undercuts the rest by precisely the drawings, the membrane and the straightening has quoted another wall entirely, and the earlier sections describe how that wall performs by its third winter. Take the omissions back to whoever produced it and watch what happens to the number.

Keep the whole file afterwards and store it where it survives a change of ownership. Workshop drawings marked as built, material names and colour references, the membrane product, the coating system with its renewal cycle, the flashing schedule, images of the framing and membrane taken before anything was covered, and the spares. Those images are the only record of what sits behind a facade nobody can open for a look. A file of that standard reads as careful work to anybody doing a building inspection, and a documented wall sells more easily than an undocumented one.
