When we were in high school our dad made us a simple desk out of an old door and a pair of metal saw horses. At the time we didn't have a computer to take advantage of the organic cable wrangler, but by college we quickly learned how useful that doorknob hole could be. Turning old doors into desks has now become an age old solution, but where you get your door from can differ from project to project. You don't need to wait until a large room divider comes your way, rather you can do as the folks over at Young House Love recently did, and use a narrow bathroom closet door to create a two person work station.
While regular doors allow for a ton of workspace, sometimes a room just doesn't allow for that much tabletop. Bathroom linen closets tend to have narrower doors, which can work just as well as a desk, and allow you to skip out on a lot of cutting.
Sherry and John of Young House Love recently unlatched just such a door and stored it in their garage. When they were planning out their home office they pulled it back out. A quick cut shortened it to the right size, and a trip to Home Depot got them the wood they needed to add on some legs and a rail.
The workspace is split naturally with a small shelf/cabinet placed smack dab in the middle.
