Bed Building Time!

We recently purchased a small park home (about 223 sq. ft.) and are in the process of fixing it up. It came only insulated, wired, partially plumbed (there's a toilet installed), and with a screened in porch, which adds another 81 sq. ft., but it needs flooring, the rest of the plumbing, and some finishing touches.
Because of the tiny square footage, we decided to build a loft bed so that space under the bed can be utilized better. Read on for how we did it.
