Are you building the room?
No it is my kitchen. Would like to conceal the washer, dryer and water heater.
Do you want to enclose the appliances? Please post a picture of the space as it looks now so that we can see what you have to work with.
You can buy very inexpensive plastic drawstring doors and blinds at any home improvement store. Or use plywood, paneling, corkwood doors, or pegboards for walls and dividers. You could even use chicken wire and decorate it with rope or yarn or pictures hung with hooks. Best wishes, Lanie. Jewell

Lots of neat ideas. My washer opens from the top.
