Its a very British thing to not have a full floor in Kitchens, not sure why
Maybe we were more likely to have to (or want to) pull the floor up and dick with it than pull the kitchen out and dick with it. Either way, it's not great in my view.
get the washing machine out of where you make food
This is another thing they do right in Euroland. As long as you aren't afraid of having a plug sockets in the bathroom it makes all the sense in the world to put the washing machine in there.
