The base cabinet that is open, without doors, is that the cabinet you are referring to that will have doors and interior pullouts? I think I would go for drawer fronts instead of doors with interior pullouts. Because there are 2 steps involved with a door and a pullout, while only 1 step with a drawer. It could be like a trash drawer. Is there enough clearance between the dirty laundry doors or drawers and the washer front?

How can you access the water shutoff and the dryer vent? You need to access those easily. It would be great if you could have a laundry sink in the room.

I like the clean clothes cabinet, I don't have that. I like the hanging area, I don't have that either, :) Looks like you'll have nice storage overhead.

With your layout, the washer door should be hinged on left and dryer door hinged on right side so you can Stand between the two opened doors.
