1. As said earlier: two dishwashers.
2. Have a walk-in closet next to toilet or other place when you change in to pajamas after a day. Make a few holes on the head level in the wall separating the closet from the toilet. One hole for one kind of clothing (i.e. 3: colors, whites, baby clothes). In closet under each hole place a basket with a hole near the bottom. Each basket is a laundry queue. Buy washer/drier combo (or two). Place it in your closet under baskets. Place a washing powder dispenser just above the machine's washing powder bay.
