The owner of the van does computer work for an income. The cabinet was designed to reclaim space that would otherwise be unused. At the bottom it is only as deep as the wheelwell. In the middle it gets deeper because the van body curves outward where the window is. The inside part of that shelf is about 10" deep extending to the outside window. At the top it is very shallow with just enough space to store her laptop and keyboard. With the doors down it becomes her workstation for cooking or computing, (monitor sits at eye level on top shelf, keyboard on the middle shelf at hand level. They like to stand up when they work. They can also sit on the bed that faces the cabinet and the monitor is still at eye level). There is enough space in the middle of the van for them to walk past the cabinet with the doors down. To help you visualize the middle shelf, in the second picture you will see a red thing in the cabinet. That is their tea kettle they put there for storage. It may be hard to see the shelf as I used 5 ply prefinished birch plywood that is giving a reflection from the window light.
In the first picture if you look at the end of the lower dowel rod you will see wooden latches, (shaped like surf boards), when these are turned horizontal the lower storage area opens up, (door opens at the top and folds down to the floor). They also had a solar panel installed and there is a power supply inside of the cabinet to charge up her computer or run a desk lamp etc. Both 12 and 120 Volt are there.
The cabinet does not have a lot of internal space, but it was space that was previously unusable. It is a very personalized item. The height of the shelves are to fit their needs and comfort. They got to choose the grain structure of the plywood I used in most parts, ( this used more plywood, but the scraps were used in other projects so no real loss). The owner spent a lot of time overseas working so I tried to give the cabinet an Asian flair with the rope and dowels. Most of the screws in the structure are hidden, (only the top screws that hold the cabinet to the top rail of the van are exposed). There is a piece of wood that was part of some furniture she has hung on to and has sentimental value. The ropes and dowel that support the top shelf would normally hang in front of this wood blocking some of it's view so I added two other side knobs to take up some slack in the ropes and raise the dowel higher when the upper door is closed. It actually took more like a week and a half to design and build. Like I told them, it takes 10 seconds to drill a hole and 10 seconds to put in a screw. It takes an hour to figure out where you want to do both.
