Dude. Jealous of your vacation, although technically I had my week off two weeks ago in Florida. Also, could you expand on "alternative construction and design"? Sounds pretty interesting but honestly I don't quite know exactly what it is.
Yeah, I can't wait. Still got to work though, so it's pretty much a relocation for a couple weeks while I hang out in the Bahamas and drink cheap beer and rum. But instead of telecommuting from my boring ol' house I'll be on a balcony with ocean views, wind through my scraggly mane and drink in hand. Cuban cigars too, if I can find them. (In Puerto Rico last year I got 'Cuban Cigars' as in it was Cuban tobacco, but rolled in Puerto Rico. Legitimacy of that claim unknown.)
In regards to the alternative construction and design, it's always been a passion of mine. Creating homes that are not only affordable to build compared to traditional housing but also homes that are environmentally friendly and naturally energy efficient. Earthbag construction is the one I've researched the most, and most my home designs (see below) are designed with earthbag construction in mind. It's a relatively modern twist on primitive building methods. Think of it as a hybrid of adobe and rammed earth building. Utilizing polyethylene sacks (can acquire misprinted feed bags, burlap sacks, etc as alternatives) you would fill them with dirt, tamp them, lay them in a standard masonry style. Between each layer as the wall grows upward you'd add layers of barbed wire to prevent slipping and added tensile strength. The end result would be walls that are a foot and a half thick, of naturally energy effecient material. Resistant to fire and other natural disasters, naturally. I'd love to ride out a tornado in one of these.
The great thing about earthbag construction is you're not limited to typical straight edges and corners, you're free to build what you wish. Curves and domes are easily done with earthabgs. Once you've got your walls up, your home inside can be as traditional as any other house or as primitive as you wish. To protect the outside of the house from the elements, you'd place chicken wire on the outside of the bags surrounding the entire house. You'd attatch this to your earth-bags by nailing directly into them. This creates a surface for you to stucko your house. Some people use traditional siding, some will use hand harvested wood, some will buy plaster or cement whereas others just mix their own.
The benefits include cost effectiveness, the ability to build a home from the ground up with local materials at about 50-80% less than the cost of traditional construction. Naturally energy efficient, the thickness of the walls helps regulate temperature inside the home naturally, meaning an appropriately built home may be utilized without an additional heating or cooling to be a comfortable home year round. Depending on the climate will depend on how to properly build. If you build a monolithic home, meaning the walls AND ceiling are earthbags (would require domed roofs) then you're in a home that will withstand fire, earthquakes, tornados, hurricanes, etc. I believe it was the University of California that did testing on earthbag structures for their resistance to earthquakes. They scored so well that they actually broke the machine administering the test.
The downsides include the labor involved. Each bag with dirt can weigh 80lbs or more. Not all areas have codes in place to legally build an earthbag home, though the South West in America is more friendly towards this. May require additional upkeep on the OUTSIDE, if you live in an area that wears out your outer siding more.
These designs are all years old, I made them when I was 19-20 (going on 25 now). But these are just some random home designs I made in Sketchup when I was bored:
Entrance to a log frame partially earth bermed house with a 'living roof.'
Another view of the design above. Disregard the ramp, I rode BMX for many years and a lot of my designs included a ramp at home. Greenhouse attaches to kitchen.
Earthbag retaining wall and greenhouse entrance from the outside.
The ridiculously over built interior.
Here is another concept design of a earthbermed/partially underground earthbag home. Lot of my designs include living roofs and attached greenhouses.
Side view of another concept house.
This is supposedly in a southern facing hillside. Lot of flaws with this, light tubes rarely work well and the 'jungle gym' looking window would never work well. There is a greenhouse at the bottom and top of the house. Note the dog house
Unfinished design. Wonky.
Interior section from the design listed prior to this.
I'm a fan of SMALL and efficient designs. This is a little design I made up for a small, but livable home.
Not much, but it'd do the trick.
Kitchen area.
Side view.
Back view.
I used to have a TON more designs, some I were really proud of. But due to the 'great hard drive failure of 09', I've lost practically all of my designs. I don't even have the files for these anymore, I had to scrape these from an old photobucket account of mine. I haven't designed anything in a while.
