I prefer to have all the appliances integrated, it gives the kitchen a far more streamlined appearance imo. Of course not everyone wants that look it's very much an individual choice, we were talked into it by the kitchen people when we had ours done about 4 years ago, but in retrospect I don't regret it. Sometimes when I'm on Right Move and see a fairly new kitchen where appliances such as an American style fridge are stand alone that would not be my choice, I know loads of people love them but they look like a big solid silver mass, I just don't like that. I don't have my washing machine, tumble dryer or freezer in my kitchen they are all in the garage, so the only integrated appliances, apart from built in cooker and microwave, and yes it's great not have the latter taking up work surface space, are a fairly large fridge and dishwasher. They are more expensive to replace than conventional appliances as they have to be tailored to fit the cupboard doors, touch wood they have plenty of life left it them.
