Using wood left over from the REX shenanigans in the East Campus courtyard, my roommate and I built a double loft in our room. We put up the loft in record time - we only had to sleep in our institute-provided beds for a total of one night before we could sleep in the loft. The design we used was based on another loft down the hall. It spans the entire room, so there are no supports in the middle of the floor, and it is tall enough to walk under without having to duck. It also includes integrated speaker mounts, a cruft shelf, and LED strip lighting.
