@TeeDee, do you mean just the useful things that would be used outdoors to keep the mess in the kitchen to a minimum ?
Anything that squirts, drips, stains, smells ? that kind of thing ?
Tbh, a decent stainless steel sink, and a stable worktop beside it, under cover, would do fine for most things.
Wood left outside in the damp here grows green. Every fence, gate, shed, roadsign and bus shelter here is green with algae. If you don't have that, then you'd get away with leaving wooden utensils outside. Other wise, I wouldn't. Baskets go mouldy
Stainless steel, plastic and enamel. I find plastic jugs left outside, (I use them for dyeing) crack because they aren't UV stablised, so not all plastic is good outdoors.
If you're having a sink, mine just drains into a bucket beneath, try to get it fitted to drain properly. Mine's out beside the greenhouse and I just lug the bucket out and use it in the garden, but it's a chore, and you've to mind and not let it overflow. If you're doing it from scratch, I'd try to sort out the water in and out. Garden tap sets can be bought for under twenty quid, and they come with all the fittings necessary....once you manage to drill a hole through the wall
Other than that, hit the poundstores for utensils. Big stainless steel spoons and ladles, tongs, colanders and sieves are a pound. Cutting boards sets too.
Big stock pots are very thin bottomed. They're meant to simmer long and low and with lots of liquid, so nothing sticks. Anything else you do in them will stick. I found that car boot sales are excellent places to find old maslin pans, or army billies, or again, Ikea and their 'student' range of pots and pans does fine for smaller quantities. Pretty sure I got two for a fiver. Those aren't the big ones, but they're good for boiling up stuff such as willow bast, moss, acorns, elderberries and the like.
Just now the supermarkets are selling off their outdoor dining stuff. I bought three big serving bowls, for a pound each last week. Bowls that you don't mind getting stained are good things
See if you can find a big mortar and pestle. I've got a big granite one and it's excellent for everything from cracking nuts to grinding down charcoal for making glue. You can do it with just a bit of paving slab and a comfortable in the hand stone, but the mortar and pestle makes it easy, and it's easy to sweep up nut shell bits whereas they rattle like something demented in the hoover indoors.
Some way to hang up stuff to drip through a cloot, or a jelly bag, where spatters won't matter, would be awfully useful at times too. Blackcurrants, plums, brambles, rosehips, anything with tannin....they all make a mess that stains.
