Well we moved into an apartment and as you know, they aren't known for the amount of space they have. We needed a place to sleep and a place to work. This gave us an idea, sleep above the workspace with loft beds!
You can build one in an afternoon if you stick with it and it can be made for under $100. We didn't stain ours because we like the look of the bare wood (haha) and it wasn't worth the effort.
After we had the idea, we started looking around for plans. None of them really fit our situation exactly, but we used some ideas from each of them. You can manipulate, add or subtract from these plans. They are just what suited us.
There is a Google sketchup file I uploaded that is the project.
