I've had seven addresses in the UK and I've never had an American fridge freezer, nor room for one.
I've had just the tall fridges, which are smaller than US fridges, but very adequate and then under counter fridges with miniscule freezers, which I hated.
Hubby designed our house (he works in architecture) and we both designed the kitchen and we still don't have room for an American sized fridge/freezer. We do have a tall fridge/freezer, which is a "built in" one. This amused my Mum to no end! She laughs at the size of it and the fact that she didn't even think we had a fridge/freezer.
We do have a medium sized larder freezer in the garage which the inlaws gave us which is useful for our allotment glut. (They have 2 huge freezers and an American fridge/freezer, for 2 people! And yet when we see them out randomly, it's in a grocery store

I have also just acquired an undercounter fridge going free from a friend in the garage, which is being converted at the moment into a fermentation chamber for home brewing.
