So why Eco-Shed?

So I have this big shed in our back yard, it's about 12ft x 14ft, looks like a little barn. Right now it's full of junk, just a big waste of space. I want to change that. I want it to be something, something Ecologically friendly, Economical too. I'm going to build us a mini farm, supply the house with fresh veggies, maybe some fish in some aquaponics, food storage the works. That's why it will be the Eco-Shed.
