The next is one for larger families more than couples. We have a W/D closet but did not want the appliances. While on the road we purchased a Rubbermaid shelving unit that was close to what we wanted. It was placed in the closet and used as a pantry. However, it had space on all sides so items fell behind the shelf and it also seemed to consumer a lot of space.
So, while in Georgia, I took out the shelves and built my own.
I put two 2x4s on the back wall to space and protect the plumbing. Then I add a back wall of plywood and two side walls. To these I simply attached adjustable shelving bars. Then, I cut shelves and dropped them into place.
This is a view under a shelf. You can see the bars and the pegs that hold the shelves. This allows me to adjust each to the idea height. Also, because the fill the space, there is no way to drop off the shelf. I was amazed at the space this created. We have enough pantry space for a small european army (or 3 kids) plus the vacuums.
As a cosmetic finish, I painted the shelves and then added a stained trim to match the coach wood.
