Although we've always had the washer and dryer next to each other, it's still really popular here for people to have a washer in the kitchen and their tumble dryer either in the entrance hall, cupboard under the stairs, or the garage (the latter being the most popular). It can be a bit of a hassle I suppose, but most people do this as it's the only way they can work a washer and seperate dryer around a small space rather than having to have a washer dryer.
I know somebody who has a washer in the kitchen and their dryer under the stairs, and it's quite a nice setup as they have quite a well organised storage for the iron, ironing board, and folded dry laundry worked around the tumble dryer under the stairs, which otherwise wouldn't really be utilised that well if the dryer was in the kitchen.
