Zen Carpentry is NYC's #1 maker of loft beds. We have an entire web page dedicated to just this. Here are some interesting loft beds, some with cubby staircases, some with ships ladders, some with custom-milled, small batch local hardwoods.
Here's a special loft bed we designed with our draftsman, Rene Reyes, for a loft space in Long Island City, NY. Included small LED over-head lights.
