“If you look into sustainable living there are so many people now realising how we can build homes & sheds out of recycled materials, from earthbags, tyres, sand bags and even pallets.
I have quite an interest in all this and there is a great website called The Natural Building Blog. Each day I get a newsletter from them with ideas of what is happening around the world with sustainable living.
This is a great idea for DIY low cost storage space. They’re simple enough anyone can build them. If you need a lot of shelving units, then it might be worthwhile to cut the cost in half by using 2x4s from oversized pallets (you’ll have to search around a bit to find them), and bolts or strong screws from yard sales or auctions. Bolts would be much easier to work with since it’s quite difficult to screw into old, dry pallet wood.
