Outdoor kitchens and decks that work through a Melbourne year
A barbecue on boards is not a kitchen. Gas, grease, weight and winter all have to be drawn before the spotted gum is ordered.

Melbourne has a short, intense outdoor-dining season and a long period when the same kitchen is a wet sculpture. The Instagram island — stone, sink, pizza oven — wants a climate it does not have. You can still build a serious outdoor kitchen. You have to decide which parts are furniture and which parts are building.
The deck is the floor of that room. It is not a tabletop that happens to run under a grill.
Weight, heat and the hole in the plan
Tell the carpenter the appliance list. A four-burner on a cabinet is one load. A brick oven is another. Point loads need beams, extra joists, or a break in the deck where a concrete pad takes the oven and the timber takes the people. Retrofitting that after the substructure is finished is miserable.
Heat shields and clearances are not optional. A grill against a merbau screen is a scorch mark waiting for a wind change. Non-combustible splash zones, a stone or metal inset, and space behind a built-in for service will keep the timber and the warranty.
Grease will find every groove. A stainless tray and a cleaning habit beat a pale hardwood you wanted to keep virgin. Many people choose a darker board or a tiled inset in the working zone and keep the pretty timber for the table. That is design, not defeat.
Services: gas, water, power
Gas should be installed by the person the law recognises, with isolation you can reach, and not with a hose that trips a child. Water wants a backflow conversation if you are attaching to the house. Power wants weather-rated fittings and a plan that is not an extension lead under a bench.
If the deck is a roof, every penetration is a waterproofing event. Cluster services in a planned riser.
A sink that dumps into a plant pot is a grease story. Drain it properly or skip the sink and wash inside. Melbourne winters will not forgive a romantic copper drain onto clay beside a footing.
Weather, roofs and the month you will actually cook
A kitchen with no roof is a summer kitchen. That can be enough. If you want Easter lunches, add a covered structure that does not smoke you out. Smoke needs a way away from the stacker doors; a north-westerly will otherwise season the curtains.
In July the kitchen should be able to sit wet without becoming a rust farm. Specify 316, drain holes in cabinets, and doors that are not MDF. Insects will occupy any cabinet you do not seal.
Lighting the work surface matters more than festooning the party; see lighting.
Neighbours and the smell of success
A built-in kitchen against a boundary is a courtesy and overlooking problem. Smoke into a child’s window is how a barbecue becomes a file. Put the hot side toward your own garden, not theirs.
If you cook once a week, a good trolley and a table on a simple deck is a better spend than an island you will cover with a tarp. If you cook for a crowd, draw the kitchen as architecture and the deck as the floor that survives it. The sausage should not be the engineer.
Hygiene, pests and the closed months
A cabinet that holds flour and a bag of charcoal through a Victorian winter will also hold mice. Specify metal, close doors, and do not store dog food under the bench. Grease in a groove is a cockroach invitation. A weekly scrape in the season, and a deep clean when you pack the kitchen up, is the maintenance.
Water left in a tap will freeze on the cold nights we still get. Isolate and drain if the kitchen is a true outdoor room.
Design the plate, not only the island
People stand with a plate where the smoke is least. That is often not where the designer put the servery. Watch a barbecue before you bolt the stone. Leave a landing zone that is not in the door swing and not in the stair.
If the kitchen is for two people, a trolley and a table remains a complete architecture. If it is for twenty, the deck has to be a room: light, fall, a rail, and a floor that can take a dropped glass. Draw the party, then the stone.
Cleaning the floor like a commercial kitchen, once
At the end of the season, degrease the work zone with a product that will not wreck the surrounding timber. Rinse into a drain, not into a garden you like. Lift the grates. Look at the frame under the grill for grease that has become a fire story.
Then put the cover on the appliances and let the deck go back to being a deck. A kitchen that can disappear is a kitchen you will forgive in July.
Power, light and the evening service
A kitchen without a dedicated light on the workboard will borrow the festoon and burn a sausage in shadow. Put a shielded strip under a shelf. Put a point for a blender if you are that household. Do not run a daisy chain of cubes under a wet bench.
If the kitchen is on a waterproof deck, the electrician and the waterproofer need the same afternoon, not adjacent months.
The outdoor kitchen that works in Melbourne is the one you can clean, drain and turn off. Everything else is a photograph.
Gas bottles stored in a sealed undercroft are a different kind of hazard to grease. Give bottles air and a lawful position. Give the hose a path that is not a trip. The kitchen is allowed to be handsome after it is allowed to be dull and safe. If you cook twice a year, keep the trolley. If you cook twice a week, build the room. Most Melbourne households sit between those numbers and waste money on stone they cover with a tarp.
Questions we are asked
- Can I sit a heavy barbecue on ordinary deck joists?
- A trolley barbecue, yes if you are kind. A masonry island with a stone top wants extra framing or a pad that does not rely on 450 mm pine joists. Say the weight before the frame is cut.
- Do I need a permit for an outdoor kitchen?
- Plumbing, gas and a roofed structure can trigger approvals even if the deck itself was exempt. Ask. A built-in gas line is not a weekend surprise.
