Mine is 3m x 3m. It is the same size as the kitchen. It has top and bottom kitchen units along one of the walls and bottom units on another wall. the 3rd wall has the washing machine and dryer and the boiler above these. We have a work top that runs the whole length of 3 walls.
We have a huge coat/shoe rack in here too which is rammed with coats so we shall have to rethink the coat storage. We also keep our bins in here.
The spray mop and vacuum cleaner are leaning against the coat stand.
The kitchen cupboards in here are rammed with kitchen stuff as we don't have enough storage in the kitchen itself. I also think we have too much stuff that we need to get rid of. The cupbaords house the tupperware (too much), serving dishes, a whole cupboard dedicated to baking things; too much since I haven't baked in over 2yrs, my work PPE (much needed so this is very good use of that cupboard), under counter freezer, corner cupboard has kitchen rolls, bulk bags of spices/herbs, huge bag of rice; DMum (bless her) insists on bringing 10kg bags with her each time she visits, food mixers, bbq gadgets (need to get rid) and another cupboard for washing powder, bin bags, car screenwashes, etc. The other top cupboards have junk food, canned foods, jars, more spices and herbs and the other has wine glasses and flutes, jugs.
The top of the surface, we have basket with onions, potatoes, garlic, cookbooks perched in one corner.
Plenty of storage but I think it is poorly used. No sink in there which I would like to have. We plan to do the kitchen so we shall get the utility reconfigured.
