Here are more drawings of the Nine Tiny Feet design. The interior is 78″ high (6 1/2′), the sleeping loft is 34″ by 76″ and extends over the porch. The bay windows server double duty as windows and space for small cabinets to hide away plumbing and the 12V DC cooler.
I still need to think through how the trap door to the loft will work and the vent for the fireplace (not pictured here) which will sit in front of one of the bay windows. I think there is enough room for the stack to vent out the bay window roof. If that doesn’t work I may put if over the toilet/chair.
I’ve made a few scale models from cardboard as the design has evolved. I’ll make a new one with these revised dimensions and post photos of it next. 3D drawings help visualize the space too but I find old school hot glue and cardboard does a much better job.
