Does an alfresco actually add value before you sell?
Short answer: it helps, but not the way most people think. In Cranbourne an alfresco rarely returns a neat dollar-for-dollar uplift. What it does is make the house sell faster, photograph better, and stop buyers mentally deducting the cost of finishing the job themselves. Here is what we tell owners who ring us eight weeks before an auction.
What a Cranbourne alfresco really does to a sale.
We get this call most weeks between August and October, right before the spring selling season. The question is always some version of “if I spend $30K on the alfresco, do I get $30K back?” The honest answer is that nobody can promise you that, and anyone who does is selling you something. Valuers do not have a line item called “alfresco”. Buyers do not run a spreadsheet at an open-for-inspection.
What actually happens in the Cranbourne market is subtler. A large share of the stock listed here through Cranbourne East, Selandra Rise, Eden Park and Botanic Ridge was handed over between 2018 and 2024 by a volume builder who finished the alfresco at a concrete pad, four posts, a ceiling lining and one capped gas point. Every second listing in those streets has the same unfinished square of concrete out the back. When a buyer walks through six of them on a Saturday and one has a finished roof, a working BBQ, a benchtop and a light on, that house stops being interchangeable. It gets remembered, it gets a second inspection, and it gets a bid.
The reverse is the part people underestimate. An unfinished pad does not read as neutral to a buyer. It reads as a job they now have to do, and they mentally deduct a number that is almost always bigger and rounder than what it would actually cost. We have had agents tell us buyers wrote off a back yard at “$50K to fix” when the real cost of roofing that pad was closer to $18K. That gap between the perceived cost and the real cost is where the pre-sale build earns its keep.
Three build levels and what each one does at an open.
Level one - roof the pad and stop there.
A Colorbond roof over the existing slab, engineered to AS/NZS 1170.2 for the Region A5 wind loading Cranbourne sits in, plus a couple of downlights and a fan on an AS/NZS 3000 compliant outdoor circuit. Around $14,500 to $22,500 for 25 square metres, plus $880 to $2,400 for the electrical rough-in. This is the highest-leverage pre-sale spend we do. It converts “unfinished slab” into “covered outdoor room” in the listing photos, and the photos are what sells the inspection.
Level two - roof plus a modest BBQ wing.
Add a built-in BBQ, a gas line run from the house manifold with an AS 5601 compliance certificate, a 2.4 metre benchtop and some cabinetry. Call it another $8,000 to $14,000 on top of the roof. This is where a space starts to feel like a room rather than a shelter, and it is usually the sensible ceiling for a house you are about to list. See our BBQ installations page for what a proper gas install involves.
Level three - the full entertainer build.
Premium outdoor kitchen at $12,500 to $28,500, wood-fired pizza oven, a bar fit-out, louvered roof at $22,500 to $35,000. A genuinely brilliant space, and the wrong call if you are selling in six months. The buyer who wants exactly your oven and exactly your bar is a small slice of the market, and the buyer who does not want them will not pay for them. Build this one for yourself, not for a valuer.
A real-shaped example - Cranbourne East, 2026.
Four bedroom, double garage, 2019 handover, 480 square metre block, existing 5.5m by 4.5m alfresco pad with posts and ceiling lining already in place and one capped gas spur. Owner listing in March. The quote we would write:
- Colorbond roof over the existing 25 square metre pad, engineered to AS/NZS 1170.2 Region A5: $17,800
- City of Casey building permit plus engineering certificate: $1,150
- Electrical rough-in, four downlights, one ceiling fan, two weatherproof outlets, AS/NZS 3000 certificate: $2,050
- Beefeater Discovery 1100E built-in BBQ, gas line from the manifold, isolation cock, pressure test, AS 5601 certificate: $5,400
- 2.4 metre polished concrete benchtop with two cabinets either side: $4,600
Total: $31,000 including GST, roughly six weeks on site once the permit issues. Would a valuer write $31,000 back onto the appraisal? Probably not. Would that house present better than the four identical listings within a kilometre of it and sell in the first campaign instead of the second? That is the actual bet, and it is a far more sensible one than chasing a valuation number. Our pricing guide has the full 2026 rate card if you want to build your own version of this sum.
The other half of a pre-sale build is the calendar, and it is the part that catches people out. Six weeks is not enough runway once the City of Casey permit is in the queue. Our build timing guide works the dates backwards properly, so your photographer arrives to a finished structure rather than a site.
What does not pay you back before a sale.
- Anything unpermitted. It surfaces at the Section 32 vendor statement and turns into a price negotiation you will lose. See our City of Casey permit guide.
- Highly personal finishes. Copper bar tops, a specific tile you love, a kegerator. Beautiful, and invisible to a valuer.
- A deck instead of a roof. More money, less usable months, worse photos.
- Cutting the footings to save money. Cranbourne is mostly Class M reactive clay under AS 2870. A thickened-edge slab under a roofed structure moves, cracks the benchtop, and gets found at building inspection.
- Rushing the build so it finishes the week of the photos. A half-finished job in the listing photos is worse than no job at all.
Pre-sale alfresco questions.
Does an alfresco add value to a Cranbourne house before sale?
An alfresco usually helps a Cranbourne sale more through speed and buyer competition than through a clean dollar-for-dollar return. In our experience a finished, permitted, roofed alfresco with a working kitchen makes a Cranbourne East or Selandra Rise home present far better at open-for-inspection than the bare concrete pad next door. We will not promise you a valuation uplift figure, because nobody honestly can. What we can say is that an unfinished alfresco pad reads as an unfinished house, and buyers price that in.
How much should I spend on an alfresco if I am selling within a year?
Keep it to the cheaper end of the range. A Colorbond roof over the existing pad at $14,500 to $22,500 for 25 square metres, plus a modest built-in BBQ install at $3,000 to $8,000, presents almost as well in listing photos as a $50,000 build and leaves you far less to recover. Save the $28,500 premium kitchen, the wood-fired pizza oven and the kegerator bar for a home you intend to stay in.
Will an unpermitted alfresco hurt my sale?
Yes, and it is the single biggest problem we see. A Class 10a structure built without a City of Casey building permit surfaces at the Section 32 vendor statement stage, and the buyer's conveyancer will ask for the certificate of final inspection. No paperwork means one of three outcomes: a price reduction, a retrospective permit application, or a demolition condition on the contract. Retrospective approvals cost more and take longer than doing it properly the first time.
Is a deck or an alfresco roof the better pre-sale spend?
A roof, almost every time, in Cranbourne. Our summers run to the high 30s with hot northerly winds and our winters are cold and wet, so an uncovered deck is genuinely usable only a few months a year and buyers know it. A roofed alfresco is usable year round and photographs as an extra room rather than a patch of yard. If the budget stretches to only one, roof the pad first and lay the deck later.
How long before listing should I start the build?
Allow four to eight weeks for the City of Casey building permit, then ten to twenty days for a roofed alfresco build, plus another five to ten days if an outdoor kitchen is included. Work backwards from your intended listing date and give yourself a three month runway. Starting six weeks out means your photographer arrives while we are still on site and your listing goes up with a half-built structure in the frame.
