Okay, so you've got your eye on a piece of property that has a 3 bdrm/1.5 bath house on it, 17 acres of land, a barn, an all season creek (fresh water is going to be increasingly more important), and is divided between 5 acres of cleared pasture/farmland and the rest in timber that you can mill or sell.
We've already learned that one of the best small farm practices is to use no more than three acres for crops and flowers. So what else can you do with all that land?
How about greatly increasing the equity of your "empire" by adding another structure to it? Building Green and "Alternative" allows you to creative wonderful, mortgage-free buildings at pennies to what traditional buildings cost. The building can be wood burning Sauna cordwood building or a Strawbale "Adobe" home that keeps you warmer in the winter and cooler in the summer while decreasing your dependence on both energy and energy companies.
The latest ... and the building style that has recently caught my eye is Papercrete .... a substance that creates lightweight "concrete-ish" mix or "adobe-ish" blocks to build with.
Like cordwood homes, you don't have to be a builder to build a house. There are books and videos at your local public library. You can begin your search by clicking on the links and by googling some keywords like: alternative building, papercrete, cordwood building, strawbale houses, and building with cob.
