How to build a self-sufficient cabin for under $4,000
Not a log mansion, more a well-equipped shed, but paid for in cash and independent of the grid. What went into one well-known cheap solar cabin.
- Filed
Plenty of people want a retreat where they could live off the grid, and most assume it is out of reach. A small cabin built from scratch can cost far less than people expect, as long as the expectations are small too.
One well-known example is the solar cabin built by homesteader Lamar Alexander and documented on his Simple Solar Homesteading website. He reported building a fully self-sufficient solar cabin for under $4,000, and around 2010 he sold his plans as an e-book for $5. The price figures below are his, from that period, and materials cost more today.
What the plans covered
The e-book’s contents list promised instructions for:
- A basic cabin for under $2,000, and an addition for under $1,500
- A solar panel and generator setup for under $1,000
- A solar composting toilet for under $50
- A solarium porch and a solar air heater
- A solar methane digester
- Rainwater and gray-water collection
- A batch solar water heater for under $50
- A solar oven for under $50
- A solar clothes washer, clothes dryer and dishwasher
- A tipi-style greenhouse
- A root cellar that doubles as a storm shelter
- A garden cart and a compost tumbler, each for under $50
- A portable chicken tractor for under $50
- Installing a wood stove
- Digging a water well
- Finding cheap homestead land
What you actually get
This is not a 3,000-square-foot log home. What comes out of these plans looks more like a glorified utility shed fitted out with solar gear. For someone who wants a simple place quickly, or who already has land, that can be enough. Many of the individual projects, such as the solar oven, rain barrels and batch water heater, work just as well at an ordinary house in town.
The financial point stands on its own. A small cabin paid for in cash, with its own power and water, leaves the owner far less exposed in a long outage or a lost job than a large house carrying a mortgage and dependent on every utility.
Check before you build
- Zoning and permits. Many counties set minimum sizes for dwellings, regulate composting toilets and gray-water systems, and require permits for wells and septic. Call the county building and health departments before buying land for this purpose.
- Wood stoves. Install to the manufacturer’s clearances and local code, with a proper chimney, and put smoke and carbon monoxide alarms in any cabin with a stove. The EPA’s Burn Wise program covers choosing and running a wood stove safely.
- Wells. Hand-dug wells are dangerous to dig and easily contaminated. Most states license well drillers, and any new well should be tested for bacteria and nitrates before the water is drunk.
