I keep my pans on top of the wall units.
Some cleaning stuff is under the sink, I could move it into the bathroom, but that's fairly tiny as well 
I'll see if I can find a trolley that will fit under the leggy work surface, good idea. I have one in a corner next to the base unit, as nothing what would fit there.
There's just myself and dd15, but also a dog (small) and three cats! I already feed the cats on my bedroom windowsill to avoid the dog eating their food!
There's also a living room to sit in,a dining room, but that's full of the clothes airer, book shelf, cat scratching post and dining table that is currently serving as a desk too.
No utility place, just an understairs cupboard that houses the litter trays.
On the work surface there's the microwave, toaster, kettle, sugar bowl, butter fish. The window sills are full of liquid soap bottle, washing up liquid, utensils jar for wooden spoons, knives etc, cookie jar, radio, jar full of pens, kitchen towel holder, scales, dug dog food container ..
Good idea re wine glasses - I rarely drink wine anyway, so I'll box them up and out put them away.
I can't use the cupboard under the stairs, I don't have anywhere else to keep the litter trays and cat litter.
Definitely looking at minimum spend - I've no money and don't know how long I'll stay here.
I've no room for a dresser elsewhere unfortunately.
I've attached a photo of the kitchen (before I moved in).
Thanks for all the suggestions. Not sure about a window shelf, I'll have a think.
