It's cupboard sized - 2m x 2m roughly
Love the idea of the deep sink - that would be really helpful as I'm always splashing mud all over the place!! Also the pull down shelves - great idea. There will be a stepladder in the utility because the ceilings of my house are highish (2.6m) and I need storage for things I don't use that often but want to keep.
I think I am going to put my hoover and mop in the high understairs cupboard, which is a separate area. I am fed up with lugging around a canister vac that weighs the same as a small elephant, so when it goes I will get a Dyson cordless. Putting a plug point in there so I'm ready for it!
The big cupboard is actually a freezer - sorry I should have mentioned that. I have a lot of frozen stuff, and I don't have space for a full-height one in the kitchen. I think there will be space for an ironing board next to it, though I may not be able to put a door on it.
No dryer - I currently just use racks, will probably buy a washer-dryer in future and put some of those Ikea Grundtal things on the wall too. This is a bit of a sticking point between DH and me: he thinks we need work surface in the utility for things like bread-making and liqueur-production (we do a lot of this kind of thing) plus a microwave (he does not want the last of those in the kitchen). I would prefer to have a separate washer and dryer. I think he's probably the more practical in terms of his ideas and our lifestyle here.
I know it sounds stupid, but there's something I just don't like about the design. DH, however, makes the point that by storing a load of stuff in there, we can have a more aesthetically pleasing kitchen. I think I probably just need to accept that as a tradeoff.
