The Quixote cottage was inspired by the cottages being used to house the homeless in Quixote village:

After seeing the cottages I researched the design but could find nothing on dimensions or pics of the interior so I decided to take it upon myself to create the design and make it suitable for off-grid living. This includes a solar system, composting toilet, on-demand water heater and fresh water storage tank.
The cabin is 10×20 with a 4 foot covered porch and approximately 135swft of interior living space. It includes a Murphy full size bed that converts to a 5 person dining table, large desk, kitchen, and bathroom with shower.
I estimated the cost for the insulated and roofed cabin with no power or furnishings to be under $5000.
