Is an outdoor kitchen worth building before you sell in Cranbourne? Mostly no, and here is what to do instead
Not a new one. Building a $25,000 to $50,000 outdoor kitchen eight weeks out from a campaign is the worst spend on this page: sellers rarely get back more than about half of it, and the build pushes the listing into the wrong month. What does pay in this market is fixing and presenting what is already there. Budget $2,500 to $8,000 to get retrospective approval on an unpermitted alfresco, $400 to $1,600 to make stormwater discharge properly, $700 to $1,800 to clean, reseal and re-oil, and $200 to $600 for a deep clean before the photographer arrives. Those protect the price. A new build chases it.
Every job, what it costs, what it actually does at sale, and a straight verdict
Costs are 2026 City of Casey rates. The middle column is deliberately worded as “adds” or “protects”, because most pre-sale money on an alfresco protects a price rather than adding to one, and knowing the difference is what stops people overspending.
| Job | What it costs | What it adds or protects at sale | Verdict |
|---|---|---|---|
| Retrospective approval for an unpermitted alfresco | $2,500 to $8,000, 4 to 10 weeks | Removes a section 32 disclosure problem and the buyer’s biggest price-chip lever | DO IT |
| Repair storm-lifted roof sheets and rusted post bases | $900 to $6,500 | Protects. It will be named in the building report either way, so pay the tradesman not the buyer | DO IT |
| Fix stormwater so roof water goes to a legal discharge point | $400 to $1,600 | Protects. Water pooling against a slab is a headline defect and reads as a structural risk | DO IT |
| Rectify non-compliant gas or electrical | $450 to $1,800 plus certificates | Protects. A safety defect in a report is the strongest negotiating line a buyer gets | DO IT |
| Clean, reseal the benchtop, re-oil timber, touch up the ceiling | $700 to $1,800 all up | Adds, in presentation terms. This is the highest return per dollar on the page | DO IT |
| Professional deep clean and styling before the photographer | $200 to $600 | Adds. Every listing photo of the backyard is taken from this space | DO IT |
| Roof an existing sound slab, Colorbond alfresco | $12,000 to $25,000, 12 weeks with permit | Can genuinely add, because it converts an unused slab into year-round living area | ONLY IF the slab is sound and you have 12 weeks |
| Simple BBQ bench and bar wing under an existing roof | $6,000 to $12,000 | Modest. Helps a bare alfresco photograph as a room rather than a carport | ONLY IF the covered area currently looks empty |
| New full outdoor kitchen: stone, sink, kegerator, appliances | $25,000 to $50,000, 8 to 14 weeks | Rarely recovered. Buyers discount someone else’s appliances and layout | SKIP IT |
| Wood-fired pizza oven | $4,000 to $8,000 kit plus masonry | Close to nothing at sale, and some buyers read it as maintenance | SKIP IT |
| Upgrading a serviceable benchtop to porcelain or premium stone | $600 to $900 per sqm | Invisible to most buyers standing in the yard for 90 seconds | SKIP IT |
| Adding strip heaters or extra ceiling fans | $880 to $1,800 each installed | Not valued separately by buyers. Replace broken ones, do not add new ones | SKIP IT |

Pre-sale make-good estimator
A ballpark for the repair-and-present path, not the build path. Set the size of your covered area, be honest about its condition, and tick what applies.
What buyers actually notice in the first 30 seconds
Watch people at an open home in Cranbourne East or Narre Warren South. They walk through the kitchen, slide the back door open, step onto the alfresco and stop. What they register in that half minute is not the brand of the BBQ.
- Is it usable in February and in July. Shade, a roof, and somewhere the northerly does not blast straight through. A covered area reads as extra living space; an exposed slab reads as a slab.
- Does it feel connected to the house. A level threshold, a matching floor finish and a roofline that looks designed rather than bolted on. A tacked-on roof at a strange pitch does real damage to first impressions.
- Is it clean and dry. Green mould on a slab, a rust run down a post, cobwebs across the ceiling battens: buyers read these as neglect and start wondering what else was not looked after.
- Where does the water go. Staining on the wall, a puddle at the base of a post, a downpipe finishing in a garden bed. This one moves from impression to inspection report very quickly.
- Does anything look unsafe or unfinished. An exposed gas hose, a double adaptor under the bench, a fan hanging on a temporary lead. Buyers may not know the standards, but they know improvised when they see it.
None of that list is expensive to fix. All of it is expensive to leave.

What shows up in a building or pest report, and what it costs you
A pre-purchase building inspection in Victoria is normally carried out to the Australian Standard for pre-purchase property inspections, AS 4349.1, and a timber pest inspection under the matching standard. Both are visual inspections of accessible areas, which is exactly why alfresco defects get written up: the whole structure is standing in the open.
