The only thing I would bear in mind if you're going to do it this way is: are you a household who leaves your washing up to drain, or do you dry it immediately and put it away? (I know you'll have a dishwasher but there is always some non-dishwasher washing up). Because if you have stuff sitting and draining bear in mind that it will be sitting and draining in almost the middle of your kitchen, probably in the first place your eye will rest when you enter the room, rather than off to one side.
Obviously if you are a household where you dry up and put away immediately then this won't be an issue. But even then you will need to give consideration to what kind of draining board - if any - you put in. A stainless steel draining board will be very obvious, but a "grooves in the worktop" style will be much less obtrusive (but more expensive). A drying rack on a tray or a towel that can all be put away when not in use (so no drainign board at all) would be the cheapest option, but it will pay in the long run to realistically assess what our washing up habits actually rather than what you would like them to be once you have a nice new kitchen to practice them in.
