Anyone have plans for a run in shed?

I am building a 12 ft by 12ft run in shed for 2 minis and possibly going to add a chicken coop on to it. Does any one have any plans to make a cheap run-in. I am buying rough cut lumber from a local mill and it has been a debate of have many boards to buy. I am not going to sink the post into the ground since it is frozen, I already have to torch the ground to put electric fence poles in. Also would you use wire or tape electric fence. So does anyone have plans to build a 12' x 12' run is shed with a pitched roof or a picture to give me an idea.
