I love the counter on top of the washer and dryer and extends all the way to the door and incorporates the sink. Under cupboard lighting is a good idea and I need a new laundry door and this could be an option, it will let more light in.
Full height cabinetry allows for easy concealment of brooms/mops/vacuum cleaner. Having the washer and dryer separated creates more benchspace in an already tight area. Perhaps framing the dryer with cabinetry would create a more streamlined look.
