Hereís a photo of an 8 by 8 backyard storage shed built a couple of years back for under $100. Most of the wood came from helicopter main rotor blade shipping containers or scrap pieces left over from various construction projects where I worked. Much of it was grayed and weathered but otherwise still sound. If it was destined for the land fill, I was given the opportunity to take it. I didnít have enough 2 x 4ís for all the wall studs and roof trusses, but I did have plenty of 8 foot long 3/8 inch plywood scraps that would otherwise have ended up at the land fill. So, I manufactured some of my own 2 x 4ís by ripping the scraps to 3 1/2 inches, then gluing and screw-nailing 4 strips together. The paint was $5.00/gallon mis-mixed color paint. The biggest expense was for two packages of asphalt shingles as I only had one package on hand that was left over when I re-roofed my house 5 years earlier.
