I will update this description with a link to where you can download my full plans once this is completed (designing it as I go) - The end result is a castle loft bed that can hold a Twin mattress above or below (could be used as a bunk bed) This is not a kit or pre-built plan nor anything I am building off blueprints. I'm working out the measurements and details as I go and will explain each step of the design and build process. Cost was around $500 or so, relatively low skill level required and could easily be simplified further
