This just gives me the idea of how nice it would be to have some sort of way to store each family member's laundry. Nothing else about it is too appealing. But this is a pretty compact way to do something like that.
Most dryers can't be pushed up against the wall due to the dryer vent so why not build a shelf to cover the gap. Not only does it add more storage but it also keeps items from falling behind the washer and dryer
