Laundry
If you are building the room from scratch, install batt insulation in the walls to reduce noise. These are heavy appliances that move around a lot. If the laundry is going to be on an upper floor, the floor joists should be reinforced to handle the load. Stiffening the floor will also reduce noise from rattling objects nearby. Make sure you are using braided stainless steel hoses to prevent leaks.
