Author Builds Tiny Solar-Powered Off Grid Cabin for Under $2,000!
~
Homesteader and author LaMar Alexander lives in a tiny, self-sufficient 400 square foot cabin that he built himself for under $2,000! Powered by a 580-watt solar system and a 400-watt wind power system, this cute little cabin runs entirely off the grid. Hoping to inspire others to follow in his footsteps, Alexander has even written a step-by-step guide that will teach you how to build your very own tiny sustainable home!
Alexander’s two-floor cabin measures 14×14 with space for a full loft, kitchen, bathroom, dining, living and office space. The space-efficient home can even sleep up to six people comfortably. In addition to an off-grid power system, the cabin includes a rainwater and gray water harvesting system, with his main water supply sourced from a hand-drilled water well. His bathroom consists of a solar composting toilet and propane-powered shower; propane is also used for the heater.