The five findings we see most often on an outdoor entertaining area:
- No evidence of a building permit for a roofed structure. The inspector notes it, the conveyancer chases it, and the buyer asks for money or a resolution before settlement.
- Water pooling or discharging against the dwelling. In Casey’s reactive clay this is not cosmetic. Repeated wetting and drying at the edge of a slab is precisely what causes footing movement, and inspectors know it.
- Rot or termite activity at the base of timber posts. Untreated pine set into or against concrete is the classic. A pest inspector will note conducive conditions even where there is no live activity.
- Rusted post bases and fixings. Common on older builds and on the southern edge of the service area toward Cranbourne South, where there is enough salt in the air to matter.
- Visible non-compliant gas or electrical. An LPG bottle feeding a fixed BBQ under a roof, a lead running out a window, a light fitting that is not outdoor rated.
Every one of those becomes a number in a negotiation, and the buyer’s number is always bigger than the tradesman’s. A $1,200 stormwater fix becomes a $5,000 ask. That asymmetry is the whole argument for fixing before you list.
Fix it or disclose it
There are only three honest options with a known defect, and pretending it is not there is not one of them.
Fix it. Right for anything safety related, anything cheap, and anything that will be written up in a report. Gas, electrical, stormwater, structural fixings, rot. Get the certificates and put them in the file.
Fix the approval, not the structure. Right where the build itself is sound but the paperwork never existed. A registered building surveyor can assess an existing structure, and the pathway usually needs engineering computations confirming the frame and footings are adequate. Budget $2,500 to $8,000 and 4 to 10 weeks in the City of Casey, and start it before you list, because a purchaser will not wait.
Disclose and price it in. Right where the fix is genuinely large relative to the value, for example a tired 1990s pergola on a house being marketed to a buyer likely to rebuild the back yard anyway. Tell your agent, let them position it, and do not spend $18,000 on a structure the next owner will demolish.
A quick note on owner-builder work, because it catches people out. If the works were owner-built within the last six and a half years, Victorian sale rules bring extra obligations including a defects inspection report and insurance requirements. If that is your situation, get the conveyancer involved early rather than three days before the contract goes out.
How long you actually need before the campaign
| Work | Lead time | Start no later than |
|---|---|---|
| Deep clean, reseal, re-oil, touch up | 3 to 10 days | 2 weeks before photos |
| Repairs: sheets, fixings, gutter, stormwater | 1 to 3 weeks | 4 weeks before photos |
| Gas or electrical rectification and certificates | 1 to 2 weeks | 3 weeks before photos |
| Retrospective building approval | 4 to 10 weeks | 12 weeks before listing |
| New Colorbond roof over an existing slab | 8 to 12 weeks including permit | 16 weeks before photos |
| Full outdoor kitchen build | 8 to 14 weeks | Do not start it for a sale |
Season matters here too. In this corridor the strongest backyard photographs come off a bright day in October or March, and a half-finished structure in a listing photo is worse than no structure at all. If you are inside six weeks of your first open, the right plan is repairs and presentation only. Our page on the best time of year to build an alfresco in Cranbourne goes into the weather and permit timing in detail.
Two jobs we would honestly tell you not to bother with
We build outdoor kitchens. Both of these are things we could sell you tomorrow, and both of them are the wrong call for a seller.
1. A brand new full outdoor kitchen. Twenty-five to fifty thousand dollars, eight to fourteen weeks, and a finished product built around your taste rather than the buyer’s. In practice the market treats it as a nice feature rather than a valued asset, and you carry the whole risk of the timeline. If you want that kitchen, build it and enjoy it for five years. Do not build it for a campaign.
2. A wood-fired pizza oven. Four to eight thousand for the kit and the masonry, plus flue work, and at sale it is close to invisible. A meaningful number of buyers actively read a solid-fuel appliance as smoke, ash and maintenance. If you have one, sweep the flue for $180 to $350 and clean it up. Otherwise leave it.
A third, for good measure: do not upgrade a serviceable benchtop. Nobody standing in a backyard for ninety seconds can tell a well-sealed poured concrete top from a porcelain slab, and the $600 to $900 per square metre difference stays in your pocket where it belongs.
We also will not pretend to be your valuer. We do not do property appraisals or estimate what any change does to a sale price in dollars. What we can do is tell you what the structure needs, what it costs, and how long it takes, so you and your agent can make the call with real numbers.
Where to read next
If you are weighing the spend, start with what an alfresco does to resale value in Cranbourne and the current 2026 price guide. If the structure has no paperwork, the City of Casey permit page explains the approval path. If the report has already come back with defects, the warning signs page tells you which ones are serious. Landlords selling a tenanted property should also read the rental obligations page, because access and notice rules apply to your trades as well as your agent. And if you are keeping the place, the maintenance schedule is the cheapest way to never need this page.
